attempting to fetch images of a private unlisted group wiki page via API

We tried the following case:

case 1 : we had created a plugin , tried 

Apis.Get<IUsers>().RunAsUser(RunAsUserID, () =>
				{
				
			image = Image.GetInstance(src);
				});

case 2:

using Rest sdk

var         adminKey = String.Format("{0}:{1}", "8nobz9x7io5b4r4d", "abcd");
			var adminKeyBase64 = Convert.ToBase64String(Encoding.UTF8.GetBytes(adminKey));
			string imageurl = "http://devcommunity.name.com/resized-image/__size/320x240/__key/communityserver-wikis-components-files/00-00-00-00-04/google.png";
			using (var client = new WebClient())
				{
					client.Headers.Add("Rest-User-Token", adminKeyBase64);
					byte[] imageBytes = client.DownloadData(imageurl);
					var data = imageBytes;
					var imagearray = Convert.ToBase64String(data);
					var dataUrl = "data:image/png;base64," + imagearray;
				}

For both the cases it throws error as follows:

NVelocity.Exception.MethodInvocationException: Invocation of method 'imageinstances' in  GetImagesOfWikis threw exception System.Net.WebException : The remote server returned an error: (403) Forbidden. ---> System.Net.WebException: The remote server returned an error: (403) Forbidden.
   at System.Net.HttpWebRequest.GetResponse()

It works fine for all Group Types Except Private Listed & Private Unlisted.

Instead of attempting to use the url directly you probably need to break it down and use the Cfs endpoint:  https://community.telligent.com/community/10/w/api-documentation/61480/show-cfs-rest-endpoint

Filestore: communityserver-wikis-components-files

path:  00-00-00-00-04

file: google.png

If those do not work replace the dashes (-) with periods (.)

Hi,

We tried  above case  but it throws an exception like

Telligent.Evolution.RestSDK.Exceptions.JsonParseError: 'ReadTo could not find value (") started at (0).'

Telligent.Evolution.RestSDK.Exceptions.JsonBadFormat: 'Json contains invalid format.'

we tried as follows

var host = new ClientCredentialsRestHost("username", "http://devcommunity.sample.com/", "oauthid", "oauthsecret");
			var response = host.GetToDynamic(2, "cfs/{fileStore}/{filepath}/{filename}", false, new RestGetOptions
			{
				PathParameters = new System.Collections.Specialized.NameValueCollection {
	  { "fileStore", "communityserver.wikis.components.files" },
	  { "filepath", "00-00-00-00-04" },
	  { "filename", "google.png" }
				}
			});

This is going to return the file, so dynamic won't work, you need to GetToStream

Thank you for your support. It Worked like a charm!

 We had downloaded Telligent.Rest.SDK.dll from github inorder to perform the job as specified in the documentation.

Now our Requirement is to deploy it on Production.

Now we are on 10.1.7 .  we had tested it on our dev environment. It works fine .

If the same deployed on Prod. does we face any issues ? 

I am not sure why anything would be different
