在Java中,您可以使用java.net.HttpURLConnection
或者java.net.URL
类来设置HTTP请求的超时。以下是两种方法的示例:
方法1:使用 HttpURLConnection
import java.io.IOException; import java.net.HttpURLConnection; import java.net.URL; public class Main { public static void main(String[] args) { try { URL url = new URL("http://example.com"); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); // 设置连接超时(单位:毫秒) connection.setConnectTimeout(5000); // 设置读取超时(单位:毫秒) connection.setReadTimeout(5000); int responseCode = connection.getResponseCode(); System.out.println("Response Code: " + responseCode); connection.disconnect(); } catch (IOException e) { e.printStackTrace(); } } }
方法2:使用 URL
import java.io.IOException; import java.net.HttpURLConnection; import java.net.URL; public class Main { public static void main(String[] args) { try { URL url = new URL("http://example.com"); HttpURLConnection connection = (HttpURLConnection) url.openConnection(); // 设置连接超时(单位:毫秒) connection.setConnectTimeout(5000); // 设置读取超时(单位:毫秒) connection.setReadTimeout(5000); int responseCode = connection.getResponseCode(); System.out.println("Response Code: " + responseCode); connection.disconnect(); } catch (IOException e) { e.printStackTrace(); } } }
在这两个示例中,我们将连接超时和读取超时都设置为5000毫秒(5秒)。您可以根据需要调整这些值。
