form action =“？login” ：问号是什么意思？ [英] form action="?login" : What does the question mark mean?

问题描述

 < form action =？loginmethod =post> <按钮>使用Google登录< / button> < /形式> 
  

我通常会看到这个动作引用了一个php或html文件，但？login让我感到困惑。

背景信息：
这是埋在lightopenid框架的example-google.php文件中。我一直盯着openid代码使用谷歌作为第三方openid提供者在我的网站上的用户登录和示例代码的所有作品。试图更清楚地了解当用户按下登录按钮时框架正在做什么。我知道我们必须向这个按钮动作发送一堆参数给谷歌，但登录似乎并没有指向任何地方。

解决方案

问号表示查询字符串。它将使用查询字符串参数 login 发布到当前url。我不确定在你点击提交（发布表单）后你是如何处理请求的，但通常它会为它赋值，如 login = value

<form action="?login" method="post">     <button>Login with Google</button> </form>

I usually see the action refer to a php or html file but the "?login" stumps me.

Background info: This is buried within the example-google.php file from lightopenid framework. I've been staring at the openid code to use google as a third party openid provider for user login on my web site and the sample code all works. Trying to get a clearer picture of what the framework is doing when the user presses the login button. I know that we must be sending a bunch of arguments to google on this button action but the ?login doesnt seem to point anywhere.

解决方案

a question mark denotes the query string. It will post to the current url with a query string parameter of login. I am not sure how you are processing the request after you click submit(post the form) but usually it would have a value assigned to it as in login=value
