1、首先下载SDK包：

下载路径：https://pan.baidu.com/s/10LTgdf6dIsyD8aSb6lawlw

2、登录微信公众平台：

设置JS接口安全域名：

3、以Thinkphp3.2.3 为例，将包放入Verdor 文件夹中，并将插件取名为：jssdk

4、控制器：

 public function read(){Vendor ('jssdk.jssdk');$jssdk = new \JSSDK ('你的APPID','你的APPserver');$signPackage = $jssdk->GetsignPackage ();// 获取文章主键 ID$Int_id = I('id',0,'intval');if($Int_id === 0){$this->error('ID 错误');}$ArticleModel = D('NewsArticle');// 文章点击数自增一$ArticleModel->SetInc(['id'=>$Int_id]);$data = $ArticleModel->getOne(['id'=>$Int_id]);$this->assign('data',$data);$this->assign ( 'signPackage', $signPackage );$this->display('article');}

5、前端页面

<?php$arr = array('appId' => $signPackage["appId"], 'nonceStr' => $signPackage["nonceStr"],'timestamp' => $signPackage["timestamp"],'signature' => $signPackage["signature"]);
?>
<script src="http://res.wx.qq.com/open/js/jweixin-1.0.0.js"></script>  
<script>  
var url=window.location.href;
var img = "{$data['thumb']}";
wx.config({  
debug:false,
appId: "{$arr['appId']}",
timestamp: "{$arr['timestamp']}",
nonceStr: "{$arr['nonceStr']}",
signature: "{$arr['signature']}", 
url:url,
jsApiList: [  "onMenuShareTimeline",     //分享给好友  "onMenuShareAppMessage",   //分享到朋友圈  "onMenuShareQQ",           //分享到QQ  "onMenuShareWeibo",        //分享到微博
]
});  wx.ready(function (){  var shareData = {  title: "{$data['post_title']}",  desc: "{$data['post_excerpt']}",  link: url,  imgUrl: img,};wx.onMenuShareAppMessage(shareData);  wx.onMenuShareTimeline(shareData);  wx.onMenuShareQQ(shareData);  wx.onMenuShareWeibo(shareData); });  </script>
