UNABLE to POST data to WCF from Android - c#

I'm trying to send data to WCF service from an Android Application but somehow the service doesn't seems to be call through the android. I received a STATUSCODE value = 500 through adnroid in LOGCAT (which means the Internal Server Error) I go through the source code 100 times but didn't figure out the Bug. and almost checked all the posts related to my problem but still didn't get any solution.
HERE IS THS CODE
Android Code:
private class sendPostData extends AsyncTask<String, Void, String>
{
#Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
HttpPost request = new HttpPost( LOGIN_SERVICE_URL + "/MyCar");
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
JSONStringer getCarInfo;
try {
getCarInfo = new JSONStringer()
.object()
.key("myCar")
.object()
.key("Name").value(edt_carName.getText().toString())
.key("Make").value(edt_carMake.getText().toString())
.key("Model").value(edt_carModel.getText().toString())
.endObject()
.endObject();
StringEntity entity = new StringEntity(getCarInfo.toString());
request.setEntity(entity);
// Send request to WCF service
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(request);
Log.d("WebInvoke", "Saving : " + response.getStatusLine().getStatusCode());
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(String result) {
txt_verif.setText("Success");
}
}
everything is working fine in android code except calling the WCF service. I Debug the code several times and received statuscode = 500
HERE is the WCF Service
Service.cs
public class Service1 : IService1
{
public void UpdateMyCar(myCar myCar) {
string strConnectionString = ConfigurationManager.ConnectionStrings["Database1"].ConnectionString;
SqlConnection conn = new SqlConnection(strConnectionString);
conn.Open();
using (SqlCommand cmd = new SqlCommand("Insert into TestingTable (Name,Make,Model) Values (#Name,#Make,#Model)", conn)) {
cmd.Parameters.AddWithValue("#Name", myCar.Name);
cmd.Parameters.AddWithValue("#Make", myCar.Make);
cmd.Parameters.AddWithValue("#Model", myCar.Model);
int queryResult = cmd.ExecuteNonQuery();
} conn.Close();
}
LogCat

this service is also publish on IIS. and I also checked that service with google chrome extension SIMPLE REST CLIENT and received an internal server error

The problem is your host name doesn't match what you are using from the phone.
You can turn off address filter to fix this temporarily:
[ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]
public class Service1 : IService1
{
....
}
But you should fix the hostname when you release to production

Create a domain in your machine with proper port number and make sure you are able to call the service using the Google's Rest client.If it works,then you won't find any issue if you call the same using your android phone.
Following article will help to setup virtual directory with proper port number.[http://www.hosting.com/support/iis7/create-new-sites-in-iis-7/]
Note you can't call localhost directly from your mobile.atleast try to call the service with ipaddress.[http://localhost/service/mycar] =>[http://DemoService/service/mycar]

The following code will help you to debug your code a little bit deep.
catch (Exception ex)
{
WebException webexception = (WebException)ex;
var responseresult = webexception.Response as HttpWebResponse;
//Code to debug Http Response
var responseStream = webexception.Response.GetResponseStream();
string fault_message = string.Empty;
int lastNum = 0;
do
{
lastNum = responseStream.ReadByte();
fault_message += (char)lastNum;
} while (lastNum != -1);
responseStream.Close();
}

Never mind, I have made several changes in web.config file and got the solution. <endpointBehaviors> tag was missing in my case and several other things. here is the updated code of web.config file.

WCF REST Service - HTTP 404 error while execution

I am using WCF REST service with basic authentication(UserName / Password) in IIS.
My interface - ICustomer.cs is as below:

Also, please let me know if it is the correct binding I'm using for obtaining Basic Authentication.

WCF Service fails when accessing host registry

I've been working on a wrapper for an API that will let me access it via a web service. The wrapper is a WCF service that I'm using to interface between the API and an asmx.
API---WCF---Webservice
Currently, I can get the API to work with the wrapper and the wrapper to communicate with the web service. However, any calls I make that originate from the web service to the API fail. The line that causes the failure is one that accesses a registry key on the host. My guess is that this is somehow permission related, but I'm new to C# and web services so I don't know for sure.
If it is permission related, where/how can I give the client permission to access the host's registry?
WFC code:

string result = "THE SERVICE IS WORKING BORK BORK\n";
int handle = 1234;
double retVal = -1;

