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。

复制代码 代码如下:
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]@'
<"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。

复制代码 代码如下:
$ret | Export-Clixml  c:\1.xml;Get-Content c:\1.xml
