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.
