一，环境部署
1.创建一个django测试项目
二，文档部署
1.下载安装python对应的SDK
使用命令从Github导入完整项目：git clone https://github.com/GeeTeam/gt3-python-sdk.git
手动下载压缩包文件：https://github.com/GeeTeam/gt3-python-sdk/archive/master.zip
2.参数配置
修改请求参数（可选）
| 名称 | 说明 |
|---|---|
| user_id | 用户标识，若担心用户信息风险，可作预处理(如哈希处理)再提供 |
| client_type | 客户端类型，web（pc浏览器），h6（手机浏览器，包括webview），native（原生app），unknown（未知） |
| ip_address | 客户端请求您服务器的ip地址，unknow表示未知 |
三.代码实现
SDK：utils>geetest.py
