Cors for GET with Postman not showing headers

fixed the issue. Will look into that further The answer is the Origin header. The Spring MVC framework responds with access control headers when it receives a Origin header. Postman does not include a Origin header in a GET request.

Rack-cors not showing headers in production env for swagger-ui_rails

help you fix your problem The Swagger-docs gem that I'm using puts the .json files that I've created into Rails' /public directory. As such, Rails sees this as static files and not something that should go through Rack middleware. Since our production.rb file had config.serve_static_assets = false, that meant that all these static files were the responsibility of our web server (Apache/Nginx) and not the responsibility of rack-cors gem.
After adding in some CORS headers to Apache, swagger-ui loaded appropriately, but was doubling up the headers - 1st for Apache, 2nd for rack-cors.
SetEnvIf Origin ^(https?://.+\.example\.com(?::\d{1,5})?)$   CORS_ALLOW_ORIGIN=$1
Header append Access-Control-Allow-Origin  %{CORS_ALLOW_ORIGIN}e   env=CORS_ALLOW_ORIGIN
Header merge  Vary "Origin"
Header set "Access-Control-Allow-Methods" "GET, POST, OPTIONS"

django-cors-headers and nginx config: preflight response missing CORS headers

this will help I use django-cors-headers 3.1.1 for handling the requests and responses between my Django-backend and Javascript-frontend apps. Transport is non-secured (i.e. http, not https). , I managed to solve this issue by changing 3 things:
    accessKeyId: this.awsAccessKey,
    secretAccessKey: this.awsSecretAccessKey,
    method: 'put',
    url: `${this.backendUrl}/api/assets/`,
    data: formData,
    body: JSON.stringify(formData),
    service: 'ec2',
    region: 'eu-central-1',
    path: '/',
    headers: {
      'Content-Type': 'application/octet-stream'
server {
    listen 80;
    server_name [HOST_IP];

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/ubuntu/[path_to_app]/app.sock;

        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Methods' 'GET, PUT, OPTIONS, POST, DELETE';
            add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,X-Amz-Date';
            add_header 'Access-Control-Max-Age' 86400;
            add_header 'Content-Type' 'text/html; charset=utf-8';
            add_header 'Content-Length' 0;
            return 204;
        if ($request_method = 'PUT') {
            add_header 'Access-Control-Allow-Methods' 'GET, PUT, OPTIONS, POST, DELETE';
            add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,X-Amz-Date';
            add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';
        if ($request_method = 'GET') {
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Methods' 'GET, PUT, OPTIONS, POST, DELETE';
            add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range,Authorization,X-Amz-Date';
            add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';

    location /static/ {
        autoindex on;
        alias /home/ubuntu/analizy/be/site/static/;
from corsheaders.defaults import default_headers
