tcp是一种可靠的网络传输协议,python可以实现该通信
服务端代码
from socket import *
server_socket=socket(AF_INET,SOCK_STREAM)
server_socket.bind(("127.0.0.1",8888))
server_socket.listen(5) #监听数量
print("服务器已启动")
client_socket,client_addr=server_socket.accept()
data=client_socket.recv(1024)
print("客户端发送来的数据为:",data.decode('utf-8')) #解码数据
client_socket.send("我是服务端".encode("utf-8")) #向客户端发送数据
server_socket.close()
客户端代码
from socket import *
client_socket=socket()
client_socket.connect(("127.0.0.1",8888))
print("与服务器连接成功")
client_socket.send("我是客户端".encode('utf-8')) #编码
data=client_socket.recv(1024) #接收服务端的数据
print(data.decode("utf-8")) #解码
client_socket.close()
可以通过循环的方式实现多次消息的传递
服务端
#服务端:当输入bye时,结束通信
from socket import *
server_socket=socket(AF_INET,SOCK_STREAM)
server_socket.bind(("127.0.0.1",8888))
server_socket.listen(5)
print("服务器已启动"+"-"*100)
client_socket,client_addr=server_socket.accept()
data=client_socket.recv(1024)
data=data.decode("utf-8")
while data!="bye":
print(data)
data=input("请输入内容:")
if data=="bye":
break
client_socket.send(data.encode("utf-8"))
data=client_socket.recv(1024).decode("utf-8")
client_socket.close()
server_socket.close()
print("服务器结束"+"-"*100)
客户端
#客户端
from socket import *
client_socket=socket()
client_socket.connect(("127.0.0.1",8888))
print("与服务器连接成功"+"-"*100)
data=""
while data!="bye":
data=input("请输入内容")
client_socket.send(data.encode("utf-8"))
if data == "bye":
break
data=client_socket.recv(1024).decode("utf-8")
print(data)
client_socket.close()
文本文件的传输案例
#服务端
from socket import *
server_socket=socket(AF_INET,SOCK_STREAM)
server_socket.bind(("127.0.0.1",8888))
server_socket.listen(5)
print("服务器已启动"+"-"*100)
client_socket,client_addr=server_socket.accept()
print("开始传输文件")
with open("test.CSV",'r',encoding="utf-8") as file:
bytes=file.read(10)
while bytes:
bytes=bytes.encode("utf-8") #编码
client_socket.send(bytes)
bytes=file.read(10)
print("传输结束")
client_socket.close()
server_socket.close()
print("服务器结束"+"-"*100)
#客户端
from socket import *
client_socket=socket()
client_socket.connect(("127.0.0.1",8888))
print("与服务器连接成功"+"-"*100)
with open("test.csv",'w',encoding='utf-8') as file:
data=client_socket.recv(10).decode("utf-8") #解码
while data:
file.write(data)
data=client_socket.recv(10).decode("utf-8")
print("阅读完成")
client_socket.close()
二进制文件的传输案例
