# Authentication
As outlined in the [gRPC authentication guide](http://www.grpc.io/docs/guides/auth.html) there are a number of different mechanisms for asserting identity between an client and server. We'll present some code-samples here demonstrating how to provide TLS support encryption and identity assertions as well as passing OAuth2 tokens to services that support it.
# Enabling TLS on a gRPC client
```Go
conn, err := grpc.Dial(serverAddr, grpc.WithTransportCredentials(credentials.NewClientTLSFromCert(nil, "")))
```
# Enabling TLS on a gRPC server
```Go
creds, err := credentials.NewServerTLSFromFile(certFile, keyFile)
if err != nil {
log.Fatalf("Failed to generate credentials %v", err)
}
lis, err := net.Listen("tcp", ":0")
server := grpc.NewServer(grpc.Creds(creds))
...
server.Serve(lis)
```
# Authenticating with Google
## Google Compute Engine (GCE)
```Go
conn, err := grpc.Dial(serverAddr, grpc.WithTransportCredentials(credentials.NewClientTLSFromCert(nil, ""), grpc.WithPerRPCCredentials(oauth.NewComputeEngine())))
```
## JWT
```Go
jwtCreds, err := oauth.NewServiceAccountFromFile(*serviceAccountKeyFile, *oauthScope)
if err != nil {
log.Fatalf("Failed to create JWT credentials: %v", err)
}
conn, err := grpc.Dial(serverAddr, grpc.WithTransportCredentials(credentials.NewClientTLSFromCert(nil, ""), grpc.WithPerRPCCredentials(jwtCreds)))
```

# Metadata
gRPC supports sending metadata between client and server.
This doc shows how to send and receive metadata in gRPC-go.
## Background
Four kinds of service method:

- [Server streaming RPC](http://www.grpc.io/docs/guides/concepts.html#server-streaming-rpc)
- [Client streaming RPC](http://www.grpc.io/docs/guides/concepts.html#client-streaming-rpc)
- [Bidirectional streaming RPC](http://www.grpc.io/docs/guides/concepts.html#bidirectional-streaming-rpc)
And concept of [metadata](http://www.grpc.io/docs/guides/concepts.html#metadata).
## Constructing metadata
A metadata can be created using package [metadata](https://godoc.org/google.golang.org/grpc/metadata).
The type MD is actually a map from string to a list of strings:
```go
type MD map[string][]string
```
Metadata can be read like a normal map.
Note that the value type of this map is `[]string`,
so that users can attach multiple values using a single key.
### Creating a new metadata
A metadata can be created from a `map[string]string` using function `New`:
```go
md := metadata.New(map[string]string{"key1": "val1", "key2": "val2"})
```
Another way is to use `Pairs`.
Values with the same key will be merged into a list:
```go
md := metadata.Pairs(
"key1", "val1",
"key1", "val1-2", // "key1" will have map value []string{"val1", "val1-2"}
"key2", "val2",
)
```
__Note:__ all the keys will be automatically converted to lowercase,
so "key1" and "kEy1" will be the same key and their values will be merged into the same list.
This happens for both `New` and `Pairs`.
### Storing binary data in metadata
In metadata, keys are always strings. But values can be strings or binary data.
To store binary data value in metadata, simply add "-bin" surfix to the key.
The values with "-bin" surffixed keys will be encoded when creating the metadata:
```go
md := metadata.Pairs(
"key", "string value",
"key-bin", string([]byte{96, 102}), // this binary data will be encoded (base64) before sending
// and will be decoded after being transferred.
)
```
## Retrieving metadata from context
Metadata can be retrieved from context using `FromContext`:
```go
func (s *server) SomeRPC(ctx context.Context, in *pb.SomeRequest) (*pb.SomeResponse, err) {
md, ok := metadata.FromContext(ctx)
// do something with metadata
}
```
## Sending and receiving metadata - client side
[//]: # "TODO: uncomment next line after example source added"
[//]: # "Real metadata sending and receiving examples are available [here](TODO:example_dir)."
### Sending metadata
To send metadata to server, the client can wrap the metadata into a context using `NewContext`, and make the RPC with this context:
```go
md := metadata.Pairs("key", "val")
// create a new context with this metadata
ctx := metadata.NewContext(context.Background(), md)
// make unary RPC
response, err := client.SomeRPC(ctx, someRequest)
// or make streaming RPC
stream, err := client.SomeStreamingRPC(ctx)
```
### Receiving metadata
Metadata that a client can receive includes header and trailer.
