我正在尝试让AngularJS与Gorilla CSRF一起使用我的网络应用程序,但是我找不到很多文档,所以我不确定从哪里开始.我应该X-CSRF-Token为每个GET请求设置一个,还是应该在用户访问主页时执行此操作,就像我现在正在做的那样?另外,如何使用Gorilla CSRF使AngularJS CSRF保护工作?我需要进行某种比较吗?任何示例代码将不胜感激.
这是我的代码:

r := mux.NewRouter()
r.HandleFunc("/", Home).Methods("GET")

Run Code Online (Sandbox Code Playgroud) 来自PHP背景我对Gorilla会话包有点困惑.
Gorilla的行为与PHP 相似$_SESSION['name']或类似$_COOKIE['name']吗?
我正在尝试使用两种方法为我的Go Web应用程序创建用户会话,但我不确定Gorilla会话是否是一个很好的包使用.我希望没有点击登录表单上的"记住我"按钮的用户在关闭浏览器后删除会话,而其他人都会有一个与之关联的cookie.那么Gorilla会话能够处理这两种情况,还是我应该在这种情况下使用其他东西?
