python tcp_python实现TCP文件传输

前几天已经讲过了UDP协议下大文件传输的python实现代码，今天再实现TCP协议下大文件传输的python实现代码。

TCP和UDP的实现过程还是比较不一样的。

实现代码：

服务端：

import socket

import time

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

s.bind((127.0.0.1,9999))

s.listen(5)

print(Waiting for connection...)

while True:

sock,addr = s.accept()

print(Accept new connection from %s:%s... % addr)

if count == 0:

data1 = sock.recv(1024)

print(str(data1))

file_total_size = int(data1.decode())

received_size = 0

sock.send(received.encode())

data = sock.recv(1024)

filepath = str(data.decode())

f = open(filepath, wb)

while received_size < file_total_size:

data = sock.recv(1024)

f.write(data)

received_size += len(data)

print(已接收 ,received_size, Byte)

data = sock.recv(1024)

if data == bend:

break

f.close()

s.close()

客户端：

import socket

import os

import time

filename = input(please enter the filename you want to send: )

filesize = str(os.path.getsize(filename))

fname1, fname2 = os.path.split(filename)

client_addr = (127.0.0.1,9999)

f = open(filename,rb)

count = 0

flag = 1

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

#建立连接:

s.connect((127.0.0.1, 9999))

while True:

if count == 0:

s.send(filesize.encode())

start = time.time()

s.recv(1024)

s.send(fname2.encode())

for line in f:

s.send(line)

print(sending...)

s.send(bend)

break

s.close

end = time.time()

print(cost + str(round(end - start, 2)) + s)

客户端：