#### Unary call
Header and trailer sent along with a unary call can be retrieved using function [Header](https://godoc.org/google.golang.org/grpc#Header) and [Trailer](https://godoc.org/google.golang.org/grpc#Trailer) in [CallOption](https://godoc.org/google.golang.org/grpc#CallOption):
```go
var header, trailer metadata.MD // variable to store header and trailer
r, err := client.SomeRPC(
ctx,
someRequest,
grpc.Header(&header), // will retrieve header
grpc.Trailer(&trailer), // will retrieve trailer
)
// do something with header and trailer
```
#### Streaming call
For streaming calls including:
- Server streaming RPC
- Client streaming RPC
- Bidirectional streaming RPC
Header and trailer can be retrieved from the returned stream using function `Header` and `Trailer` in interface [ClientStream](https://godoc.org/google.golang.org/grpc#ClientStream):
```go
stream, err := client.SomeStreamingRPC(ctx)
// retrieve header
header, err := stream.Header()
// retrieve trailer
trailer := stream.Trailer()
```
## Sending and receiving metadata - server side
[//]: # "TODO: uncomment next line after example source added"
[//]: # "Real metadata sending and receiving examples are available [here](TODO:example_dir)."
### Receiving metadata
To read metadata sent by the client, the server needs to retrieve it from RPC context.
If it is a unary call, the RPC handler's context can be used.
For streaming calls, the server needs to get context from the stream.
#### Unary call
```go
func (s *server) SomeRPC(ctx context.Context, in *pb.someRequest) (*pb.someResponse, error) {
md, ok := metadata.FromContext(ctx)
// do something with metadata
}
```
#### Streaming call
```go
func (s *server) SomeStreamingRPC(stream pb.Service_SomeStreamingRPCServer) error {
md, ok := metadata.FromContext(stream.Context()) // get context from stream
// do something with metadata
}
```
### Sending metadata
#### Unary call
To send header and trailer to client in unary call, the server can call [SendHeader](https://godoc.org/google.golang.org/grpc#SendHeader) and [SetTrailer](https://godoc.org/google.golang.org/grpc#SetTrailer) functions in module [grpc](https://godoc.org/google.golang.org/grpc).
These two functions take a context as the first parameter.
It should be the RPC handler's context or one derived from it:
```go
func (s *server) SomeRPC(ctx context.Context, in *pb.someRequest) (*pb.someResponse, error) {
// create and send header
header := metadata.Pairs("header-key", "val")
grpc.SendHeader(ctx, header)
// create and set trailer
trailer := metadata.Pairs("trailer-key", "val")
grpc.SetTrailer(ctx, trailer)
}
```
#### Streaming call
For streaming calls, header and trailer can be sent using function `SendHeader` and `SetTrailer` in interface [ServerStream](https://godoc.org/google.golang.org/grpc#ServerStream):
```go
func (s *server) SomeStreamingRPC(stream pb.Service_SomeStreamingRPCServer) error {
// create and send header
header := metadata.Pairs("header-key", "val")
stream.SendHeader(header)
// create and set trailer
trailer := metadata.Pairs("trailer-key", "val")
stream.SetTrailer(trailer)
}
```

//
// There is a fair bit of overlap between FailedPrecondition and

#gRPC Basics: Go
This tutorial provides a basic Go programmer's introduction to working with gRPC. By walking through this example you'll learn how to:
- Define a service in a .proto file.
- Generate server and client code using the protocol buffer compiler.
- Use the Go gRPC API to write a simple client and server for your service.
It assumes that you have read the [Getting started](https://github.com/grpc/grpc/tree/master/examples) guide and are familiar with [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). Note that the example in this tutorial uses the proto3 version of the protocol buffers language, which is currently in alpha release:you can find out more in the [proto3 language guide](https://developers.google.com/protocol-buffers/docs/proto3) and see the [release notes](https://github.com/google/protobuf/releases) for the new version in the protocol buffers Github repository.
This isn't a comprehensive guide to using gRPC in Go: more reference documentation is coming soon.
## Why use gRPC?
Our example is a simple route mapping application that lets clients get information about features on their route, create a summary of their route, and exchange route information such as traffic updates with the server and other clients.
