主要问题是清了缓存也不弹，也不报错，然而没有经过过授权这一步，弹用户授权页面不出授权开关。整个就卡在这了

const userLogIn = (cb) => {

var count = 2;

var userInfo = {};

var err;

var done = () => {

count--;

if (count != 0) {

return;

}

cb(err, userInfo);

};

wx.login({

success: (res) => {

if (res.code) {

userInfo.jsCode = res.code;

done();

return;

}

err = "USER LOGIN ERROR";

done();

}

});

wx.getSetting({

success: (res) => {

if (res.authSetting['scope.userInfo']) {

wx.getUserInfo({

success: (res) => {

for (var i in res.userInfo) {

userInfo[i] = res.userInfo[i];

}

done();

}

});

return;

}

wx.authorize({

scope: "scope.userInfo",

success: (e) => {

console.log(e);

},

fail: (e) => {

console.log(e);

error("请同意授权才能查看您的会员卡哦^_^", () => {

wx.openSetting({

success: (res) => {

}

});

});

}

});

err = "USER SCOPE ERROR";

done();

}

});

};
