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="">
  <soap12:body>
    <valid8address xmlns="">
      <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
