Looks all right. We have got the access token, and included in the HEADERS. You can print response to see more. Go ahead with OneDrive operations.

Code flow authentication

Code flow returns both access_token and refresh_token which can be used to request new access_token and refresh_token for persistent session. If you are using organization account, you might require consent of organization administrator.

# Get code
URL = 'https://login.microsoftonline.com/common/oauth2/v2.0/authorize'
client_id = "362422eb-d9d6-4245-9eca-2be5cf256450"
permissions = ['offline_access', 'files.readwrite', 'User.Read']
response_type = 'code'
redirect_uri = 'http://localhost:8080/'
scope = ''
for items in range(len(permissions)):
    scope = scope + permissions[items]
    if items < len(permissions)-1:
        scope = scope + '+'

print('Click over this link ' +URL + '?client_id=' + client_id + '&scope=' + scope + '&response_type=' + response_type+\
     '&redirect_uri=' + urllib.parse.quote(redirect_uri))
print('Sign in to your account, copy the whole redirected URL.')
code = getpass("Paste the URL here :")
code = code[(code.find('?code') + len('?code') + 1) :]

URL = 'https://login.microsoftonline.com/common/oauth2/v2.0/token'

response = requests.post(URL + '?client_id=' + client_id + '&scope=' + scope + '&grant_type=authorization_code' +\
     '&redirect_uri=' + urllib.parse.quote(redirect_uri)+ '&code=' + code)

# Get token
data = {
    "client_id": client_id,
    "scope": permissions,
    "code": code,
    "redirect_uri": redirect_uri,
    "grant_type": 'authorization_code',
    "client_secret": client_secret
}

response = requests.post(URL, data=data)

token = json.loads(response.text)["access_token"]
refresh_token = json.loads(response.text)["refresh_token"]

# Refresh token
def get_refresh_token():
    data = {
        "client_id": client_id,
        "scope": permissions,
        "refresh_token": refresh_token,
        "redirect_uri": redirect_uri,
        "grant_type": 'refresh_token',
        "client_secret": 'xxxx-yyyy-zzzz',
    }

    response = requests.post(URL, data=data)

    token = json.loads(response.text)["access_token"]
    refresh_token = json.loads(response.text)["refresh_token"]
    last_updated = time.mktime(datetime.today().timetuple())

    return token, refresh_token, last_updated

token, refresh_token, last_updated = get_refresh_token()

If you have a large data to upload, you may use below mock code inside your upload loop:

elapsed_time = time.mktime(datetime.today().timetuple()) - last_updated

if (elapsed_time < 45*60*60):
    do_something()
else if (elapsed_time < 59*60*60):
    token, refresh_token, last_updated = get_refresh_token()
else:
    go_to_code_flow()

OneDrive operations

URL = 'https://graph.microsoft.com/v1.0/'

HEADERS = {'Authorization': 'Bearer ' + token}

response = requests.get(URL + 'me/drive/', headers = HEADERS)
if (response.status_code == 200):
    response = json.loads(response.text)
    print('Connected to the OneDrive of', response['owner']['user']['displayName']+' (',response['driveType']+' ).', \
         '\nConnection valid for one hour. Refresh token if required.')
elif (response.status_code == 401):
    response = json.loads(response.text)
    print('API Error! : ', response['error']['code'],\
         '\nSee response for more details.')
else:
    response = json.loads(response.text)
    print('Unknown error! See response for more details.')

List folders under root directory

We will print both directory name and item-d

items = json.loads(requests.get(URL + 'me/drive/root/children', headers=HEADERS).text)
items = items['value']
for entries in range(len(items)):
    print(items[entries]['name'], '| item-id >', items[entries]['id'])

Documents | item-id > C1465DBECD7188C9!103
Pictures | item-id > C1465DBECD7188C9!104
Getting started with OneDrive.pdf | item-id > C1465DBECD7188C9!102

Create new folder (in the root directory)

url = URL + 'me/drive/root/children/'
body = {
    "name": "New_Folder",
    "folder": {},
    "@microsoft.graph.conflictBehavior": "rename"
}
response = json.loads(requests.post(url, headers=HEADERS, json=body).text)

Now lets list the directory again:

items = json.loads(requests.get(URL + 'me/drive/root/children', headers=HEADERS).text)
items = items['value']
for entries in range(len(items)):
    print(items[entries]['name'], '| item-id >', items[entries]['id'])

Documents | item-id > C1465DBECD7188C9!103
New_Folder | item-id > C1465DBECD7188C9!106
Pictures | item-id > C1465DBECD7188C9!104
Getting started with OneDrive.pdf | item-id > C1465DBECD7188C9!102

Here we go, we have successfully created the folder New_Folder.

List folders under a sub-folder (need to use item-id)

Note that if you need to create or list sub-folders, you need to use the item-id. The path/folder notation does not work everywhere.

url = URL + 'me/drive/items/C1465DBECD7188C9!106/children'
items = json.loads(requests.get(url, headers=HEADERS).text)
items = items['value']
for entries in range(len(items)):
    print(items[entries]['name'], '| item-id >', items[entries]['id'])

Well there are no files or folders under the New_Folder. Ok let's create one.

url = URL + 'me/drive/items/C1465DBECD7188C9!106/children/'
data = {
    "name": "sub_folder",
    "folder": {},
    "@microsoft.graph.conflictBehavior": "rename"
}

response = json.loads(requests.post(url, headers=HEADERS, json = data).text)

Now let's print the list again.

