I have a simple test Web API that is up and working. When I run it and enter http://localhost:xxxxx/api/user in the browser it returns a JSON empty array and it has full functionality when I test it with Fiddler. But when I try and test it with the Chrome REST Console (with a GET Request to http://localhost:xxxxx/api/user) I get a "Connection Failed! Check your connectivity and try again" error.
Api Controller:
public class UserController : ApiController
{
private UserRepository repository = new UserRepository();
public int Put(int id, [FromBody]int amount)
{
var user = repository.GetByID(id);
if (user == null) return -1;
user.Total += amount;
repository.Save(user);
return user.Total;
}
public int Post([FromBody]CreateUserRequest request)
{
var user = new User { Goal = request.Goal, Name = request.Name, Total = 0 };
repository.Add(user);
return user.UserId;
}
public IEnumerable<User> Get() { return new List<User>(repository.GetAll()); }
public User Get(int id) { var user = repository.GetByID(id); return user; }
public class CreateUserRequest
{
public string Name { get; set; }
public int Goal { get; set; }
}
The REST Console had formerly worked with this test Web API. The only reference I could find on the web referenced un-signed certificates. I had created a signed certificate for localhost in IIS but I removed it, restarted the computer and the REST Console still returns the same error. Not that that should matter since the Web API is running in IIS Express. I have also tried it with other Web API's on my local machine and get the same error.
Does anyone have any idea as to the possible source of the problem or how I might troubleshoot it? As I said the Web API's are fully function when tested with Fiddler. The Web API was created with and is being ran from VS 2012 on a Windows 7 Ultimate workstation.
I subsequently noticed that when ever I ran an app from Visual Studio in Chrome that it would redirect to https (even for apps that were not using SSL) and generate an SSL error.
I cleared all browsing data in Chrome and both the Chrome and the REST Console problems cleared.

About 6 months ago I set up a web application in the google developers console so that employees of our internal web site could initiate emails which would read a template doc in a google account, merge some fields and then download a pdf version of it to email out.
Now we have to move those template docs to a different google managed domain/user account so I've made copies of the documents in the new account and updated our references with the new doc ids.
In addition, the email I had when I originally created this application in the google dev console is going away as of the first of the year. So I also have to recreate the app under a new account.
I've done that and matched all the settings of the original app. However, when I try to access a document I get the error Google.Apis.Auth.OAuth2.Responses.TokenResponseException: 'Error:"unauthorized_client", Description:"Unauthorized", Uri:""'
I had followed this page in setting up the original user authentication. I know there was a ton of trial and error before I actually got it working and I must be forgetting something. I'm wondering if it's tied to needing to reauthenticate the new app. Although I'm specifying the new clientid and clientsecret from the new app, I don't get the popup asking me to give permission to the app. I would expect with the new credential info that it would open that window asking me to give permission. Here's that file for reference. Any ideas?
public class AuthCallbackController : Google.Apis.Auth.OAuth2.Mvc.Controllers.AuthCallbackController
{
protected override FlowMetadata FlowData => new AppFlowMetadata();
}
public class AppFlowMetadata : FlowMetadata
{
private static readonly IAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = AwsSecrets.GoogleCreds.ClientId,
ClientSecret = AwsSecrets.GoogleCreds.ClientSecret
},
Scopes = new[] {DriveService.Scope.Drive},
DataStore = new FileDataStore("Drive.Api.Auth.Store")
});
public override IAuthorizationCodeFlow Flow => flow;
public override string GetUserId(Controller controller)
{
return "userid";
}
}
public class GoogleController : TECWareControllerBase
{
private readonly IGoogleCredentialService _gservice;
public GoogleController(IGoogleCredentialService gservice)
{
_gservice = gservice;
}
public async Task<ActionResult> IndexAsync(CancellationToken cancellationToken)
{
var result = await new AuthorizationCodeMvcApp(this, new AppFlowMetadata()).AuthorizeAsync(cancellationToken);
if (result.Credential != null)
{
_gservice.SaveRefreshToken(result.Credential.Token.RefreshToken);
return View();
}
return new RedirectResult(result.RedirectUri);
}
}
I finally found a way to get this working.
First off in this method
private static readonly IAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = AwsSecrets.GoogleCreds.ClientId,
ClientSecret = AwsSecrets.GoogleCreds.ClientSecret
},
Scopes = new[] {DriveService.Scope.Drive},
DataStore = new FileDataStore("Drive.Api.Auth.Store")
});
I had to change the FileDataStore("Drive.Api.Auth.Store") key to something else like FileDataStore("GoogleAuth")
That forced the authentication to fire up.
Unfortunately, google then complained about an invalid redirect uri. The following code returned a redirect uri of http://localhost:11224/AuthCallback/IndexAsync which didn't even exist in my web application's Authorized redirect uris. It should have been http://localhost:11224/MVC/AuthCallback/IndexAsync. So in the url result's redirect url I changed it to what it should have been which allowed me to complete the authorization. Now I can access the documents in the authenticated account.
var result = await new AuthorizationCodeMvcApp(this, new AppFlowMetadata()).AuthorizeAsync(cancellationToken);
I have an app running on Windows Phone 8.1 which calls a URL via InAppBrowser plugin. This URL is supposed to ask for the user certificate stored on a virtual smartcard on the phone.
