2013.07.22（2）——— android 验证码与cookie

验证码图片与cookie对应，注册时需要把验证码以及cookie传回服务器，这里就需要在获取验证码图片时得到cookie，并且注册时传回cookie

1、得到cookie

//加载验证码private class LoadVcodeThread implements Runnable{private Handler handler;public LoadVcodeThread(Handler handler){this.handler = handler;}@Overridepublic void run() {if(Constant.isNetConnect){int count = 0;while(isRunningVcode){String url = Constant.vcode_url;HttpClient client = new DefaultHttpClient();HttpGet get = new HttpGet(url);HttpResponse response;final String fileName = "vcode.png";String cookies = "";FileOutputStream fileOutputStream = null;try {response = client.execute(get);Header bean = response.getLastHeader("Set-Cookie");cookies = bean.getValue();HttpEntity entity = response.getEntity();InputStream is = entity.getContent();File file = null;String root = null;if (is != null) {root = UtilFile.getFolderPath(UtilFile.DIR_VERIFY);            file = new File(root+"/"+fileName);            if(file.exists()){            file.delete();            }fileOutputStream = new FileOutputStream(file);byte[] buf = new byte[1024];int ch = -1;while ((ch = is.read(buf)) != -1) {fileOutputStream.write(buf, 0, ch);}}fileOutputStream.flush();final String filePath = file.getAbsolutePath();BitmapFactory.Options options=new BitmapFactory.Options();options.inJustDecodeBounds=true;//只得到图片大小信息 不分配内存options.inPreferredConfig = Bitmap.Config.RGB_565;Bitmap tempBitmap=BitmapFactory.decodeFile(filePath, options);int scale=(int)(options.outWidth/UtilManager.getInstance()._utilPhone.getPxFromDip(80));options.inJustDecodeBounds=false;if(scale > 1){options.inSampleSize=scale;//设置缩放级别}tempBitmap = BitmapFactory.decodeFile(filePath, options);if(tempBitmap==null){file.deleteOnExit();if(count==3){isRunningVcode = false;handler.sendEmptyMessage(MSG_REGIST_VCODE_FAIL);}else{count++;}}else{isRunningVcode = false;Message msg = new Message();msg.what = MSG_REGIST_VCODE_SUC;Object [] tArr = {tempBitmap, cookies};msg.obj = tArr;handler.sendMessage(msg);}} catch (Exception e) {e.printStackTrace();}}}else{}}}

2、传回cookie

public static String queryStringForGet(String url, String cookies){HttpGet request = UtilHttp.getHttpGet(url);//BasicHeader tHeader =  new BasicHeader("Set-Cookie", cookies);//request.setHeader(tHeader);request.setHeader("Cookie", cookies);UtilLog.log(TAG, "url: "+url + ", cookies: " + cookies);try {return getResult(request);}catch(ConnectTimeoutException e){e.printStackTrace();//queryStringForGet(url);}catch(SocketTimeoutException e){e.printStackTrace();//queryStringForGet(url);}catch (Exception e) {e.printStackTrace();}return null;}
