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.
