java访问第三方接口需要请求头携带token代码

以下是一个使用Java访问第三方接口并携带token的示例代码：

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

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

        try {
            URL url = new URL(apiUrl);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");
            
            // 设置请求头
            conn.setRequestProperty("Authorization", "Bearer " + token);

            int responseCode = conn.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                String inputLine;
                StringBuilder response = new StringBuilder();
                while ((inputLine = in.readLine()) != null) {
                    response.append(inputLine);
                }
                in.close();

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

请将apiUrl替换为您要访问的第三方接口的URL，并将token替换为您的实际访问令牌。这个示例使用HttpURLConnection类进行HTTP请求，并设置了Authorization请求头来携带token。如果请求成功，将打印出响应内容；否则，将打印出响应状态码
