我有一个包含转义网址的字符串:
http%3A%2F%2Fexample.com%3Ffoo%3Dbar+baz
我正在尝试将其解码为以下内容:
http://example.com?foo=bar+baz
但是,我找不到Drakma导出的任何合适的功能。我可以像这样 en 代码:
* url-string
"http://example.com?foo=bar+baz"
* (drakma:url-encode url-string :utf-8)
"http%3A%2F%2Fexample.com%3Ffoo%3Dbar%2Bbaz"
...所以我认为我走在正确的轨道上。如果有人能提供正确方向的推动我会很感激:-)我正在使用SBCL 1.0.54,它是在64位Linux Mint 13上从源代码构建的。
如果它有助于澄清我正在尝试做什么,在Ruby中,我会做以下事情:
> uri_string = "http%3A%2F%2Fexample.com%3Ffoo%3Dbar+baz"
=> "http%3A%2F%2Fexample.com%3Ffoo%3Dbar+baz"
> URI.decode uri_string
=> "http://example.com?foo=bar+baz"

找到另一个解决方案,Quri,一个带有编码和解码实用程序的uri处理库(用于uri和参数):
(url-decode "http%3A%2F%2Fexample.com%3Ffoo%3Dbar%2Bbaz")
;; "http://example.com?foo=bar+baz"
使用(ql:quickload :quri)
安装,然后选择(use-package :quri)
。
