# 按项目阅读

按 externals 源码项目查找扩展包、配置入口与相关主题文档。

已知道项目名或准备部署某个包时，可以直接进入项目页。现有[扩展插件](/framework/externals.md)继续按需求组织：缓存、脚本、调度、表格、云服务和设备集成。项目页把某个实现的部署与限制集中在一起，并链接到完整主题用法。

## 项目索引

以下收录 14 个外部扩展项目；同目录下的 Web、Gateway 和可选存储产物归在相应项目中。

## 如何配合两种目录阅读

如果任务是“导出业务记录”，先从表格主题比较 ClosedXml 与 OpenXml；如果已经选择 ClosedXml，就从项目页检查包、服务匹配和表格命名，再跳转到导出/导入示例。

{% hint style="info" %}
💡 源码目录、NuGet 主包与运行能力不是一一对应的文件。一个项目可能还有独立 Web/Gateway 包，也可能依赖原生库或外部服务；按项目页列出的实际角色选择部署产物。
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zongsoft.com/framework/externals/projects.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
