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();
                        }
