¶ Login by Google
¶ Preparatory work
Configure in Google API Console Credentials (opens new window) and Authing Console (opens new window),See Google Mobile。
¶ Integrate steps
¶ Step 1:Add dependency
implementation 'cn.authing:guard:+'
implementation 'com.google.android.gms:play-services-auth:20.2.0'
The Guard compileOnly relies on gms, which allows apps to import on demand, preventing the Guard aar package from getting bigger as more third party logins are supported. Therefore, every time a third-party identity source is added, the App needs to manually add the dependency of the identity source.
Precautions
If you need to obfuscate code, add the following configuration to proguard.cfg to ensure proper use of the sdk:
-keep class com.google.android.gms.** { *; }
¶ Step 2:Initialization
To initialize Guard Android SDK when the application starts:
// context is application or initial activity
// ”AUTHING_APP_ID“ is obtained from the Authing console
Authing.init(context, "AUTHING_APP_ID");
Authing.setAuthProtocol(Authing.AuthProtocol.EOIDC)
¶ Step 3:Use in different scenarios
¶ Use in different scenarios
Start the managed page where login authentication is required:
// this is the activity context
AuthFlow.start(this);
By following the preceding steps, you can quickly and easily configure the Authing management console to automatically have the FaceBook login function. The login entry is displayed in the social login button list on the built-in login interface of the Guard.
¶ Use the Google sign In button
If you use the Google login button we provide.
- Add the following code to the layout file:
<cn.authing.guard.social.view.GoogleLoginButton
android:id="@+id/btn_login"
android:background="@drawable/authing_button_background"
android:textColor="@color/white"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
2. Then handle the event in the code:
GoogleLoginButton button = findViewById(R.id.btn_login);
button.setOnLoginListener(new AuthCallback<UserInfo>() {
@Override
public void call(int code, String message, UserInfo data) {
if (code == 200) {
// login success, data is user info.
} else {
// login fail
}
}
});
¶ Log in to the authorization class using FaceBook
If you don't want to use our built-in buttons and want to implement the UI entirely yourself, you can call the FaceBook class authorization function inside the button click event, which integrates the business logic to pull up the FaceBook authorization login:
Google google = new Google();
google.login(appContext, new AuthCallback<UserInfo>() {
@Override
public void call(int code, String message, UserInfo data) {
if (code == 200) {
// login success, data is user info.
} else {
// login fail
}
}
});
data
contains idToken
and user information (user name
, nickname
, name
, etc.).
Note: When using the Google login button or the FaceBook login authorization class, you need to add the following code to the Activity's onActivityResult function:
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Guard SDK earlier than 1.5.3
if (requestCode == Google.RC_SIGN_IN && data != null) {
data.setAction("cn.authing.guard.broadcast.GOOGLE_LOGIN");
sendBroadcast(data);
}
// Guard SDK 1.5.3 and later
Google.getInstance().onActivityResult(requestCode, resultCode, data);
}
¶ Log into the API using Google
If you want to fully implement the Google login UI and obtain the authorization code logic yourself, after obtaining the authorization code, you can call the following API in exchange for user information:
public static void loginByGoogle(String authCode, @NotNull AuthCallback<UserInfo> callback)
param
authCode
Google authentication code
example
If you only need to get the user information (username
, nickname
, name
, etc.) and idToken
, call:
AuthClient.loginByGoogle(authCode, new AuthCallback<UserInfo>() {
@Override
public void call(int code, String message, UserInfo data) {
if (code == 200) {
// login success, data is user info, contains idToken.
} else {
// login fail
}
}
});
If you only need to get the user information (username
, nickname
, name
, etc.) and idToken
、accessToken
和 refreshToken
,call:
OIDCClient oidcClient = new OIDCClient();
oidcClient.loginByFaceBook(accessToken, new AuthCallback<UserInfo>() {
@Override
public void call(int code, String message, UserInfo data) {
if (code == 200) {
// ogin success, data is user info, contains idToken、accessToken and refreshToken.
} else {
// login fail
}
}
});
