Google+ Platform

Quick start for Python

This quick-start app is built in Python and lets you get started with the Google+ platform in a few minutes. The app demonstrates:

  • Using the Google+ Sign-In button to get an OAuth 2.0 refresh token.
  • Exchanging the refresh token for an access token.
  • Making Google+ API requests with the access token, including getting a list of people that the user has circled.
  • Disconnecting the app from the user's Google account and revoking tokens.

System requirements

Requirements that are installed as part of this quick start:

Step 1: Enable the Google+ API

Create a Google APIs Console project, OAuth 2.0 client ID, and register your JavaScript origins:

  1. Go to the Google Developers Console.
  2. Select a project, or create a new one.
  3. In the sidebar on the left, select APIs & auth. APIs is automatically selected.
  4. In the displayed list of APIs, make sure the Google+ API status is set to ON.
  5. In the sidebar on the left, select Credentials.
  6. In the OAuth section of the page, select Create New Client ID.

    In the resulting Create Client ID dialog box, register the origins where your app is allowed to access the Google APIs. The origin is the unique combination of protocol, hostname, and port.

    1. In the Application type section of the dialog, select Web application.
    2. In the Authorized JavaScript origins field, enter the origin for your app. You can enter multiple origins to allow for your app to run on different protocols, domains, or subdomains. Wildcards are not allowed. In the example below, the second URL could be a production URL.
      http://localhost:4567
      http://myproductionurl.example.com
    3. Select Create Client ID.
    4. In the resulting Client ID for web application panel, note or copy the Client ID and Client secret that your app will need to use to access the APIs.

Step 2: Set up the Python quick-start app

  1. Get the latest version of the quick-start. One way is to use git to clone the application repository.

    git clone https://github.com/googleplus/gplus-quickstart-python.git
    

    Or, download the application as a zip file, and extract the library and sample code:

    wget https://github.com/googleplus/gplus-quickstart-python/archive/master.zip
    unzip gplus-quickstart-python-master.zip
    
  2. Change directory into the sample app

    cd gplus-quickstart-python
    
  3. Install the requirements of this quick start

    pip install -r requirements.txt
    
  4. Edit client_secrets.json, and replace YOUR_CLIENT_ID and YOUR_CLIENT_SECRET with the values that you generated in Step 1.

Step 3: Run the application

After you set up your Google API project and configure the sample app, the app is ready to run.

Because you registered http://localhost:4567 as an Authorized JavaScript origin in the Google APIs Console, you will run the sample from that location.

  1. Run the Python quick-start app:

    python signin.py
    
  2. Browse to your quick-start app, which by default is at http://localhost:4567.

After you sign in, the application uses the JavaScript client to retrieve your profile and uses the Python client library to retrieve the people visible to the app.

Clicking Disconnect from Google+ results in the server making a call to Google to revoke the refresh token. The server then removes any data that it acquired from Google about the user to disconnect the app and follow the developer policies.

Next steps

Now that you have learned to create an APIs console project and run a sample app, you can learn more about the Google+ features you can add to your app:

Authentication required

You need to be signed in with Google+ to do that.

Signing you in...

Google Developers needs your permission to do that.
