Koa JavaScript
一个用于 Koa 的 JavaScript 代码片段,以空 GIF 响应对 /pixel.gif 的请求,GIF 在启动时只解码一次。
Koa JavaScript
import Koa from 'koa';
import Router from '@koa/router';
const GIF = Buffer.from('R0lGODlhAQABAIAAAP///wAAACH5BAEAAAAALAAAAAABAAEAAAICRAEAOw==', 'base64');
const app = new Koa();
const router = new Router();
router.get('/pixel.gif', (ctx) => {
ctx.type = 'image/gif';
ctx.set('Cache-Control', 'no-store');
ctx.body = GIF;
});
app.use(router.routes()).listen(8080);
我们运行了此代码片段,并比对了它返回的字节。