With gRPC we can define our service once in a .proto file and implement clients and servers in any of gRPC's supported languages, which in turn can be run in environments ranging from servers inside Google to your own tablet - all the complexity of communication between different languages and environments is handled for you by gRPC. We also get all the advantages of working with protocol buffers, including efficient serialization, a simple IDL, and easy interface updating.
## Example code and setup
The example code for our tutorial is in [grpc/grpc-go/examples/route_guide](https://github.com/grpc/grpc-go/tree/master/examples/route_guide). To download the example, clone the `grpc-go` repository by running the following command:
```shell
$ go get google.golang.org/grpc
```
Then change your current directory to `grpc-go/examples/route_guide`:
```shell
$ cd $GOPATH/src/google.golang.org/grpc/examples/route_guide
```
You also should have the relevant tools installed to generate the server and client interface code - if you don't already, follow the setup instructions in [the Go quick start guide](examples/).
## Defining the service
Our first step (as you'll know from the [quick start](http://www.grpc.io/docs/#quick-start)) is to define the gRPC *service* and the method *request* and *response* types using [protocol buffers] (https://developers.google.com/protocol-buffers/docs/overview). You can see the complete .proto file in [`examples/route_guide/proto/route_guide.proto`](examples/route_guide/proto/route_guide.proto).
To define a service, you specify a named `service` in your .proto file:
```proto
service RouteGuide {
...
}
```
Then you define `rpc` methods inside your service definition, specifying their request and response types. gRPC lets you define four kinds of service method, all of which are used in the `RouteGuide` service:
- A *simple RPC* where the client sends a request to the server using the stub and waits for a response to come back, just like a normal function call.
```proto
// Obtains the feature at a given position.
rpc GetFeature(Point) returns (Feature) {}
```
- A *server-side streaming RPC* where the client sends a request to the server and gets a stream to read a sequence of messages back. The client reads from the returned stream until there are no more messages. As you can see in our example, you specify a server-side streaming method by placing the `stream` keyword before the *response* type.
```proto
// Obtains the Features available within the given Rectangle. Results are
// streamed rather than returned at once (e.g. in a response message with a
// repeated field), as the rectangle may cover a large area and contain a
// huge number of features.
rpc ListFeatures(Rectangle) returns (stream Feature) {}
```
- A *client-side streaming RPC* where the client writes a sequence of messages and sends them to the server, again using a provided stream. Once the client has finished writing the messages, it waits for the server to read them all and return its response. You specify a client-side streaming method by placing the `stream` keyword before the *request* type.
```proto
// Accepts a stream of Points on a route being traversed, returning a
// RouteSummary when traversal is completed.
rpc RecordRoute(stream Point) returns (RouteSummary) {}
```
- A *bidirectional streaming RPC* where both sides send a sequence of messages using a read-write stream. The two streams operate independently, so clients and servers can read and write in whatever order they like: for example, the server could wait to receive all the client messages before writing its responses, or it could alternately read a message then write a message, or some other combination of reads and writes. The order of messages in each stream is preserved. You specify this type of method by placing the `stream` keyword before both the request and the response.
```proto
// Accepts a stream of RouteNotes sent while a route is being traversed,
// while receiving other RouteNotes (e.g. from other users).
rpc RouteChat(stream RouteNote) returns (stream RouteNote) {}
```
Our .proto file also contains protocol buffer message type definitions for all the request and response types used in our service methods - for example, here's the `Point` message type:
```proto
// Points are represented as latitude-longitude pairs in the E7 representation
// (degrees multiplied by 10**7 and rounded to the nearest integer).
// Latitudes should be in the range +/- 90 degrees and longitude should be in
// the range +/- 180 degrees (inclusive).
message Point {
int32 latitude = 1;
int32 longitude = 2;
}
```
## Generating client and server code
Next we need to generate the gRPC client and server interfaces from our .proto service definition. We do this using the protocol buffer compiler `protoc` with a special gRPC Go plugin.
For simplicity, we've provided a [bash script](https://github.com/grpc/grpc-go/blob/master/codegen.sh) that runs `protoc` for you with the appropriate plugin, input, and output (if you want to run this by yourself, make sure you've installed protoc and followed the gRPC-Go [installation instructions](https://github.com/grpc/grpc-go/blob/master/README.md) first):
```shell
$ codegen.sh route_guide.proto
```
which actually runs:
```shell
$ protoc --go_out=plugins=grpc:. route_guide.proto
```
Running this command generates the following file in your current directory:
- `route_guide.pb.go`
This contains:
- All the protocol buffer code to populate, serialize, and retrieve our request and response message types
- An interface type (or *stub*) for clients to call with the methods defined in the `RouteGuide` service.
