I am trying to get back a profile for myself but I only get back a successful http response...no data. This is the code I am using.
try {
RestClient restClient = new RestClient("https://apps.na.collabserv.com","my.email","my.password");
Response<AtomFeed> responseFeed = restClient.doGet("/profiles/atom/profileService.do").asAtomFeed();
System.out.println(responseFeed.getData().toXmlString());
} catch(Exception e) {
e.printStackTrace();
}
If I try to add a email= to the url I get a 403 forbidden return.
Not really sure what the issue is,
Thanks!

I am using Azure CosmosDB with Blazor WebAssembly (client-side).
I want to catch CosmosException When connection token expires, But not getting cosmos exception for that, (Null exception found)
I have also tried same code in console application, In that I am able to catch cosmos exception that showing token expired.
Code sample :
using (CosmosClient client = new CosmosClient(account, token))
{
Database db = null;
db = client.GetDatabase("databaseName");
Container orgContainer = client.GetContainer("databaseName","containerName");
try
{
ItemResponse<CosmosException> response = await orgContainer.ReadItemAsync<CosmosException>("test", new PartitionKey("test"));
var data = response.Resource;
}
catch(CosmosException ex)
{
}
catch(Exception ex)
{
}
}
Exception Details of Console Application
This is probably because the exception occurs outside the try block. Also, make sure you do not instantiate a new cosmos client on each request. This does not perform well. Use singleton and keep alive between requests.
I'm using IMobileServiceSyncTable from Azure Mobile App. In InsertAsync operation, on the backend server side, I had some validations for the data and, if that validations failure, I want throw Exception from the server side. I tried return InternalServerError(), throw HttpResponseException, but never worked on the client side. I debbuged the Post method in server side, the server throws the exception or return InternalServerError, but in the mobile client, don't occurs error.
Can anyone help me?
Here is my code on the client side:
public async Task<bool> AddPaciente(Paciente novoPaciente)
{
//other things
try
{
await _pacienteTable.InsertAsync(novoPaciente);
}
catch (Exception e)
{
Debug.WriteLine(e.Message);
Debug.WriteLine(e.StackTrace);
throw new WebException(AppResources.MensagemFalhaConexaoServidorAzure);
}
await SyncPaciente();
return true;
}
Here is my post method on the backend server side
// POST tables/Paciente
public async Task<IHttpActionResult> PostPaciente(Paciente novoPaciente)
{
//other things
if (paciente != null)
{
var responseMessage = new HttpResponseMessage(HttpStatusCode.BadRequest)
{
Content = new StringContent("Já existe um paciente com esse token cadastrado.")
};
//throw new HttpResponseException(responseMessage);
return InternalServerError(new Exception("Já existe um paciente com esse token cadastrado."));
}
}
You should listen to the response status code.
var response = await _pacienteTable.InsertAsync(novoPaciente);
if (response.IsSuccessStatusCode) {
var content = await response.Content.ReadAsStringAsync ();
}
else
{
//Here handle the error code
throw new WebException(AppResources.MensagemFalhaConexaoServidorAzure);
}
I'm using IMobileServiceSyncTable from Azure Mobile App. In InsertAsync operation, on the backend server side, I had some validations for the data and, if that validations failure, I want throw Exception from the server side.
For IMobileServiceSyncTable, you are dealing with An Offline Client which means that IMobileServiceSyncTable<T>.InsertAsync would directly insert data into the local SQLite store on your mobile client-side. Until you manually call MobileServiceClient.SyncContext.PushAsync(), then your local data store would be pushed to your mobile backend. For this approach, I would recommend you make sure that you need to validate the inputs before you saving them into the local data store, otherwise your push operations would fail, then you need to force your client user to adjust the existing inputs even after it has been successfully added before.
If you use An Online Client as follows, then both your approaches for throwing the exception would be immediately returned to your client.
var mobileClient= new MobileServiceClient("https://{your-mobile-app-name}.azurewebsites.net");
var _pacienteTable= mobileClient.GetTable<Paciente>();
await _pacienteTable.InsertAsync(novoPaciente);
Moreover, I used the following code line for catching the exception:
try
{
await table.InsertAsync(item);
}
catch (MobileServiceInvalidOperationException ex)
{
//TODO:
//await ex.Response.Content.ReadAsStringAsync(); //get detailed response content
}
catch (Exception e)
{
//TODO: other uncaught exception
}
Also, for the similar issue, you could leverage Fiddler to capture the network traces to narrow down this issue, make sure your client-side could correctly receive the relevant response.
I'm working with Azure App Service .NET backend with a Xamarin.iOS app. I am able to successfully register a new user and I can see the user's details in the database. I have a custom ApiController, which handles the registration and the I'm able to save the details with a successful POST call.
