背景：项目需要测试负载均衡，手动搭建一个http服务器
参考链接：https://blog.csdn.net/ordeder/article/details/22490373
遇到的问题：
1、NameError: name 'file' is not defined
解决方法：我用的是python3.6.4，根据上述链接代码操作，打开文件的方式file()改成open()

2、OSError: [WinError 10048] 通常每个套接字地址(协议/网络地址/端口)只允许使用一次

解决方法：打开任务管理器，杀掉“python.exe”的进程，重新编译，在浏览器输入“http://192.168.85.100:49592/”，就可以看到请求了

3、TypeError: a bytes-like object is required, not 'str'
把string类型的返回值改成bytes类型

4、TypeError: string argument without an encoding
解决方法：把bytes(responsebytes)改成(response,encoding = "utf8")

调试成功后的python代码，欢迎使用
