async function createBlobFromLocalPath( containerClient: ContainerClient, blobName: string, uploadFile:Blob, uploadOptions: BlockBlobParallelUploadOptions ): Promise<void> { // create blob client from container client const blockBlobClient = await containerClient.getBlockBlobClient(`${blobName}/${uploadFile.name}`); // upload file to blob storage const uploadResult = await blockBlobClient.uploadStream( uploadFile, {} ); console.log(uploadResult) if (!uploadResult.errorCode) { console.log(`${blobName} succeeded ${uploadResult.date}`); return } console.log(uploadResult) } 提示类型“Blob”的参数不能赋给类型“Readable”的参数。 类型“Blob”缺少类型“Readable”的以下属性: readableAborted, readable, readableDidRead, readableEncoding 及其他 37 项。

这段代码中的问题是，`uploadFile` 参数的类型为 `Blob`，但是 `uploadStream` 方法需要传入一个 `Readable` 类型的参数。这两个类型并不兼容，因此会出现类型错误。需要将 `uploadFile` 转换为 `Readable` 类型，可以使用 `stream.Readable.from` 方法来实现。修改后的代码如下：

import * as stream from 'stream';

async function createBlobFromLocalPath(
  containerClient: ContainerClient,
  blobName: string,
  uploadFile: Blob,
  uploadOptions: BlockBlobParallelUploadOptions
): Promise<void> {
  // create blob client from container client
  const blockBlobClient = await containerClient.getBlockBlobClient(`${blobName}/${uploadFile.name}`);

  // convert Blob to Readable stream
  const readableStream = stream.Readable.from(uploadFile);

  // upload file to blob storage
  const uploadResult = await blockBlobClient.uploadStream(
    readableStream,
    {},
    uploadOptions
  );

  console.log(uploadResult);

  if (!uploadResult.errorCode) {
    console.log(`${blobName} succeeded ${uploadResult.date}`);
    return;
  }

  console.log(uploadResult);
}
