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()
