项目记录：登陆( 保存用户名密码 kaptcha验证码 shiro权限管理 RSA加密 非明文保存)

1、登陆页代码

1)引入js

<script type="text/javascript" src="${base}/resources/admin/js/jquery.js"></script>
<script type="text/javascript" src="${base}/resources/admin/js/jquery.validate.js"></script>
<script type="text/javascript" src="${base}/resources/admin/js/rsa/jsbn.js"></script>
<script type="text/javascript" src="${base}/resources/admin/js/rsa/prng4.js"></script>
<script type="text/javascript" src="${base}/resources/admin/js/rsa/rng.js"></script>
<script type="text/javascript" src="${base}/resources/admin/js/rsa/rsa.js"></script>
<script type="text/javascript" src="${base}/resources/admin/js/rsa/base64.js"></script>

 

2) 编写js代码

<script type="text/javascript">
$(document).ready(function(){

// RSA加密
$('#myform').submit(function(){
var $password = $('#password');
var $enPassword = $('#enPassword');

var rsaKey = new RSAKey();
rsaKey.setPublic(b64tohex("${modulus}"), b64tohex("${exponent}"));
var enPassword = hex2b64(rsaKey.encrypt($password.val()));
$enPassword.val(enPassword);
});

// 弹出登陆错误信息
if("${failure}"!=""){
alert("${failure}");
}

// JQuery Validate插件登陆表单验证
$('#myform').validate({
rules:{
username:{required:true},
password:{required:true,minlength:5},
kaptcha:{required:true,
remote:{
type:"post",
url:"${base}/kaptchaAjaxCheck",
data:{ kaptcha:function(){ return $('#kaptcha').val();}}
}}
},
messages:{
username:{required:"请输入用户名"},
password:{required:"密码不能为空！",minlength:"密码最小长度为5"},
kaptcha:{required:"验证码不能为空！",remote:jQuery.format("错误的验证码")}}
});

// 验证码
$('#kaptchaImage').click(function () {
$(this).attr('src', '${base}/kaptcha.jpg?' + Math.floor(Math.random()*100) );
});

});
</script>

 

 

3)正文代码

<form action="${base}/admin" method="post" >               // 隐藏域，enPassword，用来设置存放被上面的RSA加密之后的密文代码

username:<input type="text" ><br>

kaptcha:<input type="text" >
</form>
