[英]ftp_login authentication fails
I have something set up like this (only the names have changed): 我有这样的设置(仅名称已更改):
$connection = ftp_connect('hostname.com') or die('Connection failure');
$login_result = ftp_login($connection, 'username', 'password');
This outputs the error: 输出错误:
ftp_login(): Authentication failed. in /path/to/file.php
Copy-pasting from my PHP into an FTP client like Cyberduck succeeds. 从我的PHP复制粘贴到Cyberyuck等FTP客户端成功。 The resource
$connection
seems to exist because otherwise it should die before the ftp_login
line. 资源
$connection
似乎存在,因为否则它应该在ftp_login
行之前ftp_login
。 I'm 100% sure that I have the correct username and password (as evidenced by the Cyberduck test). 我100%确保我具有正确的用户名和密码(如Cyberduck测试所证明的)。
The only thing that throws alarm bells in my head is that I know PHP handles strings differently when there's an @
symbol at the front, and my password may or may not have one or more symbols in it. 唯一让我警惕的是,我知道PHP的前面有一个
@
符号时,对字符串的处理方式有所不同,并且我的密码中可能有也可能没有一个或多个符号。
EDIT: 编辑:
Since Cyberduck is on my work machine and PHP is running on AWS, I decided to run two tests to narrow down the possibilities. 由于Cyberduck在我的工作计算机上并且PHP在AWS上运行,因此我决定运行两个测试以缩小可能性。 I set up an SSH tunnel:
我设置了SSH隧道:
ssh -L 11111:foo.com:21 adam@foo.com
And ran Cyberduck on adam@localhost:11111
, getting this error message in console: 然后在
adam@localhost:11111
上运行Cyberduck,在控制台中得到以下错误消息:
channel 3: open failed: connect failed: Connection refused
Inconclusive results to me. 对我来说没有定论的结果。
So I brought over the 2 lines of PHP script to my machine, and got Authentication failed
again. 因此,我将两行PHP脚本带到了我的机器上,并再次使
Authentication failed
。 So it looks like a PHP problem... 所以它看起来像一个PHP问题...
It turns out that the problem was the password. 原来,问题出在密码。 I don't know why it's an issue, but having an ampersand (
&
) as the first character of the password was throwing things off. 我不知道为什么这是一个问题,不过话说符号(
&
)作为密码的第一个字符被扔东西了。 Changing the password to something that didn't have a leading ampersand worked. 将密码更改为没有前导号的字符可以正常工作。
