基于JavaSE面向对象实现接收/传输/存储/修改数据等功能
Main:(主方法入口)
只需要编写注册登录的首页,达到预想的方法调用模式,就可以完成.
public class Main { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); while(true) { System.out.println("Ⅰ.注册\nⅡ.登录"); switch (scanner.nextInt()) { case 1: scanner.nextLine(); try { Console.inspect();//1.注册方法的调用 } catch (IOException e) { e.printStackTrace(); } catch (DocumentException e) { e.printStackTrace(); } catch (UserDataException e) { System.out.println(e.getMessage()); } //关联注册操作的自定义异常 break; case 2: scanner.nextLine(); try { Console.logIn();//2.登录方法的调用 } catch (IOException e) { e.printStackTrace(); } catch (DocumentException e) { e.printStackTrace(); } catch (UserDataException e) { System.out.println(e.getMessage()); } //关联登录操作的自定义异常 break; default: System.out.println("选择操作错误!"); break; } } }}Console:(注册&登录方法的集成)
即1.&2.两种方法的实际编写流程以及扩展
public class Console { static SAXReader saxReader = new SAXReader(); static File file = new File(Constant.USERDATA_PATH); // 在main方法中调用的注册方法 public static void signIn() throws DocumentException, IOException, UserDataException { Scanner scanner = new Scanner(System.in); System.out.println("请输入账号:"); String newUserName = scanner.nextLine(); if (isPhone(newUserName)||isEmail(newUserName)){ if (inspect(newUserName)) { System.out.println("请输入密码:"); String newPassWord = scanner.nextLine(); if (isPassword(newPassWord)) { System.out.println("请输入用户昵称:"); String newName = scanner.nextLine(); if (isName(newName)) { System.out.println("用户注册成功!"); // 注册成功以后将用户数据存入数据库XML中,此处调用资源类的注册方法 Source.signIn(newUserName, newPassWord, newName);//1.资源类的注册方法 } else { throw new NameInputErrorException(); } } else { throw new PasswordInputErrorException(); } }else{ throw new UserNameExistException(); } }else { throw new UsernameInputErrorException(); } } // 在main方法中调用的登录方法 public static void logIn() throws DocumentException, UserDataException, IOException { Scanner scanner = new Scanner(System.in); System.out.println("请输入账号:"); // 此处接受控制台输入账号的同时,调用资源类的登录方法判断账号是否存在并接受返回值 UserData userData = Source.logIn(scanner.nextLine());//2.资源类的登录方法 if (userData != null){ System.out.println("请输入密码:"); String passWord = scanner.nextLine(); if (passWord.equals(userData.getPassWord())){ System.out.println("用户"+userData.getName()+"登录成功!"); // 登录成功后可以继续操作的功能 while(true) { System.out.println("请选择需要操作的功能:\nⅠ.查询天气\nⅡ.查询手机号归属地\nⅢ.手速游戏\nⅣ.查询手速游戏全国排行榜"); switch (scanner.nextInt()) { // 此处为工具类的天气查询的方法的调用 case 1: Visit.weatherFuture(); break; // 此处为工具类的号码归属地的方法的调用 case 2: Visit.phoneGet(); break; // 此处为工具类的手速游戏的方法的调用 case 3: Visit.startGame(userData.getName()); break; // 此处为工具类的获取后端数据的方法的调用 case 4: Visit.getTop(); break; default: throw new SelectErrorException(); } } } else{ throw new UserNameMismatchingPassWordException(); } }else{ throw new UsernameInExistenceException(); } } // 以下所有方法为注册登录操作过程中设定的输入条件和判断以完善注册登录过程 // 用来判断注册过程中输入的账号是否已经存在 public static boolean inspect(String userName ) throws DocumentException { Document read = saxReader.read(file); Element rootElement = read.getRootElement(); List<Element> elements = rootElement.elements(); for (Element element : elements) { String text = element.element("userName").getText(); if (text.equals(userName)){ System.out.println("账号已存在!"); return false; } }return true; } // 注册用户的昵称限制 public static boolean isName(String name){ return Pattern.matches(Constant.REGEX_NAME,name); } // 注册用户的账号可为手机号 public static boolean isPhone(String userName){ return Pattern.matches(Constant.REGEX_PHONE, userName); } // 注册用户的账号可为邮箱 public static boolean isEmail(String userName){ return Pattern.matches(Constant.REGEX_EMAIL,userName); } // 注册用户的密码必须含有大小写字母和数字的组合 public static boolean isPassword(String passWord){ return Pattern.matches(Constant.REGEX_PASSWORD,passWord); }}Source:(管控后台资源数据的注入和取出)
