示例1: function
return async function (req: express.Request, res: express.Response, next: express.NextFunction) {
const redisKey = Redis.Instance.buildCachedRouteKey(req)
await lock.acquire(redisKey, async (done) => {
const cached = await Redis.Instance.getCachedRoute(req)
// Not cached
if (!cached) {
logger.debug('No cached results for route %s.', req.originalUrl)
const sendSave = res.send.bind(res)
res.send = (body) => {
if (res.statusCode >= 200 && res.statusCode < 400) {
const contentType = res.getHeader('content-type').toString()
Redis.Instance.setCachedRoute(req, body, lifetime, contentType, res.statusCode)
.then(() => done())
.catch(err => {
logger.error('Cannot cache route.', { err })
return done(err)
})
}
return sendSave(body)
}
return next()
}
if (cached.contentType) res.contentType(cached.contentType)
if (cached.statusCode) {
const statusCode = parseInt(cached.statusCode, 10)
if (!isNaN(statusCode)) res.status(statusCode)
}
logger.debug('Use cached result for %s.', req.originalUrl)
res.send(cached.body).end()
return done()
})
}示例2: AsyncLock
import * as AsyncLock from "async-lock";
const lock = new AsyncLock();
lock.acquire("key", (done) => {
done();
}, (err, ret) => { /* ... */ });
lock.acquire("key", (done) => { done(); })
.then(() => { /* ... */ })
.catch(() => { /* ... */ });
lock.acquire("key", () => "stringValue")
// Check returned value's type is inherited properly
.then((str) => str.replace("s", "S"));
lock.acquire("key", async () => "stringValue")
// Check returned value's type is inherited properly
.then((str) => str.replace("s", "S"));
lock.acquire([ "key1", "key2" ], (done) => {
done();
}, (err, ret) => { /* ... */ });
lock.isBusy();
lock.isBusy('key');
const lock2 = new AsyncLock({ timeout : 5000 });
const lock3 = new AsyncLock({ maxPending : 5000 });
const lock4 = new AsyncLock({ Promise: null });
示例3: AsyncLock
/// <reference path="async-lock.d.ts" />
