Question

我有一个相对简单的 Firebase 函数，它只是创建一个对 API 的 https 请求，然后应该对数据库进行几次写入。然而，即使它成功完成了 API 调用（我可以在服务的调试器中看到），它总是导致错误：无法处理请求。

功能

  export const CreateNoonlightAlarm = functions.https.onRequest((request, response) => {
    const options = {
      host: noonlightURL,
      path: "/dispatch/v1/alarms",
      method: "POST",
      headers: {
        "Content-Type": "application/json",
        Accept: "application/json",
        Authorization: `Bearer ${noonlightToken}`,
      },
    };

    var req = https.request(options, (res) => {
      res.on("data", (response) => {
        let data = JSON.parse(response);

        const docRef = database
          .collection("systems")
          .doc(request.body.owner_id)
          .collection("alarms")
          .doc(data.id);

        docRef
          .set(data, { merge: true })
          .catch((error: any) => console.log("docRef:", error));

        const referenceRef = database
          .collection("alarmsToSystems")
          .doc(data.id);

        referenceRef
          .set({
            alarm_id: data.id,
            system_id: request.body.owner_id,
          })
          .catch((error: any) => console.log("referenceRef:", error));

        response.send(response);
      });
    });

    req.on("error", (e) => {
      response.send(e);
    });

    req.write(JSON.stringify(request.body));
    req.end();
  }
);

现在，我已经有一段时间了。我已尝试删除 res.on("data", (response) => {} 块中除 response.send(response); 之外的所有内容，但仍然收到错误消息。我还看到很多人在 Firebase 实际更新函数时遇到了问题，并说在运行 firebase init 之前再次运行 firebase deploy，但这对我来说仍然不起作用。我还控制台记录了 request.body.owner_id 和 data.id 之类的内容，以确保它们可读，而且确实如此。同一文件中的其他函数在调用时运行得非常好，并返回它们预期返回的内容。

我是否遗漏了什么让这个函数成功运行？

所以，在又一个小时的故障排除和一行一行的挖掘之后，我意识到了一些事情。你不能在同一个函数中将两个事物命名为相同的事物......结果永远不会很好。

在第 1 行中，我将 var config = PHPickerConfiguration() config.selectionLimit = 1 config.filter = PHPickerFilter.any(of: [.images, .livePhotos]) let picker_Photo = PHPickerViewController(configuration: config) picker_Photo.delegate = self let libCell = UIAction(title: "Photo Library", image: UIImage(systemName: "photo"), identifier: .none, discoverabilityTitle: .none) { (libAction) in if UIImagePickerController.isSourceTypeAvailable(.photoLibrary) { PHPhotoLibrary.requestAuthorization(for: .readWrite) { status in switch status { case .limited: DispatchQueue.main.async { // PHPhotoLibrary.shared().register(self) // PHPhotoLibrary.shared().presentLimitedLibraryPicker self.present(picker_Photo, animated: true, completion: nil) } case .authorized: DispatchQueue.main.async { self.present(picker_Photo, animated: true, completion: nil) } case .notDetermined: DispatchQueue.main.async { self.present(picker_Photo, animated: true, completion: nil) } case .restricted: self.view.sendConfirmationAlert(theTitle: "Photo Library Restricted", theMessage: "Photo Library access was previously denied. Please update your Settings to allow access.", buttonTitle: "Ok") case .denied: let settingsAlert = UIAlertController(title: "Photo Library Access Denied", message: "Photo Library access was previously denied. Please update your Settings to allow access.", preferredStyle: .alert) let settingsAction = UIAlertAction(title: "Go to Settings", style: .default) { ( action ) in let settingsUrl = URL(string: UIApplication.openSettingsURLString) UIApplication.shared.open(settingsUrl!, options: [:]) } let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) DispatchQueue.main.async { settingsAlert.addAction(settingsAction) settingsAlert.addAction(cancelAction) self.present(settingsAlert, animated: true) } default: return } } } } 中的第二个参数定义为 OnRequest()。在第 14 行，我再次将 response 定义为 response 中的参数。

因此，当我将第 14 行的 res.on() 更改为 response，然后每次相应地使用该变量时，该函数开始完全按照预期工作。更新后的代码可以在下面找到。
