Capacitor OAuth 2 client plugin

This a generic OAuth 2 client plugin.

It let you configure the oauth parameters yourself instead of using SDKs. Therefore it is usable with various providers. See providers the community has already used this plugin with.

Supported flows

Starting with version 2.0.0 the plugin will no longer restrict the responseType to token or code.

Developers can configure anything. It is their responsibility to use the options the chosen OAuth Provider supports.

See the excellent article about OAuth2 response type combinations.

https://medium.com/@darutk/diagrams-of-all-the-openid-connect-flows-6968e3990660

The plugin on the other will behave differently depending on the existence of certain config parameters:

These parameters are:

accessTokenEndpoint
resourceUrl

e.g.

If responseType=code, pkceDisable=true and accessTokenEndpoint is missing the authorizationCode will be resolve along with the whole authorization response. This only works for the Web and Android. On iOS the used lib does not allows to cancel after the authorization request see #13.

Tested / working flows

These flows are already working and were tested by me.

Implicit flow

responseType: "token"

Code flow + PKCE

...
responseType: "code"
pkceEnable: true
...

Please be aware that some providers (OneDrive, Auth0) allow Code Flow + PKCE only for native apps. Web apps have to use implicit flow.

Important

For security reasons this plugin does/will not support Code Flow without PKCE.

That would include storing your client secret in client code which is highly insecure and not recommended. That flow should only be used on the backend (server).

Installation

npm i -E @byteowls/capacitor-oauth2

Minimum Capacitor version is 2.0.0

Configuration

This example shows the common process of configuring this plugin.

Although it was taken from a Angular application, it should work in other frameworks as well.

Register plugin

Find the init component of your app, which is in Angular app.component.ts and register this plugin by

import {registerWebPlugin} from "@capacitor/core";
import {OAuth2Client} from '@byteowls/capacitor-oauth2';

@Component()
export class AppComponent implements OnInit {

    ngOnInit() {
        console.log("Register custom capacitor plugins");
        registerWebPlugin(OAuth2Client);
        // other stuff
    }
}

Use it

import {
  Plugins
} from '@capacitor/core';

@Component({
  template: '<button (click)="onOAuthBtnClick()">Login with OAuth</button>' +
   '<button (click)="onOAuthRefreshBtnClick()">Refresh token</button>' +
   '<button (click)="onLogoutClick()">Logout OAuth</button>'
})
export class SignupComponent {
    refreshToken: string;

    onOAuthBtnClick() {
        Plugins.OAuth2Client.authenticate(
            oauth2Options
        ).then(response => {
            let accessToken = response["access_token"];
            this.refreshToken = response["refresh_token"];

            // only if you include a resourceUrl protected user values are included in the response!
            let oauthUserId = response["id"];
            let name = response["name"];

            // go to backend
        }).catch(reason => {
            console.error("OAuth rejected", reason);
        });
    }

    // Refreshing tokens only works on iOS/Android for now
    onOAuthRefreshBtnClick() {
      if (!this.refreshToken) {
        console.error("No refresh token found. Log in with OAuth first.");
      }

      Plugins.OAuth2Client.refreshToken(
        oauth2RefreshOptions
      ).then(response => {
        let accessToken = response["access_token"];
        // Don't forget to store the new refresh token as well!
        this.refreshToken = response["refresh_token"];
        // Go to backend
      }).catch(reason => {
          console.error("Refreshing token failed", reason);
      });
    }

    onLogoutClick() {
            Plugins.OAuth2Client.logout(
                oauth2Options
            ).then(() => {
                // do something
            }).catch(reason => {
                console.error("OAuth logout failed", reason);
            });
        }
}

Options

See the oauth2Options and oauth2RefreshOptions interfaces at https://github.com/moberwasserlechner/capacitor-oauth2/blob/master/src/definitions.ts for details.

