I am creating a GraphClient using the following code:
private IGraphServiceClient getGraphClientByClientCredentialGrant(Logger aLogger, String anAuthority,
String anApplicationId, String aSecret, String aScope) throws LambdaLibraryException {
ConfidentialClientApplication app = ConfidentialClientApplication.builder(
anApplicationId,
ClientCredentialFactory.createFromSecret(aSecret))
.authority(anAuthority)
.build();
ClientCredentialParameters clientCredentialParam = ClientCredentialParameters.builder(
Collections.singleton(aScope))
.build();
CompletableFuture future = app.acquireToken(clientCredentialParam);
String myAccessToken = future.get().accessToken();
theAuthProvider = new SimpleAuthProvider(myAccessToken);
DefaultLogger myLogger = new DefaultLogger();
myLogger.setLoggingLevel(LoggerLevel.ERROR);
IGraphServiceClient myClient = GraphServiceClient.builder()
.authenticationProvider(theAuthProvider)
.logger(myLogger)
.buildClient();
return myClient;
}
This works fine using version 1.9.1 of the SDK. However if I use version 2.9.0 I get the following error:
Method execution failed:
java.lang.NoSuchMethodError: 'com.microsoft.aad.msal4j.ClientApplicationBase$Builder com.microsoft.aad.msal4j.ConfidentialClientApplication$Builder.authority(java.lang.String)'
All this test is doing is calling the above method with the required parameters to create a new client. I'm guessing that I have missed a changing in the interim releases, but looking at the MS documentation, I can't see what I need to change.

Can anyone help me with Azure notification hub, how to set up device installation form c# code. I have problem with the Installation object. How to set it to pass it as parameter to CreateOrUpdateInstallation method of hub client instance. It's not clear to me.
I have a hub on azure that works with device registration like charm in local, but uploaded on azure are not working. Now I wanna try with istalation.
thnx
update: after 4 days, I figured out, that you can't send notification to yourself. Azure somehow knows that you are sending notification to yours phone, and that's why my welcome message never delivered to my phone.
update: this is how now I install the device i my backend code:
[HttpGet]
[Route("api/push/test-installation")]
public async Task<IActionResult> NotificationInstalationTest()
{
string connectionString = "{{my connection string}}";
string hubName = "{{my hub name}}";
string token = "{{tokne}}";
NotificationHubClient hubClient = NotificationHubClient.CreateClientFromConnectionString(connectionString, hubName);
string notificationText = $"Test message for Azure delivery for Atila at: {DateTime.Now.ToShortTimeString()}";
var alert = new JObject
(
new JProperty("aps", new JObject(new JProperty("alert", notificationText))),
new JProperty("inAppMessage", notificationText)
).ToString(Newtonsoft.Json.Formatting.None);
IList<string> tags = new List<string>();
tags.Add("email");
IDictionary<string, string> pushVariables = new Dictionary<string, string>();
pushVariables.Add( "email", "atila#panonicit.com" );
Installation installation = new Installation();
installation.InstallationId = Guid.NewGuid().ToString();
installation.Platform = NotificationPlatform.Apns;
installation.PushChannel = token;
installation.Tags = tags;
installation.PushVariables = pushVariables;
await hubClient.CreateOrUpdateInstallationAsync(installation);
NotificationOutcome result = await hubClient.SendAppleNativeNotificationAsync(alert);
return Ok("Success");
}
Now when I hit this endpoint with Postman it works, if the same endpoint call comes from iOS it not works!
thnx
How to set it to pass it as parameter to CreateOrUpdateInstallation method of hub client instance. It's not clear to me.
Based on my understanding, you are registering the notification hub from your backend using the installation model. For your WebAPI project, assuming your method for create/update an installation as follows:
InstallationController.cs
//PUT api/installation
public async Task<HttpResponseMessage> Put(DeviceInstallation deviceUpdate)
{
Installation installation = new Installation();
installation.InstallationId = deviceUpdate.InstallationId;
//TODO:
await hub.CreateOrUpdateInstallationAsync(installation);
return Request.CreateResponse(HttpStatusCode.OK);
}
For your mobile client, you could refer to the following method:
private async Task<HttpStatusCode> CreateOrUpdateInstallationAsync(DeviceInstallation deviceInstallation)
{
using (var httpClient = new HttpClient())
{
//TODO: set your authorization header
//httpClient.DefaultRequestHeaders.Authorization
var putUri =$"{your-backend-endpoint}/api/installation";
string json = JsonConvert.SerializeObject(deviceInstallation);
var response = await httpClient.PutAsync(putUri, new StringContent(json, Encoding.UTF8, "application/json"));
return response.StatusCode;
}
}
Moreover, for more details you could refer to Registration management and here for building backend with the registration model to build your backend using the installation model.
