在字节导向的流中使用 ReadableByteStreamController 时，以及在使用 ReadableStreamBYOBReader 时，readableByteStreamController.byobRequest 属性提供对 ReadableStreamBYOBRequest 实例的访问，该实例表示当前的读取请求。该对象用于访问为读取请求提供的 ArrayBuffer/TypedArray，并提供用于表示数据已提供的方法。

【When using ReadableByteStreamController in byte-oriented streams, and when using the ReadableStreamBYOBReader, the readableByteStreamController.byobRequest property provides access to a ReadableStreamBYOBRequest instance that represents the current read request. The object is used to gain access to the ArrayBuffer/TypedArray that has been provided for the read request to fill, and provides methods for signaling that the data has been provided.】
