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;
