The clone()
method of the Request
interface creates a copy of the current Request
object.
clone()
throws a TypeError
if the response Body
has already been used. In fact, the main reason clone()
exists is to allow multiple uses of Body
objects (when they are one-use only.)
var newRequest = request.clone();
None.
A Request
object, which is an exact copy of the Request
that clone()
was called on.
In the following snippet, we create a new request using the
constructor (for an image file in the same directory as the script), then clone the request.Request.Request()
var myRequest = new Request('flowers.jpg'); var newRequest = myRequest.clone(); // a copy of the request is now stored in newRequest
