Question

我试图使用FTPwalker遍历ftp目录，但我无法连接。

正在使用当前通话：

walker = ftpwalker(server_name="hostname", url="ftp://username:password@hostname")

但是walker.check_state()给出了：

>> walker.check_state()
Find leading...
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.4/site-packages/FTPwalker/runwalker.py", line 100, in check_state
    self.path_not_exit(False)
  File "/usr/lib/python3.4/site-packages/FTPwalker/runwalker.py", line 157, in path_not_exit
    self.m_walker.Process_dispatcher(False)
  File "/usr/lib/python3.4/site-packages/FTPwalker/main_walker.py", line 82, in Process_dispatcher
    leadings = self.find_leading_dirs(self.root)
  File "/usr/lib/python3.4/site-packages/FTPwalker/main_walker.py", line 37, in find_leading_dirs
    files, dirs = self.run_object.find_leading(top)
  File "/usr/lib/python3.4/site-packages/FTPwalker/traverse.py", line 75, in find_leading
    conn = ftplib.FTP(self.server_url)
  File "/usr/lib64/python3.4/ftplib.py", line 118, in __init__
    self.connect(host)
  File "/usr/lib64/python3.4/ftplib.py", line 153, in connect
    source_address=self.source_address)
  File "/usr/lib64/python3.4/socket.py", line 498, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
  File "/usr/lib64/python3.4/socket.py", line 537, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -2] Name or service not known

此处输入的url参数格式是否正确？ Ping hostname有效。

Answer 1

虽然该参数误导性地命名为url，但official example非常清楚地表明该值实际上应该是普通的主机名：

from FTPwalker.runwalker import ftpwalker

walker = ftpwalker("Uniprot", "ftp.uniprot.org")
walker.check_state()

最后，该值转到ftplib.FTP.connect，其中包含“hostname”。

使用FTPwalker连接到FTP资源失败，并且＆＃34;名称或服务未知＆＃34;
