从Android向Localhost发送Api请求

try {

    URL url = new URL("http://localhost/api/endpoint");

    // 打开连接
    HttpURLConnection connection = (HttpURLConnection) url.openConnection();

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

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

    if (responseCode == HttpURLConnection.HTTP_OK) {
        // 读取响应数据
        BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String line;
        StringBuilder response = new StringBuilder();

        while ((line = reader.readLine()) != null) {
            response.append(line);
        }

        reader.close();

        // 处理响应数据
        String responseData = response.toString();
        // TODO: 对响应数据进行处理
    } else {

    // 关闭连接
