gRPC in 3 minutes (Go)
|
|
======================
|
|
|
|
BACKGROUND
|
|
-------------
|
|
For this sample, we've already generated the server and client stubs from [helloworld.proto](helloworld/helloworld/helloworld.proto).
|
|
|
|
PREREQUISITES
|
|
-------------
|
|
|
|
- This requires Go 1.4
|
|
- Requires that [GOPATH is set](https://golang.org/doc/code.html#GOPATH)
|
|
|
|
```
|
|
$ go help gopath
|
|
$ # ensure the PATH contains $GOPATH/bin
|
|
$ export PATH=$PATH:$GOPATH/bin
|
|
```
|
|
|
|
INSTALL
|
|
-------
|
|
|
|
```
|
|
$ go get -u google.golang.org/grpc/examples/helloworld/greeter_client
|
|
$ go get -u google.golang.org/grpc/examples/helloworld/greeter_server
|
|
```
|
|
|
|
TRY IT!
|
|
-------
|
|
|
|
- Run the server
|
|
|
|
```
|
|
$ greeter_server &
|
|
```
|
|
|
|
- Run the client
|
|
|
|
```
|
|
$ greeter_client
|
|
```
|
|
|
|
OPTIONAL - Rebuilding the generated code
|
|
----------------------------------------
|
|
|
|
1 First [install protoc](https://github.com/google/protobuf/blob/master/README.md)
|
|
- For now, this needs to be installed from source
|
|
- This is will change once proto3 is officially released
|
|
|
|
2 Install the protoc Go plugin.
|
|
|
|
```
|
|
$ go get -a github.com/golang/protobuf/protoc-gen-go
|
|
$
|
|
$ # from this dir; invoke protoc
|
|
$ protoc -I ./helloworld/helloworld/ ./helloworld/helloworld/helloworld.proto --go_out=plugins=grpc:helloworld
|
|
```
