根据不同的HTTP路由，响应对应内容。

示例代码

addEventListener("fetch", (event) => {
    event.respondWith(
        handleRequest(event.request).catch(
            (err) => new Response(err.stack, { status: 500 })
        )
    );
});

async function handleRequest(request) {
    const { pathname } = new URL(request.url);

    if (pathname.startsWith("/api")) {
        return new Response(JSON.stringify({ pathname }), {
            headers: { "Content-Type": "application/json" },
        });
    }

    if (pathname.startsWith("/status")) {
        const httpStatusCode = Number(pathname.split("/")[2]);

        return Number.isInteger(httpStatusCode)
            ? fetch("https://http.cat/" + httpStatusCode)
            : new Response("That's not a valid HTTP status code.");
    }

    return new Response("This is a http router example!");
}
