Firebase Android身份验证失败:expired_token(身份验证令牌已过期)

Question

我遇到Android Firebase Auth使用com.google.gms:google-services:3.0.0和的问题com.google.firebase:firebase-auth:9.0.1.

使用Firebase(Google或Facebook)验证后1小时,我收到以下错误消息:

W/PersistentConnection: pc_0 - Authentication failed: expired_token (Auth token is expired)

为什么Firebase令牌在1小时后过期以及如何延长此有效期？

UPDATE

我仍然遇到此问题,Firebase令牌在1小时后过期.现在我收到以下消息: W/PersistentConnection: pc_0 - Authentication failed: invalid_token (Invalid claim 'kid' in auth header.)

我感谢任何帮助.

尝试实现FirebaseInstanceIdService获取刷新令牌。

访问注册令牌：

您可以通过扩展FirebaseInstanceIdService来访问令牌的值。确保您已将该服务添加到清单中，然后getToken在 的上下文中调用onTokenRefresh，并记录值，如下所示：

    @Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}

每当生成新令牌时都会触发 onTokenRefreshcallback，因此在其上下文中调用可确保getToken您正在访问当前可用的注册令牌。FirebaseInstanceID.getToken() 如果尚未生成令牌，则返回 null。

代码：

import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;


public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {

    private static final String TAG = "MyFirebaseIIDService";

    /**
     * Called if InstanceID token is updated. This may occur if the security of
     * the previous token had been compromised. Note that this is called when the InstanceID token
     * is initially generated so this is where you would retrieve the token.
     */
    // [START refresh_token]
    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);

        // TODO: Implement this method to send any registration to your app's servers.
        sendRegistrationToServer(refreshedToken);
    }
    // [END refresh_token]

    /**
     * Persist token to third-party servers.
     *
     * Modify this method to associate the user's FCM InstanceID token with any server-side account
     * maintained by your application.
     *
     * @param token The new token.
     */
    private void sendRegistrationToServer(String token) {
        // Add custom implementation, as needed.
    }
}

我希望它对你有帮助。
