网络不佳时getSetting返回错误值

• 当前 Bug 的表现（可附上截图）

体验版中，网络信号不佳__时调用wx.getSetting()获取是否已授权__userinfo无法返回__或__返回错误值，网络条件好时一切正常。

1. Andriod 6.0.1

   10分钟内无法进入success/fail 任一回调函数
   

2. IOS 12

   进入success, 但res.authSetting["scope.userInfo"]是undefined，其实该用户已授权该信息。【这个非常坑，业务逻辑会引导用户再次授权而进入无限循环】

• 预期表现

网络信号不佳时调用wx.getSetting()进入fail回调。

• 复现路径

调用Demo

• 提供一个最简复现 Demo

function __request(url,bNeedAuth) {   return new Promise(function (resolve, reject) {     console.log('try to request url:' + url);           if(wx.canIUse("getSetting")){       wx.getSetting({         success(res) {           console.log('bNeedAuth is :' + bNeedAuth + ' res.authSetting["scope.userInfo"] is :' + (res.authSetting["scope.userInfo"]) );           if (bNeedAuth && !res.authSetting["scope.userInfo"]) {             //my logic             console.log('Not authorized!');             reject(new Error('not authorized !'));           }           else {             //2.send request             //wx.request()             //... other logic           }         },         fail(err){           console.log('call wx.getSetting error.');           console.log(err);           reject(err);         }       })     }     else{       let errMsg = 'wx.getSetting is not supported.';       console.log(errMsg);       reject(new Error(errMsg));     }   }) }
