15 The Google API Ruby Client makes it trivial to discover and access supported
20 Be sure `http://rubygems.org/` is in your gem sources.
22 For normal client usage, this is sufficient:
24 $ sudo gem install google-api-client
26 The command line interface, the example applications, and the test suite
27 require additional dependencies. These may be obtained with:
29 $ sudo gem install google-api-client --development --force --no-rdoc --no-ri
33 # Initialize the client & Google+ API
34 require 'google/api_client'
35 client = Google::APIClient.new
36 plus = client.discovered_api('plus')
38 # Initialize OAuth 2.0 client
39 client.authorization.client_id = '<CLIENT_ID_FROM_API_CONSOLE>'
40 client.authorization.client_secret = '<CLIENT_SECRET>'
41 client.authorization.redirect_uri = '<YOUR_REDIRECT_URI>'
43 client.authorization.scope = 'https://www.googleapis.com/auth/plus.me'
45 # Request authorization
46 redirect_uri = client.authorization.authorization_uri
48 # Wait for authorization code then exchange for token
49 client.authorization.code = '....'
50 client.authorization.fetch_access_token!
53 result = client.execute(
54 :api_method => plus.activities.list,
55 :parameters => {'collection' => 'public', 'userId' => 'me'}
64 To take full advantage of the client, load API definitions prior to use. To load an API:
66 urlshortener = client.discovered_api('urlshortener')
68 Specific versions of the API can be loaded as well:
70 drive = client.discovered_api('drive', 'v2')
72 Locally cached discovery documents may be used as well. To load an API from a local file:
74 doc = File.read('my-api.json')
75 my_api = client.register_discovery_document('myapi', 'v1', doc)
79 Most interactions with Google APIs require users to authorize applications via OAuth 2.0. The client library uses [Signet](https://github.com/google/signet) to handle most aspects of authorization. For additional details about Google's OAuth support, see [Google Developers](https://developers.google.com/accounts/docs/OAuth2).
81 Credentials can be managed at the connection level, as shown, or supplied on a per-request basis when calling `execute`.
83 For server-to-server interactions, like those between a web application and Google Cloud Storage, Prediction, or BigQuery APIs, use service accounts. Assertions for service accounts are made with `Google::APIClient::JWTAsserter`.
85 client = Google::APIClient.new
86 key = Google::APIClient::PKCS12.load_key('client.p12', 'notasecret')
87 service_account = Google::APIClient::JWTAsserter.new(
88 '123456-abcdef@developer.gserviceaccount.com',
89 'https://www.googleapis.com/auth/prediction',
91 client.authorization = service_account.authorize
95 Some Google APIs support batching requests into a single HTTP request. Use `Google::APIClient::BatchRequest`
96 to bundle multiple requests together.
100 client = Google::APIClient.new
101 urlshortener = client.discovered_api('urlshortner')
103 batch = Google::APIClient::BatchRequest.new do |result|
107 batch.add(:api_method => urlshortener.url.insert,
108 :body_object => { 'longUrl' => 'http://example.com/foo' })
109 batch.add(:api_method => urlshortener.url.insert,
110 :body_object => { 'longUrl' => 'http://example.com/bar' })
111 client.execute(batch)
113 Blocks for handling responses can be specified either at the batch level or when adding an individual API call. For example:
115 batch.add(:api_method=>urlshortener.url.insert, :body_object => { 'longUrl' => 'http://example.com/bar' }) do |result|
121 For APIs that support file uploads, use `Google::APIClient::UploadIO` to load the stream. Both multipart and resumable
122 uploads can be used. For example, to upload a file to Google Drive using multipart
124 drive = client.discovered_api('drive', 'v2')
126 media = Google::APIClient::UploadIO.new('mymovie.m4v', 'video/mp4')
128 'title' => 'My movie',
129 'description' => 'The best home movie ever made'
131 client.execute(:api_method => drive.files.insert,
132 :parameters => { 'uploadType' => 'multipart' },
133 :body_object => metadata,
136 To use resumable uploads, change the `uploadType` parameter to `resumable`. To check the status of the upload
137 and continue if necessary, check `result.resumable_upload`.
139 client.execute(:api_method => drive.files.insert,
140 :parameters => { 'uploadType' => 'resumable' },
141 :body_object => metadata,
143 upload = result.resumable_upload
147 client.execute(upload)
152 Included with the gem is a command line interface for working with Google APIs.
155 google-api oauth-2-login --client-id='...' --client-secret='...' --scope="https://www.googleapis.com/auth/plus.me"
157 # List the signed-in user's activities
158 google-api execute plus.activities.list --api=plus -- userId="me" collection="public"
160 # Start an interactive API session
162 >> plus = $client.discovered_api('plus')
163 >> $client.execute(plus.activities.list, {'userId' => 'me', 'collection' => 'public'})
164 => # returns a response from the API
