The following is a list of supported OAuth2 flows with a +description of these two steps. + +#### Client-side Web Application + +For client-side only web applications a "Client ID" needs to be created (under +DevConsole -> Project -> APIs & auth -> Credentials). When creating a new client +ID, select the "Web application" type. For client-side only applications, no +`Redirect URIs` are necessary. The `Javascript Origins` setting must be set to +all URLs on which your application will be served (e.g. http://localhost:8080 +for local testing). + +After the Client ID has been created, you can obtain access credentials via + +```dart +import 'package:googleapis_auth/auth_browser.dart'; + +// Initialize the browser oauth2 flow functionality then use it to obtain credentials. +Future obtainCredentials() async { + final flow = await createImplicitBrowserFlow( + ClientId('....apps.googleusercontent.com'), + ['scope1', 'scope2'], + ); + + try { + return await flow.obtainAccessCredentialsViaUserConsent(); + } finally { + flow.close(); + } +} +``` + +or obtain an authenticated HTTP client via + +```dart +import 'package:googleapis_auth/auth_browser.dart'; + +// Initialize the browser oauth2 flow functionality then use it to +// get an authenticated and auto refreshing client. +Future obtainAuthenticatedClient() async { + final flow = await createImplicitBrowserFlow( + ClientId('....apps.googleusercontent.com'), + ['scope1', 'scope2'], + ); + + try { + return await flow.clientViaUserConsent(); + } finally { + flow.close(); + } +} +``` + +To prevent popup blockers from blocking the user authorization dialog, the +methods `obtainAccessCredentialsViaUserConsent` and `clientViaUserConsent` +should preferably only be called inside an event handler, since most browsers do +not block popup windows created in response to a user interaction. + +The authenticated HTTP client can now access data on behalf a user for the +requested oauth2 scopes. + +#### Installed/Console Application + +For installed/console applications a "Client ID" needs to be created (under +DevConsole -> Project -> APIs & auth -> Credentials). When creating a new client +ID, select the "Installed application -> Other" type. + +The redirect URIs for the automatic and manual flow will be configured +automatically. + +After the Client ID has been created, you can obtain access credentials via + +```dart +import 'package:googleapis_auth/auth_io.dart'; +import 'package:http/http.dart' as http; + +// Use the oauth2 authentication code flow functionality to obtain +// credentials. [prompt] is used for directing the user to a URI. +Future obtainCredentials() async { + final client = http.Client(); + + try { + return await obtainAccessCredentialsViaUserConsent( + ClientId('....apps.googleusercontent.com', '...'), + ['scope1', 'scope2'], + client, + _prompt, + ); + } finally { + client.close(); + } +} + +void _prompt(String url) { + print('Please go to the following URL and grant access:'); + print(' => $url'); + print(''); +} +``` + +or obtain an authenticated HTTP client via + +```dart +import 'package:googleapis_auth/auth_io.dart'; + +// Use the oauth2 code grant server flow functionality to +// get an authenticated and auto refreshing client. +Future obtainCredentials() async => await clientViaUserConsent( + ClientId('....apps.googleusercontent.com', '...'), + ['scope1', 'scope2'], + _prompt, +); + +void _prompt(String url) { + print('Please go to the following URL and grant access:'); + print(' => $url'); + print(''); +} +``` + +The Client ID must be created with a `client_secret` here, however there is no +way to properly secure a `client_secret` for installed/console applications. +Fortunately the OAuth2 flow used in this case +[assumes that the app cannot keep secrets](https://developers.google.com/identity/protocols/oauth2/native-app) +so this particular `client_secret` does not need to be kept secret. You should +however make sure not to re-use the same `client_secret` anywhere secrecy is +required. + +In case of misconfigured browsers/proxies or other issues, it is also possible +to use a manual flow via `obtainAccessCredentialsViaUserConsentManual` and +`clientViaUserConsentManual`. But in this case the `prompt` function needs to +complete with a `Future` which contains the "authorization code". The +user obtains the "authorization code" (which is a string of characters) in a +browser and needs to copy & paste it to the application. (The prompt function +should block until it has gotten the "authorization code" from the user.) + +The authenticated HTTP client can now access data on behalf a user for the +requested oauth2 scopes. + +#### Autonomous Application / Service Account + +If an application wants to act autonomously and access e.g. data from a Google +Cloud Project, then a Service Account can be created. In this case no user +authorization is involved. + +A service account can be created via the "Service account" application type when +creating a Client ID (under DevConsole -> Project -> APIs & auth -> +Credentials). It will download a JSON