即1.&2.两种方法的区分和编写
public class Source { static SAXReader saxReader = new SAXReader(); public static File file = new File(Constant.USERDATA_PATH); // 接受控制台传输过来的数据存储近XML文件中 public static void signIn (String userName,String passWord,String name) throws DocumentException, IOException { Document read = saxReader.read(file); Element rootElement = read.getRootElement(); Element userData = rootElement.addElement(Constant.XML_ELEMENT_BY_ROOT); userData.addAttribute(Constant.XML_ATTRIBUTE_BY_UD,name); Element elementUserName = userData.addElement(Constant.XML_ELEMENT_BY_UD1); Element elementPassWord = userData.addElement(Constant.XML_ELEMENT_BY_UD2); elementUserName.addText(userName); elementPassWord.addText(passWord); OutputFormat outputFormat = OutputFormat.createPrettyPrint(); outputFormat.setEncoding(Constant.ENCODING); XMLWriter xmlWriter = new XMLWriter(new FileWriter(Constant.USERDATA_PATH),outputFormat); xmlWriter.write(read); xmlWriter.close(); } // 接受控制台传输过来的数据经过判断取出对应的数据以用来和接下来的接受做对比 public static UserData logIn (String name) throws DocumentException { Document read = saxReader.read(file); Element rootElement = read.getRootElement(); List <Element> elements = rootElement.elements(); for (Element element : elements) { if (element.element(Constant.XML_ELEMENT_BY_UD1).getText().equals(name)){ Element userName = element.element(Constant.XML_ELEMENT_BY_UD1); Element passWord = element.element(Constant.XML_ELEMENT_BY_UD2); Attribute attribute = element.attribute(Constant.XML_ATTRIBUTE_BY_UD); return new UserData(attribute.getValue(),userName.getText(),passWord.getText()); } }return null;}}Visit:(集成功能工具的方法编写)
重点在于通过URL或者APL地址接口来获取远端数据或者传输数据
public class Visit { public static void weatherFuture() throws IOException { System.out.println("请输入需要查询的城市:"); Scanner scanner = new Scanner(System.in); String city = scanner.nextLine(); URL u = new URL(Constant.API_APP+"weather.future&weaid="+city+Constant.API_APPKEY_SIGN); String result = dataStore(u); Map map = new HashMap(); map.put("result",Weather.ResultBean.class); JSONObject jsonObject = JSONObject.fromObject(result); Weather weather =(Weather) JSONObject.toBean(jsonObject, Weather.class,map); List<Weather.ResultBean> resultBeans = weather.getResult(); for (Weather.ResultBean resultBean : resultBeans) { System.out.println("日期:" + resultBean.getDays() + "\n星期:" + resultBean.getWeek() + "\n温度:"+resultBean.getTemperature()+"\n天气:"+resultBean.getWeather()); } } public static void phoneGet() throws IOException { System.out.println("请输入需要查询的号码:"); Scanner scanner = new Scanner(System.in); String phone = scanner.nextLine(); URL u = new URL(Constant.API_APP+"phone.get&phone="+phone+Constant.API_APPKEY_SIGN); String result = dataStore(u); JSONObject jsonObject = JSONObject.fromObject(result); Telephone telephoneBelong = (Telephone)JSONObject.toBean(jsonObject, Telephone.class); Telephone.ResultBean result1 = telephoneBelong.getResult(); System.out.println("手机号" + result1.getPhone() + "来自" + result1.getAtt() + "\n号码源:" + result1.getOperators()); } private static String dataStore(URL u) throws IOException { InputStream in = u.openStream(); ByteArrayOutputStream out= new ByteArrayOutputStream(); try { byte buf[]= new byte[1024]; int read = 0; while ((read = in.read(buf)) > 0) { out.write(buf, 0, read); } }finally { if (in != null) { in.close(); } } byte b[]=out.toByteArray( ); return new String(b, "utf-8"); } public static void startGame(String username) throws IOException, DocumentException { System.out.println("欢迎来到手速游戏测试平台:" + "\n请选择游戏难度:" + "\nⅠ.简单(10个字符)" + "\nⅡ.一般(20个字符)" + "\nⅢ.困难(30个字符)"); Scanner scanner = new Scanner(System.in); int choice = scanner.nextInt(); for (int i = 3; i > 0; i--) { try { Thread.sleep(1000); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println("游戏"+i+"秒后开始"); }System.out.println("游戏正式开始!"); long timeBegin = new Date().getTime(); String list = duringGame(choice * 10); scanner.nextLine(); if (scanner.nextLine().equals(list)){ long timeEnd = new Date().getTime(); long timeExpend = timeEnd - timeBegin; System.out.println("恭喜你!成绩为:" + timeExpend + "毫秒"); Visit.submitScore(timeExpend,username); }else { System.out.println("游戏失败!"); } } public static String duringGame(int number) throws IOException, DocumentException { String [] gameList = new String[number]; String list = ""; for (int i = 0; i < gameList.length; i++) { int random = 0; if (number == 10){ random = (int)(Math.random()*36);//10+26 }else if (number == 20){ random = (int)(Math.random()*62);//10+26+26 }else if (number == 30){ random = (int)(Math.random()*86);//10+26+26+24 } list = list + Constant.BYTES[random]; } System.out.println(list); return list; } public static void getTop() throws IOException, DocumentException { URL url = new URL(Constant.URL_TOP_TEN); URLConnection urlConnection = url.openConnection(); InputStream inputStream = urlConnection.getInputStream(); byte[] bytes = new byte[1024]; int read = inputStream.read(bytes); String result = new String(bytes,0,read); JSONArray jsonArray = JSONArray.fromObject(result); for (int i = 0; i < jsonArray.size(); i++) { JSONObject jsonObject = jsonArray.getJSONObject(i); Ranking ranking = (Ranking)JSONObject.toBean(jsonObject, Ranking.class); System.out.println("第"+(i+1)+"位用户名:"+ ranking.getNickname() +",分数为"+ ranking.getScore()); } } public static void submitScore(long time, String username) throws IOException, DocumentException { URL url = new URL(Constant.URL_INSERT + "?username="+username+"&score="+time); URLConnection urlConnection = url.openConnection(); InputStream inputStream = urlConnection.getInputStream(); byte[] bytes = new byte[1024]; int read = inputStream.read(bytes); String result = new String(bytes,0,read,Constant.ENCODING); if (result.equals("SUCCESS")){ System.out.println("成绩已提交成功!"); getFirst(); }else{ System.out.println("成绩提交失败!"); } } public static void getFirst() throws IOException, DocumentException { SAXReader saxReader = new SAXReader(); Document document = saxReader.read(new URL(Constant.URL_FIRST)); Element rootElement = document.getRootElement(); String nickname = rootElement.element("nickname").getText(); String score = rootElement.element("score").getText(); System.out.println("目前第一名为:"+nickname+",分数为:"+score); }}Other:(其他工具类)
