在 Rails 3 (Ruby 1.9.2) 中我发送一个请求

 Started GET "/controller/action?path=/41_+"

但是参数列表是这样的:

 {"path"=>"/41_ ",
   "controller"=>"controller",
   "action"=>"action"}

这里出了什么问题？ -、* 或 . 符号工作正常，只是 + 将被空格替换。

最佳答案

这是正常的 URL 编码，the plus sign is a shorthand for a space :

Within the query string, the plus sign is reserved as shorthand notation for a space. Therefore, real plus signs must be encoded. This method was used to make query URIs easier to pass in systems which did not allow spaces.

并且来自 HTML5 standard :

The character is a U+0020 SPACE character
Replace the character with a single U+002B PLUS SIGN character (+).

关于ruby-on-rails - rails : Plus sign in GET-Request replaced by space，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6464885/
