在ColdFusion中隐藏/加密URL变量

问题描述

如果我有一个网站，且网址为 www.example.com/mainpage.cfm?id=0123&app=2 ，我如何隐藏 id = 0123 和 app = 2 ，因此用户将无法更改这些变量？

我在看一个由我之前的人写的复杂程序，他通过URL将这些变量从一个页面传递到另一个页面。我只是寻找一个快速修复，因为我不想重写整个程序。

解决方案

it：

  #URLEncodedFormat（Encrypt（id，#key＃））＃
  

id是变量，密钥可以是任何（用作证书进行编码和解码）。

要解码：

  cfset url.id = #Decrypt（url.id，#key ＃）＃
  

同样，关键变量也是与要编码的变量相同的变量。 p>

If I have a website and the URL is www.example.com/mainpage.cfm?id=0123&app=2, how can I hide the id=0123 and app=2 so the user won't be able to change these variables?

I am looking at a complex program written by someone before me and he is passing these variables from page to page through the URL. I am just looking for a quick fix because I don't want to rewrite this entire program.

解决方案

Here is how you encode it:

#URLEncodedFormat(Encrypt(id, "#key#"))#

The id is the variable, and the key can be anything (used as a certificate to encode and decode).

To Decode:

cfset url.id = #Decrypt(url.id, "#key#")#

Again the key variable would be the same variable as the one to encode.
