开放域使用getUserInfo获取未授权的用户数据，perlist里是openId数组，得到的res只有自己的数据

console.log("请求playerlist",perlist);

        wx.getUserInfo({

            openIdList:perlist,

            lang: 'zh_CN',

            success:function(res){

                console.log(res);

                var resdata = res.data;

            }.bind(this),

            fail:function(){

                console.error("通过openid获取用户信息失败");

            }.bind(this)

        })
