java实现http请求

好的，关于java实现http请求，您可以使用Java自带的HttpURLConnection类或者第三方库比如Apache的HttpClient来实现。以下是一个用HttpURLConnection发送GET请求的示例代码：

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

public class HttpUrlConnectionDemo {
    public static void main(String[] args) {
        try {
            URL url = new URL("http://example.com/api"); // 替换成您要请求的url
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");

            BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line = null;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }

            in.close();
            conn.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

希望这个代码示例可以帮到您！
