【BIGTREETECH CB1核心板＆PI4B试用】第七篇 Python TCP通信 [复制链接]

准备搞一搞TCP网络通信

TCP的python学习参考python核心编程和python网络编程两本书

有了这两个基础，基本python的TCP简单应用也不在话下了

编写了一个bigtreetcp.py(SERVER) 一个computer.py

一新建py文件

新建一个bigtreetcp.py文件

二PC电脑创建一个coputertcp.py文件

使用pycharm

三运行py文件

PC机上运行

输入数据测试

通信成功

电脑端的代码

import socket
import time
import sys

SERVER_IP = "192.168.43.17"  # 树莓派的IP地址
SERVER_PORT = 8888

print("Starting socket: TCP...")
server_addr = (SERVER_IP, SERVER_PORT)
socket_tcp = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

while True:
    try:
        print("Connecting to server @ %s:%d..." % (SERVER_IP, SERVER_PORT))
        socket_tcp.connect(server_addr)
        break
    except Exception:
        print("Can't connect to server,try it latter!")
        time.sleep(1)
        continue
print("Please input:")
while True:
    try:
        data = socket_tcp.recv(512)
        if len(data) > 0:
            print("Received: %s" % data)
            command = input()
            socket_tcp.send(command.encode())
            time.sleep(1)
            continue
    except Exception:
        socket_tcp.close()
        socket_tcp = None
        sys.exit(1)

MCU端的代码

#coding:utf-8
#import necessary package
import socket
import time
import sys
 
 
HOST_IP = "192.168.43.17" #树莓派的IP地址
HOST_PORT = 8888
print("Starting socket: TCP...")
#1.create socket object:socket=socket.socket(family,type)
socket_tcp = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print("TCP server listen @ %s:%d!" %(HOST_IP, HOST_PORT) )
host_addr = (HOST_IP, HOST_PORT)
#2.bind socket to addr:socket.bind(address)
socket_tcp.bind(host_addr)
#3.listen connection request:socket.listen(backlog)
socket_tcp.listen(1)
#4.waite for client:connection,address=socket.accept()
socket_con, (client_ip, client_port) = socket_tcp.accept()
print("Connection accepted from %s." %client_ip)
str='hello python tcp server'
str=str.encode()
socket_con.send(str)
 
print("Receiving package...")
 
###主循环
while True:
 try:
  data=socket_con.recv(512)
  if len(data)>0:
   print("Received:%s"%data)
   socket_con.send(data)
   time.sleep(1)
   continue
 except Exception:
   socket_tcp.close()
   sys.exit(1)
