我有一个要求,用户可以用这种格式传递网址:

http:site.com/[action]/[subject]?[option]=[value]

例如以下所有内容都是有效的网址:

http://example.com/trigger/a/b/c
http://example.com/trigger/a
http://example.com/trigger/a/b?something=value
http://example.com/trigger/any/thing/goes/here

我有grape这样的资源:

class Test < Grape::API
  params do
    optional :option, type: String
  end

  get '/trigger/:a/:b/:c' do
    {
      type: 'trigger',
      a: params[:a],
      b: params[:b],
      c: params[:c],
      option: params[:option]
    }
  end
end

所以,如果我访问http://example.com/1/2/3/option=something,那么我会得到

{
  "type": "trigger",
  "a": "1",
  "b": "2",
  "c": "3",
  "option": "something"
}

预期行为:

使用应该能够在/trigger/

之后提供任何内容
http://example.com/any/thing/goes/here/1/2/3?other=value&goes=here

更新

我找到了针对rails路由的此解决方案(How do we identify parameters in a dynamic URL?),我想在grape中使用此行为。

答案 0 :(得分:0)

嗯,实际上我正在寻找wildcards

matching params
get "trigger/*subject" do
  {
    params: params[:subject]
  }
end

现在它将响应路径:

curl http://example.com/trigger/subject/can/be/anything

输出:

{
 params: "subject/can/be/anything"
}
