問題描述
我正在嘗試使用 FTPlib 從 FTP 服務(wù)器下載文件，但我不斷收到以下錯誤消息.我嘗試了在 SO 上找到的幾種方法，即編輯 etc/host 文件并在本地主機 IP 后添加計算機名稱，但這也不起作用.
I'm trying to download a file from an FTP server using FTPlib but i keep getting the error below. I tried several methods found on SO namely editing the etc/host file and adding the computer name after the local host IP but that doesnt work either.
非常感謝任何幫助.(運行mac，python 3.7，macOS Mojave 10.14.2)
Any help is much appreciated. (running a mac, python 3.7, macOS Mojave 10.14.2)
我正在嘗試運行的代碼:
from ftplib import FTP
ftp = FTP('myftpurl')
錯誤:

推薦答案
ftp = FTP('myftpurl')
不清楚 myftpurl 在您的特定代碼中實際包含什么.
但鑒于它的名稱，我假設(shè)您已經(jīng)嘗試過類似 ftp://example.com 的方法.僅作為 明確記錄 FTP(...) 不需要 URL，而是主機名或 IP，即 FTP('example.com') 而不是 FTP('ftp://example.com').
It is not clear what myftpurl actually contains in your specific code.
But given its name I assume that you've tried something like ftp://example.com. Only, as clearly documented FTP(...) does not expect a URL but instead a hostname or IP, i.e. FTP('example.com') and not FTP('ftp://example.com').
給定一個 URL，就像你可能做的那樣，將導(dǎo)致將該 URL 視為主機名，即查找主機名 ftp://example.com.由于這樣的主機不存在，您會收到錯誤消息.
Given a URL like you probably do will result in treating that URL as hostname, i.e. doing a lookup for the hostname ftp://example.com. Since such a host does not exist you get an error.
