**由于golang官方没有提供session标准库，我们在开发过程中会遇到session处理的问题，今天笔者推荐我写的一个库给大家使用~谢谢。**
- 支持session 增删改查操作
- 支持单机内存存储
- 支持分布式存储
- 分布式Redis存储
## Use Example
1. go get package 使用下面命令安装这个库
`go get -u github.com/higker/go-session`
2. Example Code 使用例子
```go
package main
import (
"fmt"
"github.com/higker/go-session"
"log"
"net/http"
)
func init() {
cfg := session.Config{
CookieName: session.DefaultCookieName,
Path: "/",
MaxAge: session.DefaultMaxAge,
HttpOnly: true,
Secure: false,
RedisAddr: "128.199.155.162:6379",
RedisPassword: "your password",
RedisDB: 0,
RedisKeyPrefix: session.RedisPrefix,
}
err := session.Builder(session.Redis, &cfg)
if err != nil {
log.Fatal(err)
}
// Memory store 使用内存存储方式就使用下面这个 注释上面的 打开下面的
// It is not recommended that you use it because it consumes memory
//err := session.Builder(session.Memory, session.DefaultCfg())
//if err != nil {
// log.Fatal(err)
//}
}
type User struct {
Name string `json:"name"`
Age int8 `json:"age"`
}
func main() {
http.HandleFunc("/", index)
http.HandleFunc("/set", set)
http.HandleFunc("/get", get)
http.HandleFunc("/del", del)
http.HandleFunc("/clean", clean)
http.ListenAndServe(":8080", nil)
}
func set(writer http.ResponseWriter, request *http.Request) {
ctx, err := session.Ctx(writer, request)
if err != nil {
log.Println(err)
}
// set data for session
user := User{Name: "Ding", Age: 21}
ctx.Set("K1", user)
fmt.Fprintln(writer, "set value ok")
}
func get(writer http.ResponseWriter, request *http.Request) {
ctx, err := session.Ctx(writer, request)
if err != nil {
log.Println(err)
}
bytes, err := ctx.Get("K1")
if err != nil {
log.Println("ERR", err)
}
u := new(User)
//Deserialize data into objects
session.DeSerialize(bytes, &u)
fmt.Fprintln(writer, u)
}
func clean(writer http.ResponseWriter, request *http.Request) {
ctx, err := session.Ctx(writer, request)
if err != nil {
log.Println(err)
}
// clean session all data by session
ctx.Clean(writer)
fmt.Fprintln(writer, "clean data ok")
}
func del(writer http.ResponseWriter, request *http.Request) {
ctx, err := session.Ctx(writer, request)
if err != nil {
log.Println(err)
}
err = ctx.Del("K1")
if err != nil {
log.Println(err)
}
fmt.Fprintln(writer, "delete v1 successful")
}
func index(writer http.ResponseWriter, request *http.Request) {
writer.Header().Add("Content-Type", "text/html")
fmt.Fprintf(writer, `
Go session storage example:<br><br>
<a href="/set">Store key in session</a><br>
<a href="/get">Get key value from session</a><br>
<a href="/del">Destroy session</a>
<a href="/clean">Clean session</a>
<a href="https://github.com/higker/go-session">to github</a><br>`)
}
```
3. browser Testing ~ Goodluck????~
> 由于go官方没有提供session的标准库，所以笔者自己写了一个并且开源出来希望你帮助屏幕前需要的你，给个star吧~
