ruby - Grape 中的多个路由参数

Question

如何让 Grape 中的多个路由参数在 grape 中工作？

我可以使这条路线可行:

.../api/company/:cid

但是当我尝试这样做时:

.../api/company/:cid/members
.../api/company/:cid/members/:mid

我收到错误。

这是有效的代码。

resource 'company' do
params do
    optional :start_date, type: Date, desc: "Start date of range."
    optional :end_date, type: Date, desc: "End date of range."
end 
route_param :cid do
    get do
        {company_id: params[:cid]}
    end
end

class API::Company < Grape::API
  resource :company do
     route_param :cid do
        desc "GET"
        params do
          # your params
        end
        get '/' do  # => '.../api/company/:cid
          # process get
        end


        resources :members do
          desc "GET"
          params do
            # your params
          end
          get '/' do  # => '.../api/company/:cid/members/'
             # process get
          end


          route_param :mid do
            desc "GET"
            params do
              # your params
            end
            get '/' do # => '.../api/company/:cid/members/:mid'
              # process get
            end
          end
        end
     end
  end
end

你可以那样做。或者您可以创建两个不同的资源文件并将成员挂载到公司。像这样:

# api/company.rb
class API::Company < Grape::API
  resource :company do
     route_param :cid do
        desc "GET"
        params do
          # your params
        end
        get '/' do  # => '.../api/company/:cid
          # process get
        end


        mount API::Members
     end
  end
end

# api/member.rb
class API::Member < Grape::API
  resources :members do
    desc "GET"
    params do
      # your params
    end
    get '/' do  # => '.../api/company/:cid/members/'
      # process get
    end


    route_param :mid do
    desc "GET"
    params do
      # your params
    end
    get '/' do # => '.../api/company/:cid/members/:mid'
      # process get
    end
  end
end
