Nginx无法满足node.js POST请求 [英] Nginx unable to serve the node.js POST requests

问题描述

我有一台VM Ubuntu15.04服务器，并且已将nginx配置为侦听端口80上的请求，并将请求转发到不同端口上的相应应用程序.我有一个运行在端口3000上的简单的node.js服务，该服务具有一个GET和POST服务.我已经通过使用PM2启动了它，并在我的nginx默认conf中将proxy_pass添加到localhost:3000/中.问题是，当我尝试使用GET请求时，它工作正常，但在POST的情况下，它显示404错误.我试图通过邮递员客户端使用POST服务.

I've a VM Ubuntu15.04 server and I've configured nginx to listen requests on port 80 and forward them to respective applications on different ports. I have a simple node.js service running over port 3000 which has one GET and POST service. I have started it by using PM2 and added a proxy_pass to localhost:3000/ in my nginx default conf. The problem is when i try to use a GET request it is working fine but in case of POST it is showing 404 error. I've tried to use the POST service through postman client.

这是我的默认nginx conf文件

This is my default conf file of nginx

推荐答案

在同一location块中使用try_files和proxy_pass可能无法正常工作.

Using try_files and proxy_pass in the same location block is probably not going to work.

如果要nginx测试是否存在静态文件并代理其他所有文件，请使用命名位置:

If you want nginx to test for the presence of a static file and proxy everything else, use a named location:

root /path/to/root;
location / {
    try_files $uri $uri/ @proxy;
}
location @proxy {
    proxy_pass ...;
    ...
}

使用nginx -t测试配置，因为您的问题似乎缺少结束}.

Test the configuration using nginx -t as your question appears to be missing a closing }.
