The headers read-only property of the Response interface contains the Headers object associated with the response.
A Headers object.
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 headers to the console.
const myImage = document.querySelector("img");
const myRequest = new Request("flowers.jpg");
fetch(myRequest)
.then((response) => {
console.log("response.headers =", response.headers);
return response.blob();
})
.then((myBlob) => {
const objectURL = URL.createObjectURL(myBlob);
myImage.src = objectURL;
});
