ctx.request => ctx.fresh和ctx.stale

1.请求(ctx.request)的信息

{
    method: "GET",
    url: "/",
    header: {
        host: "localhost:3000",
        connection: "keep-alive",
        cache-control: "max-age=0",
        upgrade-insecure-requests: "1",
        user-agent: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36",
        accept: "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
        accept-encoding: "gzip, deflate, br",