- An interface type for servers to implement, also with the methods defined in the `RouteGuide` service.
<a name="server"></a>
## Creating the server
First let's look at how we create a `RouteGuide` server. If you're only interested in creating gRPC clients, you can skip this section and go straight to [Creating the client](#client) (though you might find it interesting anyway!).
There are two parts to making our `RouteGuide` service do its job:
- Implementing the service interface generated from our service definition: doing the actual "work" of our service.
- Running a gRPC server to listen for requests from clients and dispatch them to the right service implementation.
You can find our example `RouteGuide` server in [grpc-go/examples/route_guide/server/server.go](https://github.com/grpc/grpc-go/tree/master/examples/route_guide/server/server.go). Let's take a closer look at how it works.
### Implementing RouteGuide
As you can see, our server has a `routeGuideServer` struct type that implements the generated `RouteGuideServer` interface:
```go
type routeGuideServer struct {
...
}
...
func (s *routeGuideServer) GetFeature(ctx context.Context, point *pb.Point) (*pb.Feature, error) {
...
}
...
func (s *routeGuideServer) ListFeatures(rect *pb.Rectangle, stream pb.RouteGuide_ListFeaturesServer) error {
...
}
...
func (s *routeGuideServer) RecordRoute(stream pb.RouteGuide_RecordRouteServer) error {
...
}
...
func (s *routeGuideServer) RouteChat(stream pb.RouteGuide_RouteChatServer) error {
...
}
...
```
#### Simple RPC
`routeGuideServer` implements all our service methods. Let's look at the simplest type first, `GetFeature`, which just gets a `Point` from the client and returns the corresponding feature information from its database in a `Feature`.
```go
func (s *routeGuideServer) GetFeature(ctx context.Context, point *pb.Point) (*pb.Feature, error) {
for _, feature := range s.savedFeatures {
if proto.Equal(feature.Location, point) {
return feature, nil
}
}
// No feature was found, return an unnamed feature
return &pb.Feature{"", point}, nil
}
```
The method is passed a context object for the RPC and the client's `Point` protocol buffer request. It returns a `Feature` protocol buffer object with the response information and an `error`. In the method we populate the `Feature` with the appropriate information, and then `return` it along with an `nil` error to tell gRPC that we've finished dealing with the RPC and that the `Feature` can be returned to the client.
#### Server-side streaming RPC
Now let's look at one of our streaming RPCs. `ListFeatures` is a server-side streaming RPC, so we need to send back multiple `Feature`s to our client.
```go
func (s *routeGuideServer) ListFeatures(rect *pb.Rectangle, stream pb.RouteGuide_ListFeaturesServer) error {
for _, feature := range s.savedFeatures {
if inRange(feature.Location, rect) {
if err := stream.Send(feature); err != nil {
return err
}
}
}
return nil
}
```
As you can see, instead of getting simple request and response objects in our method parameters, this time we get a request object (the `Rectangle` in which our client wants to find `Feature`s) and a special `RouteGuide_ListFeaturesServer` object to write our responses.
In the method, we populate as many `Feature` objects as we need to return, writing them to the `RouteGuide_ListFeaturesServer` using its `Send()` method. Finally, as in our simple RPC, we return a `nil` error to tell gRPC that we've finished writing responses. Should any error happen in this call, we return a non-`nil` error; the gRPC layer will translate it into an appropriate RPC status to be sent on the wire.
#### Client-side streaming RPC
Now let's look at something a little more complicated: the client-side streaming method `RecordRoute`, where we get a stream of `Point`s from the client and return a single `RouteSummary` with information about their trip. As you can see, this time the method doesn't have a request parameter at all. Instead, it gets a `RouteGuide_RecordRouteServer` stream, which the server can use to both read *and* write messages - it can receive client messages using its `Recv()` method and return its single response using its `SendAndClose()` method.
