只有HTTP(S)协议支持Firebase函数

Question

我已经复制了所有代码，包括来自Resize Image函数扩展的依赖项。我正在Firebase模拟器中运行这个程序，并且需要对它进行调整以满足我的需要。但是，就目前而言，我已经将其设置为几乎与扩展中的源代码完全相同的代码。

Ext网址：https://firebase.google.com/products/extensions/storage-resize-images

我的本地设置：

节点: v14.17.5

国家预防机制: 7.23.0

火力基数: 9.20.0

防火墙-管理：^9.11.1

火基-功能“：^3.15.6

mkdirp：^1.0.4

uuid：^8.3.2

在扩展上的应用

firebase-管理：^8.0.0

消防基地-功能：^3.13.2

mkdirp：^1.0.4

夏普: 0.23.4

uuidv4：^6.1.0

，这是调整图像大小的代码

请注意这一行：await remoteFile.download({ destination: originalFile }); // <- Offending line of code...，因为这是它失败的行。

const resizeImage = async (object): Promise<ResizedImageResult[]> => {
  logs.start();
  const { contentType } = object; // This is the image MIME type

  const tmpFilePath = path.resolve('/', path.dirname(object.name)); // Absolute path to dirname

  if (!contentType) {
    logs.noContentType();
    return;
  }

  if (!contentType.startsWith('image/')) {
    logs.contentTypeInvalid(contentType);
    return;
  }

  if (object.contentEncoding === 'gzip') {
    logs.gzipContentEncoding();
    return;
  }

  if (!supportedContentTypes.includes(contentType)) {
    logs.unsupportedType(supportedContentTypes, contentType);
    return;
  }

  if (config.includePathList && !startsWithArray(config.includePathList, tmpFilePath)) {
    logs.imageOutsideOfPaths(config.includePathList, tmpFilePath);
    return;
  }

  if (config.excludePathList && startsWithArray(config.excludePathList, tmpFilePath)) {
    logs.imageInsideOfExcludedPaths(config.excludePathList, tmpFilePath);
    return;
  }

  if (object.metadata && object.metadata.resizedImage === 'true') {
    logs.imageAlreadyResized();
    return;
  }

  const bucket = admin.storage().bucket(object.bucket);
  const filePath = object.name; // File path in the bucket.
  const fileDir = path.dirname(filePath);
  const fileExtension = path.extname(filePath);
  const fileNameWithoutExtension = extractFileNameWithoutExtension(filePath, fileExtension);
  const objectMetadata = object;

  let originalFile;
  let remoteFile: File;
  try {
    originalFile = path.join(os.tmpdir(), filePath);
    const tempLocalDir = path.dirname(originalFile);

    // Create the temp directory where the storage file will be downloaded.
    logs.tempDirectoryCreating(tempLocalDir);
    await mkdirp(tempLocalDir);
    logs.tempDirectoryCreated(tempLocalDir);

    // Download file from bucket.
    remoteFile = bucket.file(filePath);
    logs.imageDownloading(filePath);
    logs.imageDownloading(originalFile);
    await remoteFile.download({ destination: originalFile }); // <- Offending line of code...
    logs.imageDownloaded(filePath, originalFile);

    // Get a unique list of image types
    const imageTypes = new Set(config.imageTypes);

    // Convert to a set to remove any duplicate sizes
    const imageSizes = new Set(config.imageSizes);

    const tasks: Promise<ResizedImageResult>[] = [];

    imageTypes.forEach((format) => {
      imageSizes.forEach((size) => {
        tasks.push(
          modifyImage({
            bucket,
            originalFile,
            fileDir,
            fileNameWithoutExtension,
            fileExtension,
            contentType,
            size,
            objectMetadata: objectMetadata,
            format,
          }),
        );
      });
    });

    const results = await Promise.all(tasks);

    const failed = results.some((result) => result.success === false);
    if (failed) {
      logs.failed();
      return;
    } else {
      if (config.deleteOriginalFile === deleteImage.onSuccess) {
        if (remoteFile) {
          try {
            logs.remoteFileDeleting(filePath);
            await remoteFile.delete();
            logs.remoteFileDeleted(filePath);
          } catch (err) {
            logs.info('Catch 1');
            logs.errorDeleting(err);
          }
        }
      }
      logs.complete();
    }
  } catch (err) {
    logs.info('Catch 2');
    logs.error(err);
  } finally {
    if (originalFile) {
      logs.tempOriginalFileDeleting(filePath);
      fs.unlinkSync(originalFile);
      logs.tempOriginalFileDeleted(filePath);
    }
    if (config.deleteOriginalFile === deleteImage.always) {
      // Delete the original file
      if (remoteFile) {
        try {
          logs.remoteFileDeleting(filePath);
          await remoteFile.delete();
          logs.remoteFileDeleted(filePath);
        } catch (err) {
          logs.errorDeleting(err);
        }
      }
    }
  }
};

期望行为

在执行await remoteFile.download({ destination: originalFile });时，应该下载原始文件。此代码与扩展代码完全相同。

实际行为

下列错误已注销：

}

有人注意到这个问题了吗？我不能回到一个早期版本的Firebase，因为有打破的变化。

Answer 1

对于其他遇到此问题的人，我通过在下面的行中将验证设置为false来修正它：await remoteFile.download({ destination: originalFile, validation: false });

当不使用模拟器时，我将添加逻辑来打开验证。另外，确保扩展的所有环境变量都有默认值(请参阅扩展的源代码中的config.ts文件，并查看GCP中函数详细信息页中的变量选项卡)。
