I want to cache the js and css files of a single page app with nginx on the clients browser. When i tried the currently commented out block, the specified files had a 404 response. Tried putting the block inside the location / { block and the same error happened. Anyone know how to fix this? Help appreciated.

You get 404 because you are not serving anything add proxy_pass to the front app

I have bunch of location directive in my Nginx config and most of them have same add_header, is there any way that I can introduce variable in nginx or any generator for all this config? specially for location directive.
is there any way to set default for add_header so stop repeating in each location directive?
here is 3 locations out of 50 directive in my config:
location ^~ /example/1/ {
proxy_buffering off;
proxy_pass http://10.10.10.113:8124/geoserver/ws/wms;
add_header Pragma no-cache;
add_header Cache-Control private;
add_header Cache-Control no-cache;
add_header Cache-Control no-store;
add_header Expires -1;
}
location ^~ /example-org {
proxy_buffering off;
proxy_pass http://10.10.10.199:9126/geoserver/wms;
add_header Pragma no-cache;
add_header Cache-Control private;
add_header Cache-Control no-cache;
add_header Cache-Control no-store;
add_header Expires -1;
}
location ^~ /example-org/1 {
proxy_buffering off;
proxy_pass http://10.10.10.199:18124/geoserver/wms;
add_header Pragma no-cache;
add_header Cache-Control private;
add_header Cache-Control no-cache;
add_header Cache-Control no-store;
add_header Expires -1;
}
edit #1 (after Richard Smith comment)
add_header Pragma no-cache;

add_header Cache-Control no-cache;
add_header Cache-Control no-store;

I am a newbie in nginx and CORS and finding it challenging getting this right.
I have rest services hosted on a server which blocks CORS so installed nginx to proxy for rest call. What works:
rest api call (from angular code) to backend server after enabling CORS
rest api call (from chrome) to frontend nginx server which has cors enables
What doesn't work: rest api call (from angular code) to frontend nginx
I think the CORS part work as I do not see that error anymore but angular is getting a null response.
For above scenarios, I have tried using GET and POST methods. Response code is 200 OK even for failed scenario.
Here is the nginx conf:
upstream myserver {
server myserver.com:8443;
}
server {
listen 443 ssl;
listen [::]:443 ssl;
server_name myserver.com;
ssl_certificate /some.crt;
ssl_certificate_key /some.key;
location /rest-service/ {
# Simple requests
if ($request_method ~* "(GET|POST)") {
add_header "Access-Control-Allow-Origin" *;
}
# Preflighted requests
if ($request_method = OPTIONS ) {
add_header "Access-Control-Allow-Origin" *;
add_header "Access-Control-Allow-Methods" "GET, POST, OPTIONS, HEAD";
add_header "Access-Control-Allow-Headers" "Authorization, Origin, X-Requested-With, Content-Type, Accept";
return 200;
}
proxy_pass_header Server;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Scheme $scheme;
proxy_set_header X-NginX-Proxy true;
proxy_connect_timeout 5;
proxy_read_timeout 240;
proxy_intercept_errors on;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass https://myserver/rest-service/;
proxy_ssl_trusted_certificate /some.pem;
proxy_ssl_verify off;
proxy_ssl_session_reuse on;
}
}
Here is the angular/typescript code (running from loaclhost):
ngOnInit() {
let url='https://myserver.com/rest-service/login?login=admin&password=password';
this.http.get(this.url).subscribe((response) => {console.log(response); });
}
I think I figured out the issue and posting it here; hope it helps someone.
Following worked:
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' 'http://localhost:4200' always;
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
add_header 'Access-Control-Allow-Headers' 'Origin,Keep-Alive,User-Agent,Cache-Control,Content-Type,Accept' always;
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain charset=UTF-8';
add_header 'Content-Length' 0;
return 204;
}
if ( $request_method = 'GET' ) {
add_header 'Access-Control-Allow-Origin' 'http://localhost:4200' always;
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
add_header 'Access-Control-Allow-Headers' 'Origin,Keep-Alive,User-Agent,Cache-Control,Content-Type,Accept' always;
add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
}
if ( $request_method = 'POST' ) {
add_header 'Access-Control-Allow-Origin' 'http://localhost:4200' always;
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS' always;
add_header 'Access-Control-Allow-Headers' 'Origin,Keep-Alive,User-Agent,Cache-Control,Content-Type,Accept' always;
add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
}
Below is a pretty standard nginx proxy_pass setup:
server {
listen 80;
server_name ireport.jungdigital.com;
access_log /var/log/nginx/ireport.access.log;
root /var/www/ireport.jungdigital.com/dist;
index index.html index.htm;
location / {
}
location /api/ {
if ($request_method = 'OPTIONS') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' 'GET, PUT, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Reques
add_header 'Access-Control-Max-Age' 1728000;
add_header 'Content-Type' 'text/plain charset=UTF-8';
add_header 'Content-Length' 0;
return 204;
}
if ($request_method = 'POST') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' 'GET, PUT, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Reques
}
if ($request_method = 'PUT') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' 'GET, PUT, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Reques
}
if ($request_method = 'GET') {
add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Credentials' 'true';
add_header 'Access-Control-Allow-Methods' 'GET, PUT, POST, OPTIONS';
add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Reques
}
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-NginX-proxy true;
proxy_set_header Host ireport.somehost.org;
proxy_pass http://ireport_dyndns/api/;
proxy_ssl_session_reuse off;
proxy_redirect off;
}
}
The API that I'm proxying returns response body's that contain error information for 400, 404, and 500 error codes. For example, on a 404, my response body might look like:
{
"errorCode": "TOKEN_NOT_FOUND",
"errorMessages": [
"Could not find a matching authorization token."
]
}
If I perform the request without the proxy, I get the response bodies for the errors.
If I use the nginx proxy, for some reason the response bodies are swallowed by nginx and I can't even see a response at all in my web browser Network tab.
Is there a way to tell Nginx to return response bodies for error codes in a proxy_pass?
I run into same question recently.
And the last anwser is that: add proxy header Upgrade
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
My full config as following:
upstream cloud-api {
server 127.0.0.1:8089;
}
client_max_body_size 20M;
client_header_buffer_size 8k;
large_client_header_buffers 4 16k;
server {
listen 8001;
access_log /data/senseid-cloud-log/senseid-cloud-api-access.log;
error_log /data/senseid-cloud-log/senseid-cloud-api-error.log warn;
location / {
proxy_http_version 1.1;
proxy_set_header Host $http_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_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_read_timeout 300s;
proxy_pass http://cloud-api;
}
}
And you could catch 500/401 .etc error body

