HttpUtils.sendGet

您可以使用以下代码来发送 GET 请求：

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

public class HttpUtils {
    public static String sendGet(String url) throws Exception {
        // 创建 URL 对象
        URL obj = new URL(url);
        // 创建 HttpURLConnection 对象
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();

        // 设置请求方法为 GET
        con.setRequestMethod("GET");

        // 获取响应码
        int responseCode = con.getResponseCode();

        if (responseCode == HttpURLConnection.HTTP_OK) { // 请求成功
            BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
            String inputLine;
            StringBuilder response = new StringBuilder();

            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();

            return response.toString();
        } else {
            throw new Exception("GET request failed. Response Code: " + responseCode);
        }
    }
}

您可以使用 `HttpUtils.sendGet(url)` 来发送 GET 请求，其中 `url` 是您要请求的 URL。
