法拉第rails从它开始

Question

我必须显示来自这个网站的数据：https://baconipsum.com/json-api/，但我不知道在我的应用程序中的什么地方编写它的代码。我必须为控制器和视图编写什么代码？

Answer 1

设置法拉第：

bacon = Faraday.new("https://baconipsum.com/") do |f|
  f.response :json # automatically parse responses as json
end

在控制器中发送请求：

@bacon = bacon.get("api/", type: 'all-meat', sentences: 1).body # => ["Leberkas frankfurter chicken tongue."]

在视图中使用它：

<% @bacon.each do |meat| %>
  <p> 
    <%= meat %>
  </p>
<% end %>

有多种设置方法。非常简单的设置可能如下所示：

# app/controllers/application_controller.rb
class ApplicationController < ActionController::Base
  private

    # NOTE: this method will be accessible in any controller
    #       that inherits from ApplicationController
    def baconipsum
      # NOTE: memoize for a bit of performance, in case you're
      #       making multiple calls to this method.
      @baconipsum ||= Faraday.new("https://baconipsum.com/") do |f|
        f.response :json
      end
    end
end

# app/controllers/articles_controller.rb
class ArticlesController < ApplicationController
  def show
    @article = Article.find(params[:id])
    # I'm not quite sure what you're trying to do with it;
    # change this to fit your use case.
    @bacon = baconipsum.get("api/", type: 'all-meat').body
  end
end

# app/views/articles/show.html.erb
<% @bacon.each do |meat| %>
  <p> <%= meat %> </p>
<% end %>
