WCF and JSON binding - json

I am trying to create a wcf service that returns json. I have some problems with my config file and i also don't know how to test it.
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="false" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="ContactLibraryJSON.ContactLibrary">
<endpoint address="" binding="webHttpBinding" bindingConfiguration="JSONEndpointBehavior"
contract="ContactLibraryJSON.IContactServiceJSON" />
<endpoint address="mex" binding="mexHttpBinding" bindingConfiguration=""
contract="IMetadataExchange" />
<host>
<baseAddresses>
<add baseAddress="http://192.168.1.31/ContactLibraryJSON" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="JSONEndpointBehavior">
<webHttp/>
</behavior>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="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"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
I still get
"Cannot add the behavior extension webhttp to the service behavior
names JSONEndpointBehavior because the underlying behavior type does
not implement the IServiceBehaviorInterface"
Contact is defined like :
[DataContract(Name="Contact")]
public class Contact
{
[DataMember(Name="FirstName")]
public string firstName=null;
[DataMember(Name="LastName")]
public string lastName=null;
[DataMember(Name="Email")]
public string email=null;
[DataMember(Name = "Age")]
public int age = 0;
[DataMember(Name = "Street")]
public string street=null;
[DataMember(Name = "City")]
public string city=null;
[DataMember(Name = "Country")]
public string country=null;
}
IContactService is defined like :
[ServiceContract]
public interface IContactServiceJSON
{
[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, UriTemplate = "")]
Contact GetContact();
}
The implementation of GetContact:
public Contact GetContact()
{
return new Contact()
{
firstName = "primulNume",
lastName = "alDoileaNume",
age = 33,
city = "Cluj",
country = "Romania",
email = "ceva#mail.com",
street = "Bizusa 8"
};
}
My service runs on another computer in my lan. Base address is like: http://192.168.1.xxx/ContactLibraryService. ContactLibraryService is hosted by IIS and is converted to an application.

You need to add the <webHttp/> to the list of endpoint behaviors. Also, the endpoint needs to use the webHttpBinding. And finally, to respond to GET HTTP requests, you need to use the WebGet attribute (instead of WebInvoke(Method="GET").
<system.serviceModel>
<services>
<service name="ContactLibrary.ContactLibrary">
<endpoint address=""
binding="webHttpBinding"
behaviorConfiguration="JSONEndpointBehavior"
contract="ContactLibrary.IContact"/>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
<endpoint address="ws"
binding="wsHttpBinding"
bindingConfiguration=""
contract="ContactLibrary.IContact" />
<host>
<baseAddresses>
<add baseAddress="http://localhost/ContactLibrary" />
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="JSONEndpointBehavior">
<webHttp/>
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information,
set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="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"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
And the service contract:
[ServiceContract]
public interface IContact
{
[OperationContract]
[WebGet(BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json, UriTemplate = "contact")]
Contact GetContact(int idContact);
}

It's not good that you have Service Contract IContact and Data Contact Contact. Rename Service Contract like IContactService.
<services>
<service name="ContactLibrary.ContactService">
<endpoint address="" binding="webHttpBinding" contract="ContactLibrary.IContactService" behaviorConfiguration="JsonBehavior" />
<host>
<baseAddresses>
<add baseAddress="http://localhost:8732"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="JsonBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
During Debug time (it looks you have WCF library), service address will be http://localhost:8732/contact

I think you missed bindings here you have to add webHttpBinding and basichttpbing under the bindings tab in system.serviceModel tag.
<services>
<service name="VInfotech.Server.Intranet.IntranetService" behaviorConfiguration="IntranetService.Service1Behavior">

When i debugged ,GetCustomData() returns list. but when i check it on browser returns nothing.. no error information. please help me
Please configure WCF Message logging and use svctraceviewer tool to see the actual error that probably is happening behind the scenes:

WCF service Post error on IIS 6

I have developed a REST service that used to run localy on my PC and had no issues!!I have hosted my wcf on a windows server 2008-r2 IIS 7.5, in order to call my service from an IP. I am using the get method with a JSON and all works fine, but when i try the post( with chrome plugin) i get 405 error and 500 error. I checked the MIME-TYPES and added json for IIS. Any solution or suggestiong how to resolve this error would be very useful.
I will post my webconfig and ISERVICE files as well.

public bool CheckIfExists(UrlObject urlObject)
{
string link= urlObject.url;
//Standard logon to CRM procedure(Framework)
if abc=true
return true;

WCF oData Insert via Web Service

I am trying to increase maxReceivedMessageSize for my wcf odata service. I have an another web service which is posting values to my wcf service to insert values to sql. I am posting
{
A:1,
B:1,
C:3,
D:4,
}
this raised an error. The remote server returned an error: (400) Bad Request. If i post the value below, it inserted successfully.
{
A:1
}
so can somebody please help me how to fix this error please? There are examples on the web which are trying to modify web config like below but they dont suits me because i dont have a service contract.

