Comment appeler un webservice SOAP avec une simple Chaîne de caractères (xml dans un format de chaîne)

Solution:

private byte[] callSOAPServer() {
byte[] result = null;
HttpParams httpParameters = new BasicHttpParams();
//Set the timeout in milliseconds until a connection is established.
int timeoutConnection = 15000;
HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);
//Set the default socket timeout (SO_TIMEOUT)
//in milliseconds which is the timeout for waiting for data.
int timeoutSocket = 35000;
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
DefaultHttpClient httpclient = new DefaultHttpClient(httpParameters);
/*
* httpclient.getCredentialsProvider().setCredentials( new
* AuthScope("os.icloud.com", 80, null, "Digest"), new
* UsernamePasswordCredentials(username, password));
*/
HttpPost httppost = new HttpPost(SERVER_URL );
httppost.setHeader("soapaction", SOAP_ACTION);
httppost.setHeader("Content-Type", "text/xml; charset=utf-8");
System.out.println("executing request" + httppost.getRequestLine());
//now create a soap request message as follows:
final StringBuffer soap = new StringBuffer();
soap.append("\n");
soap.append("");
//this is a sample data..you have create your own required data  BEGIN
soap.append(" \n");
soap.append(" \n");
soap.append("" + body);
soap.append(" \n");
soap.append(" \n");
/* soap.append(body); */
//END of MEssage Body
soap.append("");
Log.i("SOAP Request", ""+soap.toString());
//END of full SOAP request  message
try {
HttpEntity entity = new StringEntity(soap.toString(),HTTP.UTF_8);
httppost.setEntity(entity); 
HttpResponse response = httpclient.execute(httppost);//calling server
HttpEntity r_entity = response.getEntity();  //get response
Log.i("Reponse Header", "Begin...");          //response headers
Log.i("Reponse Header", "StatusLine:"+response.getStatusLine());
Header[] headers = response.getAllHeaders();
for(Header h:headers){
Log.i("Reponse Header",h.getName() + ": " + h.getValue());
}
Log.i("Reponse Header", "END...");
if (r_entity != null) {       
result = new byte[(int) r_entity.getContentLength()];  
if (r_entity.isStreaming()) {
DataInputStream is = new DataInputStream(
r_entity.getContent());
is.readFully(result);
}
}
} catch (Exception E) {
Log.i("Exception While Connecting", ""+E.getMessage());
E.printStackTrace();
}
httpclient.getConnectionManager().shutdown(); //shut down the connection
return result;
}

2), Vous devez analyser la sortie de la fonction ci-dessus est retourné byteArray. Par exemple:

byte[] initReqrepsonse = callSOAPServer(soapBodymessage );
ByteArrayInputStream bais=new ByteArrayInputStream(initReqrepsonse);
//now parse the xml as
/** Handling XML */
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
/** Create handler to handle XML Tags ( extends DefaultHandler ) */
//ResponseParser  is XML parser class which will parse the XML output.
ResponseParser myXMLHandler = new ResponseParser();
xr.setContentHandler(myXMLHandler);
Log.i("XML data", bais.toString());
xr.parse(new InputSource(bais));

De cette façon,vous pouvez accéder à un webservice SOAP méthodes sans les bibliothèques de tiers.