Running wcf service without App.config doesn't work

I create simple wcf host in console application. It doesn't work and the exception make NO SENSE:/
The exception looks really wierd:
"ContractDescription 'IFooService' has zero operations; a contract
must have at least one operation."
because, here is the code and i I have an operation:
[ServiceContract]
public interface IFooService
{
[OperationContract]
void DoNothing();
[OperationContract]
int GetFoo(int i);
}
public class FooService : IFooService
{
public void DoNothing()
{
}
public int GetFoo(int i)
{
return i + 1;
}
}
class Program
{
static void Main(string[] args)
{
try
{
string address = "http://localhost:9003/FooService";
Uri addressBase = new Uri(address);
var svcHost = new ServiceHost(typeof(FooService), addressBase);
BasicHttpBinding bHttp = new BasicHttpBinding();
Type contractType = typeof(IFooService);
ContractDescription contractDescription = new ContractDescription(contractType.Name);
contractDescription.ProtectionLevel = ProtectionLevel.None;
contractDescription.ContractType = contractType;
contractDescription.ConfigurationName = contractType.FullName;
contractDescription.SessionMode = SessionMode.NotAllowed;
svcHost.AddServiceEndpoint(new ServiceEndpoint(contractDescription, bHttp, new EndpointAddress(address)));
svcHost.Open();
Console.WriteLine("\n\nService is Running as >> " + address);
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
Console.ReadKey();
}
}
This is basically entire code. App.config is left untouched:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
</startup>
</configuration>
EDIT: A little clue, this way it works: I didn't change service or contract, but moved configuration to App.config, so changed only Main method:
App.config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
</startup>

<endpoint address="http://localhost:9003/FooService" binding="basicHttpBinding"
contract="WcfDemos.ConsoleHost.IFooService" />
</service>
</services>
</system.serviceModel>
</configuration>
Main:
static void Main(string[] args)
{
try
{
string address = "http://localhost:9003/FooService";
Uri addressBase = new Uri(address);
var svcHost = new ServiceHost(typeof(FooService), addressBase);
svcHost.Open();
Console.WriteLine("\n\nService is Running as >> " + address);
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
Console.ReadKey();
}
Why do you need to use the ContractDescription? I suppose it looks for the settings in the configuration file.
You may do the following (use the AddServiceEndpoint method without ContractDescription):
static void Main(string[] args)
{
try
{
string address = "http://localhost:9003/FooService";
Uri addressBase = new Uri(address);
var svcHost = new ServiceHost(typeof(FooService), addressBase);
BasicHttpBinding bHttp = new BasicHttpBinding();
//Type contractType = typeof(IFooService);
//ContractDescription contractDescription = new ContractDescription(contractType.Name);
//contractDescription.ProtectionLevel = ProtectionLevel.None;
//contractDescription.ContractType = contractType;
//contractDescription.ConfigurationName = contractType.FullName;
//contractDescription.SessionMode = SessionMode.NotAllowed;
//svcHost.AddServiceEndpoint(new ServiceEndpoint(contractDescription, bHttp, new EndpointAddress(address)));
svcHost.AddServiceEndpoint(typeof(IFooService).ToString(), bHttp, address);
svcHost.Open();
Console.WriteLine("\n\nService is Running as >> " + address);
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
Console.ReadKey();
}
BTW here you may find some library for configuring your WCF services without app.config files: WCF NetTcpBinding Bootcamp
I believe you have to add an endpoint to the ServiceHost if you don't provide the endpoints in the config file. See the AddServiceEndpoint call:
Uri baseAddr = new Uri("http://localhost:8000/WCFService1");
ServiceHost localHost = new ServiceHost(typeof(CalculatorService), baseAddr);
try
{
localHost.AddServiceEndpoint(typeof(ICalculator), new WSHttpBinding(), "CalculatorService");
ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
smb.HttpGetEnabled = true;
localHost.Description.Behaviors.Add(smb);
localHost.Open();
Console.WriteLine("Service initialized.");
Console.WriteLine("Press the ENTER key to terminate service.");
Console.WriteLine();
Console.ReadLine();
localHost.Close();
}
catch (CommunicationException ex)
{
Console.WriteLine("Oops! Exception: {0}", ex.Message);
localHost.Abort();
}
http://www.programminghelp.com/dotnet/wcf-creating-and-implementing-a-service-in-c/
The above comes from Microsoft example:

which is a great place to start. Nonetheless ... it is still unclear what needs to be added in code to make the app.config content below redundant:

