Special Characters in URL query string
提问by m0g
I have a situation where the user is able to enter any characters they want in a URL query string.
我有一种情况，用户可以在 URL 查询字符串中输入他们想要的任何字符。
Example:
例子：
http://localhost/default.aspx?ID=XXXX
http://localhost/default.aspx?ID=XXXX
http://localhost/default.aspx?ID=&XXXX
http://localhost/default.aspx?ID=&XXXX
http://localhost/default.aspx?ID=#XXXX
http://localhost/default.aspx?ID=#XXXX
The web page must accept the ID parameter as it is no matter what the characters are. However certain special characters such as ampersand(&) and pound(#) creates problems. How can I accept them as is?
网页必须接受 ID 参数，因为无论字符是什么。但是，某些特殊字符，例如与号 (&) 和磅 (#) 会产生问题。我怎样才能按原样接受它们？

If the user is entering the query string, they must properly encode the query string first. If you are creating the query string yourself, such as from a form submission, you will need to use a URL encode method.
如果用户正在输入查询字符串，他们必须首先正确编码查询字符串。如果您自己创建查询字符串，例如从表单提交中创建，您将需要使用 URL 编码方法。
