Question

const http = require('http');
const functions = require('firebase-functions');
const agent = new http.Agent({keepAlive: true});

exports.function = functions.https.onRequest((request, response) => {
    req = http.request({
        host: '',
        port: 80,
        path: '',
        method: 'GET',
        agent: agent,
    }, res => {
        let rawData = '';
        res.setEncoding('utf8');
        res.on('data', chunk => { rawData += chunk; });
        res.on('end', () => {
            response.status(200).send(`Data: ${rawData}`);
        });
    });
    req.on('error', e => {
        response.status(500).send(`Error: ${e.message}`);
    });
    req.end();
});

这是Optimizing networking using Cloud Functions中的代码。如何更新它以使用expressJS。

因此，从代码中，我发现诀窍是此行const agent = new http.Agent({keepAlive: true})，然后是请求agent: agent。

我尝试做类似的事情

const server = express()

server.use((req, res, next) => {
    req.agent = new http.Agent({keepAlive: true})
    next()
})

但是没有用。帮助！！！

只需戴上index.js

require('https').globalAgent.keepAlive = true;

如何使用ExpressJS保持Cloud Functions连接的持久性
