Android_webservices_ Source Code Analysis

this blog post for the original, reproduced please specify the source! http://blog.csdn.net/zimo2013/article/details/38037989in the Android_webservices_ introduction article, the basic knowledge of webservices is briefly introduced. The following main analysis Ksoap2-android-assembly-3.3.0-jar-with-dependencies.jar implement the source code. 1. Call the webservices process

public void Getremoteinfo (string phonesec) {string nameSpace = "http://WebXml.com.cn/"; String methodName = "Getmobilecodeinfo"; String endPoint = "Http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx"; String soapaction = "http://WebXml.com.cn/getMobileCodeInfo";//1. Initialize the Soapobject object. Sets the number of parameters for the method. Equivalent to the body soapobject request = new Soapobject (NameSpace, methodName); Request.addproperty ("Mobilecode", phonesec); Request.addproperty ("UserId", "");//2. Instantiate the Soapserializationenvelope object, equivalent to Chimpi soapserializationenvelope envelope = new Soapserializationenvelope (SOAPENVELOPE.VER10); envelope.bodyout = Request;envelope.dotnet = true;// Compatible with. NET Development net-services//3. Instantiate the Httptransportse object, and you can specify the request time Httptransportse transport = new Httptransportse ( EndPoint);//httptransportse transport = new Httptransportse (endPoint, timeout); try {//4. Core method Invocation, Among them, Soapacton is invalid at Soapserializationenvelope.ver12, and Transport.call for POST request (SOAPAction, envelope); Soapobject response = (soapobject) envelope.bodyin;final String result = responsE.getproperty (0). toString ();//vectortoast (result);} catch (Exception e) {e.printstacktrace (); Toast (E.getmessage ());}}
