微信分享網(wǎng)頁的時候，希望分享出來的鏈接是標題+描述+縮略圖，微信開發(fā)代碼示例里已提供了方法，但只適用于動態(tài)頁面。我使用phpcms把頁面生成了靜態(tài)文件，示例代碼就起不到作用了。在網(wǎng)上找了下，有大神使用Ajax實現(xiàn)靜態(tài)頁面也能實現(xiàn)微信分享功能，在這里分享給大家。

前臺代碼：

<script src="http://res.wx.QQ.com/open/js/jweixin-1.0.0.js"></script><script>url=location.href;  $.ajax({    type : "get",    url : "http://xxxxxxxxx/jssdk.php?url="+url,//替換網(wǎng)址，xxx根據(jù)自己jssdk文件位置修改    dataType : "jsonp",    jsonp: "callback",    jsonpCallback:"success_jsonpCallback",    success : function(data){        wx.config({appId: data.appId,timestamp: data.timestamp,nonceStr: data.nonceStr,signature: data.signature,jsApiList: [       "onMenuShareTimeline", //分享給好友       "onMenuShareAppMessage", //分享到朋友圈       "onMenuShareQQ",  //分享到QQ       "onMenuShareWeibo" //分享到微博]});},                error:function(data){                    alert("連接失敗！");                }});  wx.ready(function (){  var shareData = {  title: '標題',  desc: '簡介',//這里請?zhí)貏e注意是要去除html  link: '鏈接',  imgUrl: '題圖'  };  wx.onMenuShareAppMessage(shareData);  wx.onMenuShareTimeline(shareData);  wx.onMenuShareQQ(shareData);  wx.onMenuShareWeibo(shareData);    });</script>記得把jquery的庫也加上去，否則ajax不會運行
修改服務(wù)端文件jssdk.php
<?php$url = $_GET['url'];class JSSDK {  PRivate $appId;  private $appSecret;  private $url;  public function __construct($appId, $appSecret,$url) {    $this->appId = $appId;    $this->appSecret = $appSecret;$this->url = $url;  }  public function getSignPackage() {    $jsapiTicket = $this->getJsApiTicket();    $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ?