WCF Json GET Service: Check that the sender and receiver's EndpointAddresses agree

I've been working in .NET for a while now, but I'm new to WCF. I'm trying to create my very first WCF service using JSON. I thought I would start really, really simple and then build from there. But I have somehow managed to screw up even the most simple of services. Here's what I've got so far.
Web.Config:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<services>
<service name="MarathonInfo.MarathonInfoService">
<endpoint address="http://localhost:10298/MarathonInfoService.svc" binding="webHttpBinding" contract="MarathonInfo.IMarathonInfo" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="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="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
Then, in the service file:
namespace MarathonInfo
{
public class MarathonInfoService : IMarathonInfo
{
public String GetData()
{
return "Hello World";
}
}
}
And in the interface:
namespace MarathonInfo
{
[ServiceContract]
public interface IMarathonInfo
{
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "/GetData", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
String GetData();
}
}
So, when I go to this url:
http://localhost:10298/MarathonInfoService.svc/GetData
I get this error:
The message with To
'http://localhost:10298/MarathonInfoService.svc/GetData' cannot be
processed at the receiver, due to an AddressFilter mismatch at the
EndpointDispatcher. Check that the sender and receiver's
EndpointAddresses agree.
I am able to execute the service just fine through Visual Studio in debug mode. But in the browser, I only get that error.
What am I doing wrong?
Thanks!

If you want to create a WCF WebHTTP Endpoint (i.e., one which returns JSON, and uses the [WebGet] / [WebInvoke] attributes), the endpoint needs to have the <webHttp/> behavior associated with it.
<system.serviceModel>
<services>
<service name="MarathonInfo.MarathonInfoService">
<endpoint address="http://localhost:10298/MarathonInfoService.svc"
binding="webHttpBinding"
contract="MarathonInfo.IMarathonInfo"
behaviorConfiguration="Web"/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="Web">
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="false" />
</system.serviceModel>

WCF service with JSONP over SSL

We have a SSL configured website that hosts a WCF-service. The service's binding has crossDomainScriptAccessEnabled="true" and communication is serialized using JSON.
When we request this service from http it returns JSONP but when it is requested using HTTPS it returns just JSON. I need to have JSONP in either way, please help.
Current configuration is like this:
<webHttpBinding>
<binding name="webHttpBindingWithJsonP" crossDomainScriptAccessEnabled="true" />
</webHttpBinding>
<behaviors>
<serviceBehaviors>
<behavior name="JsonServiceBehaviors">
<serviceMetadata httpGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
<endpointBehaviors><behavior name="webHttpBehavior">
<webHttp />
</behavior></endpointBehaviors>
</behaviors>
<services>
<service name="Backend.CIService" behaviorConfiguration="JsonServiceBehaviors">
<endpoint address="" binding="webHttpBinding"
bindingConfiguration="webHttpBindingWithJsonP" contract="Backend.ICIService"
behaviorConfiguration="webHttpBehavior"/>
</service></services>
What happens if you use this configuration:
<webHttpBinding>
<binding name="jsonp" crossDomainScriptAccessEnabled="true" />
<binding name="jsonpSsl" crossDomainScriptAccessEnabled="true">
<security mode="Transport" />
</binding>
</webHttpBinding>
<behaviors>
<serviceBehaviors>
<behavior name="JsonServiceBehaviors">
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="webHttpBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
<services>
<service name="Backend.CIService" behaviorConfiguration="JsonServiceBehaviors">
<endpoint address="" binding="webHttpBinding"
bindingConfiguration="jsonp" contract="Backend.ICIService"
behaviorConfiguration="webHttpBehavior"/>
<endpoint address="" binding="webHttpBinding"
bindingConfiguration="jsonpSsl" contract="Backend.ICIService"
behaviorConfiguration="webHttpBehavior"/>
</service>
</services>
The problem is that if you want to call service over both HTTP and HTTPS you must provide two endpoints - one for HTTP and one for HTTPS.
