但是当我将第一个传递给 URI.encode 时，它不会转义方括号.我也试过 CGI.escape，但这也转义了所有的/".

But when I pass the first one into URI.encode, it doesn't escape the square brackets. I also tried CGI.escape, but that escapes all the '/' as well.

我应该使用什么来正确转义 URL?为什么 URI.encode 不转义方括号?

What should I use to escape URLS properly? Why doesn't URI.encode escape square brackets?

推荐答案

encode 不转义括号，因为它们并不特殊——它们在 URI 的路径部分没有特殊含义，所以他们实际上并不需要转义.

encode doesn't escape brackets because they aren't special -- they have no special meaning in the path part of a URI, so they don't actually need escaping.

如果您想转义除不安全"字符以外的字符，请将第二个参数传递给 encode 方法.该 arg 应该是一个正则表达式匹配，或者一个包含您想要编码的每个字符的字符串(包括 字符，否则函数将已经匹配！).

If you want to escape chars other than just the "unsafe" ones, pass a second arg to the encode method. That arg should be a regex matching, or a string containing, every char you want encoded (including chars the function would otherwise already match!).
