Ksoap2_connect to WebService

* ***** I am a small knowledge point ********

Ksoap2 provides better support for soap serialization. Ksoap2 is a lightweight implementation framework of the j2's platform. It provides the soap protocol message

Assembly, network post, network return, resolution, and other functions.

**********

1. Import the KSOAP2.jar package to the Project

2. Access the. net URL and find the agreed URL namespace and access method.

String SERVICE_NS = "http://tempuri.org /";
String methodName = "mydata ";

3. Create a SoapObject and input the namespace of the Web Service to be called. The Web Service method name

SoapObject soapObject = new SoapObject (SERVICE_NS, methodName );

4. Pass the parameters to the Web Service server and call the addProperty (String name, Object value) method of the SoapObject Object to set the parameters. (Name is the parameter name agreed by android and. net)

SoapObject. addProperty ("L", con );

5. Use the SOA1.1 protocol to create an Envelop object and set compatibility with the WebService provided by. net.

// Generate soap information for WebService method call and specify the Soap version

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope (SoapEnvelope. VER10 );
Envelope. bodyOut = soapObject;

Envelope. dotNet = true; // whether to call the WebService developed by DotNet

6. Create an HttpTransportSE transmission object and pass in the WebService server address

String SERVICE_URL = "http: // 192.168.66.66: 82/data. asmx ";

HttpTransportSE ht = new HttpTransportSE (SERVICE_URL );

7. call the call method of the HttpTransportSE object. The first parameter of the call is the namespace + Web service method name, and the second parameter is the object of SoapSerializationEnvelope.

Ht. call (SERVICE_NS + methodName, envelope );

8. If the returned value is a string, the method for receiving the returned parameters is: envelope and envelioe. getResponse, the object of SoapSerializationEnvelope, and receiving the returned value.

If (envelope. getResponse ()! = Null ){

String s = envelope. getResponse (). toString ();

}

***********

1. The namespace must be consistent with the URL format

2. The method name must be consistent with. net.

3. Note that the SOAP version is 10/11/12. You can check the first version of the xml file in. net or try all three.

4. During the call, it cannot be placed in the main thread, but it must be placed in the asynchronous thread call.
