13. Integrating with Google Drive
Getting Started

14. Steps for integrating your app w/ Drive
Prerequisites:
• Create a project in the Google APIs Console
• Enable the Drive API
• Create OAuth 2.0 credentials
Integration steps:
• Auth with OAuth 2.0 [& OpenID Connect]
• Write code for opening / saving / managing files

15. OAuth 2.0
Introduction

16. A cool tool...
OAuth 2.0 Playground

17. Integrating with Google Drive
Handling Authorization for Web apps

18. Authorization
Using OAuth 2.0 - Redirecting users to the Grant screen
Python
decorator = OAuth2Decorator(client_id=settings.CLIENT_ID,
client_secret=settings.CLIENT_SECRET,
scope=settings.SCOPE,
user_agent='we-cloud')
class Documents(webapp.RequestHandler):
@decorator.oauth_required
def get(self):
user = users.get_current_user()
if user:
service = build('drive', 'v2', http=decorator.http())

19. Integrating with Google Drive
Interacting with Drive files

20. Instantiating the Drive service Object
Python
# Here is the Drive service
service = build('drive', 'v2', http=decorator.http())

21. Creating Folders
Python
folder = {
'title': self.request.get('project[name]'),
'mimeType': 'application/vnd.google-apps.folder'
}
created_folder = service.files().insert(body=folder).execute()
projectcollectionid = created_folder['id']

22. Creating Files
Python
mimetype = 'application/vnd.google-apps.' + self.request.get('doc[type]')
document = {
'title': self.request.get('doc[name]'),
'mimeType': mimetype
}
if projectcollectionid:
document['parents'] = [{'id': projectcollectionid}]
created_document = service.files().insert(body=document).execute()
resourceid = created_document['id']

23. Sharing Files
Python
#Share the file with other members
new_permission = {
'value': email,
'type': 'user',
'role': 'writer'
}
service.permissions().insert(fileId=fileid, body=new_permission).execute()

24. Searching for files
def retrieve_all_files(service,query):
result = []
page_token = None
param = {}
param['q'] = "fullText contains '"+ query + "'"
param['fields'] = "items(id,parents/id)"
while True:
try:
if page_token:
param['pageToken'] = page_token
files = service.files().list(**param).execute()
result.extend(files['items'])
page_token = files.get('nextPageToken')
if not page_token:
break
except errors.HttpError, error:
Python

25. Integrating with Google Drive
Adding the Drive Web-UI Integration

26. UI Integration - "Create"

27. UI Integration - "Open with"

28. Distribution - Chrome Web Store

29. Steps for adding Drive UI integration
Prerequisites:
• Create a Chrome Web Store listing
(Painful !)
• Install the application from the CWS
• Enable and configure the Drive SDK in the Google APIs Console
Integration steps:
• Support OAuth 2.0 server-side flow
• Read action and file ID from URL parameter

30. Passing context on open & create
What happens when somebody launches your app from Drive?
URL
https://www.yourapp.com/drive?code=<authorization code>&state=<JSON>
JSON
{
"action" : "create",
"parentId" : "0ADK06pfg"
Create actions
"action" : "open",
"ids" : ["0Bz0bd"]
Open actions
}
{
}

31. Integrating with Google Drive
The Google Picker

32. UI Integration - Embedded file picker

33. Embedding the picker
JS
google.setOnLoadCallback(createPicker);
google.load('picker', '1');
var view = new google.picker.View(google.picker.ViewId.DOCS);
view.setMimeTypes("image/png,image/jpeg,image/jpg");
function createPicker() {
picker = new google.picker.PickerBuilder()
.enableFeature(google.picker.Feature.MULTISELECT_ENABLED)
.setAppId(YOUR_APP_ID)
.addView(view)
.setCallback(pickerCallback)
.build();
picker.setVisible(true);

34. Handling picker selections
JS
// A simple callback implementation.
function pickerCallback(data) {
if (data.action == google.picker.Action.PICKED) {
var fileId = data.docs[0].id;
alert('The user selected: ' + fileId);
}
}
