I have an Nginx server which works as a proxy server.
I also have 3 different NodeJS Express servers running on ports 8080, 9090 and 8888 (all working correctly).
Servers 8080 and 9090 execute the same APP. Server on 8888 currently should return 'POSTING' when the POST request has been forwarded.
Both GET and POST routes are set up correctly for server 8888 and I get a correct response if I call them directly with CURL requests:
import Express from 'express';
import BodyParser from 'body-parser';
// Initialise server
const server = Express();
// for parsing application/json
server.use(BodyParser.json());
// Setting port
server.set('port', 8888);
server.post('/', function(request, response) {
console.log('POSTING');
response.send('POSTING');
});
server.get('/', function(request, response) {
console.log('GETTING');
response.send('GETTING');
});
console.log(`Starting server on port ${server.get('port')}`)
server.listen(server.get('port'));
My Nginx config is the following:
upstream amit4got {
server 127.0.0.1:8080;
server 127.0.0.1:9090;
}
server {
listen 7070;
server_name 127.0.0.1;
access_log /usr/local/etc/nginx/logs/default.access.log;
error_log /usr/local/etc/nginx/logs/default.error.log;
location /amit4got/ {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_pass http://amit4got;
proxy_read_timeout 90;
}
location /amit4got/flows {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_read_timeout 90;
if ($request_method = POST) {
proxy_pass http://127.0.0.1:8888;
}
if ($request_method = GET) {
proxy_pass http://amit4got;
}
}
}
Nginx serves on port 7070, and for the endpoint /amit4got loads the content from either 8080 or 9090.
The problem is that when I try to POST to /amit4got/flows, there is no POST request to http://127.0.0.1:8888. I just get a response of 404 not found.
If I change the proxy_pass to a rewrite, then I get a correct response from the 8888 server.
if ($request_method = POST) {
rewrite ^ http://127.0.0.1:8888;
}
I need to send through the POST params, so the rewrite does not work for me.
How can I make the proxy_pass to server 8888 work?
Thanks, Amit
