nginx配置

1. 专门处理 WebSocket 请求

location /ws/ {
    proxy_pass http://127.0.0.1:25774;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $connection_upgrade;
    proxy_set_header Host $host;
}

# 2. 专门处理 Agent 的 API 请求
# 注意：如果你的后端程序接口就是 /api 开头，这样转发即可
location /api/ {
    proxy_pass http://127.0.0.1:25774;
    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;
}

# 3. 专门处理前端网页/静态文件
location / {
    # 如果 /api 和 /ws 以外的请求全是网页，则转发到这里
    proxy_pass http://127.0.0.1:25774;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
