}loggerFunc으로 log를 찍을경우 파일로 쓰기가 가능하다. 무한히 log가 커지지 않도록 주기적으로 삭제하거나, 날짜별로 새로 생성하는 것은 고민 필요, log Level에 따라서 여러 파일로 분기하는 것도 고민 필요
index.ts
import { customLogger, loggerFunc } from './custom-logger';
const limiter = rateLimiter({
windowMs: 6 * 1000,
limit: 5, // Limit each IP to 100 requests per `window`
standardHeaders: "draft-6",
keyGenerator: (c) => {
const ip = c.env.requestIP(c.req.raw).address;
return ip;
}, // Method to generate custom identifiers for clients.
handler: async (c, _, options) => {
// TODO: 이겨서 ip를 저장해 두었다가 1시간 동안 request 블럭시키는 것도 가능할 듯.
// 로그가 안 찍혀서 직접 찍는다.
const { method, path } = c.req
const userAgent = c.req.header('user-agent')
const ip = c.env.requestIP(c.req.raw).address
const datetime = new Date().toLocaleString()
loggerFunc("[rateLim]", datetime, method, path, options.statusCode, ip, userAgent)
// Json으로 응답하자

=== 7/14일 추가===
log 파일을 날짜별로 생성하고, 7일이 지난 log파일은 삭제하는 코드를 만들었다. 간단하게 만들었다. 이 보다 더 간단하게는 힘들 것 같다.
