To solve the issue of Nginx’s cross-origin setting not taking effect, you can try the following methods:<\/p>\n

    \n
  1. Ensure that the CORS-related configurations have been correctly set in the nginx configuration file, such as adding the following content to 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<\/code><\/pre>\n
      \n
    1. To check if the nginx service has reloaded the configuration file, you can use the following command to reload the configuration file:<\/li>\n<\/ol>\n
      sudo nginx -s reload\r\n<\/code><\/pre>\n
        \n
      1. To ensure that the cross-origin settings are effective, check and make sure there is no browser cache interfering. You can try accessing the webpage in cache-free mode or clear the browser cache before revisiting.<\/li>\n
      2. Check the access log and error log of nginx to see if there are any relevant error messages or warnings, troubleshoot and resolve based on the log information.<\/li>\n
      3. If using a reverse proxy server, such as nginx, to proxy to other servers, it may also be necessary to make corresponding cross-origin settings on the server being proxied to.<\/li>\n<\/ol>\n
        If the above methods do not resolve the issue, further examination of nginx configuration and environment may be necessary, or consideration should be given to other factors that may be causing the cross-origin settings to not take effect.<\/p>\n","protected":false},"excerpt":{"rendered":"
