Can't add user photo

[markgerlach]

I can't seem to add a user photo. I get the user, and then I run this code:

// Find the file we're looking for
string targetFile = @"EmpPhoto.jpg";

ZenFile file = new ZenFile();
file.ContentType = "image/jpeg";
file.FileData = File.ReadAllBytes(targetFile);
file.FileName = "EmpPhoto.jpg";
var uploadedFile = api.Attachments.UploadAttachment(file);
string url = uploadedFile.Attachments[0].ContentUrl;

Photo ph = new Photo();
ph.Id = uploadedFile.Attachments[0].Id;
ph.ContentType = uploadedFile.Attachments[0].ContentType;
ph.ContentUrl = url;
ph.Size = (int)new FileInfo(targetFile).Length;
ph.Name = "EmpPhoto.jpg";

// Create a thumbnail
Thumbnail nail = new Thumbnail();
nail.ContentType = ph.ContentType;
nail.ContentUrl = ph.ContentUrl;
nail.Size = ph.Size;
nail.Id = ph.Id;

user.RemotePhotoUrl = ph.ContentUrl;
user.Photo = ph;

IndividualUserResponse userResponse = api.Users.UpdateUser(user);

The user object has the photo on my side, but the response user doesn't have a photo set. What am I doing wrong? BTW - the photo is up on the site - I can browse to the URL.

Thanks,
Mark

I'd like to second this - I'm trying to sync user details from Active Directory to Zendesk and this is the last bit I can't finish.

Well, until we can get a response, I wrote the following bit of code today that seems to work. Drop me a line if you have any questions. Create a class with just this in it and then call the method as a static instance:

public class UserPhoto
    {
        protected static string GetPasswordOrTokenAuthHeader()
        {
            // Email contains my email address, Token contains that long string Zendesk gave me
            return GetAuthHeader(ZendeskHelper.EMail + "/token", ZendeskHelper.Token);
        }

        protected static string GetAuthHeader(string userName, string password)
        {
            string auth = Convert.ToBase64String(Encoding.UTF8.GetBytes(string.Format("{0}:{1}", userName, password)));
            return string.Format("Basic {0}", auth);
        }

        /// <summary>
        /// Set the user's photo to the attached file
        /// </summary>
        /// <param name="id">The ID of the user</param>
        /// <param name="filePath">The file to set.  If left blank, the photo will be removed</param>
        /// <returns>True if successful - otherwise false</returns>
        public static bool SetUserPhoto(long id, string filePath)
        {
            bool rtv = true;

            try
            {
                /// ZendeskHelper.URL = "https://{yoursite}.zendesk.com/api/v2"
                var requestUrl = ZendeskHelper.URL + string.Format("/users/{0}.json", id);
                HttpWebRequest req = WebRequest.Create(requestUrl) as HttpWebRequest;
                string boundaryString = "FEF3F395A90B452BB8BFDC878DDBD152";
                req.ContentType = "multipart/form-data; boundary=" + boundaryString;

                req.Headers["Authorization"] = GetPasswordOrTokenAuthHeader();
                req.PreAuthenticate = true;

                req.Method = "PUT";
                req.Accept = "application/json, application/xml, text/json, text/x-json, text/javascript, text/xml";

                // Use a MemoryStream to form the post data request,
                // so that we can get the content-length attribute.
                MemoryStream postDataStream = new MemoryStream();
                StreamWriter postDataWriter = new StreamWriter(postDataStream);

                // Include the file in the post data
                postDataWriter.Write("\r\n--" + boundaryString + "\r\n");
                if (!String.IsNullOrEmpty(filePath))
                {
                    FileInfo info = new FileInfo(filePath);     // Get some info on the file
                    postDataWriter.Write("Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n"
                                            + "Content-Type: image/jpeg\r\n\r\n",
                                            "user[photo][uploaded_data]",
                                            info.Name);

                    postDataWriter.Flush();

                    // Read the file
                    FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
                    byte[] buffer = new byte[1024];
                    int bytesRead = 0;
                    while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
                    {
                        postDataStream.Write(buffer, 0, bytesRead);
                    }
                    fileStream.Close();
                }
                else
                {
                    postDataWriter.Write("Content-Disposition: form-data; name=\"{0}\"; \r\n\r\n" 
                                            + "",
                                            "user[photo][uploaded_data]");
                }
                postDataWriter.Write("\r\n--" + boundaryString + "--\r\n");
                postDataWriter.Flush();

                // Set the http request body content length
                req.ContentLength = postDataStream.Length;

                // Dump the post data from the memory stream to the request stream
                Stream s = req.GetRequestStream();

                postDataStream.WriteTo(s);

                postDataStream.Close();

                var res = req.GetResponse();
                var response = res as HttpWebResponse;
                string responseFromServer = string.Empty;
                using (var responseStream = response.GetResponseStream())
                {
                    using (var reader = new StreamReader(responseStream))
                    {
                        responseFromServer = reader.ReadToEnd();
                    }
                }

                if (!String.IsNullOrEmpty(responseFromServer))
                {
                    rtv = ((String.IsNullOrEmpty(filePath) &&
                        responseFromServer.ToLower().Contains("\"photo\":null")) ||
                        (!String.IsNullOrEmpty(filePath) &&
                        !responseFromServer.ToLower().Contains("\"photo\":null")));
                }
            }
            catch (Exception ex)
            {
                rtv = false;
                throw ex;
            }

            return rtv;
        }
    }

    internal static class StringExtensions
    {
        internal static bool IsNullOrWhiteSpace(this string value)
        {

            // this is needed because .net 3.5 and older don't have 
            // string.IsNullOrWhiteSpace
            if (value == null) return true;

            for (int i = 0; i < value.Length; i++)
            {
                if (!char.IsWhiteSpace(value[i])) return false;
            }

            return true;
        }
    }

You can call it like this to put the photo in. The user is the User object you got back from the API.

UserPhoto.SetUserPhoto(user.Id.Value, targetFile);

Or like this to blank out the photo:

UserPhoto.SetUserPhoto(user.Id.Value, string.Empty);

Hey, that’s great! I’ve done a brief read through and it’s just what I need, will apply this ASAP.

Thanks so much for your help!
