Hallo to all members of stackoverflow.
Im new in Android dev,can anybody tell me how to Post data on a website or give me a sampler ?
I want to Post hashes to a online cracker and get the resuld back as string.
edit_box = enter the hash
sendbutton = send the hash
text_view = resuld
http://xdecrypt.com/#
thanks
EDIT: I take a look # Live headers and found this resuld
http://xdecrypt.com/ajax/liste.php?hash=759fdfa1a99563aa6309bb6ae27537c564547f62
Here we can add the hash to the Url and the resuld is.
document.getElementById('hashresult').value="";document.getElementById('hashresult').value+="759fdfa1a99563aa6309bb6ae27537c564547f62(MySQL)=amande1975 ";
Now i want to read this as string anybody can help ?
I want to Display the the Hashtype MySQL and the password amande1975.
And display it as text_view,on the ui.
Thanks again.
EDIT:2 Its Works but how to split the string now ? Anybody can help ?
try {
String webPage = "http://xdecrypt.com/ajax/liste.php?hash="+hashedit.getText().toString();
URL url = new URL(webPage);
URLConnection urlConnection = url.openConnection();
InputStream is = urlConnection.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
int numCharsRead;
char[] charArray = new char[1024];
StringBuffer sb = new StringBuffer();
while ((numCharsRead = isr.read(charArray)) > 0) {
sb.append(charArray, 0, numCharsRead);
}
String result = sb.toString();
System.out.println("*** BEGIN ***");
System.out.println(result);
System.out.println("*** END ***");
TextView tv2 = (TextView) findViewById(R.id.textView2);
tv2.setText("HashResuld="+sb.toString());
EDIT3: Its works ;)
Thanks again for No help ;)
I have done a fair bit of research before and ksoap2 has the abilities to do data transfers with webservice urls and I believe that it has other http functionalities which you could use.
http://ksoap2.sourceforge.net/
download ksoap2 and import to your project and create you service access layer as such:
import java.util.ArrayList;
import java.util.List;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.ksoap2.SoapEnvelope;
public class ServiceAccess {
private static String Namespace;
private static String MethodName;
private static String URL;
private SoapSerializationEnvelope Envelope;
private SoapObject SoapRequest;
private SoapPrimitive Response;
private List<PropertyInfo> methodParamList;
public ServiceAccess(String webserviceUrl, String methodName) throws Exception
{
setUrl(webserviceUrl);
setMethodName(methodName);
setNamespace("http://tempuri.org/");
SoapRequest = new SoapObject(this.getNamespace(), this.getMethodName());
methodParamList = new ArrayList<PropertyInfo>();
}
protected String getUrl()
{
return URL;
}
protected void setUrl(String url)
{
URL = url;
}
protected String getMethodName()
{
return MethodName;
}
protected void setMethodName(String methodName)
{
MethodName = methodName;
}
protected String getNamespace()
{
return Namespace;
}
protected void setNamespace(String namespace)
{
Namespace = namespace;
}
protected String SoapAction()
{
String SOAP_ACTION = this.getNamespace() + this.getMethodName();
return SOAP_ACTION;
}
protected void CreateSoapRequest() throws Exception
{
try
{
if(methodParamList.size()>0){
for(PropertyInfo propInfo : methodParamList)
{
SoapRequest.addProperty(propInfo.getName(), propInfo.getValue());
}
}
}catch(Exception ex){
throw ex;
}
}
public <T> void addMethodParameters(String paramName, T val)
{
PropertyInfo prop = new PropertyInfo();
prop.setName(paramName);
prop.setValue(val);
prop.setType(val.getClass());
methodParamList.add(prop);
}
protected SoapSerializationEnvelope createEnvelope() throws Exception
{
this.CreateSoapRequest();
try{
Envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
Envelope.dotNet = true;
Envelope.setOutputSoapObject(SoapRequest);
}catch(Exception ex){
throw ex;
}
return Envelope;
}
public String getResponse() throws Exception
{
try{
this.createEnvelope();
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(this.SoapAction(), Envelope);
Response = (SoapPrimitive) Envelope.getResponse();
}catch(Exception ex){
throw ex;
}
return Response.toString();
}
}
You can tweak around with it to use various urls of web pages instead of webservice urls.

I am getting null for one of the selected column with IterableCSVToBean<MessageFileExtractHeader>
DTO Classe:
public class MessageFileExtractHeader implements Serializable {
private static final long serialVersionUID = -3052197544136826142L;

MessageFileExtractHeader msgFilxtractRecord = null;
try {

SAADumpFileExtraction.class.getClassLoader().getResourceAsStream("config.properties");
prop.load(inputStream);
} catch (IOException e) {

}
String fileDirectory= prop.getProperty("file.directory");
//get the filenames
String mesgfilename= fileDirectory+prop.getProperty("mesg.file.name");
//get the headers
String mesgheader= fileDirectory+prop.getProperty("mesg.file.header.fields");
int msgskiplines=1;
CSVReader reader = null;
try {

Map<String, String> msgmapping = efUtils.getMapping(mesgheader);

while(mesgIterator.hasNext()){
msgFilxtractRecord = mesgIterator.next();
System.out.println(msgFilxtractRecord);
//
}} finally {

