Android中如何使用这个WebService呢？

Question

我正在开发一个应用程序来使用Web服务，如何使用以下Web服务？ http方法还是ksoap2？我尝试了 Ksoap2，似乎无法正确提取此 Web 服务，有人可以帮忙吗？提前致谢。

这是 wsdl： http://www.restfulwebservices.net/wcf/StockQuoteService.svc？ wsdl

NAME_SPACE 是： http://www.restfulwebservices.net/ServiceContracts/ 2008/01？方法是GetStockQuote？ SOAP_ACTION 是 GetStockQuote？

这是请求转储：

    <v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:d="http://www.w3.org/2001/XMLSchema"
    xmlns:c="http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:v="http://schemas.xmlsoap.org/soap/envelope/">
      <v:Header />
      <v:Body>
        <GetStockQuote xmlns="http://www.restfulwebservices.net/ServiceContracts/2008/01"
        id="o0" c:root="1">
          <parameters i:type="d:string">IBM</parameters>
        </GetStockQuote>
      </v:Body>
    </v:Envelope>

响应转储：

    <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
      <s:Body>
        <s:Fault>
          <faultcode xmlns:a="http://schemas.microsoft.com/net/2005/12/windowscommunicationfoundation/dispatcher">
