This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage 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 specification changes.
The Response()
constructor creates a new Response
object.
Syntax
var myResponse = new Response(body, init);
Parameters
- body Optional
- An object defining a body for the response. This can be one of:
- init Optional
- An options object containing any custom settings that you want to apply to the response. The possible options are:
status
: The status code for the reponse, e.g.,200
.statusText
: The status message associated with the staus code, e.g.,OK
.headers
: Any headers you want to add to your response, contained within aHeaders
object or object literal ofByteString
key/value pairs (see HTTP headers for a reference).
Example
In our Fetch Response example (see Fetch Response live) we create a new Response
object using the constructor, passing it a new Blob
as a body, and an init object containing a custom status
and statusText
:
var myBlob = new Blob(); var init = { "status" : 200 , "statusText" : "SuperSmashingGreat!" }; var myResponse = new Response(myBlob,init);
