I need to connect to webservice, which requers authorization. I tried to use headers:
Element usernameElement = new Element().createElement(NAMESPACE, "Username");
usernameElement.addChild(Node.TEXT, "user");
Element passwordElement = new Element().createElement(NAMESPACE, "Password");
passwordElement.addChild(Node.TEXT, "pass");
Element header = new Element().createElement(NAMESPACE, "AuthHeader");
header.addChild(Node.ELEMENT, usernameElement);
header.addChild(Node.ELEMENT, passwordElement);
soapEnvelope.headerOut= new Element[]{header};
I receive the error: 07-25 14:03:20.922: WARN/System.err(584): org.xmlpull.v1.XmlPullParserException: expected: START_TAG {http://schemas.xmlsoap.org/soap/envelope/}Envelope (position:START_TAG @1:6 in java.io.InputStreamReader@44f632f8)
I understand, webservice is returning some HTML formatted error, but how can i see what is it? Can i make textview.settext() of such a request or print it to LogCat? How can i make it and Why am i receiving it?:(
Then, i tried to use HttpTransportBasicAuth class - faced a lot of problems to make it work - i had to add it to the project, change manually its extension from HttpTransport to HttpTransportSE and from ServiceConnectionMIDP to ServiceConnectionSE because there wasn't such classes in ksoap2-android-assembly-2.5.7. At last it compiled without errors:
package com.android.testinet;
import org.ksoap2.transport.*;
import org.ksoap2.transport.HttpTransportSE;
import java.io.*;
public class HttpTransportBasicAuth extends HttpTransportSE {
private String username;
private String password;
/**
* Constructor with username and password
*
* @param url
* The url address of the webservice endpoint
* @param username
* Username for the Basic Authentication challenge RFC 2617
* @param password
* Password for the Basic Authentication challenge RFC 2617
*/
public HttpTransportBasicAuth(String url, String username, String password) {
super(url);
this.username = username;
this.password = password;
}
protected ServiceConnection getServiceConnection() throws IOException {
ServiceConnectionSE midpConnection = new ServiceConnectionSE(url);
addBasicAuthentication(midpConnection);
return midpConnection;
}
protected void addBasicAuthentication(ServiceConnection midpConnection) throws IOException {
if (username != null && password != null) {
StringBuffer buf = new StringBuffer(username);
buf.append(':').append(password);
byte[] raw = buf.toString().getBytes();
buf.setLength(0);
buf.append("Basic ");
org.kobjects.base64.Base64.encode(raw, 0, raw.length, buf);
midpConnection.setRequestProperty("Authorization", buf.toString());
}
}
} it is ok now with the HttpTransportBasicAuth.call method, as there is no an error, but i'm still receiving the error: 07-25 14:03:20.922: WARN/System.err(584): org.xmlpull.v1.XmlPullParserException: expected: START_TAG {http://schemas.xmlsoap.org/soap/envelope/}Envelope (position:START_TAG @1:6 in java.io.InputStreamReader@44f632f8) when i run project. Here's my code by which i try to connect to webservice:
HttpTransportBasicAuth aht= new HttpTransportBasicAuth(URL, "user", "pass");
try
{
aht.call(SOAP_ACTION, soapEnvelope);
SoapPrimitive tmp_ResultString = (SoapPrimitive) soapEnvelope.getResponse();
ResultString = tmp_ResultString.toString();
// tv.setText(ResultString);
}
catch(Exception e)
{
e.printStackTrace();
}
And finally, i tried to use this source:
Webservice Http Authentication - KSOAP2 on Android
but compiler do not know what HeaderProperty is. What should i import to be it ok?
Please answer how can i see what the exact error message webservice returns in <html> tag, because of what i'm receiving the error in LogCat and please answer if i'm doing anything wrong while trying to make it work.
