jssdk/jssdk.phpjssdk/share.js

jssdk.php 代码如下

    appId = $appId;    $this->appSecret = $appSecret;    $this->url = $url;//2017-06-27  }  public function getSignPackage() {    $jsapiTicket = $this->getJsApiTicket();    // 注意 URL 一定要动态获取，不能 hardcode.    $protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ?

share.js代码如下

//url = location.href;var url = encodeURIComponent(window.location.href);//去掉签名$.ajax({    type: "get",    url: "../jssdk/jssdk.php?url=" + url,    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: ['chackJsApi', 'onMenuShareTimeline', 'onMenuShareAppMessage', 'onMenuShareQQ', 'onMenuShareWeibo', 'onMenuShareQZone']        });    },    error: function(data) {        alert("连接失败！");    }});wx.ready(function() {    var shareData = {        title: title,        desc: desc,        link: url,        imgUrl: img,        success: function(res) {            //分享成功        },        cancel: function(res) {            alert('已取消分享');        }    };    wx.onMenuShareAppMessage(shareData);    wx.onMenuShareTimeline(shareData);    wx.onMenuShareQQ(shareData);    wx.onMenuShareWeibo(shareData);    wx.onMenuShareQZone(shareData);});

部署方式 页面底部添加如下代码

在引用jweixin-1.0.0.js之前，重置define、require即可。

ps：请在jquery之后引入
