Response: url property

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.

Value

A string.

Examples

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 Response.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.

const myImage = document.querySelector("img");

const myRequest = new Request("flowers.jpg");

fetch(myRequest)
  .then((response) => {
    console.log("response.url =", response.url); // response.url = https://mdn.github.io/dom-examples/fetch/fetch-response/flowers.jpg
    return response.blob();
  })
  .then((myBlob) => {
    const objectURL = URL.createObjectURL(myBlob);
    myImage.src = objectURL;
  });
