I am following following blog to click to call.
https://www.twilio.com/docs/tutorials/click-to-call-java-spring
I am able to place call and record too. But how can we store recording for each channel ?
Can someone please help.?
callCreator.setRecordingChannels("5"); or
callCreator.setRecordingChannels("dual");
does not help
Here is the complete class
public class TwilioLine {
private String twilioNumber;
private TwilioRestClient restClient;
public TwilioLine(TwilioRestClient restClient, String twilioNumber) {
this.restClient = restClient;
this.twilioNumber = twilioNumber;
}
public void call(final String phoneNumber, final String responseUrl) {
try {
CallCreator callCreator = new CallCreator(new PhoneNumber(phoneNumber), new PhoneNumber(twilioNumber), new URI(responseUrl));
callCreator.setRecord(true);
callCreator.setSendDigits("8245719056");
callCreator.setRecordingChannels("5");
callCreator.create(restClient);
} catch (URISyntaxException e) {
throw new CallException(e);
}
}

I have a record that performs a verification in its constructor as such :
public record Configuration(URI url) {
public Configuration(URI url) {
Validate.httpValid(url, "url");
}
}
Where the httpValid method is :
public static URI httpValid(final URI value, final String property) {
try {
value.toURL();
} catch (IllegalArgumentException | MalformedURLException e) {
throw new InvalidPropertyValueException(property, "httpValid", value, Map.of());
}
return value;
}
This however fails the test i'm trying to create :
#Test
void Should_RespectEqualsContract() {
EqualsVerifier
.forClass(Configuration.class)
.withPrefabValues(
Configuration.class,
new Configuration(URI.create("http://a.com")),
new Configuration(URI.create("http://b.com")))
.verify();
}
This is because EqualsVerifier is trying to create an object with "x" as argument :
InvalidPropertyValueException: The value x is not a valid httpValid as url
You're very close. You shouldn't provide the class that you're testing as a prefab value; instead you need to provide the paramter that's causing trouble, like this:
#Test
void Should_RespectEqualsContract() {
EqualsVerifier
.forClass(Configuration.class)
.withPrefabValues(
URI.class,
URI.create("http://a.com"),
URI.create("http://b.com"))
.verify();
}
I have two applications communicating with each other using rabbit.
I need to send (from app1) an object to a listener (in app2) and after some process (on listener) it answer me with another object, now I am receiving this error:
ClassNotFound
I am using this config for rabbit in both applications:
#Configuration
public class RabbitConfiguration {
public final static String EXCHANGE_NAME = "paymentExchange";
public final static String EVENT_ROUTING_KEY = "eventRoute";
public final static String PAYEMNT_ROUTING_KEY = "paymentRoute";
public final static String QUEUE_EVENT = EXCHANGE_NAME + "." + "event";
public final static String QUEUE_PAYMENT = EXCHANGE_NAME + "." + "payment";
public final static String QUEUE_CAPTURE = EXCHANGE_NAME + "." + "capture";
#Bean
public List<Declarable> ds() {
return queues(QUEUE_EVENT, QUEUE_PAYMENT);
}
#Autowired
private ConnectionFactory rabbitConnectionFactory;
#Bean
public AmqpAdmin amqpAdmin() {
return new RabbitAdmin(rabbitConnectionFactory);
}
#Bean
public DirectExchange exchange() {
return new DirectExchange(EXCHANGE_NAME);
}
#Bean
public RabbitTemplate rabbitTemplate() {
RabbitTemplate r = new RabbitTemplate(rabbitConnectionFactory);
r.setExchange(EXCHANGE_NAME);
r.setChannelTransacted(false);
r.setConnectionFactory(rabbitConnectionFactory);
r.setMessageConverter(jsonMessageConverter());
return r;
}
#Bean
public MessageConverter jsonMessageConverter() {
return new Jackson2JsonMessageConverter();
}
private List<Declarable> queues(String... nomes) {
List<Declarable> result = new ArrayList<>();
for (int i = 0; i < nomes.length; i++) {
result.add(newQueue(nomes[i]));
if (nomes[i].equals(QUEUE_EVENT))
result.add(makeBindingToQueue(nomes[i], EVENT_ROUTING_KEY));
else
result.add(makeBindingToQueue(nomes[i], PAYEMNT_ROUTING_KEY));
}
return result;
}
private static Binding makeBindingToQueue(String queueName, String route) {
return new Binding(queueName, DestinationType.QUEUE, EXCHANGE_NAME, route, null);
}
private static Queue newQueue(String nome) {
return new Queue(nome);
}
}
I send the message using this:
String response = (String) rabbitTemplate.convertSendAndReceive(RabbitConfiguration.EXCHANGE_NAME,
RabbitConfiguration.PAYEMNT_ROUTING_KEY, domainEvent);
And await for a response using a cast to the object.
This communication is between two different applications using the same rabbit server.
How can I solve this?
I expected rabbit convert the message to a json in the send operation and the same in the reply, so I've created the object to correspond to a json of reply.
