刚开始学习 appium 时，思寒老师已经布置了 appium 启动应用 log 分析的作业。由于工作比较忙，再者自己想先动手用 appium 写个公司的 app 的 UI 测试（目前简单的框架基本完成，在不断完善用例管理中）。写这篇文章是为了完成课堂作业，也为了让自己理清楚 appium 的运行原理。
启动 REST http 服务器，默认监听本地 4723 端口
这里可通过 ip 配置 appium server 的地址) 用于接收客户端（Test Case+Selenium/Appium Driver) 发送的 JSON 格式的 POST 请求
[Appium] Welcome to Appium v1.7.2
[Appium] Appium REST http interface listener started on 0.0.0.0:4723
脚本将 desiredCapabilities 参数 通过 post 请求发送到 Appium 服务器
[HTTP] --> POST /wd/hub/session {"desiredCapabilities":{"appActivity":"com.****.MainActivity","appPackage":"com.****.d","deviceName":"192.168.96.101:5555 ","platformName":"Android","platformVersion":"6.0","newCommandTimeout":0,"connectHardwareKeyboard":true}}
