curl - curl FTP访问被拒绝

Question

我正在使用curl php API访问FTP链接。在特定站点上，它给出错误代码9（拒绝访问）。但是，可以从IE和Firefox访问该链接。

然后，我运行curl命令行，它给出了相同的“访问拒绝”结果。

> d:>\curl -v ftp://ftp1.example.com/outgoing/EHF/dbex10win_en.zip
> * About to connect() to ftp1.example.com port 21 (#0)
> *   Trying 204.50.113.145...

> * Server denied you to change to the given directory
> * Connection #0 to host ftp1.example.com left intact curl: (9) Server denied you to change to the given directory

但是该链接在Firefox中可以正常工作。这里的cUrl有什么问题？谢谢

尝试摆弄curl的选项--ftp-method

   --ftp-method [method]
          (FTP) Control what method curl should use to reach a file on  a
          FTP(S) server. The method argument should be one of the follow‐
          ing alternatives:

          multicwd
                 curl does a single CWD operation for each path  part  in
                 the given URL. For deep hierarchies this means very many
                 commands. This is how RFC 1738 says it should  be  done.
                 This is the default but the slowest behavior.

          nocwd  curl  does  no CWD at all. curl will do SIZE, RETR, STOR
                 etc and give a full path to the  server  for  all  these
                 commands. This is the fastest behavior.

          singlecwd
                 curl  does  one  CWD  with the full target directory and
                 then operates on the file "normally" (like in the multi‐
                 cwd  case).  This  is  somewhat more standards compliant
                 than 'nocwd' but without the full penalty of 'multicwd'.
