Symfony整合Facebook登入的實作

06 Apr 2021

大致上是都是參考以下教學設定

Easily talk to an OAuth2 server for social functionality in Symfony

https://github.com/knpuniversity/oauth2-client-bundle

Easily implement Facebook login with Symfony 4

https://hugo-soltys.com/blog/easily-implement-facebook-login-with-symfony-4

Facebook 開發者介面

Facebook for Developers
_Code to connect people with Facebook for Developers. Explore AI, business tools, gaming, open source, publishing…_developers.facebook.com

資料表如下，要先增加一個 facebook_id 欄位 ( ORM 屬性是 facebookId )

教學上有提到，認證有 2 種方式

Authenticating with Guard (用的是這個)
Using the new Symfony Authenticator

設定檔 security 設定如下

config/packages/security.yaml

開啟 authenticator

security:  
enable_authenticator_manager: true

設定帳號提供者

providers:    
    app_user_provider:  
    entity:  
        class: App\\Entity\\User  
        property: email  
    oauth:  
        id: knpu.oauth2.user_provider

防火牆設定

firewalls:  
    dev:  
        pattern: ^/(_(profiler|wdt)|css|images|js)/  
        security: false  
    main:        
        entry_point: App\\Security\\LoginFormAuthenticator  
        pattern: ^/  
        user_checker: App\\Security\\UserChecker  
        anonymous: false  
        lazy: true  
        provider: app_user_provider  
        guard:  
        authenticators:  
        - App\\Security\\LoginFormAuthenticator  
        - App\\Security\\MyFacebookAuthenticator