Example:

{
      authorizationBaseUrl: "https://accounts.google.com/o/oauth2/auth",
      accessTokenEndpoint: "https://www.googleapis.com/oauth2/v4/token",
      scope: "email profile",
      resourceUrl: "https://www.googleapis.com/userinfo/v2/me",
      web: {
        appId: environment.oauthAppId.google.web,
        responseType: "token", // implicit flow
        accessTokenEndpoint: "", // clear the tokenEndpoint as we know that implicit flow gets the accessToken from the authorizationRequest
        redirectUrl: "http://localhost:4200",
        windowOptions: "height=600,left=0,top=0"
      },
      android: {
        appId: environment.oauthAppId.google.android,
        responseType: "code", // if you configured a android app in google dev console the value must be "code"
        redirectUrl: "com.companyname.appname:/" // package name from google dev console
      },
      ios: {
        appId: environment.oauthAppId.google.ios,
        responseType: "code", // if you configured a ios app in google dev console the value must be "code"
        redirectUrl: "com.companyname.appname:/" // Bundle ID from google dev console
      }
    }

Platform: Web/PWA

This implementation just opens a browser window to let users enter their credentials.

As there is no provider SDK used to accomplish OAuth, no additional javascript files must be loaded and so there is no performance impact using this plugin in a web application.

Platform: Android

Prerequisite: Capacitor Android Docs

Register the plugin

The plugin must be manually added to your com.companyname.appname.MainActivity. See the Capacitor Docs or below:

// Other imports...
import com.byteowls.capacitor.oauth2.OAuth2ClientPlugin;

public class MainActivity extends BridgeActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Initializes the Bridge
        this.init(savedInstanceState, new ArrayList<Class<? extends Plugin>>() {{
            // Additional plugins you've installed go here. Use a import or the full qualified class name of the plugin (FQCN).
            add(com.byteowls.capacitor.oauth2.OAuth2ClientPlugin.class);
            // NOTE: The FQCN is redundant but it is clearer especially if someone is not familiar with Android/Java programming.
        }});
    }
}

Android Default Config

Skip this, if you use a OAuth2CustomHandler

android/app/src/main/res/AndroidManifest.xml

The AndroidManifest.xml in your Capacitor Android project already contains

    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="@string/custom_url_scheme" />
    </intent-filter>

Find the following line in your AndroidManifest.xml

<data android:scheme="@string/custom_url_scheme" />

and change it to

<data android:scheme="@string/custom_url_scheme" android:host="oauth" />

Note: Actually any value for android:host will do. It does not has to be oauth.

This will fix an issues within the oauth workflow when the application is shown twice. See Issue #15 for details what happens.

android/app/src/main/res/values/strings.xml

In your strings.xml change the custom_url_scheme string to your actual scheme value. Do NOT include ://oauth/redirect or other endpoint urls here!

<string name="custom_url_scheme">com.example.yourapp</string>

<!-- wrong -->
<!-- <string name="custom_url_scheme">com.example.yourapp://endpoint/path</string> -->

android/app/build.gradle

android.defaultConfig.manifestPlaceholders = [
  // change to the 'custom_url_scheme' value in your strings.xml. They need to be the same. e.g.
  "appAuthRedirectScheme": "com.example.yourapp"
]

Troubleshooting

If your appAuthRedirectScheme does not get recognized because you are using a library that replaces it (e.g.: onesignal-cordova-plugin), you will have to add it to your buildTypes like the following:

android.buildTypes.debug.manifestPlaceholders =  [
  'appAuthRedirectScheme': '<@string/custom_url_scheme from string.xml>' // e.g. com.companyname.appname
]
android.buildTypes.release.manifestPlaceholders = [
  'appAuthRedirectScheme': '<@string/custom_url_scheme from string.xml>' // e.g. com.companyname.appname
]

"ERR_ANDROID_RESULT_NULL": See Issue #52 for details. I cannot reproduce this behaviour. Moreover there might be situation this state is valid. In other cases e.g. in the linked issue a configuration tweak fixed it.

Custom OAuth Handler

Some OAuth provider (Facebook) force developers to use their SDK on Android.

This plugin should be as generic as possible so I don't want to include provider specific dependencies.

Therefore I created a mechanism which let developers integrate custom SDK features in this plugin. Simply configure a full qualified classname in the option property android.customHandlerClass. This class has to implement com.byteowls.capacitor.oauth2.handler.OAuth2CustomHandler.

See a full working example below!

Platform: iOS

Register plugin

On iOS the plugin is registered automatically by Capacitor.

iOS Default Config

Skip this, if you use a OAuth2CustomHandler

Open ios/App/App/Info.plist in XCode and add the value of redirectUrl from your config without :/ like that

	<key>CFBundleURLTypes</key>
	<array>
		<dict>
			<key>CFBundleURLSchemes</key>
			<array>
				<string>com.companyname.appname</string>
			</array>
		</dict>
	</array>

Android and iOS

Since October 2018 Strict Mode for Redirect Urls is always on.