Show, please, the configuration for the listener. You should be sure that ListenerContainer there is supplied with the Jackson2JsonMessageConverter as well to carry __TypeId__ header back with the reply.
Also see Spring AMQP JSON sample for some help.
Amazon provides a vast documentation, but there are so many docs that I'm lost, so here is my current service for upload/download files. Upload works as expected but on the download its where I have to download the files to a physical path and later serve the download to the user, I don't have much experience working with streams. Here is the FileManagerService class that connects to Amazon API.
using Amazon.S3;
using Amazon.S3.Model;
public class FileManagerService
{
public FileManagerService()
{
string serverPath = HttpContext.Current.Server.MapPath("~/");
string uploadPath = Path.Combine(serverPath, "FileUploads");
Directory.CreateDirectory(uploadPath);
UploadDirectory = uploadPath;
}
private string UploadDirectory { get; set; }
private docucloudEntities db = new docucloudEntities();
private IAmazonS3 S3Client = new AmazonS3Client();
private string S3Bucket = "bucketname";
public async Task<string> DownloadFile(string AmazonFileKey, string FileName)
{
var fileRequest = new GetObjectRequest
{
BucketName = S3Bucket,
Key = AmazonFileKey
};
var localRoute = Path.Combine(UploadDirectory, FileName);
using (var fileObject = await S3Client.GetObjectAsync(fileRequest))
{
if (fileObject.HttpStatusCode == HttpStatusCode.OK)
{
fileObject.WriteResponseStreamToFile(localRoute);
}
}
return localRoute;
}
}
This method returns the string, it's not complete yet with try catch blocks, but it currently works. Here is my controller method that download the file to the client:
public class FileManagerController : Controller
{
private FileManagerService FileService = new FileManagerService();
public async Task<ActionResult> DownloadFileAmazon(long FileId)
{
if (db.Archivos.Any(i => i.ArchivoID == FileId))
{
var archivo = db.Archivos.Single(i => i.ArchivoID == FileId);
var rutaarchivo = await FileService.DownloadFile(archivo.Ruta, archivo.Nombre);
if (System.IO.File.Exists(rutaarchivo))
{
var fileBytes = System.IO.File.ReadAllBytes(rutaarchivo);
var response = new FileContentResult(fileBytes, "application/octet-stream");
response.FileDownloadName = archivo.Nombre;
System.IO.File.Delete(rutaarchivo);
return response;
}else
{
return HttpNotFound();
}
}else
{
return HttpNotFound();
}
}
}
So here on the controller I read the file bytes and serve the download, after deleting the file, but this could lead to a slower perfomance, its there a way of achieving direct download.
As far as I can tell there is no reason to dispose GetObjectResponse (return type of GetObjectAsync) even if the docs says so. GetObjectResponse is not implementing IDisposable but is inheriting StreamResponse that is. However, as far as I can tell it's only disposing the ResponseStream. So you could return the stream from GetObjectResponse (fileObject.ResponseStream) together with the ContentTypefrom the headers (fileObject.Headers.ContentType) that you then can return as a file in your controller:
[HttpGet]
[Route("blob/{filename}")]
public async Task<IActionResult> GetFile(string filename)
{
try
{
var file = await _fileStorageService.GetBlobAsync(filename);
return File(file.Stream, file.ContentType);
}
catch (Exception ex)
{
// Handle exceptions
}
}
FileResult will dispose the stream after it has written the file so there the stream will finally get disposed.
I have an external dll written in C# and I studied from the assemblies documentation that it writes its debug messages to the Console using Console.WriteLine.
this DLL writes to console during my interaction with the UI of the Application, so i don't make DLL calls directly, but i would capture all console output , so i think i got to intialize in form load , then get that captured text later.
I would like to redirect all the output to a string variable.
I tried Console.SetOut, but its use to redirect to string is not easy.
As it seems like you want to catch the Console output in realtime, I figured out that you might create your own TextWriter implementation that fires an event whenever a Write or WriteLine happens on the Console.
The writer looks like this:
public class ConsoleWriterEventArgs : EventArgs
{
public string Value { get; private set; }
public ConsoleWriterEventArgs(string value)
{
Value = value;
}
}
public class ConsoleWriter : TextWriter
{
public override Encoding Encoding { get { return Encoding.UTF8; } }
public override void Write(string value)
{
if (WriteEvent != null) WriteEvent(this, new ConsoleWriterEventArgs(value));
base.Write(value);
}
public override void WriteLine(string value)
{
if (WriteLineEvent != null) WriteLineEvent(this, new ConsoleWriterEventArgs(value));
base.WriteLine(value);
}
public event EventHandler<ConsoleWriterEventArgs> WriteEvent;
public event EventHandler<ConsoleWriterEventArgs> WriteLineEvent;
}
If it's a WinForm app, you can setup the writer and consume its events in the Program.cs like this:
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
using (var consoleWriter = new ConsoleWriter())
{
consoleWriter.WriteEvent += consoleWriter_WriteEvent;
consoleWriter.WriteLineEvent += consoleWriter_WriteLineEvent;
Console.SetOut(consoleWriter);
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
static void consoleWriter_WriteLineEvent(object sender, Program.ConsoleWriterEventArgs e)
{
MessageBox.Show(e.Value, "WriteLine");
}
static void consoleWriter_WriteEvent(object sender, Program.ConsoleWriterEventArgs e)
{
MessageBox.Show(e.Value, "Write");
}
It basically amounts to the following:
var originalConsoleOut = Console.Out; // preserve the original stream
using(var writer = new StringWriter())
{
Console.SetOut(writer);
Console.WriteLine("some stuff"); // or make your DLL calls :)
writer.Flush(); // when you're done, make sure everything is written out
var myString = writer.GetStringBuilder().ToString();
}
Console.SetOut(originalConsoleOut); // restore Console.Out
So in your case you'd set this up before making calls to your third-party DLL.
