Ruby on Rails：解码来自 url 的参数

Question

I begin to create a rails API for react. I pass a GET request with params inside url like this:

api/dashboard/price?"foo"="bar"

But my rails app by default cannot decode it properly and on backend side. My params object looks this way:

<ActionController::Parameters {"\"foo\""=>"\"bar\"", "controller"=>"api/dashboards", "action"=>"price"} permitted: false>

Furthermore I cannot access any of those keys eg:

params[:foo]

returns nil

How can I get rid of those slashes and decode url params proper way?

If you want to pass url params with quotes "foo" then you should also access them with quotes like this: params['"foo"'] .

But if you want to make params[:foo] work then just pass them without any quotes. api/dashboard/price?foo=bar .
