http cookie的定义

先来看下golang对cookie结构体的定义：

type Cookie struct {
        Name  string
        Value string

        Path       string    // optional
        Domain     string    // optional
        Expires    time.Time // optional
        RawExpires string    // for reading cookies only

        // MaxAge=0 means no 'Max-Age' attribute specified.
        // MaxAge<0 means delete cookie now, equivalently 'Max-Age: 0'
        // MaxAge>0 means Max-Age attribute present and given in seconds
        MaxAge   int
        Secure   bool
        HttpOnly bool
        Raw      string
        Unparsed []string // Raw text of unparsed attribute-value pairs
}

常用参数：

Name

Value

Domain

Expires

HttpOnly

SecureMaxAge

服务端设置cookie

了解的cookie的属性，我们可以在服务端对cookie进行设置。

COOKIE_MAX_MAX_AGE     = time.Hour * 24 / time.Second   // 单位：秒。
maxAge = int(COOKIE_MAX_MAX_AGE)
uid:="10"

uid_cookie:=&http.Cookie{
		Name:   "uid",
		Value:    uid,
		Path:     "/",
		HttpOnly: false,
		MaxAge:   maxAge
	}

http.SetCookie(c.Writer,uid_cookie)

浏览器记录cookie

服务端获取cookie

var c  = *gin.Context
uid, err := c.Request.Cookie("uid")
