SOAP的请求在Web Service是无处不在的，像WCF服务和传统ASMX asp.net的web Service。如果要测试SOAP服务是否好用通过web编程来实现就显得太过于复杂了，下面的脚本片段(snippet)将会轻而易举的完成通过powershell测试和调用SOAP服务：
function Execute-SOAPRequest
(
[Xml] $SOAPRequest,
[String] $URL
)
{
write-host "Sending SOAP Request To Server: $URL"
$soapWebRequest = [System.Net.WebRequest]::Create($URL)
$soapWebRequest.Headers.Add("SOAPAction","`"
http://www.facilities.co.za/valid8service/valid8service/Valid8Address`"")
$soapWebRequest.ContentType = "text/xml;charset=`"utf-8`""
$soapWebRequest.Accept = "text/xml"
$soapWebRequest.Method = "POST"
write-host "Initiating Send."
$requestStream = $soapWebRequest.GetRequestStream()
$SOAPRequest.Save($requestStream)
$requestStream.Close()
write-host "Send Complete, Waiting For Response."
$resp = $soapWebRequest.GetResponse()
$responseStream = $resp.GetResponseStream()
$soapReader = [System.IO.StreamReader]($responseStream)
$ReturnXml = [Xml] $soapReader.ReadToEnd()
$responseStream.Close()
write-host "Response Received."
return $ReturnXml
}
$url = 'http://www.facilities.co.za/valid8service/valid8service.asmx'
$soap = [xml]@'
<?xml version="1.0" encoding="utf-8"?>
<soap12:Envelope xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="
http://www.w3.org/2001/XMLSchema" xmlns:soap12="
http://www.w3.org/2003/05/soap-envelope">
<soap12:Body>
<Valid8Address xmlns="
http://www.facilities.co.za/valid8service/valid8service">
<ID>string</ID>
<Address1></Address1>
<Address2></Address2>
<Address3></Address3>
<Address4></Address4>
<Address5></Address5>
<Address6></Address6>
<PostCode></PostCode>
</Valid8Address>
</soap12:Body>
</soap12:Envelope>
'@
$ret = Execute-SOAPRequest $soap $url
在这里得到的$ret变量中存储的是System.Xml.XmlDocument对象，如果需要查看其中的具体内容可以通过Export-Clixml这个cmdlet将其输出到本地文件中查看。
