使用Java HttpUrlConnection发送带有令牌的GET请求

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class HttpUrlConnectionExample {
    public static void main(String[] args) {
        String token = "your_token_here";
        String url = "https://api.example.com/endpoint";

        try {
            URL apiUrl = new URL(url);
            HttpURLConnection connection = (HttpURLConnection) apiUrl.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Authorization", "Bearer " + token);

            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
                String line;
                StringBuilder response = new StringBuilder();

                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();

                System.out.println("Response: " + response.toString());
            } else {
                System.out.println("Request failed with response code: " + responseCode);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
