Android 获取JSP或ASP的sessionId（Cookie）

如果使用的是httpClient：

                try {

                    HttpResponse response = HttpUtil.httpClient.execute(new HttpGet(url));

                    Header header = response.getFirstHeader("Set-Cookie");

                    if (header != null) {

                        String cookies = header.getValue();

                        String[] strings = cookies.split(";");

                        GlobalData.aspSessionScsbaabr =  strings[0];

                        System.out.println("已经取到session = " + GlobalData.aspSessionScsbaabr);

                    }

                } catch (IOException e) {

                    e.printStackTrace();

                }

如果使用HttpUrlConnection：

try {

                            System.out.println("正在发送");

                            URL url = new URL(doLoginUrl);

                            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

                            urlConnection.setRequestMethod("POST");

                            urlConnection.setDoOutput(true);

                            InputStream inputStream = urlConnection.getInputStream();

                            String session_value = urlConnection.getHeaderField("Set-Cookie");

                            sessionId = session_value.split(";")[0];                             System.out.println("sessionId = " + sessionId);

                            byte[] byte_result = new byte[inputStream.available()];

                            inputStream.read(byte_result);

                            String result = new String(byte_result);



                            System.out.println("返回结果 result = " + result);

                            inputStream.close();

                        } catch (Exception e) {

                            e.printStackTrace();

                        }
