[nginx] CORS配置多域名详解程序员

access_log /var/log/nginx/www.your.com_access.log; error_log /var/log/nginx/www.your.com_error.log; set $cors_origin ""; if ( $http_origin ~ https?://.*.(a|b).com ) { set $cors_origin $http_origin; add_header Access-Control-Allow-Origin $cors_origin;

curl测试跨域是否生效，a.jpg要存在，查看Access-Control-Allow-Origin字段。

[[email protected] /usr/local/nginx/conf/conf.d]# curl -I -H "Origin: https://test.a.com" https://www.your.com/a.jpg
