Tianyi Cui a8cf78630c docs: align zh subsystem pages with late en-side precision edits
The translators' clause-by-clause verification pass caught the English
pages' final wording refinements (tui built-in dialogs enumeration and
display()'s line-feed exception, invariants whitespace-padded/companion
phrasing, client-modules fiber-lifecycle parenthetical, storage strict
sequence, workspace first-successful-start) landing after the initial
zh versions; this aligns the eight pages and re-records their pairs.

# HTTP 服务器
[English](http-server.md) | 中文
[dsh-host-webserver](../../packages/host/webserver) 是 GUI 宿主 web 形态的 HTTP 载体:单个提供 `ctx.httpServer``node:http` 插件,由具名路由注册表加 index.html 转换挂点组成,兜底是静态 dist 回退。它不属于 agent loop智能体循环主干也不是能力 seam它不了解任何 harness 概念,每个功能表面(`/api` 桥接、插件 bundle、HMR热模块替换事件流都是由其他插件注册的一条路由[分层说明](../../.agents/notes/implemented/architecture/2026-07-19-gui-layering-and-rpc-protocol.md))。仅限 web浏览器形态Electron 通过 `file://` 加载 dist并经 IPC 桥接承载 fetch不经过本服务器。
源码:[`packages/host/webserver/src/index.ts`](../../packages/host/webserver/src/index.ts)
## 路由
```ts type-equiv
/** Route match kind: 'exact' matches the pathname verbatim; 'prefix' p matches p and p/<anything>. */
type WebRouteKind = 'exact' | 'prefix'
```
```ts type-equiv
/** One named route registration. */
interface WebRoute {
kind: WebRouteKind
/** Absolute pathname, no trailing slash. */
path: string
/** Owns the full response lifecycle (may hold the response open, e.g. SSE). */
handler: (req: IncomingMessage, res: ServerResponse) => void | Promise<void>
}
```
匹配顺序固定:先查 exact 表,再取最长匹配前缀,最后落到静态 dist 回退。注册顺序不携带任何面向请求的语义:具名路由在组合上互不相交,启动窗口期内尚未被认领的请求全部由回退应答。回退遵循固定语义:非 GET/HEAD 返回 405越出 dist 根目录的遍历返回 403任何未命中都以 HTTP 200 回退到 `index.html`SPA 路由),未知扩展名按 octet-stream 提供([`static.ts`](../../packages/host/webserver/src/static.ts))。
## 配置
```ts type-equiv
/** Gateway config: listen address plus the static dist anchor (injected by the composing app, never self-resolved). */
interface Config {
/** Listen host; the two supported values are loopback and all-interfaces. */
host: '127.0.0.1' | '0.0.0.0'
/** Listen port; zero requests an OS-assigned port. */
port: number
/** Absolute path of index.html inside the static root (dist location is workspace knowledge of the app). */
distIndex: string
}
```
`host` 只接受 `127.0.0.1`(默认姿态)和 `0.0.0.0`(刻意的网络暴露);没有 TLS、认证或 origin 策略,因此绑定到非回环地址会把服务器暴露给该网络。`distIndex` 是组合应用解析后注入的组装事实。
## 服务
`HttpServerService``ctx.httpServer`在激活时立即监听监听失败EADDRINUSE 等)会从 init 抛出,形成一个 FAILED fiber由启动的大声失败 sweep 上报。`register(route)` 添加一条具名路由并返回其 disposer重复的 `(kind, path)` 抛出异常,因为路由模式是组合层契约,冲突即配置错误。`tapIndex(transform)` 添加一个纯的 html 到 html 转换,按注册顺序应用于每个 index 响应(`/` 和每次 SPA 回退);[dsh-client-modules](../../packages/client/modules) 用它注入启动 manifest元数据清单。`port` 读取监听端口,`config.port` 为 0 时读到的是操作系统分配的值。
处理过程中抛出异常的请求(畸形的 % 转义撞上 `decodeURIComponent`、客户端在请求体中途断开)会记录为警告并应答 400响应头已发出时则销毁 socket绝不导致进程退出。dispose资源释放把 `close()` 与 `closeAllConnections()` 配对使用,因为处理器可能像 SSEServer-Sent Events那样保持响应打开而这类连接永远不会自行结束没有强制关闭拆卸就会挂起。该包package从不打印输出URL 行归 shell 所有。逐包运维细节(含开发模式的 bundle 监视流水线)留在 [README](../../packages/host/webserver/README.md) 中。
