url如何加密,我做的是静态页面,a页面把视频地址传递给B页面,穿过去的地址如何加密,然后在B页面里解密,播放。谢谢!!!!
如题!
------解决方案--------------------基本上没什么用了
------解决方案--------------------传递
url = "0068007400740070003a002f002f007700770077002e003100360033002e0063006f006d ";
表示http://www.163.com
b页面解码:
function Decode(str)
{
return unescape(str.replace(/[\da-f]{4}/ig, "%u$& "));
}
Decode(url);
a页面的编码函数:
function Encode(str)
{
return str.length ? str.charCodeAt(0).toString(16).replace(/^[\da-f]{2}$/i, "00$& ").concat(arguments.callee(str.slice(1))) : " ";
}
var url = Encode( "http://www.163.com ");
// 0068007400740070003a002f002f007700770077002e003100360033002e0063006f006d
// 因为这些都是在客户端进行的操作,所以基本上是没法做到真正保密的
------解决方案--------------------静态页面加密??? 基本上是没法做到真正保密的哦,给你个base64加密解密的方法
你自己提出来用吧
