# nginx 配置优化 - ShortNovel SSE
|
||
|
||
**文件：** `/etc/nginx/sites-enabled/lifescript.happylifeos.com.conf`
|
||
|
||
**变更内容：**
|
||
在 `location /api/shortNovel/` 块中使用以下配置：
|
||
- `proxy_http_version 1.1;` - 确保 SSE 长连接使用 HTTP/1.1
|
||
- `proxy_buffering off;` - 禁用代理缓冲
|
||
- `chunked_transfer_encoding on;` - 启用分块传输编码
|
||
- `proxy_set_header Connection "keep-alive";` - 保持上游连接
|
||
|
||
**原因：**
|
||
- nginx 默认启用 `proxy_buffering on`，会缓冲后端响应
|
||
- 对于 SSE（Server-Sent Events）长连接，缓冲会导致事件无法立即到达前端
|
||
- 禁用缓冲后，每个事件都能立即转发给客户端，实现真正的流式传输
|
||
|
||
**验证：**
|
||
- nginx 语法检查通过：`nginx -t` → syntax is ok / test is successful
|
||
- nginx 重载成功：worker 进程已更新
|
||
- 使用 `curl -N https://lifescript.happylifeos.com/api/shortNovel/stream` 测试 SSE 流式传输
|
||
|
||
**备份文件：** `/etc/nginx/sites-enabled/lifescript.happylifeos.com.conf.backup.20260721_233252`
|
||
|
||
**管理方式：** 宝塔面板，通过 `/etc/init.d/nginx reload` 重载配置
