¶ Login by Huawei

¶ Preparatory work

Configuration work：In Huawei developer platform (opens new window) and Authing Console (opens new window) Configure the application，see Huawei Access Preparations。

Development reference：Please refer to Huawei official documentation (opens new window), Currently, we use the Authorization Code mode of Huawei account services to access Huawei accounts (OAuth 2.0). Please complete Configure AppGallery (opens new window) first The Connect.

¶ Integrate steps

¶ Step 1：Add HMS Core

Please refer to Integrated HMS Core SDK (opens new window) 、Confused configuration script (opens new window) Complete the environment configuration first.

¶ Step 2：Add dependency

dependencies {
    implementation 'cn.authing:guard:+'
    implementation 'com.huawei.hms:hwid:6.9.0.301'
}

¶ Step 3：Initialization

Initialize Guard Android SDK in Application :

// 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 4：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 Huawei login function. The login entry is displayed in the social login button list on the built-in login interface of the Guard.

¶ Use the login button

If you use the HuaWei login button we provide.

1. Add the following code to the layout file:

 <cn.authing.guard.social.view.HuaWeiLoginButton
    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:

HuaWeiLoginButton 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
        }
    }
});

¶ Use the login authorization class

If you don't want to use our built-in buttons and want to implement the UI entirely yourself, you can call the HuaWei class authorization function inside the button click event, which integrates the business logic to pull up the Huawei authorization login:

HuaWei.getInstance().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 login button or the 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);
    HuaWei.getInstance().onActivityResult(requestCode, resultCode, data);
}

¶ Use the login API

If you want to fully implement the Huawei 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 loginByHuaWei(String authCode, @NotNull AuthCallback<UserInfo> callback)

param

authCode Huawei authCode

example

If you only need to get the user information (username, nickname, name, etc.) and idToken, call:

AuthClient.loginByHuaWei(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.loginByHuaWei(authCode, 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
        }
    }
});
