在codeigniter加密时避免使用特定的字符？ [英] Avoid specific characters while encrypting in codeigniter?

问题描述

我需要通过URL传递一些加密的值。有没有办法避免一些字符，如斜线（/）在我们在加密后得到的值？因为在codeigniter中，字符如slash用于分隔URL中的参数。请注意，我不希望任何建议不传递URL中的加密字符串）。

I need to pass some encrypted value through URL. Is there any way to avoid some characters such as slash (/) in the value we are getting after encryption? Because in codeigniter, character such as slash is used for separating parameters in the URL. Please note that i don't want any suggestion to don't pass the encrypted string in URL :)

推荐答案

不是加密（这意味着安全），而是编码。实际上，您的选项基本上是：

What you want is not an encryption (which implies security) but an encoding. In practice, your options are basically:

• urlencode （如果您希望字符串稍微清晰。


• base64 （如果您不想让字符串清晰可见，请使用此字符串）想要节省字符串中的空格）


• 十六进制（如果您不希望字符串清晰易读， ）

• urlencode (Use this if you want the string to be somewhat legible. This also will give you a shorter string than the other two options)
• base64 (use this if you don't want the string to be legible and also want to conserve space in your string)
• hex (use this if you don't want the string to be legible and you don't care about string length)

我不会选择十六进制。决定是否要让字符串清晰易读，并选择其中一个。

I wouldn't choose hex. Decide whether you want the string to be legible and pick one of the two first.
