网站有自己的账号系统，这里使用的第三方登录仅仅是获取第三方账号的唯一id，昵称，性别进行本网站的自动注册。

自行到QQ，人人网和新浪微博的开发平台申请并获得对应的app

在做人人网的连接时审核了3次才通过：

引入qq的js

<script type="text/javascript" src="http://qzonestyle.gtimg.cn/qzone/openapi/qc_loader.js" data-appid="你申请的id"  charset="utf-8"></script>
<script type="text/javascript" src="http://qzonestyle.gtimg.cn/qzone/openapi/qc_loader.js" charset="utf-8" data-callback="true"></script>

不需要按照官网的做法，登录的做法也不过是跳转的一个链接而已，改为自己相应的参数就可以：

<tr>
    <td align="right" style="font-size:12px;">其他方式：</td>
    <td class="loginap">
        <% string href1 = "http://openapi.qzone.qq.com/oauth/show?which=ConfirmPage&display=pc&client_id=你申请的id&redirect_uri=http://www.pp6.cn/Login.aspx?type=qq_true_" + url + "&response_type=token&scope=all";
            string href2 = "http://graph.renren.com/oauth/grant?client_id=你申请的id&redirect_uri=http://www.pp6.cn/Login.aspx?type=rr_true_" + url.Replace("?","%3F") + "&response_type=code&display=page&secure=true&origin=00000";
            string href3 = "https://api.weibo.com/oauth2/authorize?client_id=你申请的id&redirect_uri=http://www.pp6.cn/Login.aspx?type=sina_true_" + url + "&response_type=code&state=2";
        %>
        <a href="<%=href1 %>" class="qqicon" title="QQ登录"></a>
        <a href="<%=href2 %>" class="rricon" title="人人登录"></a>
        <a href="<%=href3 %>" class="sinaicon" title="新浪登录"></a>
    </td>
</tr>

获取信息并注册：

    <script type="text/javascript">

                        $("#qqLoginBtn").hide();
                        QC.Login.signOut(); //马上注销qq的登录，改而使用本网站的账号系统

            document.cookie = name + "=a; expires=" + date.toGMTString();
        }

密码就随机生成好了：

      function randomPassword(length, special) {
          var iteration = 0;
          var password = "";
          var randomNumber;
          if (special == undefined) {
              var special = false;
          }
          while (iteration < length) {
              randomNumber = (Math.floor((Math.random() * 100)) % 94) + 33;
              if (!special) {
                  if ((randomNumber >= 33) && (randomNumber <= 47)) { continue; }
                  if ((randomNumber >= 58) && (randomNumber <= 64)) { continue; }
                  if ((randomNumber >= 91) && (randomNumber <= 96)) { continue; }
                  if ((randomNumber >= 123) && (randomNumber <= 126)) { continue; }
              }
              iteration++;
              password += String.fromCharCode(randomNumber);
          }
          return password;
      }

人人网和新浪微博的登录信息获取，不像qq那样直接使用js获取，而是使用第三方的sdk获取的：

        protected string isShow = GameRequest.GetQueryString("isShow");
        protected string type = GameRequest.GetQueryString("type");

        protected string imageurl = "";
        protected string sex = "";
        protected string error = "";

            sHeader.title = "会员中心";
            if (url == "" || url==null) url = "/Member/MIndex.aspx";
            if (isShow == "" || isShow == null) isShow = "false";
            if (code == "" || code == null) code = "";

            if (values.Length == )

回调页有参数怎么办？连续多个参数可能无法获取，所以这里把参数合并到一个参数里面：

"http://www.pp6.cn/Login.aspx?type=sina_true_" + url; 

再在后台把他们分隔开来：

            string[] values = type.Split('_');
            if (values.Length == )
            {
                type = values[];
                isShow = values[];
                url = values[];
            }

这里的参数type表示是使用何种方式登录，isShow指示是否弹出遮罩层，url才是我们真正想跳转的链接，至于redirect_uri是我们获取信息的代码功能页面：

redirect_uri=http://www.pp6.cn/Login.aspx

可以把AppKey写到web.config文件里面
