如何在Rails中创建一个应用程序,让我输入搜索参数,然后将这些参数传递给外部API进行搜索,然后在我的应用程序中显示这些结果。我正在尝试使用HTTParty来实现这一目标,但我有点迷茫。我尝试在app / services中创建一个类方法,并在控制器中访问它,然后在我的视图中调用实例变量。目前,它引发了路由错误uninitialized constant ResultsController::Api
。非常感谢您的帮助。
services / Api.rb
class Api
include HTTParty
base_uri "search.example.com"
attr_accessor :name
def initialize(name)
self.name = name
end
def self.find(name)
response = get("/results&q=#{name}")
self.new(response["name"])
end
results_controller.rb
class ResultsController < ApplicationController
include Api
def index
@results = Api.find('test')
end
end
路线:
Rails.application.routes.draw do
resources :results
root 'results#index'
end

您几乎是正确的,只需在此处进行一些更改。首先,将Api.rb
重命名为api.rb
-按照惯例,所有文件都应使用小蛇名命名。
class Api
include HTTParty
base_uri "http://search.spoonflower.com/searchv2"
def find(name)
self.class.get("/designs", query: { q: name }).parsed_response
end
end
class ResultsController < ApplicationController
def index
# here you get some json structure that you can display in the view
@results = Api.new.find('test')['results']
end
end
