Response.url - Web API 接口参考 编辑

The url read-only property of the Response interface contains the URL of the response. The value of the url property will be the final URL obtained after any redirects. 

Syntax

var myURL = response.url;

Value

A USVString.

Example

In our Fetch Response example (see Fetch Response live) we create a new Request object using the Request() constructor, passing it a JPG path. We then fetch this request using fetch(), extract a blob from the response using Body.blob, create an object URL out of it using URL.createObjectURL, and display this in an <img>.

Note that at the top of the fetch() block we log the response URL to the console.

var myImage = document.querySelector('img');

var myRequest = new Request('flowers.jpg');

fetch(myRequest).then(function(response) {
  console.log(response.url); // returns /wiki/en-US/docs/Web/API/Response/flowers.jpg
  response.blob().then(function(myBlob) {
    var objectURL = URL.createObjectURL(myBlob);
    myImage.src = objectURL;
  });
});
