wx.getUserInfo api 没有任何反应，不会进行任何回调，也没有错误信息反馈。

代码如下：

const wxLogin = () => new Promise((resolve, reject) => {

    wx.login({ success: resolve, fail: reject });

});

const wxUserInfo = () => new Promise((resolve, reject) => {

    let loginSuccess = code => {

            wx.getUserInfo({

                withCredentials: true,

                success: res => {

                console.log('wxUserInfo success', res);

                res.code = code;

                res.rawData = JSON.parse(res.rawData);

                resolve(res);

            },

            fail: error => {

                console.log('wxUserInfo fail', error);

                reject(error);

            }

        });

    };

    wxLogin().then(res => res.code).then(loginSuccess).catch(reject);

});
