Provide information about Modifier to Metadata

[danielkornev]

Since July 2014, Dropbox Core API supports Modifier data for files in personal accounts. This is available only to those apps that requested permission for that, but this is a very, very useful feature.

For now, I used the following approach:

1. own method to obtain metadata
2. own class with metadata
3. method:

private async Task GetMetadataEx(string relativePath)
{
string webFilePath = relativePath.Replace("", "/");

        HttpClientHandler handler = new HttpClientHandler();

        // OAuth
        DropNetRT.Authentication.OAuthMessageHandler oauthHandler =
            new DropNetRT.Authentication.OAuthMessageHandler(handler, apiKey, apiSecret, client.UserLogin.Token, client.UserLogin.Secret);

        HttpClient c = new HttpClient(oauthHandler);

        string str = string.Format("https://api.dropbox.com/1/metadata/auto/{0}", webFilePath);

        HttpRequest httpRequest = new HttpRequest(HttpMethod.Get, str);

        // we don't need list
        httpRequest.Parameters.Add(new HttpParameter("list", (object)false));
        //httpRequest.Parameters.Add(new HttpParameter("include_deleted", (object)includeDeleted));

        // we need membership data
        httpRequest.Parameters.Add(new HttpParameter("include_membership", (object)true));

        HttpResponseMessage httpResponseMessage;
        oauthHandler.Authenticate(httpRequest);
        try
        {
            httpResponseMessage = await c.SendAsync(httpRequest);
        }
        catch (Exception exception)
        {
            //throw new DropboxException(exception);

            return null;
        }
        if (httpResponseMessage.StatusCode != HttpStatusCode.OK)
        {
            return null;
            //throw new DropboxException(httpResponseMessage);
        }

        string responseString = await httpResponseMessage.Content.ReadAsStringAsync();


        var metadataEx = JsonConvert.DeserializeObject<DropboxMetadataEx>(responseString);

        return metadataEx;
    }

1. extended metadata class:

   public class DropboxMetadataEx : DropNetRT.Models.Metadata
   

   {
   [JsonProperty("modifier")]
   public Modifier Modifier
   {
   get;
   set;
   }

   } // class

   public class Modifier
   {
   [JsonProperty("display_name")]
   public string DisplayName { get; set; }
   [JsonProperty("uid")]
   public string Uid { get; set; }
   } // class

Heads up: The following fields relating to shared folders are in production beta. Please complete this form for access.

...

modifier
For files within a shared folder, this field specifies which user last modified this file. The value is a user dictionary with the fields uid (user ID), display_name, and, if the linked account is a member of a Dropbox for Business team, same_team (whether the user is on the same team as the linked account). If this endpoint is called by a Dropbox for Business app and the user is on that team, a member_id field will also be present in the user dictionary. If the modifying user no longer exists, the value will be null.

Thanks, I'll take a look at adding this to the existing GetMetadata function with an additional flag.

Do you know if it errors without permission or just doesn't return the modifier details?

No idea, actually, Damian. I was busy crafting prototype for demo purposes, and thus didn't check that.
