read() 方法在 ReadableStreamBYOBReader interface returns a promise providing access to the next chunk in the byte stream's internal queue.

句法

var promise = readableStreamBYOBReader.read(view);
					

参数

view

The view to be read into.

返回值

A Promise , which fulfills/rejects with a result depending on the state of the stream. The different possibilities are as follows:

• If a chunk is available, the promise will be fulfilled with an object of the form { value: theChunk, done: false } .
• If the stream becomes closed, the promise will be fulfilled with an object of the form { value: undefined, done: true } .
• If the stream becomes errored, the promise will be rejected with the relevant error.

异常

TypeError

The source object is not a ReadableStreamBYOBReader , the stream has no owner, the view is not an object or has become detached, or the view's length is 0.

范例