When I call the URL via Internet Explorer, I am asked for my PIN to unlock the virtual smartcard but in the InAppBrowser, this doesn't work. No PIN prompt, nothing.
Iterating through the Certificates yielded from
IReadOnlyList<Certificate> certStores = await CertificateStores.FindAllAsync();
I can see the certificate at app runtime but InAppBrowser doesn't seem to query for them. Do I have to copy its reference to another certificate store or is InAppBrowser not capable of establishing SSL with user certificates ?
The issue is with the webview component, x-ms-webview to be more precisely. InAppBrowser plugin uses this component internally.
Found a workaround mentioned here, it kinda sounds like a security issue tbh so this could get fixed in the future but here are more details on said workaround:
Make a request to the URL which is supposed to trigger virtual smartcard unlock to access the user certificate, but with the HttpClient at native level (C#)
I've created another Windows Runtime Component in my solution which does a simple POST to the url I want to access from InAppBrowser later on.
While setting up the Windows.Web.Http.HttpClient, I fetch the user certificate from the smartcard and set it as HttpBaseProtocolFilter.ClientCertificate.
public sealed class SSLHelper
{
private static String errorMessage = "";
private static String statusMessage = "";
public static IAsyncOperation<Boolean> establishSSLConnection(String url)
{
return connect(url).AsAsyncOperation<Boolean>();
}
public static String getErrorMessage()
{
return SSLHelper.errorMessage;
}
public static String getStatusMessage()
{
return SSLHelper.statusMessage;
}
private static async Task<Boolean> connect(String urlString)
{
Certificate clientCert = await getCertificateAsync();
HttpBaseProtocolFilter filter = new HttpBaseProtocolFilter();
filter.ClientCertificate = clientCert;
HttpClient client = new HttpClient(filter);
try
{
System.Uri url = new System.Uri(urlString);
HttpResponseMessage response = await client.PostAsync(url, new HttpStringContent(""));
response.EnsureSuccessStatusCode();
SSLHelper.statusMessage = response.StatusCode.ToString();
return true;
}
catch (Exception e)
{
SSLHelper.errorMessage = e.ToString();
return false;
}
}
private static async Task<Certificate> getCertificateAsync()
{
CertificateQuery query = new CertificateQuery();
query.IssuerName = "Sample Issuer";
IReadOnlyList<Certificate> certStores = await CertificateStores.FindAllAsync(query);
return certStores.FirstOrDefault<Certificate>();
}
}
Make that code return as a promise on Javascript level and once it resolves, start the code which uses InAppBrowser to access the secure URL again. The native request causes the PIN prompt for virtual smartcard access, once you have entered the correct PIN, InAppBrowser / WebView can magically establish the connection.
There's a project called Web App Template (aka WAT - http://wat.codeplex.com/) that allows you to wrap a webapp as a Windows 8 / Windows Phone 8 application. I've done that to an app, now I'm trying to add the "rate my app" feature to it. I don't see where/if I can inject code for this component to be added.
I'm following a guide here: http://developer.nokia.com/community/wiki/Implement_%22Rate_My_App%22_in_under_60_seconds
I'm stuck at Step 5 - where do I add the Event Handler? There is no MainPage.xaml.cs and I don't see any similar files.
I imagine that WAT is calling another library to load a web browser. Is there some way I can inject an Event Handler and method into this library?
I suggest not to prompt the user with 'rate my app' thing in the first opening of the app as user should be given some time to see what the app looks like and how it functions. Therefore, keeping the number of app launches and asking to rate the app after some 5th - 10th launch of app will make more sense. Besides you should check if you already prompted the user to rate your app, if so never prompt again. (Otherwise you will piss them off with 'rate my app' thing)
In order to achieve this, you should at first keep the app launch count in app settings class.
The interface for storing any kind of setting:
public interface ISettingService
{
void Save();
void Save(string key, object value);
bool AddOrUpdateValue(string Key, object value);
bool IsExist(string key);
T Load<T>(string key);
T GetValueOrDefault<T>(string Key, T defaultValue);
}
The rating service class that consumes the above interface to store such count and settings:
public class RatingService
{
private const string IsAppRatedKeyName = "isApprated";
private const string TabViewCountKeyName = "tabViewCount";
private const bool IsAppratedDefault = false;
private const int TabViewCountDefault = 0;
private const int ShowRatingInEveryN = 7;
private readonly ISettingService _settingService;
[Dependency]
public RatingService(ISettingService settingService)
{
_settingService = settingService;
}
public void RateApp()
{
if (_settingService.AddOrUpdateValue(IsAppRatedKeyName, true))
_settingService.Save();
}
public bool IsNeedShowMessage()
{
return (_settingService.GetValueOrDefault(TabViewCountKeyName, TabViewCountDefault)%ShowRatingInEveryN) == 0;
}
public void IncreaseTabViewCount()
{
int tabCount = _settingService.GetValueOrDefault(TabViewCountKeyName, TabViewCountDefault);
if (_settingService.AddOrUpdateValue(TabViewCountKeyName, (tabCount + 1)))
_settingService.Save();
}
public bool IsAppRated()
{
return _settingService.GetValueOrDefault(IsAppRatedKeyName, IsAppratedDefault);
}
}
This is how you will run such functionality and prompt the user to rate the app (if previously not rated) anywhere in your project (mainpage or some other page where user launches some functionality):
private void RunRating()
{
if (!RatingService.IsAppRated() && RatingService.IsNeedShowMessage())
{
MessageBoxResult result = MessageBox.Show("Review the app?", "Would you like to review this awesome app?",
MessageBoxButton.OKCancel);
//show message.
