使用HTTP 接入Python 收发消息如何实现？（1）

[backcolor=transparent]运行环境准备
用 HTTP 协议发送或者接收消息 ，请完成以下环境准备工作。
[backcolor=transparent]Windows

1. 从 Python 官网（https://www.python.org/downloads/windows/) 下载并安装 Python 2.7。
2. 
   打开 Windows 终端窗口（dos界面)，输入 python 命令，检查 Python 是否安装成功， 如下图所示。
   
   [backcolor=transparent]具体示例程序
   您可以参考以下示例程序测试消息收发功能。
   [backcolor=transparent]1.配置文件
   您需要设置配置文件（user.properties）的相关内容，具体请参考申请 MQ 资源 。[list=1]
