Blob 接口的 stream() 方法返回 ReadableStream which upon reading returns the data contained within the Blob .

句法

var stream = blob.stream();
					

参数

None.

返回

A ReadableStream which, upon reading, returns the contents of the Blob .

用法注意事项

采用 stream() and the returned ReadableStream , you gain several interesting capabilities:

• 调用 getReader() on the returned stream to get an object to use to read the data from the blob using methods such as the ReadableStreamDefaultReader 接口的 read() 方法。
• Call the returned stream's pipeTo() method to pipe the blob's data to a writable stream.
• Call the returned stream's tee() 方法到 tee the readable stream. This returns an array containing two new ReadableStream objects, each of which returns the contents of the Blob .
• Call the returned stream's pipeThrough() method to pipe the stream through a TransformStream or any other readable and writable pair.
