Java HTTP 请求读取响应正文

Question

如何读取 HTTP 请求的正文？。我正在寻找一种简单的方法，我认为这是最简单的。

URL url = new URL("http://www.y.com/url");
InputStream is = url.openStream();
try {
  /* Now read the retrieved document from the stream. */
  ...
} finally {
  is.close();
}

但是我如何在控制台中读取或打印错误？有没有更简单的方法来发出请求和读取响应正文？

Answer 1

how can i read this or print in the console please

使用 BufferedReader 并尝试使用资源：

URL url = new URL("http://www.y.com/url");
try(BufferedReader br = new BufferedReader(new InputStreamReader(url.openStream()))) {
    br.lines().forEach(System.out::println);
}

Answer 2

如果你使用Java 9+,你可以使用HttpClient,HttpRequest和HttpResponse.

HttpClient client=HttpClient.newHttpClient();
HttpRequest request=HttpRequest.newBuilder().uri(new URI(your url)).GET().build();
HttpResponse<String> response=client.send(request,BodyHandlers.ofString());
System.out.println(response.body());
