我正在尝试使用 homeaway API 在 html 页面上显示一些数据。

我的 search_results 文件看起来像这个 priceRanges=[#, #, #] 而不是我想要的 3 个价格。

我在网上查看了转换为整数的方法，但这无济于事。我只是想知道这个数字是否已从服务器中扣留/我的堆栈/代码有问题，因为老实说我已经搜索了几个小时但一无所获。

这是我的代码

搜索结果

<html>
  <head>
    <title>Search results for <%= "#{session[:me].first_name} #{session[:me].last_name}" %></title>
  </head>
  <body>
    <h3>Search results for <%= "#{session[:me].first_name} #  {session[:me].last_name}" %></h3>
    <br/>

    <%   end %></p>
    <p>Here are your search results:
      <ul>
        <% @search_results.each do |result| %>
          <li>
            <% if result.has?(:thumbnail) %>
              <img src="<%= result.thumbnail.secureUri %>"/>
            <% end %>
            <p><%= result %></p>
            <p>Price Range: <% a = result.priceRanges.to_a
              b = a.at(1).to_i
            %></p>
            <p><%= "#{b}" %>
            <p>Bedrooms: <%= result.bedrooms %></p>
            <p>Bathrooms: <%= result.bathrooms %></p>
            <p>Amount: <% puts result.amount %> <% result.currency %></p>
            <a href="/listing/<%= result.listingId %>"><%= result.headline %></a>
            <a href="<%=result.listingUrl %>">View on Homeaway</a>
            <p><%= result.Latitude %></p>
            <p><%= result.displayLongitude %></p>    </li>
        <% end %>
      </ul>

      <br/><br/>
      <a href="/">go back</a>
    </body>
  </html>
