前言：为保证用户数据和设备的安全，Google针对下一代 Android 系统(Android P) 的应用程序，将要求默认使用加密连接，这意味着 Android P 将禁止 App 使用所有未加密的连接，因此运行 Android P 系统的安卓设备无论是接收或者发送流量，未来都不能明码传输，需要使用下一代(Transport Layer Security)传输层安全协议，而 Android Nougat 和 Oreo 则不受影响。
因此在Android P 使用HttpUrlConnection进行http请求会出现以下异常
W/System.err: java.io.IOException: Cleartext HTTP traffic to **** not permitted
使用OKHttp请求则出现
java.net.UnknownServiceException: CLEARTEXT communication ** not permitted by network security policy
