newlisp标准库没有提供url编码的支持,因此从dragonfly库中找到下面的代码,经过测试可以使用。
;=============================================================================== ; !UTF8 Compatible URL encoding/decoding ;=============================================================================== (constant ‘REGEX_HTTP_SPECIAL_STR (regex-comp {([^.0-9a-z]+)} 1)) (constant ‘REGEX_HEX_ENCODED_CHAR (regex-comp {%([0-9A-F][0-9A-F])} 1)) (define (hex-encode-str str , cnvrt) (setf cnvrt (dup "%%%X" (length str))) (eval (append ‘(format cnvrt) (unpack (dup "b" (length str)) str))) ) ;; @syntax (utf8-urlencode <str> [<bool-everything>]) ;; @param str the string to encode ;; @param bool-everything whether to escape the entire string or just most of the "non-ascii friendly" parts. ;; <p>Use this function to safely encode data that might have foreign characters in it, or simply ;; characters that should be placed into URLs:</p> ;; <b>example:</b> ;; <pre> (utf8-urlencode "What time is it?") => "What%20time%20is%20it%3F"</pre> (define (utf8-urlencode str everything) (if everything (hex-encode-str str) (replace REGEX_HTTP_SPECIAL_STR str (hex-encode-str $1) 0x10000) ) ) ;; @syntax (utf8-urldecode <str>) ;; <p>Decodes a utf8-urlencoded string.
