我已经尝试了所有可用的答案,但无济于事.我在这里错过了什么？

private voID sendRegistrationToServer(String token)`{}

解决方法:

正如评论部分所述,问题很模糊,但我有点得到你所要求的.

sendRegistrationToServer()是一个可选方法,可以在Firebase的大多数示例中看到.从GitHub example开始：

package com.@R_301_5561@.firebase.quickstart.fcm;import androID.util.Log;import com.@R_301_5561@.firebase.iID.FirebaseInstanceID;import com.@R_301_5561@.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);        // If you want to send messages to this application instance or        // manage this apps subscriptions on the server sIDe, send the        // Instance ID token to your app server.        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) {        // Todo: Implement this method to send token to your app server.    }}

从这里,您可以看到在onTokenRefresh()内部调用sendRegistrationToServer(),其中生成用于FCM的注册令牌.代码文档已经告诉sendRegistrationToServer()中应该发生什么：

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.

将注册令牌发送到您自己的App Server是可选的,但强烈建议这样做(见FCM docs).这样您就可以拥有令牌供将来使用.
