Redirect

Redirect requests from one URL to another or from one set of URLs to another set.

Redirect all requests to one URL

export default {
  async fetch(request) {
    const destinationURL = "https://example.com";
    const statusCode = 301;
    return Response.redirect(destinationURL, statusCode);
  },
};

Run Worker in Playground

export default {
  async fetch(request): Promise<Response> {
    const destinationURL = "https://example.com";
    const statusCode = 301;
    return Response.redirect(destinationURL, statusCode);
  },
} satisfies ExportedHandler;

from js import Response

def on_fetch(request):
    destinationURL = "https://example.com"
    statusCode = 301
    return Response.redirect(destinationURL, statusCode)

use worker::*;

#[event(fetch)]
async fn fetch(_req: Request, _env: Env, _ctx: Context) -> Result<Response> {
    let destination_url = Url::parse("https://example.com")?;
    let status_code = 301;
    Response::redirect_with_status(destination_url, status_code)
}

Redirect requests from one domain to another

export default {
  async fetch(request) {
    const base = "https://example.com";
    const statusCode = 301;

    const url = new URL(request.url);
    const { pathname, search } = url;

    const destinationURL = `${base}${pathname}${search}`;
    console.log(destinationURL);

    return Response.redirect(destinationURL, statusCode);
  },
};

export default {
  async fetch(request): Promise<Response> {
    const base = "https://example.com";
    const statusCode = 301;

    const url = new URL(request.url);
    const { pathname, search } = url;

    const destinationURL = `${base}${pathname}${search}`;
    console.log(destinationURL);

    return Response.redirect(destinationURL, statusCode);
  },
} satisfies ExportedHandler;

from js import Response, URL

async def on_fetch(request):
    base = "https://example.com"
    statusCode = 301

    url = URL.new(request.url)

    destinationURL = f'{base}{url.pathname}{url.search}'
    print(destinationURL)

    return Response.redirect(destinationURL, statusCode)

use worker::*;

#[event(fetch)]
async fn fetch(req: Request, _env: Env, _ctx: Context) -> Result<Response> {
    let mut base = Url::parse("https://example.com")?;
    let status_code = 301;

    let url = req.url()?;

    base.set_path(url.path());
    base.set_query(url.query());

    console_log!("{:?}", base.to_string());

    Response::redirect_with_status(base, status_code)
}
