# Facebook 集成

> 使用 LangChain Python 与 Facebook 文档加载器集成。

> [Messenger](https://en.wikipedia.org/wiki/Messenger_\(software\)) 是一款由 `Meta Platforms` 开发的美国专有即时通讯应用和平台。最初于 2008 年作为 `Facebook Chat` 开发，该公司于 2010 年对其消息服务进行了改造。

本笔记本介绍如何从 [Facebook 聊天记录](https://www.facebook.com/business/help/1646890868956360) 加载数据，并将其转换为可导入到 LangChain 中的格式。

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
# pip install pandas
```

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
from langchain_community.document_loaders import FacebookChatLoader
```

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
loader = FacebookChatLoader("example_data/facebook_chat.json")
```

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
loader.load()
```

```python theme={"theme":{"light":"catppuccin-latte","dark":"catppuccin-mocha"}}
