perl不匹配的标记，问题=XML:：Simple模块？

当我尝试运行此脚本将我的ip发送到cpanel时

#!/usr/bin/perl
# -------------------------------------------------------------------------------
# dns_update_script.pl
#
# Version 1.0 - 16.01.2012
#
# PERL script to dynamically update the IP of a host via the cPanel-API. This
# script was written to work with the Finnish hoster Neobitti but it might work
# with other hosters which use cPanel too.

在cPanel信息部分，我在我的文件（不是这个文件）中填写了我的cPanel用户名、密码和域。我像一个书呆子一样在公开文本中填写了这篇文章，却忽略了这件事：

  my $auth = "Basic " . MIME::Base64::encode( $user . ":" . $pass );

但我认为这不是问题所在

---

我认为问题出在XML:：Simple模块中，因为在调用该模块时脚本会停止，这在我看来似乎是idk。请提供帮助。

由于传递给

XMLin

的字符串不是有效的XML，因此您将收到该错误。您需要将输入修复为有效的XML

然而，这并不是因为解析XML时出现问题。在这种情况下使用的底层解析器（

expat

via XML:：parser）不会错误地声明有效的XML无效

您的程序应该检查请求是否成功（

$response->is_success

）。我怀疑您遇到了某种错误（例如403禁止）<代码>$response->status\u line可用于添加到错误消息中

---

（如果请求成功，也许您应该将

$response->as_string

打印出来，以检查响应，更好地了解发生了什么。）

我只是使用了这个shell脚本，并将它连接到我的crontab上，现在它每小时运行一次脚本，效果很好

---

对于我的raspberry pi web服务器

来说，他们甚至说不要使用它，而是支持许多更好的选择。。。但是，如果没有看到您提供给它的xml示例，我们还不能真的责怪它。。。可能xml格式错误，如错误所示？$result=$expat->parse（$arg）；您需要在问题中包含一个您试图解析的xml数据的示例。该脚本在尝试使用其结果之前似乎不会执行任何错误检查，以确保http请求成功，这也是值得研究的问题。（我不知道这是复制粘贴错误还是什么，但其中一个URL字符串中有一个新行不应该出现）

encode（$user.：“$pass）

应该是

encode（$user.：“$pass，””）

，但这不可能是问题所在。

  my $auth = "Basic " . MIME::Base64::encode( $user . ":" . $pass );
