session
A efficient, safely and easy-to-use session library for Go.
Quick Start
Download and install
go get -v github.com/go-session/session/v3
Create file server.go
package main
import (
"context"
"fmt"
"net/http"
session "github.com/go-session/session/v3"
)
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
store, err := session.Start(context.Background(), w, r)
if err != nil {
fmt.Fprint(w, err)
return
}
store.Set("foo", "bar")
err = store.Save()
if err != nil {
fmt.Fprint(w, err)
return
}
http.Redirect(w, r, "/foo", 302)
})
http.HandleFunc("/foo", func(w http.ResponseWriter, r *http.Request) {
store, err := session.Start(context.Background(), w, r)
if err != nil {
fmt.Fprint(w, err)
return
}
foo, ok := store.Get("foo")
if ok {
fmt.Fprintf(w, "foo:%s", foo)
return
}
fmt.Fprint(w, "does not exist")
})
http.ListenAndServe(":8080", nil)
}
Build and run
go build server.go
./server
Open in your web browser
foo:bar
Features
- Easy to use
- Multi-storage support
- Multi-middleware support
- More secure, signature-based tamper-proof
- Context support
- Support request header and query parameters

Overview ¶
Package session implements a efficient, safely and easy-to-use session library for Go.
Example:
package main
import (
"context"
"fmt"
"net/http"
session "github.com/go-session/session/v3"
)
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
store, err := session.Start(context.Background(), w, r)
if err != nil {
fmt.Fprint(w, err)
return
}
store.Set("foo", "bar")
err = store.Save()
if err != nil {
fmt.Fprint(w, err)
return
}
http.Redirect(w, r, "/foo", 302)
})
http.HandleFunc("/foo", func(w http.ResponseWriter, r *http.Request) {
store, err := session.Start(context.Background(), w, r)
if err != nil {
fmt.Fprint(w, err)
return
}
foo, ok := store.Get("foo")
if ok {
fmt.Fprintf(w, "foo:%s", foo)
return
}
fmt.Fprint(w, "does not exist")
})
http.ListenAndServe(":8080", nil)
}
Open in your web browser at http://localhost:8080
Output:
foo:bar

Functions ¶
func FromReqContext ¶
FromReqContext returns the Request value stored in ctx, if any.
func FromResContext ¶
func FromResContext(ctx context.Context) (http.ResponseWriter, bool)
FromResContext returns the ResponseWriter value stored in ctx, if any.
func InitManager ¶
func InitManager(opt ...Option)
