微信小程序獲得微信頭像和昵稱

微信小程序之登錄態的探索

{
  wx.getSetting({
    success: res => {
      if (res.authSetting && res.authSetting['scope.userInfo']) {
        // 已經授權，可以直接調用 getUserInfo 獲取頭像昵稱
        wx.getUserInfo({
          success: function (data) {
            console.log(data.userInfo);
            // {
            //   avatarUrl: '微信頭像img文件path'
            //   nickname: '微信昵稱'
            // }
          }
        });
      } else {
        this.showShouquan = true; // 打開模態框進行授權
      }
    }
  });
}

    <div>
        <!-- 這里采用vantui進行彈框，只不過把彈出框的button類型設置成了"getUserInfo"，原理就是下面這個button
        <button wx:if="{{showShouquan}}" open-type="getUserInfo" bindgetuserinfo="getUserInfoFromWx">授權登錄</button> -->

                xxxxxxx小程序將獲得您的微信頭像、昵稱等公開消息
