1.利用后台将用户名和密码进行base64加密,浏览器输入登录地址url进行登录
var Base64={_keyStr:"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=",encode:function(e){var t="";var n,r,i,s,o,u,a;var f=0;e=Base64._utf8_encode(e);while(f<e.length){n=e.charCodeAt(f++);r=e.charCodeAt(f++);i=e.charCodeAt(f++);s=n>>2;o=(n&3)<<4|r>>4;u=(r&15)<<2|i>>6;a=i&63;if(isNaN(r)){u=a=64}else if(isNaN(i)){a=64}t=t+this._keyStr.charAt(s)+this._keyStr.charAt(o)+this._keyStr.charAt(u)+this._keyStr.charAt(a)}return t},decode:function(e){var t="";var n,r,i;var s,o,u,a;var f=0;e=e.replace(/[^A-Za-z0-9+/=]/g,"");while(f<e.length){s=this._keyStr.indexOf(e.charAt(f++));o=this._keyStr.indexOf(e.charAt(f++));u=this._keyStr.indexOf(e.charAt(f++));a=this._keyStr.indexOf(e.charAt(f++));n=s<<2|o>>4;r=(o&15)<<4|u>>2;i=(u&3)<<6|a;t=t+String.fromCharCode(n);if(u!=64){t=t+String.fromCharCode(r)}if(a!=64){t=t+String.fromCharCode(i)}}t=Base64._utf8_decode(t);return t},_utf8_encode:function(e){e=e.replace(/rn/g,"n");var t="";for(var n=0;n<e.length;n++){var r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r)}else if(r>127&&r<2048){t+=String.fromCharCode(r>>6|192);t+=String.fromCharCode(r&63|128)}else{t+=String.fromCharCode(r>>12|224);t+=String.fromCharCode(r>>6&63|128);t+=String.fromCharCode(r&63|128)}}return t},_utf8_decode:function(e){var t="";var n=0;var r=c1=c2=0;while(n<e.length){r=e.charCodeAt(n);if(r<128){t+=String.fromCharCode(r);n++}else if(r>191&&r<224){c2=e.charCodeAt(n+1);t+=String.fromCharCode((r&31)<<6|c2&63);n+=2}else{c2=e.charCodeAt(n+1);c3=e.charCodeAt(n+2);t+=String.fromCharCode((r&15)<<12|(c2&63)<<6|c3&63);n+=3}}return t}}
//抓取浏览器访问路径
var request = {
QueryString: function (val) {
var uri = window.location.search;
var re = new RegExp("" + val + "\=([^\&\?]*)", "ig");
return ((uri.match(re)) ? (uri.match(re)[0].substr(val.length + 1)) : null);
}
}
var userNameBase64 = request.QueryString("userName"); //用户名
var userPasswordBase64 = request.QueryString("userPassword"); //密码
//base64解密
var userName = Base64.decode(userNameBase64);
var userPassword = Base64.decode(userPasswordBase64);
console.log("userName="+userName+" userPassword="+userPassword);
if(userName!=null && userPassword!=null){
var oBtn = document.getElementById('btnUsrLogin');
oBtn.onclick = function(){
$("#txtUsrAccount").val(userName);
$("#txtUsrPwd").val(userPassword);
var name = $("#txtUsrAccount").val();
var pwd = $("#txtUsrPwd").val();
// alert("用户名="+name+" and 密码="+pwd);
};
setTimeout("oBtn.click()",1000);
//模拟点击事件,页面刷新,出发点击事件
}
java实现base64加密和解密方法
//加密
public static String getBase64(String str){
byte[] b=null;
String s=null;
try {
b = str.getBytes("utf-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
if(b!=null){
s=new BASE64Encoder().encode(b);
}
return s;
}
// 解密
public static String getFromBase64(String s) {
byte[] b = null;
String result = null;
if (s != null) {
BASE64Decoder decoder = new BASE64Decoder();
try {
b = decoder.decodeBuffer(s);
result = new String(b, "utf-8");
} catch (Exception e) {
e.printStackTrace();
}
}
return result;
}
