java中获取response的方法是什么

在Java中，获取response的方法主要是通过使用HttpURLConnection或者HttpClient来发送HTTP请求，然后获取服务器的响应数据。

使用HttpURLConnection获取response的方法如下：

URL url = new URL("http://example.com");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
int responseCode = connection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String line;
StringBuilder response = new StringBuilder();
while ((line = reader.readLine()) != null) {
response.append(line);
}
reader.close();
String responseData = https://www.yisu.com/ask/response.toString();>
使用HttpClient获取response的方法如下：
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpGet httpGet = new HttpGet("http://example.com");
CloseableHttpResponse response = httpClient.execute(httpGet);
int statusCode = response.getStatusLine().getStatusCode();
if (statusCode == HttpStatus.SC_OK) {
HttpEntity entity = response.getEntity();
String responseData = https://www.yisu.com/ask/EntityUtils.toString(entity);>
以上是两种常用的获取response的方法，具体使用哪种方法取决于你的需求和项目环境。
