【用户授权设计】java第三方登录（微博，QQ）详细代码

来源：互联网发布：Ubuntu 12 开机启动编辑：程序博客网时间：2024/06/08 13:12

第三方登录流程是：先获取code---->然后获取access_token----->根据token获取用户信息。

前台页面实现步骤：点击微博登录按钮---->打开一个子窗口，进行授权------>授权完成，跳转到首页或上次浏览的页面。

1、写第三方登录的按钮，点击按钮时，打开一个子窗口。

redirect_uri是你在微博上设置的回调地址。

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>    <title>My JSP 'index.jsp' starting page</title>    <meta http-equiv="pragma" content="no-cache">    <meta http-equiv="cache-control" content="no-cache">    <meta http-equiv="expires" content="0">        <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">    <meta http-equiv="description" content="This is my page">    <script type="text/javascript" src="http://statics.2cto.com/js/jquery.min.js"></script>  </head>  <script type="text/javascript">        var qqAuthWin,weiboAuthWin;            /**     * 关闭QQ子窗口     */    function closeQQWin(){        var result = $("#qq").val();        if(result != ""){            console.log(result);            qqAuthWin.close();        }else{            console.log("值为空");        }    }          /**     * QQ登录     * http://localhost:9090/logback/qq.jsp  QQ互联上设置的回调地址     */      function loginQQ(){          qqAuthWin = window.open("https://graph.qq.com/oauth2.0/authorize?response_type=code&client_id=CLIENT_ID&state=register&redirect_uri=http://localhost:9090/logback/qq.jsp",                    'QQ授权登录','width=770,height=600,menubar=0,scrollbars=1,'+                   'resizable=1,status=1,titlebar=0,toolbar=0,location=1');      }          /**     * 关闭微博子窗口     */    function closeWeiboWin(){        var result = $("#weibo").val();        if(result != ""){            console.log(result);            weiboAuthWin.close();        }else{            console.log("值为空");        }    }          /**     * 微博登录     * http://localhost:9090/logback/weibo.jsp这个就是在微博上设置的回调地址     */      function loginWeibo(){          weiboAuthWin = window.open("https://api.weibo.com/oauth2/authorize?client_id=CLIENT_ID&response_type=code&state=register&redirect_uri=http://localhost:9090/logback/weibo.jsp",                    '微博授权登录','width=770,height=600,menubar=0,scrollbars=1,'+           'resizable=1,status=1,titlebar=0,toolbar=0,location=1');      }  </script>  <body>      <input type="hidden" id="qq" value="">    <a  href="#" onClick="loginQQ()">QQ登录</a>        <br><br>    <hr>    <br>        <input type="hidden" id="weibo" value="">    <a href="#" onClick="loginWeibo()">微博登录</a>  </body></html>

2、回调地址页（qq.jsp、weibo.jsp）

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><%String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";String code = request.getParameter("code");//获取QQ返回的codeString state = request.getParameter("state");%><!DOCTYPE HTML><html>  <head>    <base href="<%=basePath%>">        <title>My JSP 'weibo.jsp' starting page</title>        <meta http-equiv="pragma" content="no-cache">    <meta http-equiv="cache-control" content="no-cache">    <meta http-equiv="expires" content="0">        <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">    <meta http-equiv="description" content="This is my page">    <script type="text/javascript" src="http://statics.2cto.com/js/jquery.min.js"></script>    <script>        $(function(){                var code = "<%=code%>";                var state = "<%=state%>";                $.ajax({                    url:"http://localhost:8080/cms_manage/api/qqLogin",                    type:"post",                    data:{code:code,state:state},                    dataType:"json",                    success:function(result){                        result = JSON.stringify(result);                        console.log(result);                        //把返回的数据传给父窗口的隐藏域中                        window.opener.document.getElementById("qq").value = result;                        //授权完成后，关闭子窗口                        window.opener.closeQQWin();                    }                });        });    </script>  </head>    <body>        登录成功。  </body></html>

qq.jsp和weibo,jsp是一样的。。。
