我已经使用this tutorial创建了一个Web服务。我已经成功创建了Web服务客户端。它对我来说很好。现在,我想从android调用此网络服务。我从两天以来一直没有任何结果。请帮助我解决此问题。
private static String SOAP_ACTION = "http://localhost:8080/MyFirstWebService/services/FirstWebService";
private static String NAMESPACE = "http://localhost:8080/MyFirstWebService/services/";
private static String METHOD_NAME = "addTwoNumbers";
private static String URL = "http://localhost:8080/MyFirstWebService/services/FirstWebService?wsdl";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//Initialize soap request + add parameters
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("firstNumber",""+5);
request.addProperty("secondNumber",""+5);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
// Make the soap call.
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
//this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION, envelope);
} catch (Exception e) {
e.printStackTrace();
}
// Get the SoapResult from the envelope body.
SoapObject result = (SoapObject)envelope.bodyIn;
Log.d("prabhu","result is ....."+result);
if(result != null){
TextView t = (TextView)this.findViewById(R.id.resultbox);
Log.d("prabhu","result is ....."+result.getProperty(0).toString());
t.setText("SOAP response:\n\n" + result.getProperty(0).toString());
}
}
这是我的wsdl:

这可能是Android SDK /模拟器上的DNS解析问题。采用ip地址而不是主机名。
请注意,在WSDL中,addTwoNumbers方法接受两个参数-firstNumber和secondNumber。在您的代码中,您都没有设置。
request.addProperty("Parameter","Value");
...可能应该是...
request.addProperty("firstNumber","2"); // Insert favorite first number here.
request.addProperty("secondNumber","2"); // Insert favorite second number here.
我发现有帮助的一件事是查看SOAP对话的发生情况。您可以通过两种方法来执行此操作。很多人打开Transport的调试标志,然后拆开SoapEnvelope的bodyIn和bodyOut成员var。但是对我来说,最简单的方法是启动WireShark,并查看通过有线发送的XML和HTTP标头。
我写了一个ksoap2-android教程,您可以在这里找到...

希望这可以帮助您将头枕固定在应该工作的方式上。
我得到了答案:localhost在Android中不起作用。我使用IP地址10.0.2.2代替了本地主机。感谢您的帮助。
根据您的WSDL,我建议您进行一些修改:
private static String SOAP_ACTION = "http://com.sencide/FirstWebService";
private static String NAMESPACE = "http://sencide.com";
private static String METHOD_NAME = "addTwoNumbers";
private static String URL = "http://localhost:8080/MyFirstWebService/services/FirstWebService?wsdl";
