如何通过powershell访问wsdl的命令？

Question

我注意到使用这个脚本：

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$id = "idofadmin"
$pw = 'Admin123password'
$wsdl = "https://siteofwsdl.dom.com/services/MainService?wsdl"
$p = New-WebServiceProxy –Uri $wsdl
$p|Get-Member
$p.GetEntityFields(96)

返回wsdl的所有属性。但是，使用$ p.getEntityFields命令（以及所有其他命令）将继续返回错误“无法找到重载参数”类型的错误。该网站有关于getEntityFields命令的说法。

<xs:element name="getEntityFields">
 <xs:complexType>
  <xs:sequence>
   <xs:element name="sessionId" type="xs:string" minOccurs="0" nillable="true"/>
   <xs:element name="entityTypeId" type="xs:long" minOccurs="0"/>
   <xs:element name="mode" type="xs:long" minOccurs="0"/>
  </xs:sequence>
 </xs:complexType>
</xs:element>

该网站还提供了一个肥皂请求示例，该请求通常会提取实体数据 -

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ser="http://services">
 <soapenv:Header/>
  <soapenv:Body>
   <ser:getEntityFields>
    <ser:sessionId>F0C6EDD44B270B1F3DD0F1492A2A1585</ser:sessionId>
    <ser:entityTypeId>96</ser:entityTypeId>        
    <ser:mode>1</ser:mode>
   </ser:getEntityFields>
  </soapenv:Body>
</soapenv:Envelope>

在PowerShell中，我需要对getEntityField命令发出代理请求？我猜是像p.getEntityFields这样的东西，其参数是sessionID，96因为它是我想要的特定的，而模式类型0因为我只想“读”它。如果那是对的 - 我如何获得会话ID？顺便说一下，网站使用的soap版本的输出是响应（部分）

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">

   <soapenv:Body>

      <ns:getEntityFieldsResponse xmlns:ns="http://services" xmlns:ax21="http://objects.services/xsd">

Answer 1

通过一些试验和错误，我能够回答这个问题 - 如果这里有额外的代码，请告诉我，我可以删除它。但以下确实适用于我试图访问的wsdl。看起来这里不需要xmlsoap和invoke-webrequest，因为从新的WebServiceProxy开始的一切都是我们真正想要的工作。如果您输入不带任何（）的命令，则实际请求命令的参数。 PowerShell为您提供了预期数据类型列表 - 强制我在需要时使用类型[ref]。

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
$id = "idoflogin"
$pw = 'adminpw'
$wsdl = "https://site.dom.com/services/MainService?wsdl"
$p = New-WebServiceProxy -Uri $wsdl -Credential $creds -Namespace Proxy 
$sessionD = $p.login($id, $pw, $false, $false)
$p.getEntityFields($sessionD, '96', '0', '1', '0')
$p.logout($sessionD, [ref]$false, [ref]$false)
