在Java中請(qǐng)求第三方接口可以通過(guò)使用HttpURLConnection或者使用第三方庫(kù)如OkHttp等來(lái)實(shí)現(xiàn)。以下是使用HttpURLConnection請(qǐng)求第三方接口的示例代碼:

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

public class Main {
    public static void main(String[] args) {
        try {
            URL url = new URL("https://api.thirdparty.com/endpoint");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            
            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String inputLine;
            StringBuffer response = new StringBuffer();
            
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();
            
            System.out.println(response.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

上述代碼中通過(guò)創(chuàng)建URL對(duì)象并調(diào)用openConnection方法獲取HttpURLConnection對(duì)象,然后設(shè)置請(qǐng)求方法為GET,最后讀取響應(yīng)內(nèi)容并輸出。請(qǐng)注意,這只是一個(gè)簡(jiǎn)單的示例,實(shí)際中可能需要根據(jù)接口的要求設(shè)置請(qǐng)求頭、請(qǐng)求參數(shù)等。