POST Request empty in REST service

I've experimented with my own REST service as a WCF service, but I am having problems when I try to POST to the service from a client.
Here is the Service code:
[ServiceContract]
public interface IBookService
{
[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "AddBook/")]
string AddBook(HttpRequestMessage request);
}
public class BookService : IBookService
{
static IBookRepository repository = new BookRepository();
public string AddBook(HttpRequestMessage request)
{
try
{
// request is always empty.
var content = request.Content;
Book tempBook = JsonConvert.DeserializeObject<Book>(content.ReadAsStringAsync().Result);
repository.AddNewBook(tempBook);
}
catch (Exception ex)
{
//
}
return "AddBookTest";
}
}
Here is the client code:
var client = new HttpClient();
var url = new Uri("http://localhost:53258/");
client.BaseAddress = url;
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var tempBook = new Book() { BookId = 10, Title = "Title", ISBN = "123143234"};
var serializedBook = JsonConvert.SerializeObject(tempBook);
HttpContent content = new StringContent(serializedBook, Encoding.UTF8, "application/json");
var postResponse = _client.PostAsync("AddBook/", content).Result;
if (!postResponse.IsSuccessStatusCode)
// Always returns 400 Bad request.
The POST calls the AddBook method, but the HttpRequestMessage object is always empty:
I've researched for hours now, yet I can't come up with another relatively simple solution.
Any kind souls that can help me figure out what I am missing?

This answer did the trick.
I had already tried something similar, but I must've missed something along the way.
https://stackoverflow.com/a/6836030/4063668
I ended up with this declaration in my interface:
[OperationContract]
[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "AddBook/", BodyStyle = WebMessageBodyStyle.Bare)]
string AddBook(Book request);

How to use HTTPS with WCF SessionMode.Required - simplest possible example

UPDATE (8/7/2014) - The solution to this problem was that I needed to add a class that derived from "UserNamePasswordValidator" and register it in Web.Config.
I have created a simple test WCF service and test console client application (see below for code). I am using .NET 4.5.1. I have already searched for duplicates on StackOverflow (found similar posts here and here) - however I feel that the referenced posts are potentially outdated, and also feel that my post is more limited in scope.
OK now for the example:
The solution currently uses sessions (in ITestService.cs):
[ServiceContract(SessionMode = SessionMode.Required)]
... and uses wsHttpBinding (see below app.config and web.config).
When I deploy this to a server, I am successfully able to access it via a web browser using HTTPS like this: https://myserver.com/test/testservice.svc
However, when I change the endpoint in the client app.config from:
http://localhost:20616/TestService.svc/TestService.svc
to:
https://myserver.com/test/testservice.svc
and run the console application again, I receive the error: "The provided URI scheme 'https' is invalid; expected 'http'. Parameter name: via"
My question is, what is the minimum changes I need to make for this to work, without changing SessionMode.Required?
Here is the client console application code. Please be sure to change the App.Config value for "mycomputer\Matt" to the correct value for your machine.
Program.cs
using System;
namespace TestClient
{
class Program
{
static void Main(string[] args)
{
Console.Clear();
Console.WriteLine("Attempting to log in...");
try
{
TestServiceReference.TestServiceClient client = new TestServiceReference.TestServiceClient();
bool loginSuccess = client.LogIn("admin", "password");
if (loginSuccess)
{
Console.WriteLine("Successfully logged in.");
string secretMessage = client.GetSecretData();
Console.WriteLine("Retrieved secret message: " + secretMessage);
}
else
{
Console.WriteLine("Log in failed!");
}
}
catch (Exception exc)
{
Console.WriteLine("Exception occurred: " + exc.Message);

Console.WriteLine("Press ENTER to quit.");
Console.ReadLine();

{
IsAuthenticated = true;
return true;
}
else

bool ITestService.LogOut()

string ITestService.GetSecretData()

The solution to this problem was that I needed to add a class that derived from "UserNamePasswordValidator" and register it in Web.Config.
public class CustomUserNameValidator : UserNamePasswordValidator
{
public override void Validate(string userName, string password)
{
return;
}
}
Web.config:
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the values below to false before deployment -->
<serviceMetadata httpsGetEnabled="true" />
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true" />
<serviceCredentials>
<userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="MyProgram.CustomUserNameValidator,MyProgram" />
</serviceCredentials>
</behavior>
</serviceBehaviors>
</behaviors>
