Question

I have a Drupal Views 2 view that returns a number of fields for some nodes as JSON. I can view it in Chrome, and it has everything I expect.

When I download it on my Windows Phone 7 app, one field, “field_images_nid” is mysteriously missing from the response. What could have caused this? Does Drupal not send that field because of some user agent data on WP7’s WebClient?

        WebClient data = new WebClient();
        data.DownloadStringCompleted += new DownloadStringCompletedEventHandler(onComplete);
        data.DownloadStringAsync(new Uri(dataUri));

The field in question is a link to an image associated with the node. Views refers to it as “Content: Images Full Node”.

Update: I made a new test app that does nothing but make the request so I can view the result in a debugger:

public partial class MainPage : PhoneApplicationPage
{
    public MainPage()
    {
        InitializeComponent();

        Loaded += new RoutedEventHandler(MainPage_Loaded);
    }

    void MainPage_Loaded(object sender, RoutedEventArgs e)
    {
        WebClient client = new WebClient();
        client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(client_DownloadStringCompleted);
        client.DownloadStringAsync(new Uri("http://path/to/service"));
    }

    void client_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        string result = e.Result;
    }
}

I made a new view that does nothing but return “Title” and “Content: Images (full node)” for a given nid. I am able to observe the same incongruence between the Chrome and WP7 request.

Update 2: When I go to the views url in Chrome incognito, the field is not returned. Perhaps there is a permissions issue at work? I thought the field should be anonymously available.

Turns out the problem was server side. When I was testing it in my browser, I was always logged in. Making the content type available anonymously solved the issue.
