リダイレクト

すべてのリクエストを一つのURLにリダイレクト

JavaScript

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

Run Worker in Playground

TypeScript

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

Python

from js import Response

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

Rust

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)
}

一つのドメインから別のドメインへリダイレクトリクエストを行う

JavaScript

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);
  },
};

TypeScript

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;

Python

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)

Rust

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)
}
