5.18~5.21我们的项目实现了登录注册功能

一、注册

邮箱和密码为必填信息，其他信息默认为空

<%String uid=request.getParameter("uid");String password=request.getParameter("password");String confirmPassword=request.getParameter("password");String email=request.getParameter("uid");    int gender=Integer.parseInt(request.getParameter("gender"));String validateCode=request.getParameter("validateCode");String realName=request.getParameter("realName");String tel=request.getParameter("tel");if(uid==null ||uid.trim().equals("") ||  password==null ||password.trim().equals("") || confirmPassword==null ||confirmPassword.trim().equals("") ||  email==null ||email.trim().equals("")){ request.setAttribute("errMsg","请将必填的数据填写完整!");%><jsp:forward page="error.jsp"/>

检验两次密码填写是否一致

<% }else if(!password.equals(confirmPassword)){ request.setAttribute("errMsg","两次密码不匹配!");%><jsp:forward page="error.jsp"/>

检验用户名是否已经存在，存在则报错，不存在则创建新用户成功，将用户信息添加至用户表

<%  }UserService service=new UserService();boolean isExist=service.checkUid(uid);if(isExist){request.setAttribute("errMsg","用户名已经存在！");%><jsp:forward page="error.jsp"/><%}User user=new User();user.setUid(uid);user.setPassword(password);user.setEmail(email);user.setGender(gender);user.setTel(tel);user.setRealName(realName);//String validateCode=Generator.getEmailCode();user.setValidateCode(validateCode);String path = request.getContextPath();String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";//service.addUser(user,basePath);  service.addUser(user);out.println("<script language=\"javascript\">");  out.println("alert(\"注册成功！\")");  out.println("window.location.href=\"preHome.jsp\"");  out.print("</script> ");%>

二、登陆

检验输入用户名是否存在与库表中，并且输入的密码与用户名对应密码是否匹配，匹配则登陆成功

<%  String uid=request.getParameter("uid");  String password=request.getParameter("password");  System.out.println("==="+uid+password);  UserService userService=new UserService();  if(userService.login(uid,password)){       session.setAttribute("uid", uid);   out.println(" <script> window.close();history.go(-2); </script>");     }else{ %>     <font color="red">用户名或密码错误!</font>    <%    }%>
