如何将授权码从JSP传递到Servlet

发布于 2024-12-03 06:25:16 字数 694 浏览 0 评论 0原文

我已经束手无策了，7个小时还在继续。

我是 FB 开发新手，在将授权代码从 JSP 传递到 Servlet 时遇到问题。

1.) 我使用社交插件登录我的 JSP，如下所示

<fb:login-button>Login with Facebook</fb:login-button>

这将用户登录并允许他们授予我的应用程序访问其个人信息的权限

2.) 登录并授权后成功后，用户通过下面的代码从 JSP 转发到我的 servlet

 FB.Event.subscribe('auth.login', function (response) {
 window.location = "testservlet"; 
 });

3。）但是当我尝试在 Servlet 中获取授权代码（以便我可以获得 auth.token）时，“代码”为空，请参阅我用来检索下面的代码

String authCode = req.getParameter("code");

任何人都可以告诉我我做错了什么吗？我确信我错过了一些如此简单的事情..或者我正在尝试做超出必要的事情，提前致谢

I am at my wits end, 7 hours and counting.

I am new to FB development and am having an issue of passing the authorization code from my JSP to my Servlet.

1.) I use the social plugin for login in my JSP as shown below

<fb:login-button>Login with Facebook</fb:login-button>

This logs the user in and allows them to grant my app access to their personal information

2.) Once login and authorization are successful, the user is forwarded to my servlet from the JSP via the code below

 FB.Event.subscribe('auth.login', function (response) {
 window.location = "testservlet"; 
 });

3.) But when I attempt to get the authorization code (so that I can get the auth. token) in my Servlet, the "code" is empty, see the code I am using to retrieve below

String authCode = req.getParameter("code");

Can anyone tell me what I am doing wrong? I am sure that I am missing something so simple..or am trying to do more than is necessary, thanks in advance

我对 Facebook 开发不熟悉，但对于 servlet，window.location 通常来说不会带你到 servlet。
尝试使用jquery的ajax函数并传递一个“code”参数。做类似的事情：

$.ajax({
        url: yourServletPath+"testservlet",
        data:"code="+codevariable,
        dataType: "whatever data type your servlet returns",
        success: function(response) 
        {
          // wtv code to be done
        } 
      });

I am not familiar with Facebook dev, but concerning servlets, window.location normally speaking will not take you to a servlet.
try using jquery's ajax function and pass a "code" parameter. Do something like :

$.ajax({
        url: yourServletPath+"testservlet",
        data:"code="+codevariable,
        dataType: "whatever data type your servlet returns",
        success: function(response) 
        {
          // wtv code to be done
        } 
      });
