python之socket运用之传输大文件详解编程语言

socket建议最大的传输单元是8192个字符，但是如果超过8192就会出现问题，我们可以用下面的方法处理

客户端代码

import subprocess 

import socket 

ip_bind = ("127.0.0.1",9000) 

client = socket.socket() 

client.connect(ip_bind) 

l1 = [] 

while True: 

 option = input("client:") 

 client.sendall(bytes(option,encoding="utf-8")) 

 server_data_size = client.recv(50) 

 print(server_data_size) 

 a = str(server_data_size,encoding="utf-8").strip() 

 print(a) 

 l1 = a.split(":") 

 print(l1) 

 if l1[0] == "server_data_size": 

 client_size_tmp = l1[1] 

 print(client_size_tmp) 

 client_size = int(client_size_tmp) 

 print(type(client_size)) 

 client.send(bytes("ok",encoding="utf-8")) 

 receive_size = 0 

 res = "" 

 while receive_size client_size: 

 server_data = client.recv(100) 

 receive_size += len(server_data) 

 res += str(server_data) 

 else: 

 print(res) 

 print("-------reveive down---------") 

服务端代码

import subprocess 

import socket 

ip_bind = ("127.0.0.1",9000) 

server = socket.socket() 

server.bind(ip_bind) 

server.listen(1) 

print("server is waiting........") 

conn,add = server.accept() 

print("server is connected client") 

while True: 

 client_data = conn.recv(50) 

 a = subprocess.Popen(str(client_data,encoding="utf-8"),stdout=subprocess.PIPE) 

 b = a.stdout.read() 

 server_data_size = "server_data_size:" + str(len(b)) 

 conn.sendall(bytes(server_data_size,encoding="utf-8")) 

 client_ack = conn.recv(10) 

 if str(client_ack,encoding="utf-8") == "ok": 

 conn.sendall(b)
