PowerShell错误具有完整的SOAP响应而不是内容

Question

我在调用一个SOAP API。PowerShell给出了一个错误，这个错误包含了我所期望的响应！而我发送响应的变量的内容缺少一些数据。

[xml]$response = Invoke-WebRequest -Uri $UserURI -Method POST -ContentType "test/xml;charset=utf-8" -Body $input

$SOAPResponse = [xml]$response.Content

Invoke-WebRequest : <?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"

<description>Error</description><errors><item><id>52001</id><description>Unable

$SOAPResponse.Envelope.Body.AddUserResponse.AddUserResult.errors

$SOAPResponse.Envelope.Body.FirstChild.InnerXml

<AddUserResult><errorcode>200</errorcode><description>OK</description><errors /></AddUserResult>

为空！

SOAPUI给出了正确的错误：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="https://test.safetylearning.co.uk/api/1.3/UserManagement">
   <SOAP-ENV:Body>

            <description>Error</description>
            <errors>
               <item>

               </item>
               <item>
                  <id>0</id>
                  <description>A user identified by ID ['9999'] exists</description>
               </item>
            </errors>
         </AddUserResult>
      </ns1:AddUserResponse>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

您需要将请求包装在try/Catch中，并在Catch块中引用$error[0].errorDetails。该特定用户错误将随以下Catch块返回：

try {
[xml]$response = Invoke-WebRequest -Uri $UserURI -Method POST -ContentType "test/xml;charset=utf-8" -Body $input
$SOAPResponse = [xml]$response.Content
$SOAPResponse
]

catch {
[xml]$errResponse = $error[0].ErrorDetails
$errCode = $errResponse.Envelope.body.AddUserResponse.AddUserResult.errors.ChildNodes[2].description
$errCode
}

该块将输出有效的SOAP响应，或者只是从错误中隐藏在SOAP信封中的错误代码

$errResponse.Envelope.body.AddUserResponse.AddUserResult.errors.ChildNodes[2].description
A user identified by ID ['9991'] exists
