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。
