微信小程序在用户拒绝授权后无法使用wx.opensetting再次获取定位授权

 _getLocation(callback,errCall) {
      if (app.globalData.isLocationIng) {
        setTimeout(() => {
          this._getLocation(callback);
        }, 100);

            app.globalData.isLocationIng = false;
            errCall && errCall({ type: 'permanent_deny' });
            return;
          }

          if (!resData.authSetting["scope.userLocation"]) {

              //此方法无用，因为微信不允许在异步回调中直接调用 wx.openSetting，必须由用户主动触发(如点击按钮)，所以直接在_getLocation方法里进行处理

在myhehavior组件里无法在用户已经拒绝授权后再调用wx.opensetting()。wx.opensetting()必须由用户主动触发(如点击按钮)，不能在wx.getLocation 的fail 回调中直接调用。这是为了防止开发者强制跳转设置页干扰用户，所以我直接在getlocation里直接增加二次确认弹窗，为了防止用户第一次拒绝定位授权。
