⑴ 為什麼python socket文件傳輸後的文件打不開
python有三種方法解析XML，分別是SAX，DOM，以及ElementTree: SAX用事件驅動模型，通過在解析XML的過程中
⑵ python中，如何將一個指定的文件發送到對方主機的指定埠呢(用socket方式) 新手求指教！
#發送端
#-*-coding:utf-8-*-
importTkinter
importtkFileDialog
fromsocketimport*
importstruct
importos
defclient(filename):
Addr=('127.0.0.1',8000)
BUFSIZE=2048
Sendsocket=socket(AF_INET,SOCK_STREAM)
Sendsocket.connect(Addr)
FileHead=struct.pack('128s11i',filename,0,0,0,0,0,0,0,0,os.stat(filename).st_size,0,0)
Sendsocket.send(FileHead)
fp=open(filename,'rb')
while1:
FileData=fp.read(BUFSIZE)
ifnotFileData:
break
Sendsocket.send(FileData)
fp.close()
Sendsocket.close()
defFileOpen():
r=tkFileDialog.askopenfilename(title='PythonTkinter',
filetypes=[('Allfiles','*')])
filename=r.split('/')
client(filename[-1])
root=Tkinter.Tk()
button1=Tkinter.Button(root,text='FileOpen',height=8,width=14,bg='blue',
command=FileOpen)
button1.pack()
root.mainloop()#接收端
#-*-coding:utf-8-*-
fromsocketimport*
importos
importstruct
Addr=('127.0.0.1',8000)
BUFSIZE=1024
FileInfoSize=struct.calcsize('128s32sI8s')
SocketRecv=socket(AF_INET,SOCK_STREAM)
SocketRecv.bind(Addr)
SocketRecv.listen(5)
print"waitting........"
conn,addr=SocketRecv.accept()
print"sendfrom",addrFileHead=conn.recv(FileInfoSize)
filename,temp1,filesize,temp2=struct.unpack('128s32sI8s',FileHead)
printfilename,len(filename),type(filename)
printfilesize
filename='new_'+filename.strip(' 0')
fp=open(filename,'wb')
restsize=filesize
while1:
ifrestsize<BUFSIZE:
filedata=conn.recv(restsize)
else:
filedata=conn.recv(BUFSIZE)
ifnotfiledata:
break
fp.write(filedata)
restsize=restsize-len(filedata)
ifrestsize==0:break
fp.close()
conn.close()
SocketRecv.close()
print'Finished!!!'
⑶ python如何使用socket來傳輸對象
importsocket
importstruct
sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
sock.connect(('localhost',10000))
values=(1,'ab',2.7)
packer=struct.Struct('I2sf')
packed_data=packer.pack(*values)
try:
sock.sendall(packed_data)
finally:
sock.close()
有個模塊叫struct，可以自定義結構體，可以這樣發送代碼。
try:
importcPickleaspickle
except:
importpickle
classAA():
defa(self):
print"123"
ddd=AA()
data=pickle.mps(ddd)
還有個模塊叫pickle，可以打包任何python對象，打包的結果也可以拿到套接字里發。
