URL编码—扩音器和问题 [英] URL Encoding—Ampersand Problem

问题描述

我在使用某些字符编码时遇到了一些麻烦，导致我的网站上的搜索表单出现了一些问题.可能的字段值之一在其中有一个&符.选择此项并提交搜索后，&"号编码为:%2526

I'm having some trouble with some character encoding causing some problems with a search form on my website. One of the possible field values has an ampersand in it. When this is selected and a search is submitted the ampersand is encoded to: %2526

使用页面底部的分页链接并导航到结果列表中的第二页，&"号编码为:%26

Upon using the pagination links at the bottom of the page and navigating to the second page in the list of results the ampersand is encoded to: %26

最后...试图导航到列表中的第3页，&"号又改回了:&这打破了形式，因为它假定确实存在一个不存在的变量.

Finally...in an attempt to navigate to the 3rd page in the list the ampersand is changed back to: & This breaks the form as it assumes there's a variable that isn't actually there.

为什么编码会更改?我怎样才能解决这个问题?感谢您的帮助！

Why is the encoding changing? How can I fix this? Thanks for your help!

推荐答案

该字段似乎已被编码两次.首次通过将导致&更改为％26，则urlencoding％26将产生％2526，因为％本身的编码为％25.

It looks like the field is being encoded twice. First pass will result in & changed into %26, then urlencoding %26 will result in %2526, since the encoding for % itself is %25.
