You need the proxy_intercept_errors directive.
The default value of this directive is off. You must turn it on if you want to intercept response from proxied server with status code bigger/equal than 300(of course, 502 included). More details about this directive.
Here is an example configuration file which I've tested.
upstream tomcat502 {
server 10.10.100.131:28889; # There is no such a backend server, so it would return 502
}
server {
listen 10019; # it's up to you
server_name 10.10.100.133;
location /intercept502 {
proxy_intercept_errors on; # the most important directive, make it on;
proxy_pass http://tomcat502/;
error_page 502 = @502; # redefine 502 error page
}
location @502 {
return 502 $request_urin; # you could return anything you want.
}
}
After reloading nginx, use curl to test it.
[root@test133 lunatic]# curl http://10.10.100.133:10019/intercept502
/intercept502
[root@test133 lunatic]# curl http://10.10.100.133:10019/intercept502 -I
HTTP/1.1 502 Bad Gateway
Server: nginx/1.12.1
Date: Wed, 09 Jan 2019 13:48:05 GMT
Content-Type: application/octet-stream
Content-Length: 14
Connection: keep-alive
I have added some explanation up in configuration. Hope it would help.
