+## Description
The Google API Ruby Client makes it trivial to discover and access supported
APIs.
-== Example Usage
-
- # Initialize the client
- require 'google/api_client'
- require 'signet/oauth_1/client'
- client = Google::APIClient.new(
- :service => 'buzz',
- # Buzz has API-specific endpoints
- :authorization => Signet::OAuth1::Client.new(
- :temporary_credential_uri =>
- 'https://www.google.com/accounts/OAuthGetRequestToken',
- :authorization_uri =>
- 'https://www.google.com/buzz/api/auth/OAuthAuthorizeToken',
- :token_credential_uri =>
- 'https://www.google.com/accounts/OAuthGetAccessToken',
- :client_credential_key => 'anonymous',
- :client_credential_secret => 'anonymous'
- )
- )
- client.authorization.fetch_temporary_credential!(
- :additional_parameters => {
- 'scope' => 'https://www.googleapis.com/auth/buzz'
- }
- )
- redirect_uri = client.authorization.authorization_uri(
- :additional_parameters => {
- 'domain' => client.authorization.client_credential_key,
- 'scope' => 'https://www.googleapis.com/auth/buzz'
- }
- )
- # Redirect user here
- client.authorization.fetch_token_credential!(:verifier => '12345')
-
- # Discover available methods
- method_names = client.discovered_api('buzz').to_h.keys
-
- # Make an API call
- response = client.execute(
- 'chili.activities.list',
- {'scope' => '@self', 'userId' => '@me', 'alt' => 'json'}
- )
- status, headers, body = response
-
-== Install
-
-Be sure both http://gems.github.com/ and http://rubygems.org/ are in your gem
-sources.
+## Alpha
+
+This library is in Alpha. We will make an effort to support the library, but we reserve the right to make incompatible changes when necessary.
+
+## Install
+
+Be sure `https://rubygems.org/` is in your gem sources.
For normal client usage, this is sufficient:
-sudo gem install google-api-client
+```bash
+$ gem install google-api-client
+```
+
+## Example Usage
+
+```ruby
+require 'google/api_client'
+require 'google/api_client/client_secrets'
+require 'google/api_client/auth/installed_app'
+
+# Initialize the client.
+client = Google::APIClient.new(
+ :application_name => 'Example Ruby application',
+ :application_version => '1.0.0'
+)
+
+# Initialize Google+ API. Note this will make a request to the
+# discovery service every time, so be sure to use serialization
+# in your production code. Check the samples for more details.
+plus = client.discovered_api('plus')
+
+# Load client secrets from your client_secrets.json.
+client_secrets = Google::APIClient::ClientSecrets.load
+
+# Run installed application flow. Check the samples for a more
+# complete example that saves the credentials between runs.
+flow = Google::APIClient::InstalledAppFlow.new(
+ :client_id => client_secrets.client_id,
+ :client_secret => client_secrets.client_secret,
+ :scope => ['https://www.googleapis.com/auth/plus.me']
+)
+client.authorization = flow.authorize
+
+# Make an API call.
+result = client.execute(
+ :api_method => plus.activities.list,
+ :parameters => {'collection' => 'public', 'userId' => 'me'}
+)
+
+puts result.data
+```
+
+## API Features
+
+### API Discovery
+
+To take full advantage of the client, load API definitions prior to use. To load an API:
+
+```ruby
+urlshortener = client.discovered_api('urlshortener')
+```
+
+Specific versions of the API can be loaded as well:
+
+```ruby
+drive = client.discovered_api('drive', 'v2')
+```
+
+Locally cached discovery documents may be used as well. To load an API from a local file:
+
+```ruby
+# Output discovery document to JSON
+File.open('my-api.json', 'w') do |f| f.puts MultiJson.dump(client.discovery_document('myapi', 'v1')) end
+
+# Read discovery document and load API
+doc = File.read('my-api.json')
+client.register_discovery_document('myapi', 'v1', doc)
+my_api = client.discovered_api('myapi', 'v1')
+```
+
+### Authorization
+
+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).
+
+Credentials can be managed at the connection level, as shown, or supplied on a per-request basis when calling `execute`.
+
+For server-to-server interactions, like those between a web application and Google Cloud Storage, Prediction, or BigQuery APIs, use service accounts.
+
+```ruby
+key = Google::APIClient::KeyUtils.load_from_pkcs12('client.p12', 'notasecret')
+client.authorization = Signet::OAuth2::Client.new(
+ :token_credential_uri => 'https://accounts.google.com/o/oauth2/token',
+ :audience => 'https://accounts.google.com/o/oauth2/token',
+ :scope => 'https://www.googleapis.com/auth/prediction',
+ :issuer => '123456-abcdef@developer.gserviceaccount.com',
+ :signing_key => key)
+client.authorization.fetch_access_token!
+client.execute(...)
+```
+
+Service accounts are also used for delegation in Google Apps domains. The target user for impersonation is specified by setting the `:person` parameter to the user's email address
+in the credentials. Detailed instructions on how to enable delegation for your domain can be found at [developers.google.com](https://developers.google.com/drive/delegation).
+
+### Automatic Retries & Backoff
+
+The API client can automatically retry requests for recoverable errors. To enable retries, set the `client.retries` property to
+the number of additional attempts. To avoid flooding servers, retries invovle a 1 second delay that increases on each subsequent retry.
+In the case of authentication token expiry, the API client will attempt to refresh the token and retry the failed operation - this
+is a specific exception to the retry rules.
+
+The default value for retries is 0, but will be enabled by default in future releases.
+
+### Batching Requests
+
+Some Google APIs support batching requests into a single HTTP request. Use `Google::APIClient::BatchRequest`
+to bundle multiple requests together.
+
+Example:
+
+```ruby
+client = Google::APIClient.new
+urlshortener = client.discovered_api('urlshortner')
+
+batch = Google::APIClient::BatchRequest.new do |result|
+ puts result.data
+end
+
+batch.add(:api_method => urlshortener.url.insert,
+ :body_object => { 'longUrl' => 'http://example.com/foo' })
+batch.add(:api_method => urlshortener.url.insert,
+ :body_object => { 'longUrl' => 'http://example.com/bar' })
+client.execute(batch)
+```
+
+Blocks for handling responses can be specified either at the batch level or when adding an individual API call. For example:
+
+```ruby
+batch.add(:api_method=>urlshortener.url.insert, :body_object => { 'longUrl' => 'http://example.com/bar' }) do |result|
+ puts result.data
+end
+```
+
+### Media Upload
+
+For APIs that support file uploads, use `Google::APIClient::UploadIO` to load the stream. Both multipart and resumable
+uploads can be used. For example, to upload a file to Google Drive using multipart
+
+```ruby
+drive = client.discovered_api('drive', 'v2')
+
+media = Google::APIClient::UploadIO.new('mymovie.m4v', 'video/mp4')
+metadata = {
+ 'title' => 'My movie',
+ 'description' => 'The best home movie ever made'
+}
+client.execute(:api_method => drive.files.insert,
+ :parameters => { 'uploadType' => 'multipart' },
+ :body_object => metadata,
+ :media => media )
+```
+
+To use resumable uploads, change the `uploadType` parameter to `resumable`. To check the status of the upload
+and continue if necessary, check `result.resumable_upload`.
+
+```ruby
+client.execute(:api_method => drive.files.insert,
+ :parameters => { 'uploadType' => 'resumable' },
+ :body_object => metadata,
+ :media => media )
+upload = result.resumable_upload
+
+# Resume if needed
+if upload.resumable?
+ client.execute(upload)
+end
+```