if (result == MessageBoxResult.OK)
{
RatingService.RateApp();
new MarketplaceReviewTask().Show();
}
}
}
I'm a little bit new to all of these technologies so I'll try to be as clear as I can.
I'm writing a windows phone app that sends data in string format to a server:
public class sendDataControl
{
private string response = "";
public void sendToServer(string FullSTR)
{
try
{
WebClient webClient = new WebClient();
Uri uri = new Uri("http://pricequeryserver.azurewebsites.net/api/ReceiptDataService/?incomingdata=");
webClient.UploadStringAsync(uri,FullSTR);
webClient.UploadStringCompleted += new UploadStringCompletedEventHandler(webClient_UploadStringCompleted);
}
catch (Exception ex)
...
...
}
}
void webClient_UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)
{
if (e.Error != null)
{
responseXml=e.Error.Message;
MessageBox.Show(responseXml);
return;
}
else
{
responseXml = e.Result;
}
}
}
The server is an MVC4, basic, with api controller I added, that needs to get the data sent from the mobile.
As a test I'm just getting back a string that I send:
public class ReceiptDataServiceController : ApiController
{
private ReceiptContext db = new ReceiptContext();
...
...
public string GetDataFromMobile(string IncomingData)
{
return IncomingData;
}
}
While running the application I get an error via responseXml:
"The remote server returned an error: NotFound".
The server returns the right answer from all kinds of browsers, while on IIS and on the azure but not from the mobile emulator.
Any suggestions?
If you take a look at the documentation for UploadStringAsync overload you are using, you will notice that it sends data using POST method. While in your controller you have only implemented GET. And for your
You have to use other overload of UploadStringAsync, which lets you specify the HTTP VERB to use. And you must specify GET. Your client code should be converted to:
webClient.UploadStringAsync(uri,"GET", FullSTR);
And the best solution for simple GET operations like your is to actually use DownloadStringAsync:
var fullUri = new Uri("http://pricequeryserver.azurewebsites.net/api/ReceiptDataService/?incomingdata=" + FullStr);
webClient.DownloadStringAsync(fullUri);
Anyway, your question has nothing to do with Windows Azure, thus the removed tag.
Project: ASP MVC 4 running under .net 4.0 framework:
When running an application under VS 2010 express (or deployed and running under IIS 7.5 on my local machine) the following (pseudocode) result from an action works as expected
[HttpPost]
public ActionResult PostWord(Model model)
{
....
Response.StatusCode = 400;
Return new JsonResult { data = new {fieldName = "Word", error = "Not really a word!" } };
(and I have assigned ContentType and ContentEncoding properties of the JsonResult object, with no difference in behaviour)
When the deployable is moved onto a web host (using IIS 7), firebug is telling me that the response is as expected (400) but there is no JSON in the response (ie there is no text of any kind). If I remove the line
Response.StatusCode = 400;
from the action, the JSON is perfectly formed in the response, but of course the response status code is 200 (OK), which interferes with the consuming javascript and appropriate function call.
Any thoughts on what might be going on and how to fix this? Thank you
I had this exact same problem; in order to make sure that the correct answer is not buried in the comments (as it was for me), I want to reiterate #Sprockincat's comment:
For me at least, it was indeed an issue with IIS Custom errors, and can be solved with:
Response.TrySkipIisCustomErrors = true;
#Sprockincat - you should get credit for this. I'm just making it more visible because it's such a subtle fix to a problem that is quite difficult to diagnose.
I've created a subclass of JsonResult that allows you to specify the HttpStatusCode.
public class JsonResultWithHttpStatusCode : JsonResult
{
private int _statusCode;
private string _statusDescription;
public JsonResultWithHttpStatusCode(object data, HttpStatusCode status)
{
var code = Convert.ToInt32(status);
var description = HttpWorkerRequest.GetStatusDescription(code);
Init(data, code, description);
}
public JsonResultWithHttpStatusCode(object data, int code, string description)
{
Init(data, code, description);
}
private void Init(object data, int code, string description)
{
Data = data;
_statusCode = code;
_statusDescription = description;
}
public override void ExecuteResult(ControllerContext context)
{
context.HttpContext.Response.StatusCode = _statusCode;
context.HttpContext.Response.StatusDescription = _statusDescription;
base.ExecuteResult(context);
}
}
Then you can return this as your result and the status code will get set on the response. You can also test the status code on the result in your tests.
For anyone looking for this - in ASP.NET Core you can set the StatusCode property of JsonResult.