However, when I try to log into the app, I get the following error:
{Microsoft.WindowsAzure.MobileServices.MobileServiceInvalidOperationException: The request could not be completed. (Method Not Allowed)
Below is my code:
The RegistrationController in the backend which successfully makes a POST call
[MobileAppController]
[RoutePrefix("api/register")]
[AllowAnonymous]
public class RegisterController : ApiController
{
[HttpPost]
[Route("newuser")]
public HttpResponseMessage NewUser(RegistrationRequest request)
{
// Registration code in here
}
}
This is how I call this function on the client side:
public async Task<Result<UserProfile>> RegisterUser(RegistrationWrapper registrationrequest)
{
try
{
var registrationRequest = new JObject();
registrationRequest.Add("username", registrationrequest.username);
registrationRequest.Add("password", registrationrequest.password);
registrationRequest.Add("email", registrationrequest.email);
registrationRequest.Add("phone", registrationrequest.phone);
registrationRequest.Add("firstname", registrationrequest.firstname);
registrationRequest.Add("lastname", registrationrequest.lastname);
var result = await client.InvokeApiAsync("register/newuser", registrationRequest);
// Handle result here
}
catch (Exception ex)
{
return Result<UserProfile>.Failure(ex.Message + ex.StackTrace + ex.InnerException);
}
}
Custom AuthController which handles the login
This POST call fails with the error described above.
[MobileAppController]
[RoutePrefix("api/auth")]
public class AuthController : ApiController
{
public HttpResponseMessage Post(AuthenticationRequest credentials)
{
try
{
//Authentication code goes here
catch (Exception e)
{
Console.WriteLine("Ërror :" + e.Message);
Console.WriteLine(e.StackTrace);
return Request.CreateResponse(HttpStatusCode.InternalServerError, new
{
Stacktrace = e.StackTrace,
ErrorMessage = e.Message,
Credentials = credentials
});
}
}
How I invoke this function from the client side
async Task<Result<Account>> Login(string username, string password)
{
try
{
var credentials = new JObject();
credentials.Add("username", username);
credentials.Add("password", password);
var result = await client.InvokeApiAsync("auth", credentials);
//Handle result here
}
catch (Exception ex)
{
return Result<Account>.Failure(ex, ex.Message + ex.StackTrace);
}
}
}
I'm not sure why it's failing during the log in. Any ideas?
After trying tons of solutions found here on StackOverflow, the one that finally worked for me was this first answer found on a similar question.
It seems that the http POST call is redirected to https.
After enabling authentication on your App Service in the Azure portal, you need to change the url to https.
So I changed mine from this:
http//{my_site}.azurewebsites.net
To this:
https//{my_site}.azurewebsites.net
On the client side, and now used this new one to create my local sync tables.
Everything works as expected now.
The HTTP status code 405 is returned when an API endpoint is called with a wrong (Not Allowed) HTTP method. For example, if instead of a POST request the endpoint is called with a GET request.
I'm using Volley to send an http post request with parameters from my android app to my local server running in http://192.168.1.4:3000/battery_signal_report
I'm pretty sure the server is running properly (I checked it with Postman successfully).
also, I successfully sent the request through Android Studio's Emulator using ip 10.0.2.2
Trying to make it work, i used various request implementations including JsonObjectRequest, StringRequest and the custom request described here: Volley JsonObjectRequest Post request not working
Also, I've read somewhere that Volley post requests have some problems with the request header, so i tried to override it in different ways.
Nothing works. onErrorResponse is called every time with an empty VolleyError input.
I've fairly new to android development, so any insights would be much appreciated.
Thanks in advance.
For anyone else coming across this, you need to forget about the header override and setup your own getBodyContentType() and getBody() methods. Follow this pattern:
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, successListener, errorListener) {
#Override
public String getBodyContentType() {
return "application/json; charset=utf-8";//set here instead
}
#Override
public byte[] getBody() {
try {
Map<String, String> params = yourObject.getMappedParams();
JSONObject json = new JSONObject(params);
String requestBody = json.toString();
return requestBody == null ? null : requestBody.getBytes("utf-8");
} catch (UnsupportedEncodingException uee) {
return null;
}
}
};
We use keycloak API in our application. When we try to retrieve the Client list of the realm it pass 403 forbidden error. Highly appreciate your comments for avoid this matter.
String authServer = UriUtils.getOrigin(httpRequest.getRequestURL().toString()) + AUTH_CONTEXT_PATH;
String token = httpRequest.getHeader("Authorization").replaceAll("Bearer ", "");
String realmClientsUrl = authServer+"/admin/realms/testrealm/clients/"+getClientRepresentationId(authServer,realm,token);
ClientRequest request = getClientRequest(realmClientsUrl,token);
ClientResponse<String> response;
ClientRepresentation clientRepresentation = null;
try{
response = request.get(String.class);
validateResponse(response,"CLIENT_REPRESENTATION");
clientRepresentation = response.getEntity(ClientRepresentation.class);
return clientRepresentation;
} catch (Exception e) {
e.printStackTrace();
}
Error which passed,
java.lang.Exception: ErrorStage:CLIENT_REPRESENTATION_ID,HTTP responseCode:403,StatusIno=Forbidden
You might get this error if the logged in user doesn't have the relevant Client Roles access. Add the client role access as "View Client" under realm-management.
