Hello Jon,

I am getting this same error, did you manage to solve this issue?

Best Regards

Looks like it, yes - CreateValidationToken() method below will return null if user is not authenticated.

httpContext.Response.Headers[aspNetAntiForgery.HeaderName] = aspNetAntiForgery.CreateValidationToken();

I would call this a bug.

Hello Mari,

Thanks for your debugging help, I just registered an "incident". Will follow up in this thread as soon as I get a response back.

Cheers,

Hello,

The response from the EPiServer Support Team:

"Unfortunately you can't use REST data anonymously and if you want to do that, you have to use WebAPI a standard thing from Microsoft."

ASP. NET Web API is pretty straightforward as well, specially if you are already developing a ASP. NET MVC site. If the site is based on WebForms, the following link would help:

http://www.asp.net/web-api/overview/creating-web-apis/using-web-api-with-aspnet-web-forms

If your responses need to be in JSON, one alternative would be the following:

Hi,

I am working on EPiserver CMs 7 Rest service as per the article:http://world.episerver.com/Documentation/Items/Developers-Guide/EPiServer-Framework/7/User-Interface/Setting-Up-a-REST-Data-Store/ and http://bergdaniel.se/creating-a-rest-data-store-in-episerver-7-preview.

I am getting an error "value can not be null" when i am anonymous.

Server Error in '/' Application. Value cannot be null.
Parameter name: value Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Also when accessing the restservice with login the Json response starts with "{}&&" thus making the response data not getting validated.

Can anyone provide any inputs on how to access EPiserver rest service anonymously and how to parse the Json response starting with "{}&&".

Any help will be highly appreciated.

Thanks

Gunjan

The EPiServer REST stores are to be used for user interface functions only and these require that you are authenticated. If you want to use this for the public site, we recommend that you use Web.API instead.
