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），h5（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