document which contains a private RSA key. +That private key is used for obtaining access credentials. + +After the service account was created, you can obtain access credentials via + +```dart +import "package:googleapis_auth/auth_io.dart"; +import "package:http/http.dart" as http; + +... + +// Use service account credentials to obtain oauth credentials. +Future obtainCredentials() async { + var accountCredentials = ServiceAccountCredentials.fromJson({ + "private_key_id": "", + "private_key": "", + "client_email": "@developer.gserviceaccount.com", + "client_id": ".apps.googleusercontent.com", + "type": "service_account" + }); + var scopes = [...]; + + var client = http.Client(); + AccessCredentials credentials = + await obtainAccessCredentialsViaServiceAccount(accountCredentials, scopes, client); + + client.close(); + return credentials; +} +``` + +or an authenticated HTTP client via + +```dart +import "package:googleapis_auth/auth_io.dart"; + +... + +// Use service account credentials to get an authenticated and auto refreshing client. +Future obtainAuthenticatedClient() async { + final accountCredentials = ServiceAccountCredentials.fromJson({ + "private_key_id": "", + "private_key": "", + "client_email": "@developer.gserviceaccount.com", + "client_id": ".apps.googleusercontent.com", + "type": "service_account" + }); + var scopes = [...]; + + AuthClient client = await clientViaServiceAccount(accountCredentials, scopes); + + return client; // Remember to close the client when you are finished with it. +} +``` + +The authenticated HTTP client can now access APIs. + +##### Impersonation + +For some APIs the use of a service account also requires to impersonate a user. +To support that the `ServiceAccountCredentials` constructors have an optional +argument `impersonatedUser` to specify the user to impersonate. + +One example of this are the Google Apps APIs. See +[Perform Google Apps Domain-Wide Delegation of Authority](https://developers.google.com/admin-sdk/directory/v1/guides/delegation) +for information on the additional security configuration required to enable this +for a service account. + +#### Autonomous Application / Compute Engine using metadata service + +If an application wants to act autonomously and access e.g. data from a Google +Cloud Project, then a Service Account can be used. In case the application is +running on a ComputeEngine VM it is possible to start a VM with a set of scopes +the VM is allowed to use. See the +[documentation](https://cloud.google.com/compute/docs/access/create-enable-service-accounts-for-instances#using) +for further information. + +Here is an example of using the metadata service for obtaining access +credentials on a ComputeEngine VM. + +```dart +import "package:googleapis_auth/auth_io.dart"; +import "package:http/http.dart" as http; + +... + +// Use the metadata service to obtain oauth credentials. +Future obtainCredentials() async { + var client = http.Client(); + + AccessCredentials credentials = + await obtainAccessCredentialsViaMetadataServer(client); + + client.close(); + return credentials; +} +``` + +or an authenticated HTTP client via + +```dart +import "package:googleapis_auth/auth_io.dart"; + +... + +// Use the metadata service to get an authenticated and auto refreshing client. +Future obtainAuthenticatedClient() async { + + AuthClient client = await clientViaMetadataServer(); + + return client; // Remember to close the client when you are finished with it. +} +``` + +The authenticated HTTP client can now access APIs. + +#### Accessing Public Data with API Key + +It is possible to access some APIs by just using an API key without OAuth2. + +An API key can be obtained on the Google Developers Console by creating a Key at +the "Public API access" section (under DevConsole -> Project -> APIs & auth -> +Credentials). + +A key can be created for different application types: For browser applications +it is necessary to specify a set of referer URls from which the application +would like to access APIs. For server applications it is possible to specify a +list of IP ranges from which the client application would like to access APIs. + +Note that the ApiKey is used for quota and billing purposes and should not be +disclosed to third parties. + +Here is an example of getting an HTTP client which uses an API key for making +HTTP requests. + +```dart +import "package:googleapis_auth/auth_io.dart"; + +var client = clientViaApiKey(''); +// [client] can now be used to make REST calls to Google APIs. + +... + +client.close(); +``` + +### More information + +More information can be obtained from official Google Developers documentation: + +- [OAuth2 to Access Google APIs](https://developers.google.com/identity/protocols/oauth2) +- [OAuth2 Playground](https://developers.google.com/oauthplayground/) diff --git a/third_party/googleapis_auth/lib/auth.dart b/third_party/googleapis_auth/lib/auth.dart new file mode 100644 index 00000000..d436be28 --- /dev/null +++ b/third_party/googleapis_auth/lib/auth.dart @@ -0,0 +1,11 @@ +// Copyright (c) 2021, the Dart project authors.
