Response.error() - Web APIs 编辑

The error() method of the Response interface returns a new Response object associated with a network error.

Note: This is mainly relevant to ServiceWorkers; the error method is used to return an error if you so wish it. An error response has its type set to error.

Note: An "error" Response never really gets exposed to script: such a response to a fetch() would reject the promise.
