URL url = new URL("your_url");HttpURLConnection connection = (HttpURLConnection) url.openConnection();// 设置请求方式connection.setRequestMethod("GET");// 设置请求头参数connection.setRequestProperty("header1", "value1");connection.setRequestProperty("header2", "value2");

CloseableHttpClient httpClient = HttpClients.createDefault();HttpGet httpGet = new HttpGet("your_url");// 设置请求头参数httpGet.setHeader("header1", "value1");httpGet.setHeader("header2", "value2");CloseableHttpResponse response = httpClient.execute(httpGet);
