WeChat Mini Program Location Permission Handling

Handle scenario where user denied scope.userLocation, guiding them to enable it again.

function ensureLocationAuth() {
  wx.getSetting({
    success(res) {
      if (!res.authSetting['scope.userLocation']) {
        wx.openSetting({
          success: (res2) => {
            if (!res2.authSetting['scope.userLocation']) {
              wx.showModal({
                title: 'Reminder',
                content: 'Location access is required to use this feature.',
                cancelText: 'Later',
                confirmText: 'Enable',
                success: (mRes) => {
                  if (mRes.confirm) {
                    ensureLocationAuth();
                  } else {
                    wx.showToast({
                      title: 'Tap the locate button below to retry later',
                      icon: 'success',
                      duration: 3000
                    });
                  }
                }
              });
            }
          }
        });
      }
    }
  });
}

Tips:

1. Avoid looping if user keeps denying—add backoff logic for production.
2. Provide a clear UI affordance (e.g. map pin button) to retry authorization.
3. Cache a sentinel flag after N denials to stop prompting.
