+## NtChat fastapi完整示例
+
+通过fastapi的swagger在线文档可以很方便的管理NtChat接口
+![vfazT0.jpg](https://s1.ax1x.com/2022/08/29/vfazT0.jpg)
+
+## 安装依赖
+```bash
+pip install -r requirements.txt
+```
+
+## 运行例子
+```bash
+python main.py
+```
+
+## 访问api在线文档
+[http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)
+
+
+## 如何调用 
+
+可以使用requests库去访问接口
+
+/client/create 是创建一个微信的实例，返回guid，标识实例的id, 后面所有的接口都要用到
+
+/client/open   是打开并管理上微信实例
