README

dsh-web-search

中文 · English

本插件移植自 nicobailon/pi-web-access（MIT），为 DeepSeek Harness 适配：搜索回退链、DuckDuckGo 解析与正文提取逻辑源自该项目，网络层改用 Node 原生 fetch。感谢原作者。

它能做什么

一个插件，补齐 DSH 的联网能力：

  • 🔍 多引擎搜索自动回退 —— 接管内置 web_search 工具：SearXNG → Tavily → Brave → DuckDuckGo 零配置兜底，未配置的自动跳过，一个 key 都不填也能搜
  • 📄 URL 正文提取 —— get_search_content 工具：抓任意网页，HTML 自动转可读纯文本（优先正文区域、剔除脚本样式），JSON 美化输出，二进制内容明确提示
  • 🎚️ 一键切换默认搜索引擎 —— 设置页开关：开 = 用本插件回退链，关 = 委托官方 DeepSeek 搜索
  • 🛠️ 补齐 fetch seam —— 注册搜索 + 抓取双 provider，内置 web_fetch 因此恢复可用
  • ⚙️ 配置全部在设置页 —— 三个密钥（SearXNG / Tavily / Brave）写入 credentials 服务，卡片式管理，无需改配置文件

安装

从 npm 安装（推荐）：

dsh plugin --profile web add dsh-web-search

从源码安装：

git clone https://github.com/haibinwang9/dsh-web-search.git
cd dsh-web-search && dsh plugin --profile web add .

安装后重启 DSH，在 设置 → 插件 → Web access 里配置密钥/开关即可。

配置项

字段凭证名说明
使用本插件作为默认搜索引擎PIWA_SEARCH_ENABLED开 = 回退链；关 = 官方 DeepSeek 搜索
SearXNG 地址SEARXNG_BASE_URL如 https://search.example.com
Tavily API KeyTAVILY_API_KEYhttps://app.tavily.com 申请
Brave API KeyBRAVE_API_KEYhttps://brave.com/search/api/ 申请

取值优先级：环境变量 → harness credentials 服务（也可写 ~/.dsh/.credentials.yaml）。
