过时
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

useFinalURL 特性为 响应 interface contains a boolean stating whether this is the final URL of the response.

This property applies only to ServiceWorkers . In other contexts it will return undefined .

句法

var isfinalURL = Response.useFinalURL;
					

值

A 布尔 indicating whether or not the URL is final rather than a redirect.

范例

Consider a script residing in page index.html :

fetch('/test').then((r) => console.log(r.url))
					

test.html is being controlled by the service worker sw.js :

onfetch = (e) => {
  e.respondWith(fetch('/page2').then((r) => {
    r.usefinalURL = true;
    return r;
  })
}
					

The output will be /page2 和不 /test in index.html , since setting the usefinalURL means that the response's URL is not set to request's URL.
