微信小程序如何获取用户信息

wx.login({
 success:function(){
 wx.getUserInfo({
  success:function(res){
  var simpleUser = res.userInfo;
  console.log(simpleUser.nickName);
  }
 });
 }
});

    };
   request.httpsPostRequest(requestUrl,jsonData,function(res){
   console.log(res.openId);
   });
   }
  })
  }
 }
 })
