作業(yè)：

1. 客戶端和服務(wù)器聊天，可以一直聊天，直到一方發(fā)送’拜拜’。
   然后就可以和下一個(gè)人一直聊

(服務(wù)器)

import socket
server = socket.socket()
server.bind(('10.7.187.72', 8086))
server.listen(1024)
while True:
    conversation, addr = server.accept()
    print('接受到請(qǐng)求!')
    while True:
        recv_data = conversation.recv(1024)
        print('客戶端:', recv_data.decode('utf-8'))
        if recv_data.decode('utf-8') == '拜拜':
            break
        message = input('服務(wù)器:')
        conversation.send(message.encode('utf-8'))
        if message == '拜拜':
            break

(客戶端)

import socket

client = socket.socket()
client.connect(('10.7.187.72', 8086))
while True:
    message = input('客戶端:')
    client.send(message.encode('utf-8'))
    if message == '拜拜':
        break
    recv_data = client.recv(1024)
    print('客戶端:', recv_data.decode('utf-8'))
    if recv_data.decode('utf-8') == '拜拜':
        break

2.客戶端給服務(wù)器發(fā)送請(qǐng)求，請(qǐng)求成功后，
客戶端給服務(wù)發(fā)送‘1’，服務(wù)器就給客戶端發(fā)送一張圖片；
客戶端給服務(wù)發(fā)送‘2’，服務(wù)器就給客戶端返回一個(gè)json文件中的內(nèi)容;
客戶端給服務(wù)發(fā)送‘3’, 服務(wù)器返回’拜拜’,然后斷開(kāi)連接

                conversation.send(content)
                print('客戶端', recv_data.decode('utf-8'))
        elif recv_data.decode('utf-8') == '2':
            with open('./1234.json', 'r', encoding='utf-8') as f1:
                json1 = f1.read()
                print(json1)
                conversation.send(json1.encode('utf-8'))
                print('客戶端','2')
        elif recv_data.decode('utf-8') == '3':
            conversation.send('拜拜'.encode('utf-8'))
            break
