Firefox 自动解码 URL？ CodeIgniter允许的字符问题

发布于 2024-10-15 06:29:36 字数 434 浏览 5 评论 0原文

当我在 w3schools 上访问这个地址时，当我按下 Enter 键加载页面时，地址中的 %28 会自动解码为 ( 在 Firefox 地址栏中。

http://www.w3schools.com/TAGS/html_form_submit.asp?text=%28Hello+G

但是，当访问这个地址时（末尾有一个额外的 %），该地址是没有在地址栏中重写。

http://www.w3schools.com/TAGS/html_form_submit.asp?text=%28Hello+G%

任何人都可以解释这种行为吗？它导致我正在处理的 AJAX 调用出现问题（当我发出请求时，来自 document.location.hash 值编码的字符会被自动解码，因为我我使用 CodeIgniter 不允许解码字符。

原文

When visiting this address on w3schools the %28 in the address is automatically decoded to ( in the Firefox address bar as soon as I press enter to load the page.

http://www.w3schools.com/TAGS/html_form_submit.asp?text=%28Hello+G

However, when visiting this address (an extra % at the end) the address is not rewritten in the address bar.

http://www.w3schools.com/TAGS/html_form_submit.asp?text=%28Hello+G%

Can anyone explain this behavior? It is causing problems with an AJAX call I am working on (when I make a request a web page from document.location.hash value encoded characters are being automatically decoded and because I am using CodeIgniter the decoded characters are not allowed.

Firefox 仅解码有效地址，因此“text=%28Hello+G%”将保持不变（正确编码的“%”字符为“%25”）。

%28Hello+G - valid, decoded: (Hello G
%28Hello+G% - invalid: %28Hello+G%
%28Hello+G%25 - valid, decoded: (Hello G%

可能的解决方案：

使用url安全base64（http://www.php.net/manual/en/function.base64-encode.php#103849）而不是urlencode对你的url进行编码
在urlencoding后将“%”字符更改为其他内容

Firefox is decoding only valid addresses, therefore "text=%28Hello+G%" will remain unchanged (properly encoded "%" character is "%25").

%28Hello+G - valid, decoded: (Hello G
%28Hello+G% - invalid: %28Hello+G%
%28Hello+G%25 - valid, decoded: (Hello G%

Possible solutions:

encode your urls with url safe base64 (http://www.php.net/manual/en/function.base64-encode.php#103849) instead of urlencode
change "%" characters into something else after urlencoding
