url decode problem 解决方法 |
本文标签:url,decode 试验了一下python的urllib库以及js 的 encodeURIComponent 均不会替换 。空格encode也是替换成了 %20 。python提供了urllib.quote_plus, urlib.unquote_plus来处理空格->加号,看起来还是比较合理的 。 查了一下 RFC 3986: 有下面一段 Scheme names consist of a sequence of characters beginning with a letter and followed by any combination of letters, digits, plus ("+"), period ("."), or hyphen ("-"). RFC 2396 有下面的一段 The plus "+", dollar "$", and comma "," characters have been added to those in the "reserved" set, since they are treated as reserved within the query component. 表示加号已经是url的保留字了,不需要转义 。 然后html4文档里才有关于加号的转义: application/x-www-form-urlencoded Forms submitted with this content type must be encoded as follows: Control names and values are escaped. Space characters are replaced by`+, and then reserved characters..... 声明只有content-type为application/x-www-form-urlencoded时才会对+做转义 。 又翻了下php的文档,发现有一个 rawurlencode() - URL-encode according to RFC 3986 也就是php又搞了rawurlencode和rawurldecode把标准实现了 。 。 。 。 不能反一下么,毕竟大部分人应该都会用urlencode 。php真是蛋疼啊 。 。 。 。 |
