}2. Write controller
The login method and ulogin method
under the controller package IndexController class
package cn.pangpython.controller;
import com.jfinal.aop.Before;
import com.jfinal.core.Controller;
import com.jfinal.ext.kit.SessionIdKit;
import cn.pangpython.model.User;
import cn.pangpython.utils.DateUtils;
import cn.pangpython.utils.MD5;
import cn.pangpython.validate.RegistValidator;
import cn.pangpython.validate.UserLoginValidator;
/**
* @author pangPython
* 主页控制器
*/
public class IndexController extends Controller {
public void index(){
renderText("index");
}
//渲染注册页面
public void regpage(){
render("regist.html");
}
//处理注册
@Before(RegistValidator.class)
public void regist(){
String pwd = getPara("user.pwd");
String confirm = getPara("reg.confirm");
//验证码验证
boolean result = validateCaptcha("reg.yzm");
if(!result){
setAttr("yzmErrMsg", "验证码错误！");
render("regist.html");
return;
}
//确认密码验证
if(!pwd.equals(confirm)){
setAttr("confirmErrMsg", "请正确填写确认密码！");
render("regist.html");
return;
}
String uname = getPara("user.name");
User user = getModel(User.class);
String reg_time = DateUtils.dateToUnixTimestamp(DateUtils.getNowTime())+"";
//使用用户注册日期作为md5密码加密的盐值,可节省一个salt数据库字段
pwd = MD5.GetMD5Code(pwd+reg_time);
//给user实体类填充数据
user.setName(uname);
user.setPwd(pwd);
user.setRegTime(reg_time);
//使用jfinal的保存操作
user.save();
renderText("注册成功！");
}
public void login(){
render("login.html");
}
@Before(UserLoginValidator.class)
public void ulogin(){
// 验证码结果
boolean result = validateCaptcha("yzm");
if (!result) {
setAttr("yzmErrMsg", "验证码错误！");
render("login.html");
return;
}
String uname = getPara("user.name");
String sql = "select * from user where name = ? limit 1";
User user = User.dao.findFirst(sql, uname);
if (user != null) {
String pwd = MD5.GetMD5Code(getPara("user.pwd") + user.getRegTime());
if (user.getPwd().equals(pwd)) {
// 生成唯一标识
String sessionId = SessionIdKit.me().generate(getRequest());
// 设置服务器端session
setSessionAttr(sessionId, user);
// 设置用户端cookie
setCookie("cuser", sessionId, 60000);
//redirect("/user");
renderText("登录成功！");
} else {
// 密码不正确
setAttr("UnameErrMsg", "用户名或密码不正确！");
render("login.html");
}
} else {
// 用户名不存在
setAttr("UnameErrMsg", "用户名不存在！");
render("login.html");
}
}
}3. Write login validator
UserLoginValidator under the validator package inherits JFinal’s Validator
import com.jfinal.core.Controller;
import com.jfinal.validate.Validator;
public class UserLoginValidator extends Validator {
@Override
protected void handleError(Controller controller) {
controller.keepPara();
}
@Override
protected void validate(Controller arg0) {
validateRequired("user.name", "UnameErrMsg", "请输入用户名！");
validateRequired("user.pwd", "PwdErrMsg", "请输入密码！");
validateRequired("yzm", "yzmErrMsg", "请输入验证码！");
}

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
