gorilla/sessions provides cookie and filesystem sessions and infrastructure for
|
|
custom session backends.
|
|
|
|
The key features are:
|
|
|
|
- Simple API: use it as an easy way to set signed (and optionally
|
|
encrypted) cookies.
|
|
- Built-in backends to store sessions in cookies or the filesystem.
|
|
- Flash messages: session values that last until read.
|
|
- Convenient way to switch session persistency (aka "remember me") and set
|
|
other attributes.
|
|
- Mechanism to rotate authentication and encryption keys.
|
|
- Multiple sessions per request, even using different backends.
|
|
- Interfaces and infrastructure for custom session backends: sessions from
|
|
different stores can be retrieved and batch-saved using a common API.
|
|
|
|
Let's start with an example that shows the sessions API in a nutshell:
|
|
|
|
```go
|
|
import (
|
|
"net/http"
|
|
"github.com/gorilla/sessions"
|
|
)
|
|
|
|
// Note: Don't store your key in your source code. Pass it via an
|
|
// environmental variable, or flag (or both), and don't accidentally commit it
|
|
// alongside your code. Ensure your key is sufficiently random - i.e. use Go's
|
|
// crypto/rand or securecookie.GenerateRandomKey(32) and persist the result.
|
|
var store = sessions.NewCookieStore([]byte(os.Getenv("SESSION_KEY")))
|
|
|
|
func MyHandler(w http.ResponseWriter, r *http.Request) {
|
|
// Get a session. We're ignoring the error resulted from decoding an
|
|
// existing session: Get() always returns a session, even if empty.
|
|
session, _ := store.Get(r, "session-name")
|
|
// Set some session values.
|
|
session.Values["foo"] = "bar"
|
|
session.Values[42] = 43
|
|
// Save it before we write to the response/return from the handler.
|
|
err := session.Save(r, w)
|
|
if err != nil {
|
|
http.Error(w, err.Error(), http.StatusInternalServerError)
|
|
return
|
|
}
|
|
}
|
|
```
|
|
|
|
First we initialize a session store calling `NewCookieStore()` and passing a
|
|
secret key used to authenticate the session. Inside the handler, we call
|
|
`store.Get()` to retrieve an existing session or create a new one. Then we set
|
|
some session values in session.Values, which is a `map[interface{}]interface{}`.
|
|
And finally we call `session.Save()` to save the session in the response.
|

|
|
website](https://www.gorillatoolkit.org/pkg/sessions).
