HTTP URL - 参数名称中允许的字符 [英] HTTP URL - allowed characters in parameter names

问题描述

对于 URL 参数名称中允许使用哪些字符，是否有任何正式限制?

Is there any formal restriction as to which characters are allowed in URL parameter names?

我一直在阅读 RFC3986(统一资源标识符 (URI): 通用语法")，但没有得出明确的结论.

I've been reading RFC3986 ("Uniform Resource Identifier (URI): Generic Syntax") but came to no definitive conclusion.

我知道有实际限制，但实际上是否会禁止执行以下操作:

I know there are practical limitations, but would it actually be forbidden to do something like:

param withfunny<chars>=some_value

只要我正确转义:

param%20with%1cfunny%3cchars%3e=some_value

推荐答案

URI 规范中对转义参数名称没有限制.但是，您使用的服务器端软件可能存在限制.如果您使用自制"脚本来解释 URI，则尤其如此.

There are no restrictions on escaped parameter names in the URI specs. There might be restrictions in the server-side software that you use, though. This is especially true if you use "homemade" scripts to interpret URIs.