I am new to IOS platform. I have a code snippet written using JAVA API.
AmazonECS amazonECS = new AmazonECSClient(credentials).withRegion(usWest1);
String command="bash /opt/run-task.sh "+"/mnt/s3/inputFile1::/mnt/s3/inputFile2"+" "+ "outputFile";
ContainerOverride containerOverrides = new ContainerOverride().withCommand(command).withName("<<container name>>");
TaskOverride overrides = new TaskOverride().withContainerOverrides(containerOverrides);
RunTaskRequest runTaskRequest = new RunTaskRequest().withCluster("<<cluster name>>").withTaskDefinition("<<task definition arn>>")
.withOverrides(overrides).withGeneralProgressListener(new ProgressListener() {
#Override
public void progressChanged(ProgressEvent progressEvent) {
System.out.println(progressEvent.getBytesTransferred());
System.out.println(progressEvent.getEventType());
}
});
Task task = new Task().withTaskDefinitionArn("<<task definition arn>>")
.withOverrides(overrides);
RunTaskResult runTaskResult = amazonECS.runTask(runTaskRequest).withTasks(task);
List<Failure> failures = runTaskResult.withTasks(task).getFailures();
I am using ffmpeg to merge few video files as single file. I need to know if there is equivalent functionality available in IOS.
Below is the java sample code from worklight to invoke adapter.
public static void testAdapterCall(){
try{
DataAccessService service = WorklightBundles.getInstance().getDataAccessService();
String paramArray = "[5, 3,]";
ProcedureQName procedureQname = new ProcedureQName("CalculatorAdapter", "addTwoIntegers");
InvocationResult result = service.invokeProcedure(procedureQname, paramArray);
}
catch(Exception e)
{
e.printStackTrace();
}
}
I'm getting a Null Pointer exception, when it goes to line
DataAccessService service = WorklightBundles.getInstance().getDataAccessService();
Log is as below:
java.lang.NullPointerException
at com.worklight.customcode.Calculator1.testAdapterCall(Calculator1.java:38)
at com.worklight.customcode.Calculator1.main(Calculator1.java:53)
Versions:
Java 1.7
Worklight 6.2
The Adapter is deployed, and the server is also running locally.
I saw this question in other sites also, but it is not answered.
Any help is highly appreciated.
See the documentation in the following PDF document, starting page #13.
public void callProcedure() {
DataAccessService service = worklightBundles.getInstance().getDataAccessService();
String paramArray = "['param1', 'param2', 'param3']";
ProcedureQName procedureQName = new ProcedureQName("adapterName",
"procedureName");
InvocationResult result = service.invokeProcedure(ProcedureQName,
paramArray);
JSONObject jsonObject = result.toJSON();
String value = (String)jsonObject.get("key");
}
Be sure to add any missing includes once you enter the code into a Java IDE, such as Eclipse.
I am accessing Rackspace Cloud APIs.
I have one api call which authenticates me on the rackspace cloud.
The method works perfectly, however, from time to time, i get this exception, randomly :
The remote name could not be resolved: 'identity.api.rackspacecloud.com'
When i am not getting this exception, the method returns the expected result, as it should be.
Is there any specific reason why it does this?
Here is my .net code:
private async Task<XDocument> AuthenticateAsync()
{
XNamespace ns = "http://docs.rackspace.com/identity/api/ext/RAX-KSKEY/v1.0";
XDocument doc =
new XDocument(
new XDeclaration("1.0", "UTF-8", "Yes"),
new XElement("auth",
new XElement(ns + "apiKeyCredentials",
new XAttribute("username", "the userName"),
new XAttribute("apiKey", "the apiKey")
)
)
);
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
StringContent content = new StringContent(doc.ToString(), Encoding.UTF8, "application/xml");
// i randomly get "The remote name could not be resolved" exception
HttpResponseMessage response = await client.PostAsync("https://identity.api.rackspacecloud.com/v2.0/tokens", content);
response.EnsureSuccessStatusCode();
string stringResponse = await response.Content.ReadAsStringAsync();
return XDocument.Parse(stringResponse);
}
}
This certainly sounds like a DNS failure. Can you configure your machine to use the Google DNS servers and try again?
