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"
|
||
|
|
)
|
||
|
|
|
||
|
|
var store = sessions.NewCookieStore([]byte("something-very-secret"))
|
||
|
|
|
||
|
|
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.
|
||
|
|
session.Save(r, w)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
Important Note: If you aren't using gorilla/mux, you need to wrap your handlers
|
||
|
|
with
|
||
|
|
[`context.ClearHandler`](http://www.gorillatoolkit.org/pkg/context#ClearHandler)
|
||
|
|
or else you will leak memory! An easy way to do this is to wrap the top-level
|
||
|
|
mux when calling http.ListenAndServe:
|
||
|
|
|
||
|
|
```go
|
||
|
|
http.ListenAndServe(":8080", context.ClearHandler(http.DefaultServeMux))
|
||
|
|
```
|
||
|
|
|
||
|
|
The ClearHandler function is provided by the gorilla/context package.
|
||
|
|
|
||
|
|
More examples are available [on the Gorilla
|
||
|
|
website](http://www.gorillatoolkit.org/pkg/sessions).
