在URL中有括号可以吗？ [英] Is it ok to have brackets in URL?

问题描述

为我的AdWord广告系列生成网址，并且一些广告系列名称中包含括号（）和 [] 括号。并且一个示例url看起来像这样

  http://www.website.com/?utm_source=google%5BB%2B% 5D& utm_medium = cpc& utm_content = google_ad（B）& utm_campaign =产品
  

这样好吗？

解决方案

圆括号（）可以用于URL的查询部分（即？之后的部分） ）。 ％ - 编码它们是允许的，但不是必需的，因为％28和％29。

括号[]应为％ - 编码，在查询部分显示为％5B和％5D。

示例网址实际上存在于www.website.com请使用www.example.com作为虚拟域名，它保证不存在），因此可以正确形成。

URL语法的一般规则在互联网标准STD 66，目前是 RFC 3986 。其附录A规定了字符规则，列出括号为属于子界限组，在查询部分中不允许使用％-encoding，但括号属于应编码％的gen-delims。

Im generating URLs for my AdWord campaigns and some campangin names have brackets in them ( ) and [ ] brackets. And a sample url looks likes this

http://www.website.com/?utm_source=google%5BB%2B%5D&utm_medium=cpc&utm_content=google_ad(B)&utm_campaign=product

Is this fine?

解决方案

Parentheses "()" may be used as such in the query part of URL (i.e., the part after "?"). It is allowable, but not necessary, to %-encode them, as "%28" and "%29".

Brackets "[]" shall be %-encoded, as "%5B" and "%5D", in the query part.

The sample URL, which is a real URL as www.website.com actually exists (please use www.example.com as a dummy domain name, it is guaranteed to not exist), is thus correctly formed.

The general rules for URL syntax are defined in Internet-standard STD 66, which is currently RFC 3986. Its Appendix A specifies the rules for characters, listing parentheses as belonging to the "sub-delims" group which is allowed without %-encoding in the query part but the brackets as belonging to "gen-delims" which shall be %-encoded.
