Getting started

API for testing OAuth2 with Dropbox

How to Build

You must have Python 2 >=2.7.9 or Python 3 >=3.4 installed on your system to install and run this SDK. This SDK package depends on other Python packages like nose, jsonpickle etc. These dependencies are defined in the requirements.txt file that comes with the SDK. To resolve these dependencies, you can use the PIP Dependency manager. Install it by following steps at https://pip.pypa.io/en/stable/installing/.

Python and PIP executables should be defined in your PATH. Open command prompt and type pip --version. This should display the version of the PIP Dependency Manager installed if your installation was successful and the paths are properly defined.

• Using command line, navigate to the directory containing the generated files (including requirements.txt) for the SDK.
• Run the command pip install -r requirements.txt. This should install all the required dependencies.

How to Use

The following section explains how to use the DropboxTestApi SDK package in a new project.

1. Open Project in an IDE

Open up a Python IDE like PyCharm. The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

Click on Open in PyCharm to browse to your generated SDK directory and then click OK.

The project files will be displayed in the side bar as follows:

2. Add a new Test Project

Create a new directory by right clicking on the solution name as shown below:

Name the directory as "test"

Add a python file to this project with the name "testsdk"

Name it "testsdk"

In your python file you will be required to import the generated python library using the following code lines

from dropbox_test_api.dropbox_test_api_client import DropboxTestApiClient

After this you can write code to instantiate an API client object, get a controller object and make API calls. Sample code is given in the subsequent sections.

3. Run the Test Project

To run the file within your test project, right click on your Python file inside your Test project and click on Run

How to Test

You can test the generated SDK and the server with automatically generated test cases. unittest is used as the testing framework and nose is used as the test runner. You can run the tests as follows:

1. From terminal/cmd navigate to the root directory of the SDK.
2. Invoke pip install -r test-requirements.txt
3. Invoke nosetests

Initialization

Authentication

In order to setup authentication and initialization of the API client, you need the following information.

Parameter	Description
o_auth_client_id	OAuth 2 Client ID
o_auth_client_secret	OAuth 2 Client Secret
o_auth_redirect_uri	OAuth 2 Redirection endpoint or Callback Uri

API client can be initialized as following.

# Configuration parameters and credentials
o_auth_client_id = 'o_auth_client_id' # OAuth 2 Client ID
o_auth_client_secret = 'o_auth_client_secret' # OAuth 2 Client Secret
o_auth_redirect_uri = 'o_auth_redirect_uri' # OAuth 2 Redirection endpoint or Callback Uri

client = DropboxTestApiClient(o_auth_client_id, o_auth_client_secret, o_auth_redirect_uri)

You must now authorize the client.

Authorizing your client

Your application must obtain user authorization before it can execute an endpoint call. The SDK uses OAuth 2.0 authorization to obtain a user's consent to perform an API request on the user's behalf.

1. Obtain user consent

To obtain user's consent, you must redirect the user to the authorization page. The get_authorization_url() method creates the URL to the authorization page.

auth_url = client.auth.get_authorization_url()

2. Handle the OAuth server response

Once the user responds to the consent request, the OAuth 2.0 server responds to your application's access request by redirecting the user to your redirect URI.

If the user approves the request, the authorization code will be sent as the code query string:

https://example.com/oauth/callback?code=XXXXXXXXXXXXXXXXXXXXXXXXX

If the user does not approve the request, the response contains an error query string:

https://example.com/oauth/callback?error=access_denied

3. Authorize the client using the code

After the server receives the code, it can exchange this for an access token. The access token is an object containing information for authorizing client requests and refreshing the token itself.

try:
    client.auth.authorize('code')
except OAuthProviderException as ex:
    # handle exception

Refreshing token

An access token may expire after some time. To extend its lifetime, you must refresh the token.

if client.auth.token_expired():
    try:
        client.auth.refresh_token()
    except OAuthProviderException as ex:
        # handle exception

If a token expires, the SDK will attempt to automatically refresh the token before the next endpoint call requiring authentication.

Storing an access token for reuse

It is recommended that you store the access token for reuse.

You can store the access token in a file or a database.

# store token
save_token_to_database(client.config.o_auth_token)

However, since the the SDK will attempt to automatically refresh the token when it expires, it is recommended that you register a token update callback to detect any change to the access token.

client.config.o_auth_callback = save_token_to_database

The token update callback will be fired upon authorization as well as token refresh.

Creating a client from a stored token

To authorize a client from a stored access token, just set the access token after creating the client:

client = DropboxTestApiClient()
client.config.o_auth_token = load_token_from_database()

Class Reference

List of Controllers

• FilesController

FilesController

Get controller instance

An instance of the FilesController class can be accessed from the API Client.

 files_controller = client.files

get_file_count

TODO: Add a method description

def get_file_count(self)

Example Usage

result = files_controller.get_file_count()
