微信自定义分享支持https(php)

摘要：用户要分享的网址又更分享的标题分享的图片又更仅仅如此分享的描述信息请在之后引入

直接上代码

目录（jssdk在网站更目录）

jssdk/jssdk.php
jssdk/share.js

jssdk.php 代码如下

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
