Available in workers

The arrayBuffer() method of the Request interface reads the request body and returns it as a promise that resolves with an ArrayBuffer.

A promise that resolves with an ArrayBuffer.

Exceptions

• TypeError
  • : Thrown for one of the following reasons:
    • The request body is disturbed or locked.
    • There was an error decoding the body content (for example, because the Content-Encoding header is incorrect).

  • : Thrown if there is a problem creating the associated ArrayBuffer (for example, if the data size is too large).

Examples

const myArray = new Uint8Array(10);

const request = new Request("/myEndpoint", {
