    // 查看是否授权
    wx.getSetting({

getUserInfo: async function(e) {
 debugger;
var  openid = app.globalData.openid;
var username = e.detail.userInfo.nickName;
var photo = e.detail.userInfo.avatarUrl;
var gender =  e.detail.userInfo.gender;

在开发工具上 可以弹出授权框 让用户选择同意还是不同意，

但是发布以后再手机上不会弹出， 然后直接拿到用户名  “微信用户”

然后头像拿不到
