我这样说:
"foo=bar&bar=foo&hello=hi"
鲁比拉铁路公司是否提供穿透的方法,就像它是一种争,一样,因此,我得到的就是:
{
:foo => "bar",
:bar => "foo",
:hello => "hi"
}
还是我自己写了吗?
EDIT
请注意,以上所述并不是来自URL的真正询问,而是存放在FacebookLink的一个 co子里的扼杀。

答案取决于你使用的铁路。 如果你使用2.3或以后,则使用Rack built子管子
Rack::Utils.parse_nested_query("a=2") #=> {"a" => "2"}
如果你在旧铁路上,你确实可以使用<条码>:parse<>/code>。 请注意,处理海螺和阵列的方式在单元之间有所不同,因此,你需要核实你获得的数据是否适合你选择的方法。
也可将<代码>Rack:Utils列入您的短期访问类别。
The
CGI::parse("foo=bar&bar=foo&hello=hi")
页: 1
{"foo"=>["bar"], "hello"=>["hi"], "bar"=>["foo"]}
Edit: As specified by Ryan Long this version accounts for multiple values of the same key, which is useful if you want to parse arrays too.
Edit:
As Ben points out, this may not handle arrays well when they are formatted with ruby on rails style array notation.
The rails style array notation is: foo[]=bar&foo[]=nop
. That style is indeed handled correctly with Julik s response.
如果你有“条形码”和“foo=bar&foo=nop
<>Edit :,如评论所述,如果有人想要伤害你,则拆除钥匙可降低服务器。 在我处理低姿态时,我仍然做了很多工作,因为它使事情更容易地与大家合作,但我不会因为高利害关系而做。
不要忘记象征取得你想要的结果的关键
Rack::Utils.parse_nested_query("a=2&b=tralalala").deep_symbolize_keys
这项行动对重复工作具有破坏性。
如果你谈论正在用来获取有关参数的数据的乌拉尔
> request.url
=> "http://localhost:3000/restaurants/lokesh-dhaba?data=some&more=thisIsMore"
接下来是得出问题参数。 用途
> request.query_parameters
=> {"data"=>"some", "more"=>"thisIsMore"}
如果你想要洗衣,你可以使用
Hash[CGI::parse(x).map{|k,v| [k, v.first]}]
