从何处获取新Firebase云消息API的java范围依赖项？

FCMAPI被更新为v1，现在你不能传递很多关于它的例子，没有关于作用域的信息。但这是什么？在哪里可以买到？我找不到关于它的任何信息。请帮助我

我尝试过的这种获取访问令牌的方法不起作用。但是你可以尝试直接http请求

public static void main(String args[]) throws IOException {
       public final static String   AUTH_KEY_FCM    = "server key";
       public final static String   API_URL_FCM     = 
                                      "https://fcm.googleapis.com/fcm/send";

    // Method to send Notifications from server to client end.

    // userDeviceIdKey is the device id you will query from your database

    String authKey = AUTH_KEY_FCM; // You FCM AUTH key
    String FMCurl = API_URL_FCM;

    URL url = new URL(FMCurl);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();

    conn.setUseCaches(false);
    conn.setDoInput(true);
    conn.setDoOutput(true);

    conn.setRequestMethod("POST");
    conn.setRequestProperty("Authorization", "key=" + authKey);
    conn.setRequestProperty("Content-Type", "application/json");

    JSONObject json = new JSONObject();
    json.put("to",
            "Device key");
    JSONObject info = new JSONObject();
    info.put("title", "Demo"); // Notification title
    info.put("body", "Hello Test notification"); // Notification body
    json.put("notification", info);

    OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
    wr.write(json.toString());
    wr.flush();
    conn.getInputStream();

    BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream())));

    String output;
    System.out.println("Output from Server .... \n");
    while ((output = br.readLine()) != null) {
        System.out.println(output);
    }
}

}授权范围是我在页面上找到的列表。起初我不明白它们是干什么用的，但后来我猜到了

范围是字符串列表。我已经尝试了来自的多个端点，并且成功了

作用域自：为了授权访问FCM，请求作用域无效这是一个旧API（将很快遗留下来），我尝试使用v1 API。请包括链接中的相关部分。作用域是字符串列表。[ "", "", "" ]

val googleCredential = GoogleCredential.fromStream("yourjson.json")            
.createScoped(Arrays.asList("https://www.googleapis.com/auth/firebase", 
"https://www.googleapis.com/auth/cloud-platform", 
"https://www.googleapis.com/auth/firebase.readonly"))
googleCredential.refreshToken()
return googleCredential.accessToken
