Express post请求给出ERR_EMPTY_RESPONSE [英] Express post request gives ERR_EMPTY_RESPONSE

问题描述

我正在构建一个node.js和express.js网络应用程序，并且在发送请求超过2分钟后不能正常工作。

发生什么事是在2分钟后我的 express 路由被重新呼叫，然后，再过2分钟（总共4分钟），我在该帖子请求的网络标签中收到此错误：

I'm building a node.js and express.js web app and it doesn't works as expected when a post request takes longer than 2 mins.
What happens is that after 2 mins my express route is re-called and then, after another 2 mins (4 mins in total) I get this error in the network tab for that post request:

net :: ERR_EMPTY_RESPONSE

net::ERR_EMPTY_RESPONSE

我读到 express 的默认超时设置为2分钟，但这仅适用于获取请求...

I read that express has a default timeout set to 2 mins, but that applies only to get requests...

这是我的路由：

const router = express.Router();

router.post('/', authenticate, async (req, res) => {
  console.log('here');
  setTimeout(function() {
    res.status(201).json({success: true});   
  }, 400000);
})

当我发送帖子请求时，它会将这里打印到控制台，然后再次打印<$ c $ 2分钟后，c>这里

It prints here to the console when I make the post request, and then it prints again here after 2 minutes.

这是我的索引

const app = express();

app.use(bodyParser.json({limit: '50mb'}));
const compiler = webpack(webpackConfig);

app.use(webpackMiddleware(compiler, {
  hot: true,
  publicPath: webpackConfig.output.publicPath,
  noInfo: true
}));
app.use(webpackHotMiddleware(compiler));

app.get('/*', (req, res) => {
  res.sendFile(path.join(__dirname, './index.html'));
});

app.listen(3000, () => console.log('Running on localhost:3000'));
app.timeout = 700000;

自面临这个问题以来，已经有2周了，任何想法或解决方案都会帮助我许多。如果我需要提供更多的细节，请让我知道。

There are already 2 weeks since I'm facing this issue and any ideas or solutions would help me a lot. Please let me know if I need to provide more details.
