冒号是否需要在URI查询参数中进行编码？ [英] Do colons require encoding in URI query parameters?

问题描述

我注意到Java的 UriBuilder 不会对我的查询参数值中包含的：字符进行编码（ ISO 8601格式的字符串）。

I've noticed that Java's UriBuilder isn't encoding the : characters included in my query parameter values (ISO 8601-formatted strings).

根据维基百科，似乎冒号应该被编码。

According to Wikipedia, it seems colon should be encoded.

特别是，对查询字符串进行编码时使用以下规则：

In particular, encoding the query string uses the following rules:

• 字母（AZ和az），数字（0- 9）和字符'。'，' - '，'〜'和'_'保持原样


• SPACE被编码为'+'或％20 [需要引证]


• 所有其他字符编码为％FF十六进制表示，其中任何非ASCII字符首先编码为UTF-8（或其他指定的
  编码）

那么，这笔交易是什么？查询参数中的冒号是否应该编码？

So, what's the deal? Should colons in query parameters be encoded or not?

更新：

我查找了URI语法规范（ RFC 3986 ）看起来像查询参数中的冒号实际上并不是必需的。以下是ABNF对URI的摘录：

I looked up the URI Syntax spec (RFC 3986) and it looks like encoding colons in query params really isn't necessary. Here's an excerpt from the ABNF for URI:

URI         = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
query       = *( pchar / "/" / "?" )
pchar         = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved    = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded   = "%" HEXDIG HEXDIG
sub-delims    = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "=

推荐答案

是的，它们应编码为查询字符串。正确的编码是％3A

Yes, they should be encoded in a query string. The correct encoding is %3A

但是，我可以理解为什么UriBuilder没有编码：。您不希望在协议（例如 http：）之后或用户名和密码之间对冒号进行编码（例如 ftp：// username：[e-mail] ）绝对URI。

However, I can understand why UriBuilder isn't encoding :. You don't want to encode the colon after the protocol (eg http:) or between the username and password (eg ftp://username:[e-mail]) in an absolute URI.
