Powershell / XML保存返回值和多个脚本

时间：2018-07-17 15:44:35

标签： xml powershell

我已经编写了XML代码来在Autotask中打开票证，并将其插入到PowerShell脚本中，因为它需要自动化。该脚本创建票证，我需要保存一个创建票证函数返回的值，以便随后可以在同一脚本中对其进行更新。有没有办法

  1. 随后在同一脚本中运行创建票证HTTP POST请求，然后再执行更新请求，并且
  2. 在脚本之间的某个地方保存由创建票证脚本返回的值<id></id>，然后将其用作更新票证脚本中的变量吗？
$RequestBody = @"

标头因包含敏感信息而被故意排除在外。

编辑：这是对请求的回复：

<soap:Envelope

    <createResponse xmlns="http://autotask.net/ATWS/v1_5/">
      <createResult>
        <ReturnCode>1</ReturnCode>
        <EntityResults>
          <Entity xsi:type="Ticket">
            <id>12345</id>
            <UserDefinedFields> 
              <UserDefinedField><Name>Escalated Internally?</Name></UserDefinedField>
              <UserDefinedField><Name>Ticket Category</Name></UserDefinedField>
              <UserDefinedField><Name>Escalated by Customer?</Name></UserDefinedField>
              <UserDefinedField><Name>Initial Severity</Name></UserDefinedField>
              <UserDefinedField><Name>Incident Start Date/Time</Name></UserDefinedField>
            </UserDefinedFields> 
          </Entity>
          <!-- etc. -->
        </EntityResults>
      </createResult>
    </createResponse>
  </soap:Body>
</soap:Envelope>

这只是一块巨大的田野。其中有一个名为<id></id>的字段，其值为整数，这正是我所需要的。

您可以使用简单的XPath query从响应XML中选择ID。但是请注意，您需要一个名称空间管理器，因为XML数据具有名称空间。我认为响应的属性为ResponseXml，具有已解析的XML数据，但事实并非如此，因此您可能需要这样的东西：

$rsp = Invoke-WebRequest -Uri $AUTOTASK -Method Post -Body $RequestBody ...
[xml]$xml = $rsp.Content
$nm = New-Object Xml.XmlNamespaceManager $xml.NameTable
$nm.AddNamespace('ns', 'http://autotask.net/ATWS/v1_5/')
$id = $xml.SelectSingleNode('//ns:id', $nm).'#text'

您还可以使用点访问，在这种特定情况下，这可能是更简单的方法，因为它绕过名称空间并自动扩展叶节点的值：

$rsp = Invoke-WebRequest -Uri $AUTOTASK -Method Post -Body $RequestBody ...
[xml]$xml = $rsp.Content
$id = $xml.Envelope.Body.createResponse.createResult.EntityResults.Entity.id