Use Strict Mode for Redirect URIs

Only allow redirects that use the Facebook SDK or that exactly match the Valid OAuth Redirect URIs. Strongly recommended.

Before that it was able to use fb<your_app_id>:/authorize in a Android or iOS app and get the accessToken.

Unfortunately now we have to use the SDK for Facebook Login.

I don't want to have a dependency to facebook for users, who don't need Facebook OAuth.

To address this problem I created a integration with custom code in your app customHandlerClass

Android

See https://developers.facebook.com/docs/facebook-login/android/ for more background on how to configure Facebook in your Android app.

Add implementation 'com.facebook.android:facebook-login:4.36.0' to android/app/build.gradle as dependency.
Add to string.xml

    <string name="facebook_app_id"><YOUR_FACEBOOK_APP_ID></string>
    <string name="fb_login_protocol_scheme">fb<YOUR_FACEBOOK_APP_ID></string>

Add to AndroidManifest.xml

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>

<activity android:name="com.facebook.FacebookActivity"
  android:configChanges=
    "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
  android:label="@string/app_name" />

<activity android:name="com.facebook.CustomTabActivity" android:exported="true">
  <intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="@string/fb_login_protocol_scheme" />

public class YourAndroidFacebookOAuth2Handler implements OAuth2CustomHandler {

  @Override
  public void getAccessToken(Activity activity, PluginCall pluginCall, final AccessTokenCallback callback) {
    AccessToken accessToken = AccessToken.getCurrentAccessToken();
    if (AccessToken.isCurrentAccessTokenActive()) {
      callback.onSuccess(accessToken.getToken());
    } else {
      LoginManager l = LoginManager.getInstance();
      l.logInWithReadPermissions(activity, Collections.singletonList("public_profile"));
      l.setLoginBehavior(LoginBehavior.WEB_ONLY);
      l.setDefaultAudience(DefaultAudience.NONE);
      LoginManager.getInstance().registerCallback(((MainActivity) activity).getCallbackManager(), new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
          callback.onSuccess(loginResult.getAccessToken().getToken());
        }

        @Override
        public void onCancel() {
          callback.onCancel();
        }

        @Override
        public void onError(FacebookException error) {
          callback.onCancel();
        }
      });
    }

  }

  @Override
  public boolean logout(Activity activity, PluginCall pluginCall) {
    LoginManager.getInstance().logOut();
    return true;
  }
}

Change your MainActivity like

public class MainActivity extends BridgeActivity {

  private CallbackManager callbackManager;

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    FacebookSdk.sdkInitialize(this.getApplicationContext());

    callbackManager = CallbackManager.Factory.create();

    // add my plugins here
    List<Class<? extends Plugin>> additionalPlugins = new ArrayList<>();
    // Additional plugins you've installed go here
    additionalPlugins.add(OAuth2ClientPlugin.class);
    // Ex: additionalPlugins.add(TotallyAwesomePlugin.class);

    // Initializes the Bridge
    this.init(savedInstanceState, additionalPlugins);
  }

  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (callbackManager.onActivityResult(requestCode, resultCode, data)) {
      return;
    }
  }

  public CallbackManager getCallbackManager() {
    return callbackManager;
  }

}

This handler will be automatically discovered up by the plugin and handles the login using the Facebook SDK. See https://developers.facebook.com/docs/swift/login/#custom-login-button for details.

The users that have redirect problem after success grant add the following code to ios/App/App/AppDelegate.swift. This code correctly delegate the FB redirect url to be managed by Facebook SDK.

import UIKit
import FacebookCore
import FacebookLogin
import Capacitor

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    // other methods

    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
      // Called when the app was launched with a url. Feel free to add additional processing here,
      // but if you want the App API to support tracking app url opens, make sure to keep this call

      if let scheme = url.scheme, let host = url.host {
        let appId: String = Settings.appID!
        if scheme == "fb\(appId)" && host == "authorize" {
          return ApplicationDelegate.shared.application(app, open: url, options: options)
        }
      }

      return CAPBridge.handleOpenUrl(url, options)
    }

    // other methods
}
