### 数据加密传输与解密部分代码 ###

1 网页js加密算法

2 模板代码

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>NewsList</title>
        <script type="text/javascript"> document.write('<script type="text/javascript" src="getshow/?t='+Date.parse(new_Date())+'"><\/script>'); </script>
    </head>
    </html>
