This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
The url read-only property of the Response interface contains the URL of the response.
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 http://mdn.github.io/fetch-examples/fetch-response/flowers.jpg
response.blob().then(function(myBlob) {
var objectURL = URL.createObjectURL(myBlob);
myImage.src = objectURL;
});
});
