在Rails中显示来自API的搜索栏查询结果

class SearchController < ApplicationController
  def index
    @results = []
    if params[:query]
      response = HTTParty.get("https://api.example.com/search?q=#{params[:query]}")
      @results = JSON.parse(response.body)['results']
    end
  end
end

<!-- app/views/search/index.html.erb -->
<%= form_tag search_path, method: :get do %>
  <%= text_field_tag :query, params[:query] %>
  <%= submit_tag 'Search' %>
<% end %>

<% if @results.any? %>
  <ul>
    <% @results.each do |result| %>
      <li><%= result['title'] %></li>
    <% end %>
  </ul>
<% else %>
  <p>No results found.</p>
<% end %>

class SearchController < ApplicationController
  def index
    @results = []
    begin
      if params[:query]
        response = HTTParty.get("https://api.example.com/search?q=#{params[:query]}")
        @results = JSON.parse(response.body)['results']
      end
    rescue StandardError => e
      logger.error "API request failed: #{e.message}"
      # 设置默认值或显示错误信息
      @results = [{ title: 'Error fetching data. Please try again later.' }]
    end
  end
end
