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 />

<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.

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:
<configuration>
<system.diagnostics>

I migrated a web service to a WCF service. The service exposes two endpoints, one returns JSON and one returns SOAP.
The SOAP endpoint works as expected, but the response from the JSON endpoint is wrapped with the response object name - something that did not exist in the JSON response the web service I migrated from used to return.
I tried working with the BodyStyle property, but all I got is an exception: The body style 'Bare' is not supported by 'WebScriptEnablingBehavior'. Change the body style to be 'WrappedRequest'.
All my methods accept only POST requests.
This is how my service is configured:
<services>
<service name="MyService" behaviorConfiguration="MyServiceBehavior">
<endpoint address="" binding="basicHttpBinding" bindingNamespace="http://MyService.org/" contract="IMyService"/>
<endpoint address="json" behaviorConfiguration="JsonEndpointBehavior" binding="webHttpBinding" contract="IMyService" />

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.

I have a WCF service that is using https to communicate and json for the response format. I don't want my methods to be available to anyone so i change the authentication in IIS from anonymous & basic to just basic.
So far, the browser is asking for user and pass but i get the following error :
Could not find a base address that matches scheme http for the endpoint with binding WebHttpBinding. Registered base address schemes are [https].
What do i have to change to my endpoint to work with authentication ?

This config file solved my problem. I changed from basic to windows authentication, after i installed windows authentication in iis.
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.

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">
