Problems with uploading files using REST API.

[gıyaseddin tanrıkulu]

Hi there,

I am trying to upload files using REST API but for some reason, when I download these files, I see

a content-disposition header along with a number that is on top and bottom. Here's an example:

--3920b9ce37f4e3292af6d8081aa02501                                                                 
1 Content-Disposition: form-data; name="file"; filename="TODO"

...file content...

--3920b9ce37f4e3292af6d8081aa02501--

I tried to send this with and without header, but regardless the outcome is same. I suspect that upon saving

these files, DSpace mistakenly adds this header to file content.

I tried to upload using python and bash, I'm adding the code snippets in case if they provide any useful information.

Python:

PARAMS = {'Accept': "application/json",
          'Content-Type': "application/json"}

def upload_file(file_path, item_uuid, cookie):
    """ Upload file to a DSpace item.

    Arguments:
    file      -- The path of file to upload.
    item_uuid -- The item UUID in the rest api.
    cookie    -- JSESSIONID for authentication.
    """

    # Add JSESSIONID to request header
    parameters = PARAMS
    parameters["Cookie"] = "JSESSIONID=" + cookie
    parameters["Content-Type"] = "multipart/form-data"

    # Prepare files dict for request
    file = open(file_path, 'rb')
    files = {'file': file}

    response = requests.post(url=URL + "/rest/items/" + item_uuid +"/bitstreams?name=" + os.path.basename(file.name),
                             files=files, headers=parameters)
    pdb.set_trace()

    file.close()

Bash:

curl -k -v -4 --trace dspace.log --cookie "JSESSIONID=2C20ADE1EEC3EA7E225C32884A31EC59" -H "Accept: application/json" -X POST "http://localhost:8080/rest/items/46309f1d-c5fd-4142-80d7-3c850b5f955b/bitstreams?name=test.sh" -T test.sh

This is what i use:

And is working fine.

with open(directory, 'rb') as f:
    file_response = requests.post(rest_items_api_link + item_uuid + "/bitstreams",
                                  files={file_name: f},
                                  params={'name': file_name},
                                  headers={'Content-Type': 'multipart/form-data'},
                                  cookies={"JSESSIONID": "xxxxx"})
    print(file_response.text)
