如何通过 android 使用 .net 网络服务？
我的代码是这样的...
package Webservices.pck;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.widget.TextView;
import android.app.Activity;
import android.os.Bundle;
public class Webservices extends Activity
{
private static final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
private static final String METHOD_NAME = "HelloWorld";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://ipaddress/Service1.asmx";
//private Object resultRequestSOAP = null;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
try
{
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;
envelope.dotNet = true;
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject resultRequestSOAP = (SoapObject)envelope.bodyIn;
String result = (String)resultRequestSOAP.getProperty(0).toString();
tv.setText(result);
this.setContentView(tv);
}
catch (Exception aE)
{
tv.setText(aE.toString());
this.setContentView(tv);
}
}
}
在我使用的这段代码中。
String URL = "http://ipaddress/Service1.asmx";
然后错误:-- org.xmlpull.v1.xmlPullParserException: expected:START_TAG {http://schemas.xmlsoap.org/soap/envelope/}Envelope(position:START_TAG<html>@1:6 in java.io.InputStreamReader@4375fda8)
最佳答案
您访问的是 html 页面而不是 SOAP 服务。解析器异常已经告诉你出了什么问题。
你有这样的数据
<html><body>... </body></html>
虽然页面应该返回类似的内容
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<YourFunctionToCall... />
</soapenv:Body>
</soapenv:Envelope>
也许您的 URL 中有拼写错误，或者某种身份验证或某种其他类型的错误，因此它返回了 HTML 错误而不是 Soap 请求/响应。
