Nginx针对具有单独SSL的两个子域的CORS配置

要为具有单独SSL的两个子域设置CORS配置，需要在Nginx配置文件中添加以下代码示例：

server {
    listen 80;
    server_name subdomain1.example.com;

    location / {
        # CORS configuration
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' 'https://subdomain1.example.com';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Max-Age' 86400;
            add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type';
            add_header 'Content-Length' 0;
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            return 200;
        }

        # Other configuration for subdomain1
    }
}

server {
    listen 443 ssl;
    server_name subdomain1.example.com;

    ssl_certificate /path/to/subdomain1_ssl_certificate.crt;
    ssl_certificate_key /path/to/subdomain1_ssl_certificate.key;

    location / {
        # CORS configuration
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' 'https://subdomain1.example.com';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Max-Age' 86400;
            add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type';
            add_header 'Content-Length' 0;
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            return 200;
        }

        # Other configuration for subdomain1
    }
}

server {
    listen 80;
    server_name subdomain2.example.com;

    location / {
        # CORS configuration
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' 'https://subdomain2.example.com';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Max-Age' 86400;
            add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type';
            add_header 'Content-Length' 0;
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            return 200;
        }

        # Other configuration for subdomain2
    }
}

server {
    listen 443 ssl;
    server_name subdomain2.example.com;

    ssl_certificate /path/to/subdomain2_ssl_certificate.crt;
    ssl_certificate_key /path/to/subdomain2_ssl_certificate.key;

    location / {
        # CORS configuration
        if ($request_method = 'OPTIONS') {
            add_header 'Access-Control-Allow-Origin' 'https://subdomain2.example.com';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Max-Age' 86400;
            add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type';
            add_header 'Content-Length' 0;
            add_header 'Content-Type' 'text/plain charset=UTF-8';
            return 200;
        }

        # Other configuration for subdomain2
    }
}

请确保将subdomain1.example.com和subdomain2.example.com替换为实际的子域名，并将/path/to/subdomain1_ssl_certificate.crt和/path/to/subdomain1_ssl_certificate.key替换为实际的SSL证书文件路径和密钥文件路径。

这段代码将针对每个子域设置CORS配置，并添加了针对OPTIONS请求的处理。如果收到OPTIONS请求，将返回适当的CORS标头并返回HTTP状态码200。您还可以根据需要在每个服务器块中添加其他配置。
