因此，我正在尝试做一些看起来与“通过 augeas 向 XML 根节点添加属性的问题”中的问题相同的事情，但是那里提供的答案对我不起作用。如果没有插入命令，我会收到此错误消息（在puppet agent -t --debug --verbose模式下）：

Debug: Augeas[context.xml](provider=augeas): /augeas/files/usr/share/tomcat/conf/context.xml/error/message = Failed to match

Debug: Augeas[context.xml](provider=augeas): Closed the augeas connection

这基本上就是我们在另一篇文章中看到的。使用插入命令，这是我正在使用的相关代码：

class mytomcat::hardening::context-xml {
  require ::augeas
  augeas{ 'context.xml':
    lens    => 'Xml.lns',
    incl    => '/usr/share/tomcat/conf/context.xml',
    changes => [
      'ins #attribute before Context/#text',
      'set Context/#attribute/allowLinking false', 
    ],
  }
}

这给了我这个错误：

Debug: Augeas[context.xml](provider=augeas): sending command 'ins' with params ["#attribute", "before", "/files/usr/share/tomcat/conf/context.xml/Context/#text"]
Debug: Augeas[context.xml](provider=augeas): Closed the augeas connection
Error: /Stage[main]/mytomcat::Hardening::Context-xml/Augeas[context.xml]: Could not evaluate: Error sending command 'ins' with params ["#attribute", "before", "/files/usr/share/tomcat/conf/context.xml/Context/#text"]/Error sending command 'ins' with params ["#attribute", "before", "/files/usr/share/tomcat/conf/context.xml/Context/#text"]

我尝试使用touch而不是insert，基于Augeas的“ Puppet Type Reference ”页面，使用以下代码：

class mytomcat::hardening::context-xml {
  require ::augeas
  augeas{ 'context.xml':
    lens    => 'Xml.lns',
    incl    => '/usr/share/tomcat/conf/context.xml',
    changes => [
      'touch Context/#attribute',
      'touch Context/#attribute/allowLinking',
      'set Context/#attribute/allowLinking false', 
    ],
  }
}

但后来我收到错误消息：

Error: /Stage[main]/mytomcat::Hardening::Context-xml/Augeas[context.xml]: Could not evaluate: Unknown command touch

编辑：我尝试做一个clear而不是触摸，但这似乎是一个 NOOP 命令，并没有给我一个与本文最顶部显示的第一个不同的结果。

所以，我做不到touch，使用完整的 XPath 尝试设置属性不起作用，因为您必须在 #text 节点之前添加 #attribute 节点，这clear似乎是 NOOP，然后当我尝试做推荐的“插入”命令也不起作用。

知道这里出了什么问题以及如何解决吗？
