随笔

其实我也没有想到要写什么要写的，但其实可以写的有很多。

可以写老师，不如

image.png
比如killer，比如严总。
也可以写生活中的 image.png ，比如学校里的事件，如煲鸡汤（聚众讲学 image.png
）。
既然都是笔随心走，那就讲讲我觉得最有意思的事情。
我一个小学同学发来了一个链接，让我帮他搞定这个网站上作品里面的代码。
https://shequ.codemao.cn/work/36685871
于是我动身前往： image.png
毫无悬念，先用开发着工具一探究竟。
image.png
看到下面的那么多<div/>，我开始向上级寻找相关代码。果然不出所料， image.png 。那个作品使用了嵌入式框架，真实的代码在这个网址：https://player.codemao.cn/old/36685871，打开那个网址，看到工具拓展的信息，我惊呆了 image.png 。25个文件，看了一下，这....... image.png
看一下这个网页的源代码： image.png 相当简洁，按照名字排除了2个选项，在浏览这些代码时，我发现了个问题： image.png base64？base64字符的存在说明了后面这一串字符是被用base64加密的。

科普：base64
Base64是网络上最常见的用于传输8Bit字节码的编码方式之一，Base64就是一种基于64个可打印字符来表示二进制数据的方法。可查看RFC2045～RFC2049，上面有MIME的详细规范。
Base64编码是从二进制到字符的过程，可用于在HTTP(一种协议)环境下传递较长的标识信息。采用Base64编码具有不可读性，需要解码后才能阅读。
好处：可以写在代码里，不用上传cdn。
坏处：1.拖慢网页访问速度（特别是base64加密了很的的文件）。2.一个文件经过base64加密后，体积大了差不多1/3。3.加密文件非常吃CPU（中央处理器）。
总结：小文件可以用，大文件算了吧，不如上传IBM CLOUD，反正也不要钱。

解密后成了
