400 Invalid_request 您无法登录此应用，因为它不符合 Google 保护应用安全的 OAuth 2.0 政策

Question

当我尝试在我的 IOS 应用程序中注册 Google 时出现此错误。我有 REVERSED-CLIEND_ID 看起来像这样： com.googleusercontent.apps..... 到目前为止我可以打开 google window 然后我收到 400 错误。

AppDelegate:

class AppDelegate: UIResponder, UIApplicationDelegate {
    
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        ApplicationDelegate.shared.application(application,didFinishLaunchingWithOptions: launchOptions)
        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
    }
    
    func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        ApplicationDelegate.shared.application(
            app,
            open: url,
            sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String,
            annotation: options[UIApplication.OpenURLOptionsKey.annotation]
        )
        var handled: Bool
        
        handled = GIDSignIn.sharedInstance.handle(url)
        if handled {
            return true
        }
        
        // Handle other custom URL types.
        
        // If not handled by this app, return false.
        return false
    }
}

ViewController:

    let signInConfig = GIDConfiguration.init(clientID: "REVERSED_URL_THING")

  @IBAction func googleRegister(_ sender: UIButton) {
        GIDSignIn.sharedInstance.signIn(
            with: signInConfig,
            presenting: self
        ) { user, error in
            guard error == nil else { return }
            guard let user = user else { return }

            // Your user is signed in!
        }
    }

如果有人遇到同样的问题，请在 Xcode 的 URL 类型中添加 iOS URL 方案 和不要像许多教程中所说的那样使用相反的url。使用 Google 提供的 CLIEND ID：

let signInConfig = GIDConfiguration.init(clientID: "CLIENT ID ")
