在 URL 中可以使用哪些字符? [英] What characters can one use in a URL?

问题描述

我有一个应用程序，它采用 url 中的所有参数，如下所示:/category/subcategory/sub-subcategory.我希望能够在 URL 的末尾给出额外的参数，比如 page-2/order-desc.这将使整个 URL 变成 cat/subcat/sub-subcat{delimiting-character}page-2/order-desc.

I have an application that takes all the parameters in the url like this: /category/subcategory/sub-subcategory. I want to be able to give out extra parameters at the end of the URL, like page-2/order-desc. This would make the whole URL into cat/subcat/sub-subcat{delimiting-character}page-2/order-desc.

我的问题是:我可以使用哪些字符作为 {delimiting-character}.我倾向于更喜欢:"，因为我知道它永远不会出现在其他任何地方，但我不知道它是否符合标准，或者至少将来不会给我带来问题.

My question is: what characters could I use as {delimiting-character}. I tend to prefer ":" as I know for sure it will never appear anyplace else but I don't know if it would be standard compliant or at least if it will not give me problems in the future.

我记得 vimeo 使用过这样的东西:vimeo.com/video:{code} 但他们似乎已经改变了这一点.

As I recall vimeo used something like this: vimeo.com/video:{code} but they seem to have changed this.