I am trying to generate the OData Proxy for the service : http://services.odata.org/Northwind/Northwind.svc/$metadata
I am using System.Data.Services.Design.EntityClassGenerator for generating the OData proxy.
When I instantiate the EntityClassGenerator and call GenerateCode the output has no errors. But there is no code in the generated proxy code.
The same code works for my own service. But when I point it to any external service the EntityClassGenerator is not working.
Here is the code :
HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.Create(metadataEndpoint);
webRequest.Method = "GET";
webRequest.ContentType = "text/xml;encoding='utf-8";
webRequest.Proxy = (proxy != null) ? proxy : WebRequest.DefaultWebProxy;
using (WebResponse response = webRequest.GetResponse())
{
string xml = string.Empty;
XmlReaderSettings settings = new XmlReaderSettings();
using (TextReader reader = new StreamReader(response.GetResponseStream()))
{
xml = reader.ReadToEnd();
using (XmlTextReader sourceReader = new XmlTextReader(reader))
{
using (StringWriter targetWriter = new StringWriter())
{
// Generate the OData End point proxy.
EntityClassGenerator entityGenerator = new EntityClassGenerator(LanguageOption.GenerateCSharpCode);
entityGenerator.OnPropertyGenerated += new EventHandler<PropertyGeneratedEventArgs>(entityGenerator_OnPropertyGenerated);
IList<System.Data.Metadata.Edm.EdmSchemaError> errors = entityGenerator.GenerateCode(sourceReader, targetWriter, namespacename);
entityGenerator.OnPropertyGenerated -= new EventHandler<PropertyGeneratedEventArgs>(entityGenerator_OnPropertyGenerated);
odataProxyCode = targetWriter.ToString();
}
}
}
}
I found the code in the question to be a useful starting point for doing exactly what the OP was asking. So even though the OP doesn't accept answers, I'll describe the changes I made to get it to work in case it is useful to someone else.
Removed the xml = reader.ReadToEnd(); call. I assume that was for debugging purposes to look at the response from the web request, but it had the result of "emptying" the reader object of the response. That meant that there was nothing left in the reader for the GenerateCode call.
The important one: Changed the use of EntityClassGenerator to System.Data.Services.Design.EntityClassGenerator. In the code below, I included the entire name space for clarity and specificity. Based on the code in the question, it appears the OP was probably using System.Data.Entity.Design.EntityClassGenerator. I used .NET Reflector to examine datasvcutil.exe, which is a command-line utility that can generate the proxy classes. I saw that it referenced the generator in that other name space.
For figuring out the problems, I dumped the errors from the GenerateCode call. One could examine them in the debugger, but some kind of automated checking of them would be needed regardless.
Here is what I ended up with:
HttpWebRequest webRequest = (HttpWebRequest)HttpWebRequest.
Create("http://services.odata.org/Northwind/Northwind.svc/$metadata");
webRequest.Method = "GET";
webRequest.ContentType = "text/xml;encoding='utf-8";
webRequest.Proxy = WebRequest.DefaultWebProxy;
using (WebResponse response = webRequest.GetResponse())
{
using (TextReader reader = new StreamReader(response.GetResponseStream()))
{
using (XmlTextReader sourceReader = new XmlTextReader(reader))
{
using (StringWriter targetWriter = new StringWriter())
{
// Generate the OData End point proxy.
System.Data.Services.Design.EntityClassGenerator entityGenerator =
new System.Data.Services.Design.EntityClassGenerator(
System.Data.Services.Design.LanguageOption.GenerateCSharpCode);
IList<System.Data.Metadata.Edm.EdmSchemaError> errors =
entityGenerator.GenerateCode(sourceReader, targetWriter,
"My.Model.Entities");
foreach (System.Data.Metadata.Edm.EdmSchemaError error in errors)
Console.WriteLine("{0}: {1}", error.Severity.ToString(), error.Message);
string odataProxyCode = targetWriter.ToString();
}
}
}
}
