go原生读取cookie

package main

import (

    "net/http"
    "strings"
)

func mian() {
    http.HandleFunc("/", cookie)
    http.ListenAndServe(":8080", nil)

        Value:  "hello",
        Path:   "/",          //路径根目录
        Domain: "localhosst", //域名
        MaxAge: 120,
    }
    http.SetCookie(w, ck)            //设置cookie,ck是cookie
    ck2, err := r.Cookie("mycookie") //读取cookie
    if err != nil {
        io.WriteString(w, err.Error())
        return
    }

    }
    w.Header().Set("Set-Cookie", ck.String())                                  //通过Header设置cookie

go原生解析表单


package main

//直接使用go模仿beego解析表单,在src下建立一个文件夹test,
//test里面就放一个main.go。通过git Bash进入到该目录，
//go run main.go
import (
    "fmt"
    //"io"
    "html/template"
    "net/http"
)

func main() {
    http.HandleFunc("/", Hey)
    http.ListenAndServe(":8080", nil)
}

const tpl = `
<html>
    <head>
        <title>hey</title>
    </head>
    <body>
        <form method="POST" action="/">
           name: <input name="name" id="name"/>
           pwd: <input name="pwd" id="pwd"/>
                <input type="submit">ok</input>
        </form>
    </body>
</html>
`

func Hey(w http.ResponseWriter, r *http.Request) {
    //前面不加*号是接口，后面加*号是struct，要传地址，
    //只有这种签名的函数才能够注册为handler
    // fmt.Println("llllll")
    // io.WriteString("ssssssssfffffff)
    if r.Method == "GET" { //get请求的时候返回html
        t := template.New("hey")
        t.Parse(tpl)
        t.Execute(w, nil)
    } else { //post请求的时候解析form
        fmt.Println(r.FormValue("name"))
    }
}
