常规写法

一般我们用Golang原生写Web时,一般这样写

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.WriteHeader(200)
        w.Write([]byte("ok"))
    })
    http.ListenAndServe(":8080", nil)
}

如果需要特定的GET,POST,PUT,DELETE处理. 我们需要这样写.

func main() {
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        if r.Method != http.MethodPost {
            w.WriteHeader(http.StatusMethodNotAllowed)
            _, _ = w.Write([]byte(http.StatusText(http.StatusMethodNotAllowed)))
        }
        w.WriteHeader(http.StatusOK)
        w.Write([]byte(http.StatusText(http.StatusOK)))
    })
    http.ListenAndServe(":8080", nil)
}

gorestful简约写法

对以上方法操作进行了封装.

• github.com/yezihack/gorestful

import (
    "github.com/yezihack/gorestful"
    "net/http"
)

func main() {
    router := gorestful.New()
    router.GET("/", Ping)
    router.POST("/ping", Ping)
    router.PUT("/ping", Ping)
    router.PATCH("/ping", Ping)
    router.DELETE("/ping", Ping)
    router.HEAD("/ping", Ping)
    router.CONNECT("/ping", Ping)
    router.TRACE("/ping", Ping)
    http.ListenAndServe(":8080", router)
}

func Ping(w http.ResponseWriter, r *http.Request) {
    w.WriteHeader(http.StatusOK)
    w.Write([]byte(http.StatusText(http.StatusOK)))
}

推荐

不过最后还是推荐使用httprouter, 大名顶顶的Gin Web框架就是使用这个的. 自己写的,纯属学习.
