1 開發條件

1 申請一個微信公眾號，並確認在開發–接口權限中擁有分享功能的權限。
2 公眾號設置–功能設置：在JS接口安全域名中添加安全域名，這個安全域名不是url，只需添加一級域名即可。
3 開發，基本配置中，需要獲得開發者id，開發者密碼，ip白名單，ip白名單是服務器的ip。
4 獲得jsapi_ticket：
先獲取access_token:https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421140183
接口調用獲取：https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET
參數 說明
grant_type 獲取access_token填寫client_credential
appid 第三方用戶唯一憑證
secret 第三方用戶唯一憑證密鑰，即appsecret

獲取jsapi_ticket https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141115
5 signature獲取：
jsapi_ticket=sM4AOVdWfPE4DxkXGEs8VMCPGGVi4C3VM0P37wVUCFvkVAy_90u5h9nbSlYy3-Sl-HhTdfl2fzFy1AOcHKP7qg&noncestr=Wm3WZYTPz0wzccnW&timestamp=1414587457&url=http://mp.weixin.qq.com?params=value

2 在后台使用動態url方式獲取signature

前台：

 $(document).ready(function(){
    initPage();
    });
    function initPage() {
    //alert(window.location.href);/***用於獲得當前連接url用**/
    /***用戶點擊分享到微信圈后加載接口接口*******/
    $.post("/business/businessAction.do?method=getSharData",{"url":location.href.split('#')[0]},function(data,status){
            data=eval("("+data+")");
            console.log(data);
            wx.config({
                      debug: false,
                      appId: 'wx071f25226923fc00',
                      timestamp:data.timestamp,
                      nonceStr:data.nonceStr,
                      signature:data.signature,
                      jsApiList: [
                          'checkJsApi',
                          'onMenuShareTimeline',
                          'onMenuShareAppMessage',
                          'hideOptionMenu',
                      ]
                  });
             wx.ready(function(){
                wx.hideOptionMenu();/***隱藏分享菜單****/ 
            }); 
        });

    };
