使用Python开发会聊天的智能小机器人

本文重点演示使用socket实现TCP通信以及字典和集合的用法，客户端发来信息之后，服务端会尽量猜测客户端要表达的真正意思，然后选择合适的内容进行回复。

服务端小机器人代码：

import socket
from os.path import commonprefix
words = {'how are you?':'Fine,thank you.',
         'how old are you?':'38',
         'what is your name?':'Dong FuGuo',
         "what's your name?":'Dong FuGuo',
         'where do you work?':'University',
         'bye':'Bye'}
HOST = ''
PORT = 50007
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#绑定socket
s.bind((HOST, PORT))
#开始监听一个客户端连接
s.listen(1)
print('Listening on port:',PORT)
conn, addr = s.accept()
print('Connected by', addr)
#开始聊天
while True:
    data = conn.recv(1024).decode()
    if not data:
        break
    print('Received message:', data)
    #尽量猜测对方要表达的真正意思
    m = 0
    key = ''
    for k in words.keys():
        #删除多余的空白字符
        data = ' '.join(data.split())
        #与某个“键”非常接近
        #就直接返回
        if len(commonprefix([k, data])) > len(k)*0.7:
            key = k
            break
        #使用选择法
        #选择一个重合度较高的“键”
        length = len(set(data.split())&set(k.split()))
        if length > m:
            m = length
            key = k
    #选择合适的信息进行回复
    conn.sendall(words.get(key, 'Sorry.').encode())
conn.close()
s.close()

客户端代码：

import socket
import sys
#服务端主机IP地址和端口号
HOST = '10.2.1.2'
PORT = 50007
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
    #连接服务器
    s.connect((HOST, PORT))
except Exception as e:
    print('Server not found or not open')
    sys.exit()
while True:
    c = input('Input the content you want to send:')
    #发送数据
    s.sendall(c.encode())
    #从服务端接收数据
    data = s.recv(1024)
    data = data.decode()
    print('Received:', data)
    if c.lower() == 'bye':
        break
#关闭连接
s.close()