url = URL + 'me/drive/items/C1465DBECD7188C9!106/children'
items = json.loads(requests.get(url, headers=HEADERS).text)
items = items['value']
for entries in range(len(items)):
    print(items[entries]['name'], '| item-id >', items[entries]['id'])

sub_folder | item-id > C1465DBECD7188C9!107

Rename an item

url = URL + 'me/drive/items/C1465DBECD7188C9!106'
body = {
    "name": "New_folder_2",
}
response = json.loads(requests.patch(url, headers=HEADERS, json = body).text)

url = URL + 'me/drive/items/root/children'
items = json.loads(requests.get(url, headers=HEADERS).text)
items = items['value']
for entries in range(len(items)):
    print(items[entries]['name'], '| item-id >', items[entries]['id'])

Documents | item-id > C1465DBECD7188C9!103
New_folder_2 | item-id > C1465DBECD7188C9!106
Pictures | item-id > C1465DBECD7188C9!104
Getting started with OneDrive.pdf | item-id > C1465DBECD7188C9!102

Move item

# url = URL + 'me/drive/items/{item-id-of-item-to-be-moved}'
# provide item-id-of-destination-directory under parentReference in the body
url = URL + 'me/drive/items/C1465DBECD7188C9!106'
body = {
  "parentReference": {
    "id": "C1465DBECD7188C9!103"
  },
}
response = json.loads(requests.patch(url, headers=HEADERS, json=body).text)

Delete item

url = '/me/drive/items/C1465DBECD7188C9!106'
url = URL + url
confirmation = input('Are you sure to delete the Item? (Y/n):')
if (confirmation.lower()=='y'):
    response = requests.delete(url, headers=HEADERS)
    if (response.status_code == 204):
        print('Item gone! If need to recover, please check OneDrive Recycle Bin.')
else:
    print("Item not deleted.")

Are you sure to delete the Item? (Y/n):y
Item gone! If need to recover, please check OneDrive Recycle Bin.

url = URL + 'me/drive/items/root/children'
items = json.loads(requests.get(url, headers=HEADERS).text)
items = items['value']
for entries in range(len(items)):
    print(items[entries]['name'], '| item-id >', items[entries]['id'])

Documents | item-id > C1465DBECD7188C9!103
Pictures | item-id > C1465DBECD7188C9!104
Getting started with OneDrive.pdf | item-id > C1465DBECD7188C9!102

Find item-id by item name

items = json.loads(requests.get(URL + 'me/drive/items/root/children', headers=HEADERS).text)
look_for_item = 'Documents'
item_id = ''
items = items['value']
for entries in range(len(items)):
    if(items[entries]['name'] == look_for_item):
        item_id = items[entries]['id']
        print('Item-id of', look_for_item, ':', item_id)
        break
if(item_id==''):
            print(look_for_item, 'not found in the directory.')

Item-id of Documents : C1465DBECD7188C9!103

Upload file

url = 'me/drive/root:/example_spectrum.txt:/content'
url = URL + url
content = open('example_spectrum.txt', 'rb')
response = json.loads(requests.put(url, headers=HEADERS, data = content).text)

url = URL + 'me/drive/items/root/children'
items = json.loads(requests.get(url, headers=HEADERS).text)
items = items['value']
for entries in range(len(items)):
    print(items[entries]['name'], '| item-id >', items[entries]['id'])

Documents | item-id > C1465DBECD7188C9!103
Pictures | item-id > C1465DBECD7188C9!104
example_spectrum.txt | item-id > C1465DBECD7188C9!108
Getting started with OneDrive.pdf | item-id > C1465DBECD7188C9!102

Access/Download data

url = 'me/drive/root:/example_spectrum.txt:/content'
url = URL + url
data = requests.get(url, headers=HEADERS).text

You may like to save the data in a file in your local drive.

Upload large files (Can be used to upload small files as well)

If you have files (probably larger than 4 MB), you need to create upload sessions.

url = 'me/drive/items/C1465DBECD7188C9!103:/large_file.dat:/createUploadSession'
url = URL + url
url = json.loads(requests.post(url, headers=HEADERS).text)
url = url['uploadUrl']
file_path = '/local/file/path/large_file.dat'
file_size = os.path.getsize(file_path)
chunk_size = 320*1024*10 # Has to be multiple of 320 kb
no_of_uploads = file_size//chunk_size
content_range_start = 0
if file_size < chunk_size :
    content_range_end = file_size
else :
    content_range_end = chunk_size - 1

data = open(file_path, 'rb')
while data.tell() < file_size:
    if ((file_size - data.tell()) <= chunk_size):
        content_range_end = file_size -1
        headers = {'Content-Range' : 'bytes '+ str(content_range_start)+ '-' +str(content_range_end)+'/'+str(file_size)}
        content = data.read(chunk_size)
        response = json.loads(requests.put(url, headers=headers, data = content).text)
    else:
        headers = {'Content-Range' : 'bytes '+ str(content_range_start)+ '-' +str(content_range_end)+'/'+str(file_size)}
        content = data.read(chunk_size)
        response = json.loads(requests.put(url, headers=headers, data = content).text)
        content_range_start = data.tell()
        content_range_end = data.tell() + chunk_size - 1
data.close()
response2 = requests.delete(url)

OneDrive storage usage

response = json.loads(requests.get(URL + 'me/drive/', headers = HEADERS).text)
used = round(response['quota']['used']/(1024*1024*1024), 2)
total = round(response['quota']['total']/(1024*1024*1024), 2)
print('Using', used, 'GB (', round(used*100/total, 2),'%) of total', total, 'GB.')

Using 0.48 GB ( 9.6 %) of total 5.0 GB.