}
}
}
Output:
MessageFileExtractHeaders [mesgid=null, mesg_type=081]
Please suggest me good solution to get the mesgid.
Please send an short sample of your csv file (header and one line) and the value of your header property.
My guess is there is a type in either the csv header, the headers in the property or both and it does not match what is in the DTO (mesgid). Because of that it will not be populated.
Using the default Visual Studio 2013 Web API project template with individual user accounts, and posting to the /token endpoint with an Accept header of application/xml, the server still returns the response in JSON:
{"access_token":"...","token_type":"bearer","expires_in":1209599}
Is there a way to get the token back as XML?
According to RFC6749 the response format should be JSON and Microsoft implemented it accordingly. I found out that JSON formatting is implemented in Microsoft.Owin.Security.OAuth.OAuthAuthorizationServerHandler internal class with no means of extension.
I also encountered the need to have token response in XML.
The best solution I came up with was to implement HttpModule converting JSON to XML when stated in Accept header.
public class OAuthTokenXmlResponseHttpModule : IHttpModule
{
private static readonly string FilterKey = typeof(OAuthTokenXmlResponseHttpModule).Name + typeof(MemoryStreamFilter).Name;
public void Init(HttpApplication application)
{
application.BeginRequest += ApplicationOnBeginRequest;
application.EndRequest += ApplicationOnEndRequest;
}
private static void ApplicationOnBeginRequest(object sender, EventArgs eventArgs)
{
var application = (HttpApplication)sender;
if (ShouldConvertToXml(application.Context.Request) == false) return;
var filter = new MemoryStreamFilter(application.Response.Filter);
application.Response.Filter = filter;
application.Context.Items[FilterKey] = filter;
}
private static bool ShouldConvertToXml(HttpRequest request)
{
var isTokenPath = string.Equals("/token", request.Path, StringComparison.InvariantCultureIgnoreCase);
var header = request.Headers["Accept"];
return isTokenPath && (header == "text/xml" || header == "application/xml");
}
private static void ApplicationOnEndRequest(object sender, EventArgs eventArgs)
{
var context = ((HttpApplication) sender).Context;
var filter = context.Items[FilterKey] as MemoryStreamFilter;
if (filter == null) return;
var jsonResponse = filter.ToString();
var xDocument = JsonConvert.DeserializeXNode(jsonResponse, "oauth");
var xmlResponse = xDocument.ToString(SaveOptions.DisableFormatting);
WriteResponse(context.Response, xmlResponse);
}
private static void WriteResponse(HttpResponse response, string xmlResponse)
{
response.Clear();
response.ContentType = "application/xml;charset=UTF-8";
response.Write(xmlResponse);
}
public void Dispose()
{
}
}
public class MemoryStreamFilter : Stream
{
private readonly Stream _stream;
private readonly MemoryStream _memoryStream = new MemoryStream();
public MemoryStreamFilter(Stream stream)
{
_stream = stream;
}
public override void Flush()
{
_stream.Flush();
}
public override int Read(byte[] buffer, int offset, int count)
{
return _stream.Read(buffer, offset, count);
}
public override void Write(byte[] buffer, int offset, int count)

_stream.Write(buffer, offset, count);

