BasicAuth

Go实现

在头里设置WWW-Authenticate

返回401

func (webhandler) ServeHTTP(writer http.ResponseWriter, request *http.Request) {
    writer.Header().Set("WWW-Authenticate", `Basic realm="您必须输入用户名和密码"`)
    writer.WriteHeader(http.StatusUnauthorized)
}

func (webhandler) ServeHTTP(writer http.ResponseWriter, request *http.Request) {
    auth := request.Header.Get("Authorization") //获取Basic base64加密后的字段
    if auth == "" {
        writer.Header().Set("WWW-Authenticate", `Basic realm="您必须输入用户名和密码"`)
        writer.WriteHeader(http.StatusUnauthorized)
        return
    }
    auth_list := strings.Split(auth, " ")
    if len(auth_list) == 2 && auth_list[0] == "Basic"{
        res,err := base64.StdEncoding.DecodeString(auth_list[1])
        if err == nil && string(res) == "shenyi:123" { //输入的用户名和密码会用:隔开
            writer.Write([]byte("<h1>web1</h1>"))
            return
        }
    }
    writer.Write([]byte("用户名密码错误"))
}
