Android, sending XML via HTTP POST (SOAP)

Question

I would like to invoke a webservice via Android. I need to POST some XML to a URL via HTTP. I found this snipped for sending a POST, but i dont know how to include/add the XML data itself.

public void postData() {          // Create a new HttpClient and Post Header            HttpClient httpclient = new DefaultHttpClient();            HttpPost httppost = new HttpPost("http://10.10.4.35:53011/");           try {                // Add your data                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);                nameValuePairs.add(new BasicNameValuePair("Content-Type", "application/soap+xml"));                             httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));                   // Where/how to add the XML data?                // Execute HTTP Post Request                HttpResponse response = httpclient.execute(httppost);             } catch (ClientProtocolException e) {                // TODO Auto-generated catch block            } catch (IOException e) {                // TODO Auto-generated catch block            }        } 

This is the complete POST message that i need to imitate:

POST /a8103e90-f1e3-11dd-bfdb-8b1fcff1a110 HTTP/1.1 Host: 10.10.4.35:53011 Content-Type: application/soap+xml Content-Length: 602  <?xml version='1.0' encoding='UTF-8' ?> <s12:Envelope xmlns:s12="http://www.w3.org/2003/05/soap-envelope" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing">   <s12:Header>     <wsa:MessageID>urn:uuid:fc061d40-3d63-11df-bfba-62764ccc0e48</wsa:MessageID>     <wsa:Action>http://schemas.xmlsoap.org/ws/2004/09/transfer/Get</wsa:Action>     <wsa:To>urn:uuid:a8103e90-f1e3-11dd-bfdb-8b1fcff1a110</wsa:To>     <wsa:ReplyTo>       <wsa:Address>http://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous</wsa:Address>     </wsa:ReplyTo>   </s12:Header>   <s12:Body /> </s12:Envelope> 

Answer 1

1. First, you can create a String template for this SOAP request and substitute user-supplied values at runtime in this template to create a valid request.
2. Wrap this string in a StringEntity and set its content type as text/xml
3. Set this entity in the SOAP request.

Something like:

HttpPost httppost = new HttpPost(SERVICE_EPR);           StringEntity se = new StringEntity(SOAPRequestXML,HTTP.UTF_8);  se.setContentType("text/xml");   httppost.setHeader("Content-Type","application/soap+xml;charset=UTF-8"); httppost.setEntity(se);    HttpClient httpclient = new DefaultHttpClient(); BasicHttpResponse httpResponse =      (BasicHttpResponse) httpclient.execute(httppost);  response.put("HTTPStatus",httpResponse.getStatusLine().toString());
