Firebase REST API Java（不是 Android）。我得到的是 HTML 文本而不是我的数据库值

我正在使用 Firebase 制作新的 REST API Java 项目。我在这里运行了我的代码：

URL url = new URL("https://restapi-example-java-default-rtdb.asia-southeast1.firebasedatabase.app/get");
HttpURLConnection conn = (HttpURLConnection)url.openConnection();

conn.setRequestMethod("GET");
conn.setRequestProperty("Content-Type","application/json");
conn.setRequestProperty("Accept","application/json");
conn.setConnectTimeout(5000);
conn.setDoInput(true);

conn.connect();
System.out.println(conn.getResponseMessage());
int responseCode = conn.getResponseCode();
System.out.println(responseCode);

BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
while ((inputLine = in.readLine()) != null) {
    outResult.append(inputLine);
}

System.out.println(outResult);

但是，我能得到的是某种关于 Google Login 的 html。连接的响应消息和代码 OK 和 200；

我的火力规则：

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

I was making my new REST API Java project with Firebase. I ran my code here:

URL url = new URL("https://restapi-example-java-default-rtdb.asia-southeast1.firebasedatabase.app/get");
HttpURLConnection conn = (HttpURLConnection)url.openConnection();

conn.setRequestMethod("GET");
conn.setRequestProperty("Content-Type","application/json");
conn.setRequestProperty("Accept","application/json");
conn.setConnectTimeout(5000);
conn.setDoInput(true);

conn.connect();
System.out.println(conn.getResponseMessage());
int responseCode = conn.getResponseCode();
System.out.println(responseCode);

BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8"));
while ((inputLine = in.readLine()) != null) {
    outResult.append(inputLine);
}

System.out.println(outResult);

However, what I could get was some kind of html which was about Google Login.
Response Message and Code of the connection was OK and 200;

My firebase rule:

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

要从实时数据库的 REST API 读取，URL 必须以 .json 结尾。因此：

new URL("https://restapi-example-java-default-rtdb.asia-southeast1.firebasedatabase.app/get.json");

                                                                                          //

To read from the REST API of the Realtime Database, the URL must end in .json. So:

new URL("https://restapi-example-java-default-rtdb.asia-southeast1.firebasedatabase.app/get.json");
                                                                                          // ????

Also see the Firebase documentation on getting started with the REST API:

We can use any Firebase Realtime Database URL as a REST endpoint. All we need to do is append .json to the end of the URL and send a request from our favorite HTTPS client.
