本文執行個體講述了Python使用ftplib實現簡易FTP用戶端的方法。分享給大家供大家參考。具體實現方法如下:
#!/usr/bin/python #-*- coding:utf-8 -*- from ftplib import FTP #載入ftp模組 ftp=FTP() #設定變數 ftp.set_debuglevel(2) #開啟調試層級2,顯示詳細資料 ftp.connect("IP","port") #串連的ftp sever和連接埠 ftp.login("user","password")#串連的使用者名稱,密碼 print ftp.getwelcome() #列印出歡迎資訊 ftp.cmd("xxx/xxx") #更改遠程目錄 bufsize=1024 #設定的緩衝區大小 filename="filename.txt" #需要下載的檔案 file_handle=open(filename,"wb").write#以寫入模式在本地開啟檔案 ftp.retrbinaly("RETR filename.txt",file_handle,bufsize)#接收伺服器上檔案並寫入本地檔案 ftp.set_debuglevel(0) #關閉偵錯模式 ftp.quit #退出ftp ftp.dir() #顯示目錄下檔案資訊 ftp.mkd(pathname) #建立遠程目錄 ftp.pwd() #返回當前所在位置 ftp.rmd(dirname) #刪除遠程目錄 ftp.delete(filename) #刪除遠程檔案 ftp.rename(fromname, toname)#將fromname修改名稱為toname。 ftp.storbinaly("STOR filename.txt",file_handel,bufsize) #上傳目標檔案
一個FTP完整執行個體:
#coding:utf-8 from ctypes import * import os import sys import ftplib class myFtp: ftp = ftplib.FTP() bIsDir = False path = "" def __init__(self, host, port='21'): self.ftp.set_debuglevel(2) #開啟調試層級2,顯示詳細資料 #self.ftp.set_pasv(0) #0主動模式 1 #被動模式 self.ftp.connect( host, port ) def Login(self, user, passwd ): self.ftp.login( user, passwd ) print self.ftp.welcome def DownLoadFile( self, LocalFile, RemoteFile ): file_handler = open( LocalFile, 'wb' ) self.ftp.retrbinary( "RETR %s" %( RemoteFile ), file_handler.write ) file_handler.close() return True def UpLoadFile( self, LocalFile, RemoteFile ): if os.path.isfile( LocalFile ) == False: return False file_handler = open( LocalFile, "rb" ) self.ftp.storbinary( 'STOR %s'%RemoteFile, file_handler, 4096 ) file_handler.close() return True def UpLoadFileTree( self, LocalDir, RemoteDir ): if os.path.isdir( LocalDir ) == False: return False LocalNames = os.listdir( LocalDir ) print RemoteDir self.ftp.cwd( RemoteDir ) for Local in LocalNames: src = os.path.join( LocalDir, Local) if os.path.isdir( src ): self.UpLoadFileTree( src, Local ) else: self.UpLoadFile( src, Local ) self.ftp.cwd( ".." ) return def DownLoadFileTree( self, LocalDir, RemoteDir ): if os.path.isdir( LocalDir ) == False: os.makedirs( LocalDir ) self.ftp.cwd( RemoteDir ) RemoteNames = self.ftp.nlst() for file in RemoteNames: Local = os.path.join( LocalDir, file ) if self.isDir( file ): self.DownLoadFileTree( Local, file ) else: self.DownLoadFile( Local, file ) self.ftp.cwd( ".." ) return def show( self, list ): result = list.lower().split( " " ) if self.path in result and "" in result: self.bIsDir = True def isDir( self, path ): self.bIsDir = False self.path = path #this ues callback function ,that will change bIsDir value self.ftp.retrlines( 'LIST', self.show ) return self.bIsDir def close( self ): self.ftp.quit() ftp = myFtp('********') ftp.Login('*****','*****') #ftp.DownLoadFile('TEST.TXT', 'others\\runtime.log')#ok #ftp.UpLoadFile('runtime.log', 'others\\runtime.log')#ok #ftp.DownLoadFileTree('bcd', 'others\\abc')#ok #ftp.UpLoadFileTree('aaa',"others\\" ) ftp.close()print "ok!"
