Hi! I am adding multiple images (jpg format) to ArcGIS Portal using Python REST API.

So far the part of the code that works (except 'overwrite' parameter) looks like that:

addItem_files = {'file':open(addItem_file_path, 'rb')}
response = requests.post(refererUrl+'/rest/content/users/'
  +username+'/'+addItem_portal_folder+'/addItem?'
  +'token='+portalToken
  +'&overwrite=True'
  +'&type='+addItem_type
  +'&title='+addItem_filename
  +'&tags='+addItem_tags
  +'&culture=pl'
  + '&f=json',
  files=addItem_files)‍‍‍‍‍‍‍‍‍‍‍‍

I have hit a wall when trying to add thumbnails in the process.

Thumbnails are stored in the subfolder and their names correspond to the  original file name ('thumb_*' prefix).

The code with thumbnails implemented look like that:

addItem_files = {'file':open(addItem_file_path, 'rb'),
  'thumbnail':open(addItem_thumbnail_path, 'rb')}
response = requests.post(refererUrl+'/rest/content/users/'
  +username+'/'+addItem_portal_folder+'/addItem?'
  +'token='+portalToken
  +'&overwrite=True'
  +'&thumbnail='+thumbnail_name
  +'&type='+addItem_type
  +'&title='+addItem_filename
  +'&tags='+addItem_tags
  +'&culture=pl'
  + '&f=json',
  files=addItem_files)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Unfortunately there's no result, no thumbnail or even original image.

I would appreciate any suggestions how to properly upload file with thumbnails as well with the overwrite parameter.

Both the thumbnail and overwrite parameters work when using ArcGIS Portal Directory:

/sharing/content/users/user/addItem

Also, I am working with both ArcGIS Portal and ArcGIS Server Linux versions 10.4.1.

Any help on this is highly appreciated.

Thanks!

Are you mimicking the parameters used when going through the workflow in the browser with the dev tools or Fiddler running?

I am trying to use the Portal REST API and the POST method to add item to the Portal following the API reference I have:

REST API reference

Same thing can be achieved for one file trough the rest directory, but only for one file at the time:
REST_AddItem

I have found module from ESRI on GitHub that have "AddItem" function which is basically what I am trying to write myself. But I need to dig into that..
