最近几天遇到一些URL参数明文显示的问题,因为是明文显示,容易让人通过改变参数查看到他没有权限看到内容。

一开始我的做法是自定义了规则,然后原始的那种URL编码。可是URL编译后效果不理想,他无法编译数字,而且编码后的字符串太长。

最后我在网上用了BASE64这种。感觉还可以。摘录下来,做一下备忘,以后还会用到

C# BASE64 解码和编码

       string a = "【OK,Let's GO】";
       byte[] b = System.Text.Encoding.Default.GetBytes(a);
       //转成 Base64 形式的 System.String
       a = Convert.ToBase64String(b);
       Console.WriteLine(a);
     //转回到原来的 System.String。
      byte[] c = Convert.FromBase64String(a);
      a = System.Text.Encoding.Default.GetString(c);
      Console.WriteLine(a);
