401 Unauthorized Error

I have been assigned the task of researching the feasibility of using SiteFinity as a CMS for our current site's marketing department. I am testing things with the sample code I received from:

www.sitefinity.com/.../getting_started_with_restful_services_in_sitefinity

When I run the code and give it the login information I get a 401 Unauthorized error.

This is running with IISExpress.

How do I get around this?

Hello Michael,

I think the referenced example is a bit outdated. You can refer to this example in GitHub in order to connect to Sitefinity properly. Note that you must select Claims authentication in order to connect successfully.

I home this information is helpful. Do not hesitate to get back to us.

Thanks for the updated code, but I see some problems with the sample code you recently provided.

 1. It does not actually validate that the authentication was successful:

private void Login_button_Click(object sender, EventArgs e)
          

            //set the credentials
            string sfUrl = this.url.Text;
            string username = this.username.Text;
            string password = this.password.Text;

            helper.SignIn(username, password, sfUrl);
                        
            DisableLogin();
            
       

The above simply makes the auth request and then enables the other buttons. 

2. I do not think auth is working STILL because when I click the button "List data" I get an error:

An unhandled exception of type 'System.Runtime.Serialization.SerializationException' occurred in System.Runtime.Serialization.dll

This code causes that error: NewsItems rolesData = (NewsItems)rolesSerializer.ReadObject(ms);

 It appears that the object is empty which means auth failed.

I am going to try a few things, but do you have any further tips?

Hello,

You can take a look at the second part of this blog post describing in details how this works with Claims Authentication used in the later Sitefinity versions:Working with RESTful Services Part 2 – Claims Authentication and Designing Service Calls.

OK, so I can see that authentication works when I click the LOGIN on the sample application. However, what I have a problem with now is when I click on the button labelled "LIST DATA" I get an exception. Here is the code:

 private void ListNewsButtonClick(object sender, EventArgs e)
       

            //Listing the roles
            string rolesResult = null;

            helper.CallService(ServiceHelper.NewsUrl, null, "GET", out rolesResult, "application/json");

            using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(rolesResult)))
           
                DataContractJsonSerializer rolesSerializer = new DataContractJsonSerializer(typeof(NewsItems));

                NewsItems rolesData = (NewsItems)rolesSerializer.ReadObject(ms); <--- this line causes a n exception

                foreach (NewsItem item in rolesData.Items)
               
                    NewsList.Items.Add(item);

               

              

           

  

       

The execption is system.runtime.serialization.serializationexception

How do I get over this hurdle?

Hello,

I have tested the GitHub sample and I was not able to reproduce the error, video is attached. I would like to suggest opening a ticket for this issue so I can get more information regarding the exact scenario so I can investigate further.
