PowerShell小技巧之执行SOAP请求

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：

这是一段程序代码。

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。

这是一段程序代码。

$ret | Export-Clixml  c:\1.xml;Get-Content c:\1.xml
