在Rails 3( Ruby 1.9.2)中,我发送请求

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

但参数列表如下所示：

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

这里出了什么问题？ –,*或.标志工作正常,它只会被一个空格所取代.

解决方法

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.

并从HTML5 standard：

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