```go
func (s *routeGuideServer) RecordRoute(stream pb.RouteGuide_RecordRouteServer) error {
var pointCount, featureCount, distance int32
var lastPoint *pb.Point
startTime := time.Now()
for {
point, err := stream.Recv()
if err == io.EOF {
endTime := time.Now()
return stream.SendAndClose(&pb.RouteSummary{
PointCount: pointCount,
FeatureCount: featureCount,
Distance: distance,
ElapsedTime: int32(endTime.Sub(startTime).Seconds()),
})
}
if err != nil {
return err
}
pointCount++
for _, feature := range s.savedFeatures {
if proto.Equal(feature.Location, point) {
featureCount++
}
}
if lastPoint != nil {
distance += calcDistance(lastPoint, point)
}
lastPoint = point
}
}
```
In the method body we use the `RouteGuide_RecordRouteServer`s `Recv()` method to repeatedly read in our client's requests to a request object (in this case a `Point`) until there are no more messages: the server needs to check the the error returned from `Recv()` after each call. If this is `nil`, the stream is still good and it can continue reading; if it's `io.EOF` the message stream has ended and the server can return its `RouteSummary`. If it has any other value, we return the error "as is" so that it'll be translated to an RPC status by the gRPC layer.
#### Bidirectional streaming RPC
Finally, let's look at our bidirectional streaming RPC `RouteChat()`.
```go
func (s *routeGuideServer) RouteChat(stream pb.RouteGuide_RouteChatServer) error {
for {
in, err := stream.Recv()
if err == io.EOF {
return nil
}
if err != nil {
return err
}
key := serialize(in.Location)
... // look for notes to be sent to client
for _, note := range s.routeNotes[key] {
if err := stream.Send(note); err != nil {
return err
}
}
}
}
```
This time we get a `RouteGuide_RouteChatServer` stream that, as in our client-side streaming example, can be used to read and write messages. However, this time we return values via our method's stream while the client is still writing messages to *their* message stream.
The syntax for reading and writing here is very similar to our client-streaming method, except the server uses the stream's `Send()` method rather than `SendAndClose()` because it's writing multiple responses. Although each side will always get the other's messages in the order they were written, both the client and server can read and write in any order — the streams operate completely independently.
### Starting the server
Once we've implemented all our methods, we also need to start up a gRPC server so that clients can actually use our service. The following snippet shows how we do this for our `RouteGuide` service:
```go
flag.Parse()
lis, err := net.Listen("tcp", fmt.Sprintf(":%d", *port))
if err != nil {
log.Fatalf("failed to listen: %v", err)
}
grpcServer := grpc.NewServer()
pb.RegisterRouteGuideServer(grpcServer, &routeGuideServer{})
... // determine whether to use TLS
grpcServer.Serve(lis)
```
To build and start a server, we:
1. Specify the port we want to use to listen for client requests using `lis, err := net.Listen("tcp", fmt.Sprintf(":%d", *port))`.
2. Create an instance of the gRPC server using `grpc.NewServer()`.
3. Register our service implementation with the gRPC server.
4. Call `Serve()` on the server with our port details to do a blocking wait until the process is killed or `Stop()` is called.
<a name="client"></a>
## Creating the client
In this section, we'll look at creating a Go client for our `RouteGuide` service. You can see our complete example client code in [grpc-go/examples/route_guide/client/client.go](https://github.com/grpc/grpc-go/tree/master/examples/route_guide/client/client.go).
### Creating a stub
To call service methods, we first need to create a gRPC *channel* to communicate with the server. We create this by passing the server address and port number to `grpc.Dial()` as follows:
```go
conn, err := grpc.Dial(*serverAddr)
if err != nil {
...
}
defer conn.Close()
```
You can use `DialOptions` to set the auth credentials (e.g., TLS, GCE credentials, JWT credentials) in `grpc.Dial` if the service you request requires that - however, we don't need to do this for our `RouteGuide` service.
Once the gRPC *channel* is setup, we need a client *stub* to perform RPCs. We get this using the `NewRouteGuideClient` method provided in the `pb` package we generated from our .proto.
```go
client := pb.NewRouteGuideClient(conn)
```
### Calling service methods
Now let's look at how we call our service methods. Note that in gRPC-Go, RPCs operate in a blocking/synchronous mode, which means that the RPC call waits for the server to respond, and will either return a response or an error.
#### Simple RPC
Calling the simple RPC `GetFeature` is nearly as straightforward as calling a local method.
```go
feature, err := client.GetFeature(context.Background(), &pb.Point{409146138, -746188906})
if err != nil {
...
