OkHttp OAuth2 client
A modern Android oAuth2 library using OkHttp with resource owner password grant types and easy token refreshing. This library aims to provide a solution for the less commonly used resource owner password grant type as well as providing dynamic parameter support that can be used with frameworks that allow for more flexible and dynamic oAuth2 parameters (such as the Django REST framework social oAuth2 library)
Gradle
The Gradle dependency is available via jCenter. jCenter is the default Maven repository used by Android Studio.
dependencies {
// ... other dependencies here
compile 'ca.mimic:oauth2library:2.3.0'
}
Usage
OAuth2Client client = new OAuth2Client.Builder("username", "password", "client-id", "client-secret", "site").build();
OAuthResponse response = client.requestAccessToken();
if (response.isSuccessful()) {
String accessToken = response.getAccessToken();
String refreshToken = response.getRefreshToken();
}
else {
OAuthError error = response.getOAuthError();
String errorMsg = error.getError();
}
response.getCode();
// HTTP Status codeTo refresh a token (defaults to "refresh_token" grant type)
OAuth2Client client = new OAuth2Client.Builder("client-id", "client-secret", "site").build();
OAuthResponse response = client.refreshAccessToken("refresh-token");
String accessToken = response.getAccessToken();
Callbacks
client.requestAccessToken(new OAuthResponseCallback() {
@Override
public void onResponse(OAuthResponse response) {
if (response.isSuccessful()) {
// response.getAccessToken();
}
else {
// response.getOAuthError();
}
}
}
);
Builder options and parameters
Parameters for the builder
OAuth2Client.Builder builder = new OAuth2Client.Builder("client-id", "client-secret", "site")
.grantType("grant-type")
.scope("scope")
.username("username")
.password("password");
Provide your own OkHttpClient to the builder
OkHttpClient client = new OkHttpClient();
OAuth2Client.Builder builder = new OAuth2Client.Builder("client-id", "client-secret", "site")
.okHttpClient(client);
Provide additional name / value string parameters
Map<String, String> map = new HashMap<>();
map.put("backend", "example-backend");
OAuth2Client.Builder builder = new OAuth2Client.Builder("client-id", "client-secret", "site")
.parameters(map)Wrap with RxJava!
OAuth2Client.Builder builder = new OAuth2Client.Builder("client-id", "client-secret", "http://localhost:8000/auth/token");
final OAuth2Client client = builder.build();
Observable<OAuthResponse> observable = Observable.fromCallable(new Callable<OAuthResponse>() {
@Override
public OAuthResponse call() throws Exception {
return client.refreshAccessToken("refresh-token");
}
}
);
observable.subscribe(new Action1<OAuthResponse>() {
@Override
public void call(OAuthResponse oAuthResponse) {
oAuthResponse.getAccessToken();
}
}
);
Extra response data
OAuthResponse contains other potentially helpful data
OAuthResponse response = client.requestAccessToken();
response.getHttpResponse();
// OkHttp response response.getBody();
// Response body string response.isJsonResponse();
// Was JSON parsed?Acknowledgments
