perl 標簽不匹配，問題 = XML::Simple 模塊？

Question

當我嘗試運行此腳本將我的 ip 發送到 cpanel 時...

#!/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.

...我收到此錯誤：

mismatched tag at line 37, column 2, byte 4634 at /usr/lib/arm-linux-gnueabihf/perl5/5.28/XML/Parser.pm line 187.
XML::Simple called at dns_update_script.pl line 55.

在 cPanel 信息部分，我在我的文件中填寫了我的 cPanel 用戶名、密碼和域（不是這個）。 我像菜鳥一樣在開放文本中填寫了這個並忽略了這個東西：

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

但我不認為這是問題所在。

我認為問題出在 XML::Simple 模塊中，因為在調用該模塊時腳本會停止，但在我看來似乎是 idk。 請幫忙。

Answer 1

您收到該錯誤是因為您傳遞給XMLin的字符串不是有效的 XML。 您需要將輸入修正為有效的 XML。

雖然我強烈建議不要使用 XML::Simple ，但這並不是因為解析 XML 的問題。 在這種情況下使用的底層解析器（ expat via XML::Parser）並不因錯誤地聲稱有效的 XML 無效而為人所知。

您的程序應該檢查請求是否成功（ $response->is_success ）。 我懷疑您遇到了某種錯誤（例如 403 Forbidden）。 $response->status_line可用於添加到您的錯誤消息中。

（如果請求成功，也許您應該打印$response->as_string來檢查響應以更好地了解正在發生的事情。）

Answer 2

我只是使用了這個 shell 腳本並將它連接到我的 crontab，現在它每小時運行一次腳本並且它工作正常。
