JavaScript Runtime APIs - Request

The Request interface represents an HTTP request and integrates the Fetch API.

How it works

The Request object can be built and also seen as the property of a fetchevent received by edge function.

  addEventListener("fetch", event => {
    const request = event.request
    const url = "https://example.com"

    const myRequest = new Request(url, {
      body: request.body,
      headers: request.headers,
      method: request.method,
      redirect: request.redirect
    })
  })

  addEventListener("fetch", event => {
  let request = event.request
  })

Constructor

  let request = new Request(input [, init])

Parameters

Input: string | Request - defines the resource you want to search for by using a URL or Request object.

bodyUsed - stores a Boolean that declares whether the request body has already been used in a response.

redirect - contains the redirection mode to use: follow, error, or manual.