Hope to give you some help.
See How to add a response header on nginx when using proxy_pass?
Per Alexey's comment - "browsers need headers to allow access to response body. I guess, you need always flag for add_header"
Since nginx 1.7.5 you can use the keyword always to include headers even in error responses - so you can setup your nginx.conf as follow:
-
server {
server_name .myserver.com
location / {
proxy_pass http://mybackend;
add_header X-Upstream $upstream_addr always;
}
}
Today I move Laravel 5.2 from IIS 8.5 to Ubuntu 16.04 (Nginx 1.10.0 - PHP-FPM 7.0.10), I have same problem. The body response from server are always empty when request from Angular2. But the postman still get body on response.
So that must be problem with request headers.
This config help me solved problem above:
add_header 'Access-Control-Allow-Origin' '*' 'always';
add_header 'Access-Control-Allow-Credentials' 'true' 'always';
add_header 'Access-Control-Allow-Methods' 'GET, POST, DELETE, PUT, OPTIONS, HEAD' 'always';
add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type, X-Requested-With' 'always';
Third parameters for add_header only available in recent nginx version.
The following (simplified) NGINX config results in OPTIONS calls correctly getting the Access-Control-Allow-Origin header headers in return, but GET not:
location / {
if ($request_method = OPTIONS ) {
add_header 'Access-Control-Allow-Origin' '$http_origin' always;
return 204;
}
add_header 'Access-Control-Allow-Origin' '$http_origin' always;
try_files $uri #proxy_to_app;
}
location #proxy_to_app {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}
I've tried every combination in the location block, but nothing works, the only solution I could think of that works is moving the this line into the location #proxy_to_app section:
add_header 'Access-Control-Allow-Origin' '$http_origin' always;
It's like that proxy_to_app block is removing the added headers again.
As Alexey Ten stated, I moved add_header into location #proxy_to_app
