Question

我的http回复

HttpResponse response = httpClient.execute(request);
                // Read response using StringBuilder
                StringBuilder sb = new StringBuilder();
                BufferedReader reader = new BufferedReader(new InputStreamReader(
                  response.getEntity().getContent()), 65728);
                String line = null;
                while ((line = reader.readLine()) != null) {
                sb.append(line);
                }
                // Print response
                System.out.println(sb.toString());

服务器的响应如下所示

我需要读取PaRes的值，所以我需要xyz值。我尝试使用Enumeration和getParam，但是我总是以null结尾。请告知出路。谢谢。

Answer 1

Document doc = Jsoup.parse(sb.toString());
                Element element = doc.select("input[name=PaRes]").first();
                String inputValue = element.attr("value");
                System.out.println("PaRes    "+inputValue);

从Java中的HTML http响应中读取参数值
