# Nginx路径兼容配置 - 支持 /api/socket.io 和 /socket.io
# 将此配置添加到你的现有Nginx配置中

# 方法1: 使用正则表达式匹配多种socket.io路径
location ~ ^/(api/)?socket\.io/ {
    # 统一转发到后端的标准路径
    proxy_pass http://localhost:5001/api/socket.io/;
    
    proxy_http_version 1.1;
    
    # WebSocket握手头
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    
    # 其他头
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    
    proxy_read_timeout 86400s;
    proxy_send_timeout 86400s;
    
    # 缓冲区设置
    proxy_buffering off;
    proxy_buffer_size 16k;
    proxy_buffers 4 32k;
}

# 方法2: 分别处理两种路径（如果方法1不工作）
# location = /api/socket.io/ {
#     proxy_pass http://localhost:5001/api/socket.io/;
#     # ... 其他配置保持不变
# }
# 
# location = /socket.io/ {
#     proxy_pass http://localhost:5001/api/socket.io/;
#     # ... 其他配置保持不变  
# }
