朋友圈   from=timeline&isappinstalled=0
微信群   from=groupmessage&isappinstalled=0
好友分享 from=singlemessage&isappinstalled=0

 

在连接后加上?&再进行分享，分享成功

url中红色链接内容，是微信自动为分享链接添加的内容，目的是为了记录分享来源

//js获取url中参数值的方法
function getQueryString(name) {
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
        var r = window.location.search.substr(1).match(reg);
        if (r != null)
            return unescape(r[2]);
        return null;
    }
    
  //二次分享时，微信会自动在url后加上&from=singlemessage&isappinstalled=0
