如何在android中发送soap请求？

Question

我是WSDL webservices的新手,使用KSoap2库在android中调用wsdl webservices.

这是我的soap请求转储

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:loy="http://loyalcard.com/LoyalCardWebService/">;
   <soapenv:Header/>
   <soapenv:Body>
      <loy:GetOffersByLocation>
         <!--Optional:-->
         <loy:Location>
            <!--Optional:-->
            <loy:Latitude>?</loy:Latitude>
            <!--Optional:-->
            <loy:Longitude>?</loy:Longitude>
         </loy:Location>
      </loy:GetOffersByLocation>
   </soapenv:Body>
</soapenv:Envelope>

我正在传递这个SopaObject,如:

 PropertyInfo latitude = new PropertyInfo();
        latitude.name="Latitude";
        latitude.type=Double.class;
        latitude.setValue(32.806673);

   PropertyInfo longitude = new PropertyInfo();
        longitude.name="Longitude";
        longitude.type=Double.class;
        longitude.setValue(-86.791133);

        SoapObject results = null;
        String methodName = "OffersByLocation";
        String actionName = "http://loyalcard.com/LoyalCardWebService/GetOffersByLocation";
        SoapObject request = new SoapObject(NAMESPACE,methodName);

        request.addProperty(latitude);
        request.addProperty(longitude);

这里将纬度和经度值直接传递给OffersByLocation,我应该通过元素Location.请任何人都可以帮助如何通过位置传递参数.

我已尝试过以上程序,但我得到错误说

06-17 11:52:55.934: WARN/System.err(350): SoapFault - faultcode: 'soapenv:Server' faultstring: 'org.apache.axis2.databinding.ADBException: Unexpected subelement Latitude' faultactor: 'null' detail: org.kxml2.kdom.Node@44f6ddc0

请任何人告诉我如何在Soap对象中传递上面的SOAP Request转储？

您还可以手动构造请求XML,并将其发送到kSOAP以进行发送和响应处理.您可以使用soapUI编写请求XML,然后res/raw使用关键字保存它们,例如{%key%}应在运行时放置参数.以下是替换关键字的代码:

// parse the template and replace all keywords
StringBuffer sb = new StringBuffer();
try {
  // find all keywords
  Pattern patern = Pattern.compile("\\{%(.*?)%\\}");
  Matcher matcher = patern.matcher(templateHtml);

  while (matcher.find()) {
    String keyName = matcher.group(1);
    String keyValue = values.get(keyName);
    if (keyValue == null) {
      keyValue = "";
    }
    // replace the key with value
    matcher.appendReplacement(sb, keyValue);
  }
  matcher.appendTail(sb);

  // return the final string
  return sb.toString();
} catch (Throwable e) {
  Log.e(LOG_TAG, "Error parsing template", e);
  return null;
}

要使用kSOAP发送自定义XML请求,您需要创建自己的Transport类.

或者您可以使用手动发送请求DefaultHttpClient(请参阅在Android上使用客户端/服务器证书进行双向身份验证SSL套接字),并仅使用kSOAP来解析响应.

   * 
   * @param requestContent the SOAP request XML

  public Object sendSoapRequest(String requestContent)

    // process SOAP response
    parseResponse(responseIs, envelope);

    Object bodyIn = envelope.bodyIn;
    if (bodyIn instanceof SoapFault) {
      throw (SoapFault) bodyIn;
    }

    return bodyIn;
