【问题描述】:
我写了一个简单的上传脚本,然后发现下一件事:curl 尝试在 ftp 服务器上执行 PUT:
简化代码:
import pycurl
from os.path import getsize
c = pycurl.Curl()
c.setopt(pycurl.URL, 'ftp://<ftp_name>:21/asus.c')
c.setopt(pycurl.USERPWD, 'username:password')
c.setopt(pycurl.PROXY, '10.0.0.35')
c.setopt(pycurl.PROXYPORT, 3128)
c.setopt(pycurl.VERBOSE, 1)
f = open('asus.c')
c.setopt(pycurl.INFILE, f)
c.setopt(pycurl.INFILESIZE, getsize('asus.c'))
c.setopt(pycurl.HTTPPROXYTUNNEL, 1)
c.setopt(pycurl.UPLOAD, 1)
c.perform()
几个月前几乎相同的代码运行良好,但是:
* About to connect() to proxy <IP> port 3128 (#0)
* Trying <IP>... * connected
* Connected to <IP> (<IP>) port 3128 (#0)
* Establish HTTP proxy tunnel to <ftp_name>:21
* Server auth using Basic with user 'username'
> CONNECT <ftp_name>:21 HTTP/1.1
Host: <ftp_name>:21
User-Agent: PycURL/7.21.6
Proxy-Connection: Keep-Alive
< HTTP/1.0 200 Connection established
<
* Proxy replied OK to CONNECT request
* Server auth using Basic with user 'username'
> PUT /asus.c HTTP/1.1
Authorization: Basic _______________________________
User-Agent: PycURL/7.21.6
Host: <ftp_name>:21
Accept: */*
Content-Length: 2627
Expect: 100-continue
220 ProFTPD 1.3.3 Server (______ FTP Server) [<IP>]
500 PUT not understood

500 HOST: not understood
500 ACCEPT: not understood
500 CONTENT-LENGTH: not understood
500 EXPECT: not understood

当我尝试从 shell 执行此操作时,响应相同:
curl --upload-file "asus.c" --proxy 10.0.0.35:3128 \
--proxytunnel -u username:password ftp://<ftp_name>/asus.c
为什么?我错过了什么?
【问题讨论】:
-
您似乎正在尝试将 HTTP 与 FTP 服务器通信。您的代理是否作为具有这些设置的 FTP 代理工作,例如来自浏览器或已知的 FTP 客户端?
-
是的。 FileZilla 通过这个代理(它是一个配置好的 squid)很好地连接(和上传)。
