今日内容：
    1、socket的通信流程介绍
    2、基于tcp协议通信的套接字程序

# 服务端：
import socket

# 基于TCP协议实现简单套接字通信
# phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#
# phone.bind(('127.0.0.1', 8080))
#
# phone.listen(5)
# print('starting %s:%s' % ("127.0.0.1", 8080))
#
# conn, client_addr = phone.accept()
#
# data = conn.recv(1024)         # 最大接收的字节个数
# print('收到的客户端数据：', data.decode('utf-8'))
# conn.send(data.upper())
#
# conn.close()
# phone.close()


# 加上循环
# 服务器应该满足的特性：1、一直对外提供服务  2、并发的提供服务

# phone = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# phone.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
# phone.bind(('127.0.0.1', 8080))
# phone.listen(5)
# print('starting %s:%s' % ('127.0.0.1', 8080))
#
# 链接循环
# while True:
#     conn, client_addr = phone.accept()
#     print(client_addr)
#     # 通信循环
#     while True:
#         try:
#             data = conn.recv(1024)
#             print('收到的客户端数据：', data.decode('utf-8'))
#             conn.send(data.upper())
#         except Exception:
#             break
#
#     conn.close()
#
# phone.close()


# 远程执行命令
import subprocess

                               stderr=subprocess.PIPE
                               )
        res = obj.stdout.read() + obj.stderr.read()
        print(res)
        conn.send(res)
    except Exception:
        break

    conn.close()

phone.close()
