[JAVA] J'ai essayé d'automatiser tout, y compris l'authentification en deux étapes de Google OAuth
J'aime personnellement l'implémentation autour de l'authentification, mais je n'ai pas implémenté Google OAuth, j'ai donc profité de l'occasion pour l'implémenter.
La fonction OAuth est fournie par divers fournisseurs tels que FaceBook, Yahoo et Twitter, mais pour Google, les paramètres sont générés dynamiquement par JavaScript à chaque fois, de sorte que la partie authentification utilise chromedriver / Selenium (bibliothèque de scraping) et le navigateur. Nous avons décidé de mettre en œuvre l'authentification automatique de base.
De plus, lorsque la connexion automatique est gênante, Google nécessite une authentification en deux étapes en plus du nom d'utilisateur et du mot de passe, ce qui vaut donc la peine d'être automatisé. .. Lorsque vous essayez de vous connecter automatiquement, Google enverra un code d'authentification pour l'authentification en deux étapes à l'adresse e-mail de réinitialisation, mais cette fois, j'ai ignoré cet e-mail à un serveur de messagerie de réception uniquement utilisant AWS SES et que Après avoir stocké le courrier dans S3, le code de vérification écrit dans le corps du courrier est automatiquement lu et la valeur est automatiquement saisie.
Les paramètres SES sont maintenant renouvelés, mais juste au cas où, l'URL de référence est répertoriée ci-dessous. https://docs.aws.amazon.com/ja_jp/ses/latest/DeveloperGuide/receiving-email-setting-up.html
La séquence est la suivante, mais j'ai essayé d'automatiser tout le flux suivant (démarrage du navigateur> demande d'authentification> authentification> émission de jetons d'accès).
environnement: Java: 1.8 Selenium: 3.12.0 ChromeDriver: 77.0.3865.40 Chrome: 77.0.3865.90
Puisque Maven a été utilisé comme outil de construction cette fois, le contenu de pom.xml est le suivant.

Après avoir exécuté le code ci-dessus et terminé l'authentification / l'autorisation, vous pouvez enfin obtenir le jeton d'accès comme suit.
