TypeError: scheduler.do is not a function using blob.uploadStream

Question

二手Package

我正在尝试使用

将 blob 上传到 azure blob 存储

blockBlobClient.uploadStream()

但是，程序包抛出此错误：

TypeError: scheduler.do is not a function
at BlockBlobClient.uploadStream (Clients.js:1954)

我的代码是：

    const blockBlobClient = sourceClient.getBlockBlobClient(blobName);
    const blockSize = 4 * 1024 * 1024; // the block size in the uploaded block blob
    const uploadBlobResponse = await blockBlobClient.uploadStream(file, blockSize, 20, {onProgress: (ev) => console.log(ev)});

我该如何解决这个错误？

您收到此错误的原因是您从浏览器调用 uploadStream 方法，但它仅在 Node.JS 运行时可用。来自代码注释 here:

  /**
   * ONLY AVAILABLE IN NODE.JS RUNTIME.
   *
   * Uploads a Node.js Readable stream into block blob.
   *
   * PERFORMANCE IMPROVEMENT TIPS:
   * * Input stream highWaterMark is better to set a same value with bufferSize
   *    parameter, which will avoid Buffer.concat() operations.
   *
   * @param stream - Node.js Readable stream
   * @param bufferSize - Size of every buffer allocated, also the block size in the uploaded block blob. Default value is 8MB
   * @param maxConcurrency -  Max concurrency indicates the max number of buffers that can be allocated,
   *                                 positive correlation with max uploading concurrency. Default value is 5
   * @param options - Options to Upload Stream to Block Blob operation.
   * @returns Response data for the Blob Upload operation.

当您在基于浏览器的应用程序中使用此 SDK 时，您希望使用的上传方法是 uploadBrowserData or uploadData。
