OAuth (v4.0)
pac4j allows you to login with identity providers using the OAuth v1.0 and v2.0 protocol.
1) Dependency
You need to use the following module: pac4j-oauth.
Example (Maven dependency):
<dependency>
<groupId>org.pac4j</groupId>
<artifactId>pac4j-oauth</artifactId>
<version>${pac4j.version}</version>
</dependency>
2) Available clients
a) Generic clients
You can use the OAuth10Client or the OAuth20Client clients to login with an OAuth 1.0 or 2.0 server.
In the latter case, you may use the GenericApi20.
Example to simulate the BitbucketClient:
OAuth10Configuration config = new OAuth10Configuration();
config.setKey("bjEt8BMpLwFDqZUvp6");
config.setSecret("NN6fVXRTcV2qYVejVLZqxBRqHgn3ygD4");
config.setApi(new BitBucketApi());
config.setProfileDefinition(new BitbucketProfileDefinition());
OAuth10Client client = new OAuth10Client();
client.setCallbackUrl(PAC4J_BASE_URL);
client.setConfiguration(config);
Example to simulate the GithubClient:
OAuth20Configuration config = new OAuth20Configuration();
config.setApi(GitHubApi.instance());
config.setProfileDefinition(new GitHubProfileDefinition());
config.setScope("user");
config.setKey("62374f5573a89a8f9900");
config.setSecret("01dd26d60447677ceb7399fb4c744f545bb86359");
OAuth20Client client = new OAuth20Client();
client.setConfiguration(config);
client.setCallbackUrl(PAC4J_BASE_URL);
Example to simulate the GenericOAuth20Client:
We can set the appropriate converter per profile attribute.
For example, the type specified by the following expression:
String|name
Do not specify the type with the following expression:
name
Currently supported types are:Integer,Boolean,Color,Gender,Locale,Long,URI,String(Not specified by default)
Note: If the profile contains non-character type fields, and you have not specified the type, it will be lost, so you must specify a type for any non-character profile field.
GenericOAuth20Client client = new GenericOAuth20Client();
Map map = new HashMap();
map.put(AGE, "Integer|age");
map.put(IS_ADMIN, "Boolean|is_admin");
map.put(BG_COLOR, "Color|bg_color");
map.put(GENDER, "Gender|gender");
map.put(BIRTHDAY, "Locale|birthday");
map.put(ID, "Long|id");
map.put(BLOG, "URI|blog");
map.put("name", "name"); //default String
client.setProfileAttrs(map);
b) Specific clients
By default, many clients are available to login with many identity providers:
Example:
FacebookClient facebookClient = new FacebookClient("145278422258960", "be21409ba8f39b5dae2a7de525484da8");
TwitterClient twitterClient = new TwitterClient("CoxUiYwQOSFDReZYdjigBA", "2kAzunH5Btc4gRSaMr7D7MkyoJ5u1VzbOOzE8rBofs");
