node.js - nginx 在每秒请求时变慢

Question

我目前正在为我的网站创建一个 api，使用 nodejs 和 nginx，我已经为我将要运行的每个 nodejs 应用程序设置反向代理(api、mainsite、其他东西..)。

但是，当我尝试我的 api 时，它会在每次请求时使用很长时间，有时会超时。

知道有什么问题吗？这种情况已经有一段时间了，我快要死了:(

请帮忙，它毁了我开发应用程序的时间:/

添加这个是因为这对我有用

https://forum.nginx.org/read.php?15,239760,239760似乎表明您可以将 proxy_pass 传递给 127.0.0.1 而不是 localhost 并且请求顺利通过

One year old but I wanted to point out that there is a work around for that issue. Like Cruz Fernandez wrote you can set 127.0.0.1 instead of localhost on the proxy_pass directive. This prevents the 60s delay on every second request. I'm using Windows 8.1 and nginx 1.9.5.

location /nodejsServer/ {
    proxy_pass http://127.0.0.1:3000/;
