我正在尝试创建一个脚本，该脚本将使用 powershell 和 invoke-webrequest 自动升级 NSX，以利用 NSX Manager 的 API 调用。我已经完成了脚本，但脚本的某些部分我需要检查并匹配响应中的某些数据。事实上，NSX API 响应 90% 都是 xml 格式，但有时也可以是 json 格式。
如果响应采用 json 格式，我的匹配将无法工作，而且脚本的某些部分也将无法工作，因为它需要 xml，并且无法将 json 转换为 xml。
据我了解，从 powershell v4 开始，您可以添加接受标头，但问题是我已经在使用一个标头进行授权。
是否可以在 powershell 中的 invoke-webrequest 中添加多个标头，如果可以，会怎样。
以下是我拥有的脚本的一部分，它将检查已部署的 NSX 的当前版本。因此它将匹配响应中显示版本的值。

$NSXPassword = "VMware1!"
$uriP = "https://HQ-NSX-01a.nsx.gss"

如果是 xml 格式，则响应如下，我将匹配版本。
<?xml version="1.0" encoding="UTF-8"?>
<globalInfo>
<currentLoggedInUser>admin</currentLoggedInUser>
<versionInfo>
<majorVersion>6</majorVersion>
<minorVersion>1</minorVersion>
<patchVersion>5</patchVersion>
<buildNumber>3102213</buildNumber> <<<--- this is my match
</versionInfo>
</globalInfo>
如果响应是 xml 格式（90% 的情况下），上面的脚本将正常工作，但如果它是 json，我将收到以下错误，并且脚本将退出。
Cannot convert value "{"currentLoggedInUser":"admin","versionInfo":{"majorVersion":"6","minorVersion":"1","patchVersion":"5","buildNumber":"3102213"}}"
to type "System.Xml.XmlDocument". Error: "The specified node cannot be inserted as the valid child of this node, because the specified node is the wrong

非常感谢您的帮助。
