环境： 运行环境win 10
安装软件：1.Locust
2.Python2.7
实现说明：以下两上.py文件模拟实现了一个接收请求的server端一个发送请求的client端，都是本机运行

运行方法：
1.启动一个dos窗口，进入存放TcpSocketServer.py 程序的目录下，使用命令：D:\Python2.7\python.exe TcpSocketServer.py 运行Server端程序，如以下图显示为启动成功
2.再启动一个dos窗口，进入存入程序的目录下，使用命令：locust -f D:/Python2.7/Scripts/locust_tcp/TcpSocketLocust.py --csv=test --no-web -c10 -r10 -t2，如以下图显示为请求发送成功，并生成了以test开头的测试报告
