Google

创立 OAuth 客户端 ID

装备 OAuth 同意画面

留意

设置 URL Type

  • 留意设置 URL Schemes 是凭据 iOS 网址通讯协定

设置 OAuth

  • 如果没有设置装备 OAuth 同意画面如下问题

  • 需要对自己站台装备 DNS 设定，传送门

代码

iOS

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    GIDSignIn.sharedInstance.restorePreviousSignIn { user, error in
        if error != nil || user == nil {
          // Show the app's signed-out state.
        } else {
          // Show the app's signed-in state.
        }
    }
    return true
}
/// 登入 google
func googleAction(_ sender: UIButton) {
    // 留意客户端 id 是凭着里的用戶端编号
    let signInConfig = GIDConfiguration(clientID: "xxxxxxx-xxxxxxxxxxxxxx.apps.googleusercontent.com")
    GIDSignIn.sharedInstance.signIn(with: signInConfig, presenting: self) { user, error in
        guard error == nil else { return }
        // If sign in succeeded, display the app's main content View.
    }
}
/// 登出 google
func googleLoginOutAction()  {
    GIDSignIn.sharedInstance.signOut();
}

Flutter

final GoogleSignIn _googleSignIn = GoogleSignIn(
  clientId:
      'xxxxxxx-xxxxxxxxxx.apps.googleusercontent.com',
  scopes: [
    'email',
    'https://www.googleapis.com/auth/contacts.readonly',
  ],

/// google 登录
void googleLoginHandler() async {

Facebook

创立使用，并授权

留意设置 URL Type 等信息

  • 使用编号 (FacebookAppID)
  • 客户端口令 (FacebookClientToken)
  • 显现名称（FacebookDisplayName）

代码

iOS

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

                sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
                annotation: options[UIApplication.OpenURLOptionsKey.annotation]
            )
    return LoginManager.shared.application(app, open: url)
}
/// facebook 登录
@IBAction func facebookAction(_ sender: UIButton) {
    let loginManager = LoginManager()
    loginManager.logIn(permissions: ["public_profile"], from: self) { result, error in

                print("userID: ===> (userID)")
            }
            if let tokenString = result?.token?.tokenString  {
                print("tokenString: ===> (tokenString)")
            }
        }
    }
}
/// 登出 facebook
func facebookLoginOutAction()  {
    let loginManager = LoginManager()
    loginManager.logOut()
}

Flutter

/// facebook 登录
void facebookLoginHandler() async {
  final fb = FacebookLogin();
  final res = await fb.logIn(permissions: [
    FacebookPermission.publicProfile,
    FacebookPermission.email,
  ]);

      // Send access token to server for validation and auth
      final FacebookAccessToken? accessToken = res.accessToken;
      print('Access token: ${accessToken?.token}');
      // Get profile data
      final profile = await fb.getUserProfile();
      print('Hello, ${profile?.name}! You ID: ${profile?.userId}');
      // Get user profile image url
      final imageUrl = await fb.getProfileImageUrl(width: 100);
      print('Your profile image: $imageUrl');
      // Get email (since we request email permission)
      final email = await fb.getUserEmail();
      // But user can decline permission
      if (email != null) print('And your email is $email');
      break;
