To solve the cross-origin issue of Nginx, you can choose from the following several methods:<\/p>\n

    \n
  1. Add cross-origin related headers in the Nginx configuration file: You can enable cross-origin access by adding the following content in the Nginx configuration file.<\/li>\n<\/ol>\n
    location \/ {\r\n    add_header 'Access-Control-Allow-Origin' '*';\r\n    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';\r\n    add_header 'Access-Control-Allow-Headers' 'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range';\r\n    add_header 'Access-Control-Expose-Headers' 'Content-Length,Content-Range';\r\n    \r\n    if ($request_method = 'OPTIONS') {\r\n        add_header 'Access-Control-Max-Age' 1728000;\r\n        add_header 'Content-Type' 'text\/plain charset=UTF-8';\r\n        add_header 'Content-Length' 0;\r\n        return 204;\r\n    }\r\n}\r\n<\/code><\/pre>\n
      \n
    1. By utilizing Nginx’s proxy feature, you can resolve cross-origin issues when your frontend and backend services are under different domain names. You can proxy the frontend requests to the backend domain to prevent cross-origin problems.<\/li>\n<\/ol>\n
      location \/api\/ {\r\n    proxy_pass http:\/\/backend-server;\r\n}\r\n<\/code><\/pre>\n
        \n
      1. Utilizing Nginx’s reverse proxy feature: If your frontend and backend services are on the same domain but different ports, you can use Nginx’s reverse proxy feature to solve the cross-origin issue. By mapping the frontend requests to the backend ports, it helps in avoiding cross-origin problems.<\/li>\n<\/ol>\n
        location \/ {\r\n    proxy_pass http:\/\/backend-server:8080;\r\n}\r\n<\/code><\/pre>\n
        The methods mentioned above are some common ways to solve Nginx cross-origin issues. Choose the appropriate method according to your actual situation for configuration.<\/p>\n","protected":false},"excerpt":{"rendered":"