}
```
As you can see, we call the method on the stub we got earlier. In our method parameters we create and populate a request protocol buffer object (in our case `Point`). We also pass a `context.Context` object which lets us change our RPC's behaviour if necessary, such as time-out/cancel an RPC in flight. If the call doesn't return an error, then we can read the response information from the server from the first return value.
```go
log.Println(feature)
```
#### Server-side streaming RPC
Here's where we call the server-side streaming method `ListFeatures`, which returns a stream of geographical `Feature`s. If you've already read [Creating the server](#server) some of this may look very familiar - streaming RPCs are implemented in a similar way on both sides.
```go
rect := &pb.Rectangle{ ... } // initialize a pb.Rectangle
stream, err := client.ListFeatures(context.Background(), rect)
if err != nil {
...
}
for {
feature, err := stream.Recv()
if err == io.EOF {
break
}
if err != nil {
log.Fatalf("%v.ListFeatures(_) = _, %v", client, err)
}
log.Println(feature)
}
```
As in the simple RPC, we pass the method a context and a request. However, instead of getting a response object back, we get back an instance of `RouteGuide_ListFeaturesClient`. The client can use the `RouteGuide_ListFeaturesClient` stream to read the server's responses.
We use the `RouteGuide_ListFeaturesClient`'s `Recv()` method to repeatedly read in the server's responses to a response protocol buffer object (in this case a `Feature`) until there are no more messages: the client needs to check the error `err` returned from `Recv()` after each call. If `nil`, the stream is still good and it can continue reading; if it's `io.EOF` then the message stream has ended; otherwise there must be an RPC error, which is passed over through `err`.
#### Client-side streaming RPC
The client-side streaming method `RecordRoute` is similar to the server-side method, except that we only pass the method a context and get a `RouteGuide_RecordRouteClient` stream back, which we can use to both write *and* read messages.
```go
// Create a random number of random points
r := rand.New(rand.NewSource(time.Now().UnixNano()))
pointCount := int(r.Int31n(100)) + 2 // Traverse at least two points
var points []*pb.Point
for i := 0; i < pointCount; i++ {
points = append(points, randomPoint(r))
}
log.Printf("Traversing %d points.", len(points))
stream, err := client.RecordRoute(context.Background())
if err != nil {
log.Fatalf("%v.RecordRoute(_) = _, %v", client, err)
}
for _, point := range points {
if err := stream.Send(point); err != nil {
log.Fatalf("%v.Send(%v) = %v", stream, point, err)
}
}
reply, err := stream.CloseAndRecv()
if err != nil {
log.Fatalf("%v.CloseAndRecv() got error %v, want %v", stream, err, nil)
}
log.Printf("Route summary: %v", reply)
```
The `RouteGuide_RecordRouteClient` has a `Send()` method that we can use to send requests to the server. Once we've finished writing our client's requests to the stream using `Send()`, we need to call `CloseAndRecv()` on the stream to let gRPC know that we've finished writing and are expecting to receive a response. We get our RPC status from the `err` returned from `CloseAndRecv()`. If the status is `nil`, then the first return value from `CloseAndRecv()` will be a valid server response.
#### Bidirectional streaming RPC
Finally, let's look at our bidirectional streaming RPC `RouteChat()`. As in the case of `RecordRoute`, we only pass the method a context object and get back a stream that we can use to both write and read messages. However, this time we return values via our method's stream while the server is still writing messages to *their* message stream.
```go
stream, err := client.RouteChat(context.Background())
waitc := make(chan struct{})
go func() {
for {
in, err := stream.Recv()
if err == io.EOF {
// read done.
close(waitc)
return
}
if err != nil {
log.Fatalf("Failed to receive a note : %v", err)
}
log.Printf("Got message %s at point(%d, %d)", in.Message, in.Location.Latitude, in.Location.Longitude)
}
}()
for _, note := range notes {
if err := stream.Send(note); err != nil {
log.Fatalf("Failed to send a note: %v", err)
}
}
stream.CloseSend()
<-waitc
```
The syntax for reading and writing here is very similar to our client-side streaming method, except we use the stream's `CloseSend()` method once we've finished our call. Although each side will always get the other's messages in the order they were written, both the client and server can read and write in any order — the streams operate completely independently.
## Try it out!
To compile and run the server, assuming you are in the folder
`$GOPATH/src/google.golang.org/grpc/examples/route_guide`, simply:
```sh
$ go run server/server.go
```
Likewise, to run the client:
```sh
$ go run client/client.go
```
