pythonftp

⑴ python ftp模塊有支持passive off這個命令嗎

因為FTP有兩種工作模式，PORT方式和PASV方式，中文意思為主動式和被動式，詳細介紹如下：主動FTP：命令連接：客戶端>1024埠→伺服器21埠數據連接：客戶端>1024埠←伺服器20埠被動FTP：命令連接：客戶端>1024埠→伺服器21埠數據連接：客戶端>1024埠←伺服器>1024埠PORT（主動）方式的連接過程是：客戶端向伺服器的FTP埠（默認是21）發送連接請求，伺服器接受連接，建立一條命令鏈路。當需要傳送數據時，客戶端在命令鏈路上用PORT命令告訴伺服器：「我打開了***X埠，你過來連接我」。於是伺服器從20埠向客戶端的***X埠發送連接請求，建立一條數據鏈路來傳送數據。PASV（被動）方式的連接過程是：客戶端向伺服器的FTP埠（默認是21）發送連接請求，伺服器接受連接，建立一條命令鏈路。當需要傳送數據時，伺服器在命令鏈路上用PASV命令告訴客戶端：「我打開了***X埠，你過來連接我」。於是客戶端向伺服器的***X埠發送連接請求，建立一條數據鏈路來傳送數據。解決此問題的法也很簡單，關閉客戶端的PASV方式，強制其用PORT方式訪問伺服器，登錄FTP伺服器後用passive命令關閉客戶端的PASV方式，如下：ftp>passivePassivemodeoff.ftp>passive(再次運行命令可打開）Passivemodeon.

⑶ python ftp連接指定伺服器，並下載指定文件

ftp客戶端一般只有顯示、上傳、下載，並沒有打開文件的操作，所以你得先下載相應配置文件，在本地解析後，再繼續用相關參數下載後續文件。

⑷ python，如何下載FTP上的文件

importftplib,socket
defconnect():
CONST_HOST="xxxx.xxxx.xxx"
CONST_USERNAME="xxxxx"
CONST_PWD="xxxxxxx"
try:
ftp=ftplib.FTP(CONST_HOST)
ftp.login(CONST_USERNAME,CONST_PWD)
returnftp
exceptsocket.error,socket.gaierror:
print("FTPisunavailable,pleasecheckthehost,usernameandpassword!")
sys.exit(0)

defdisconnect(ftp):
ftp.quit()

defdownload(ftp,filename):
#預定義每次寫文件的buffer
CONST_BUFFER_SIZE=8192
f=open(filename,"wb").write
try:
ftp.retrbinary("RETR%s"%filename,f,CONST_BUFFER_SIZE)
exceptftplib.error_perm:
returnFalse
returnTrue

deffind(ftp,filename):
ftp_f_list=ftp.nlst()
iffilenameinftp_f_list:
returnTrue
else:
returnFalse
ftp=connect()
#yourfile為你想要下載的文件
iffind(ftp,'yourfile'):
download(ftp,'yourfile')
disconnect(ftp)

⑸ Python中如何獲取FTP伺服器上的文件大小

這要看你下載用了哪個ftp庫
搜到的代碼

files = ftp.nlst()
for f in files:
print f

⑺ 如何在Python中使用FTP

from ftplip import FTP # 首先要引入 ftplib 這個庫

# 接著，這是我自定義的幾個用於操作 ftp 的函數，def 後面跟的是自定義函數名，函數體內FTP 相關的語句和函數來自上面 import 那個包，你自己體會吧：
# 初始化 FTP 連接
def ftp_open(HOST,PORT,USERNAME,PASSWORD):
ftp=FTP()
ftp.set_debuglevel(2)
ftp.connect(host=HOST,port=PORT)
ftp.login(USERNAME,PASSWORD)
return ftp

# 關閉 FTP 連接
def ftp_close(ftp):
ftp.set_debuglevel(0)
ftp.quit()

# 文件上傳函數，filename 可以是windows 格式包含全路徑的文件
def ftp_up(ftp,filename):
#print(ftp.getwelcome())
#ftp.cwd('xxx/www')
file_handler=open(filename,'rb')
ftp.storbinary('STOR %s' % os.path.basename(filename),file_handler)
file_handler.close()
print('FTP up OK.')

# 文件下載函數，filename 可以是windows 格式包含全路徑的文件
def ftp_down(ftp,filename):
#print(ftp.getwelcome())
#ftp.cwd('xxx/www')
file_handler=open(filename,'wb')
ftp.retrbinary('RETR %s' % os.path.basename(filename),file_handler)
file_handler.close()
print('FTP down OK.')

⑻ python如何創建FTP目錄

直接使用ftplib就可以實現，其中有一個nlst功能用於查詢目錄，cwd用於改變目錄，還有一個size功能。你這邊只需要保留一個目錄的鏡像。如果發現有目錄差異，或者是文件大小發生變更，就用retrbinary進行文件同步就可以。

⑼ python ftp permission denied怎麼解決

FTP 550 Permission denied 只能建文件夾，沒法刪除及上傳文件的解決方法，需要的朋友可以參考下。

出現這種問題，
①首先檢查用戶對應的角色名，然後看路徑設置是否正確，有沒有相關的許可權，如果這些都沒問題，然後就嘗試下面的操作：
②重起FTP服務，最好從服務裡面重啟(不能根本解決)；
③重新設置Server-U帳號和目錄訪問里的文件路徑(如果還不行，嘗試下面操作)；
④刪除用戶，重新建。