You can also call SetOut with Console.OpenStandardOutput, this will restore the original output stream:
Console.SetOut(new StreamWriter(Console.OpenStandardOutput()));
Or you can wrap it up in a helper method that takes some code as an argument run it and returns the string that was printed. Notice how we gracefully handle exceptions.
public string RunCodeReturnConsoleOut(Action code)
{
string result;
var originalConsoleOut = Console.Out;
try
{
using (var writer = new StringWriter())
{
Console.SetOut(writer);
code();
writer.Flush();
result = writer.GetStringBuilder().ToString();
}
return result;
}
finally
{
Console.SetOut(originalConsoleOut);
}
}
Using solutions proposed by #Adam Lear and #Carlo V. Dango I created a helper class:
public sealed class RedirectConsole : IDisposable
{
private readonly Action<string> logFunction;
private readonly TextWriter oldOut = Console.Out;
private readonly StringWriter sw = new StringWriter();
public RedirectConsole(Action<string> logFunction)
{
this.logFunction = logFunction;
Console.SetOut(sw);
}
public void Dispose()
{
Console.SetOut(oldOut);
sw.Flush();
logFunction(sw.ToString());
sw.Dispose();
}
}
which can be used in the following way:
public static void MyWrite(string str)
{
// print console output to Log/Socket/File
}
public static void Main()
{
using(var r = new RedirectConsole(MyWrite)) {
Console.WriteLine("Message 1");
Console.WriteLine("Message 2");
}
// After the using section is finished,
// MyWrite will be called once with a string containing all messages,
// which has been written during the using section,
// separated by new line characters
}
Hi friends i am trying to read incoming sms but getting warning like this . Invocation of questionable method: java.lang.String.(String) found in: mypackage.MyApp$ListeningThread.run()
Here is my code is
public class MyApp extends UiApplication {
//private ListeningThread listener;
public static void main(String[] args) {
MyApp theApp = new MyApp();
theApp.enterEventDispatcher();
}
public MyApp() {
invokeAndWait(new Runnable() {
public void run() {
ListeningThread listener = new ListeningThread();
listener.start();
}
});
pushScreen(new MyScreen());
}
private static class ListeningThread extends Thread {
private boolean _stop = false;
private DatagramConnection _dc;
public synchronized void stop() {
_stop = true;
try {
_dc.close(); // Close the connection so the thread returns.
} catch (IOException e) {
System.err.println(e.toString());
}
}
public void run() {
try {
_dc = (DatagramConnection) Connector.open("sms://");
for (;;) {
if (_stop) {
return;
}
Datagram d = _dc.newDatagram(_dc.getMaximumLength());
_dc.receive(d);
String address = new String(d.getAddress());
String msg = new String(d.getData());
if(msg.startsWith("START")){
Dialog.alert("hello");
}
System.out.println("Message received: " + msg);
System.out.println("From: " + address);
System.exit(0);
}
} catch (IOException e) {
System.err.println(e.toString());
}
}
}
}
Please correct me where i am wrong.Is possible give me some code to read incoming sms content in blackberry.
A few points about your code:
That invokeAndWait call to launch a thread makes no sense. It doesn't harm, but is kind of waste. Use that method only to perform UI related operations.
You should try using "sms://:0" as param for Connector.open. According to the docs, a parameter with the form {protocol}://[{host}]:[{port}] will open the connection in client mode (which makes sense, since you are on the receiving part), whereas not including the host part will open it in server mode.
Finally, if you can't get it working, you could use instead the third method specified in this tutorial, which you probably have already read.
The error you quoted is complaining about the use of the String constructor that takes a string argument. Since strings are immutable in Java-ME, this is just a waste. You can use the argument string directly:
Invocation of questionable method: java.lang.String.(String) found in: mypackage.MyApp$ListeningThread.run()
//String address = new String(d.getAddress());
String address = d.getAddress();
// getData() returns a byte[], so this is a different constructor
// However, this leaves the character encoding unspecified, so it
// will default to cp1252, which may not be what you want
String msg = new String(d.getData());
