这篇文章主要介绍了python socket通信编程实现文件上传代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

写一个file_receive.py和一个file_send.py程序,由file_send.py上传一个文件,file_receive.py接收上传的文件,写到指定的包内

#file_receive.py
import socket,subprocess,os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
sk = socket.socket()
address = ('127.0.0.1',8001)
sk.bind(address)
sk.listen(3)
conn,addr = sk.accept()
fileinfo = conn.recv(1024)
filename,filesize = str(fileinfo,'utf8').split('|')
#filename = str(filename,'utf8')
#filesize = int(str(filesize,'utf8'))
path = os.path.join(BASE_DIR,'file_recv',filename)
f = open(path,'wb')
has_received = 0
while has_received != int(filesize):
  data = conn.recv(1024)
  f.write(data)
  has_received += len(data)

f.close()
print('well done')
sk.close()

#file_send.py
import socket,os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
sk = socket.socket()
address = ('127.0.0.1',8001)
sk.connect(address)
filename = input("please input filename:")
path = os.path.join(BASE_DIR,filename)
filesize = os.stat(path).st_size
fileinfo = '%s|%s'%(filename,str(filesize))
sk.sendall(bytes(fileinfo,'utf8'))

f = open(path,'rb')

has_sent = 0
while has_sent != int(filesize):
  data = f.read(1024)
  sk.sendall(data)
  has_sent += len(data)

print('well done!')
f.close()
sk.close()

文件运行后,实现了将file_send.py上传的test.png文件上传到当前路径下的file_recv包内.