Ok I had such a fun time trying to figure this out using OWIN I thought I would share my solution with the community, I borrowed some insight from other posts https://stackoverflow.com/a/26216511/1148288 and https://stackoverflow.com/a/29105880/1148288 along with the concepts Alexei describs in his post. Nothing fancy doing with implementation but I had a requirement for my STS to return an XML formatted response, I wanted to keep with the paradigm of honoring the Accept header, so my end point would examine that to determine if it needed to run the XML swap or not. This is what I am current using:
private void ConfigureXMLResponseSwap(IAppBuilder app)
{
app.Use(async (context, next) =>
{
if (context.Request != null &&
context.Request.Headers != null &&
context.Request.Headers.ContainsKey("Accept") &&
context.Request.Headers.Get("Accept").Contains("xml"))
{
//Set a reference to the original body stream
using (var stream = context.Response.Body)
{
//New up and set the response body as a memory stream which implements the ability to read and set length
using (var buffer = new MemoryStream())
{
context.Response.Body = buffer;
//Allow other middlewares to process
await next.Invoke();
//On the way out, reset the buffer and read the response body into a string
buffer.Seek(0, SeekOrigin.Begin);
using (var reader = new StreamReader(buffer))
{
string responsebody = await reader.ReadToEndAsync();
//Using our responsebody string, parse out the XML and add a declaration
var xmlVersion = JsonConvert.DeserializeXNode(responsebody, "oauth");
xmlVersion.Declaration = new XDeclaration("1.0", "UTF-8", "yes");
//Convert the XML to a byte array
var bytes = Encoding.UTF8.GetBytes(xmlVersion.Declaration + xmlVersion.ToString());
//Clear the buffer bits and write out our new byte array
buffer.SetLength(0);
buffer.Write(bytes, 0, bytes.Length);
buffer.Seek(0, SeekOrigin.Begin);
//Set the content length to the new buffer length and the type to an xml type
context.Response.ContentLength = buffer.Length;
context.Response.ContentType = "application/xml;charset=UTF-8";
//Copy our memory stream buffer to the output stream for the client application
await buffer.CopyToAsync(stream);
}
}
}
}
else
await next.Invoke();
});
}
Of course you would then wire this up during startup config like so:
public void Configuration(IAppBuilder app)
{
HttpConfiguration httpConfig = new HttpConfiguration();
//Highly recommend this is first...
ConfigureXMLResponseSwap(app);
...more config stuff...
}
Hope that helps any other lost souls that find there way to the this post seeking to do something like this!
take a look here i hope it can help how to set a Web API REST service to always return XML not JSON
Could you retry by doing the following steps:
In the WebApiConfig.Register(), specify
config.Formatters.XmlFormatter.UseXmlSerializer = true;
var supportedMediaTypes = config.Formatters.XmlFormatter.SupportedMediaTypes;
if (supportedMediaTypes.Any(it => it.MediaType.IndexOf("application/xml", StringComparison.InvariantCultureIgnoreCase) >= 0) ==false)
{
supportedMediaTypes.Insert(0,new MediaTypeHeaderValue("application/xml"));
}
I normally just remove the XmlFormatter altogether.
// Remove the XML formatter
config.Formatters.Remove(config.Formatters.XmlFormatter);
Add the line above in your WebApiConfig class...
public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
// Web API configuration and services
// Configure Web API to use only bearer token authentication.
config.SuppressDefaultHostAuthentication();
config.Filters.Add(new HostAuthenticationFilter(OAuthDefaults.AuthenticationType));
// Web API routes
config.MapHttpAttributeRoutes();
// Remove the XML formatter
config.Formatters.Remove(config.Formatters.XmlFormatter);
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
}
}
I am having some troubles running an Xquery with Saxon9HE, which has a reference to an external module.
I would like Saxon to resolve the module with a relative path rather absolute.
the module declaration
module namespace common = "http://my-xquery-utils";
from the main xquery
import module namespace common = "http://my-xquery-utils" at "/home/myself/common.xquery";

}
System.out.print(transform(instance, args[1], args[2]));
}
public static String transform(XmlObject input, String xqFile, String xqParameter) {
String result = null;
try {

proc.getUnderlyingConfiguration().getOptimizer().setOptimizationLevel(0);
ctx = proc.getUnderlyingConfiguration().newStaticQueryContext();
ctx.setModuleURIResolver(new ModuleURIResolver() {
#Override

}
});
db = proc.newDocumentBuilder();

If a change it into a relative path like
import module namespace common = "http://my-xquery-utils" at "common.xquery";
I get

I am not sure how the ModuleURIResolver should be used.
Saxon questions are best asked on the Saxon forum at http://saxonica.plan.io - questions asked here will probably be noticed eventually but sometimes, like this time, they aren't our first priority.
The basic answer is that for the relative URI to resolve, the base URI needs to be known, which means that you need to ensure that the baseURI property in the XQueryCompiler is set. This happens automatically if you compile the query from a File, but not if you compile it from an InputStream.
If you don't know a suitable base URI to set, the alternative is to write a ModuleURIResolver, which could for example fetch the module by making another call on getResourceAsStream().
I'm trying to connect to SSH Unix server on button click (code written in actionPerformed() method). I'm using JSch for connecting to SSH server. The code is written in SwingWorker class as it is a network operation.
private void testConnectionButtonActionPerformed(java.awt.event.ActionEvent evt) {
SwingWorker<Boolean, Void> sw = new SwingWorker<Boolean, Void>(){
#Override
protected Boolean doInBackground() throws Exception {
JSch jsch = new JSch();
String host = "ServerHost";
String username = "username";
String password = "password";
Session session = jsch.getSession(username, host);
session.setPassword(password);
session.setTimeout(20000);
System.out.println("Connecting to server...");
session.connect();
return true;
}
#Override
public void done(){
try {
System.out.println(get().toString());
} catch (Exception ex) {
System.out.err(ex);
}
}
};
sw.execute();
}
But after running the with correct host, username and password details, I get the below error all the time:
com.jcraft.jsch.JSchException: timeout: socket is not established
at java.util.concurrent.FutureTask$Sync.innerGet(FutureTask.java:222)
at java.util.concurrent.FutureTask.get(FutureTask.java:83)
at javax.swing.SwingWorker.get(SwingWorker.java:583)
But whenever I run the same code in standalone program, I mean instead for writing actionPerformed() method, If I write it in normal method and calling from main() method. It will work. when I integrate the same code with Button Click's actionPerformed() method, it will give me above exception.
Can anyone suggest what I'm doing wrong here or any modification should be made to the code.
I tried to connect to SSH Server using "SSHJ" implementation, but I get the below error:

Can someone help me - how to move forward?
I took your code, wrapped it in some GUI code (and converted it to non-generics to be able to compile it with the same settings as the rest of the JSch examples). It works for me. Try this, and report what exception you get (it has a bit more exception logging).
