作業(yè)：

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

服務器

import socket

sever = socket.socket()

sever.bind(('10.7.187.123', 9990))

sever.listen(100)
print('開始監(jiān)聽')

while True:
    conversation, addr = sever.accept()

    while True:
        recev_data = conversation.recv(1024)
        print('客戶端:', recev_data.decode('utf-8'))
        if recev_data.decode('utf-8') == '拜拜':
            break
        send_data = input('服務器：')
        conversation.send(send_data.encode('utf-8'))

    conversation.close()

客戶端

import socket

client = socket.socket()

client.connect(('10.7.187.123', 9990))

while True:
    send_data = input('客戶端：')
    client.send(send_data.encode('utf-8'))

    rece_data = client.recv(1024)
    if rece_data.decode('utf-8') == '拜拜':
        break
    print('服務器：', rece_data.decode('utf-8'))

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

服務器

import socket
import json

sever = socket.socket()

sever.bind(('10.7.187.123', 9990))

sever.listen(100)
print('開始監(jiān)聽')


while True:

    conversation , addr = sever.accept()
    print('接收請求', addr)

    while True:
        rec_data = conversation.recv(1024)
        if rec_data.decode('utf-8') == '1':
            with open('image_file/ling.png', 'rb')as f:
                content = f.read()
                conversation.send(content)
        elif rec_data.decode('utf-8') == '2':
            with open('image_file/a.json','r')as f:
                content1 = json.loads(f)
                conversation.send(content1)
        elif rec_data.decode('utf-8') == '3':
            content2 = ('拜拜').encode('utf-8')
            conversation.send(content2)
            break

    conversation.close()

客戶端

import socket

client = socket.socket()

client.connect(('10.7.187.123', 9990))

send_data = input('請輸入命令編號：')
client.send(send_data.encode('utf-8'))

# rec_data1 = client.recv(1024)
# print(rec_data1.decode('utf-8'))


data = bytes()

while True:
    rec_data = client.recv(1024)
    data += rec_data
    if not rec_data:
        break

with open('angle.jpg', 'wb')as f:
    f.write(data)
