Python編寫FTP客戶端
之前寫過一篇ftp服務端的文章，這篇介紹一下客戶端吧。在使用虛擬機器的時候，由於虛擬機器工具沒安裝成功，所以我決定用ftp在主機與虛擬機器之間傳送檔案，在虛擬機器上開啟ftp服務，然後把客戶端放在主機上，當然也可以顛倒過來。服務端請參考 python實現ftp伺服器 import ftplib im...
ftp客戶端 學習筆記
檔案傳輸協議 ftp 作為網路共享檔案的傳輸協議，在網路應用軟體中具有廣泛的應用。ftp的目標是提高檔案的共享性和可靠高效地傳送資料。在傳輸檔案時，ftp 客戶端程式先與伺服器建立連線，然後向伺服器傳送命令。伺服器收到命令後給予響應，並執行命令。ftp 協議與作業系統無關，任何作業系統上的程式只要符...
