Create PortalItem with zip file

We are trying to upload zip files to AGOL. If I was doing in AGOL I would create the item, define it as a Code Sample (which will allow a generic zip file).

Hoped we could do this in Runtime (100.15). I see this old thread How to create a new FeatureService PortalItem which seems to indicate only saving Maps is supported, but it is 3 years old so would hope that is no longer the case.

Seems pretty simple:

ZipFile.CreateFromDirectory(projectItem.MapPackagePath, outputfile); var portalItem = new PortalItem(portal, PortalItemType.CodeSample, projectItem.Title); using ( var fileStream = File.OpenRead(outputfile) ) { await portalItem.UpdateDataAsync(fileStream); } await portal.User.AddPortalItemAsync(portalItem); await portalItem.ShareWithGroupsAsync(new[] { group });

Couple problems occur.

It requires that the user re-enter credentials on the call to new PortalItem even though authenticated
The primary issue: it never returns from the await portalItem.UpdateDataAsync. It just hangs and so cannot ever put the item in AGOL

Is what I need to do supported? If so what would be a correct way to do this

Thanks - Joe

I believe you can call update only on an existing portal item so I suggest :

- Add PortalItem first then call update

- Enclose UpdateItemAsync() in try catch block to catch any errors.

No exceptions are being thrown, it just does not return from the method call

Never found a way to get anything to work with the Runtime API, but was able to do using the rest endpoint directly.

string zipfileName = CreateProjectZipfile(projectItem); /* Does not seem that Runtime API handles creating a zip file item, so using rest API directly /* https://developers.arcgis.com/rest/users-groups-and-items/add-item.htm */ string url = $"https://www.arcgis.com/sharing/rest/content/users/{portal.User?.UserName}/additem"; using ( var formContent = new MultipartFormDataContent() ) { AddStringContent(formContent, projectItem); AddFileContent(formContent, zipfileName, projectItem); using ( HttpClient client = new HttpClient(new ArcGISHttpClientHandler()) ) { var response = await client.PostAsync(url, formContent); var json = await response.Content.ReadAsStringAsync(); await ShareItemWithGroupAsync(json); } } private void AddStringContent(MultipartFormDataContent formContent, ProjectItem projectItem) { Dictionary<string, string> parameters = new Dictionary<string, string>() { { "multipart", "false" }, { "title", projectItem.Title }, { "type", "Code Sample" }, { "async", "false" }, { "f", "json" } }; // For MultipartFormDataContent paramaters needs to be added as individual StringContent objects. FormUrlEncodedContent does not work. foreach (var keyValuePair in parameters) { formContent.Add(new StringContent(keyValuePair.Value), keyValuePair.Key); } } private void AddFileContent(MultipartFormDataContent formContent, string outputfile, ProjectItem projectItem) { var byteArrayContent = new ByteArrayContent(File.ReadAllBytes(outputfile)); byteArrayContent.Headers.ContentType = new MediaTypeHeaderValue("application/x-zip-compressed"); byteArrayContent.Headers.ContentDisposition = ContentDispositionHeaderValue.Parse("form-data"); byteArrayContent.Headers.ContentDisposition.FileName = $"{projectItem.Title}.zip"; // ContentDisposition.Name needs to match the parameter name byteArrayContent.Headers.ContentDisposition.Name = "file"; formContent.Add(byteArrayContent); }
