Question

我正在尝试将json响应传递到erb中的索引视图中。

在ERB中我试图检查值是否为true，渲染某些html，如果为false，则渲染一些html。

路线：

require 'sinatra'
require 'httparty'
require 'erb'


get '/' do
  headers = {
    "X-Auth-Email" => 'null',
    "X-Auth-Key" =>   'null',
    "Content-Type" => 'application/json'
  }

  isDevModeOn = HTTParty.get(
    'https://api.cloudflare.com/client/v4/zones/null/settings/development_mode',
    :headers => headers
  )

  erb :index, :locals => isDevModeOn
end #end for get

          <h2>Dev Mode Status</h2>

          <% if isDevModeOn.result.value? %>
            <span style="background: green;">ON</span>

            <a href="#">Turn off Dev Mode</a>
          <% else %>
            <span style="background: red;">OFF</span>

            <a href="#">Turn On Dev Mode</a>
          <% end %>
        </div>
      </div>
    </div>
  </body>
</html>

响应示例

{
  "success": true,
  "errors": [],
  "messages": [],
  "result": {
    "id": "development_mode",
    "value": "off",
    "editable": true,
    "modified_on": "2014-01-01T05:20:00.12345Z",
    "time_remaining": 3600
  }
}

免责声明：我有一个javascript背景并且经常使用EJS而且对ruby非常缺乏经验。

将isDevModeOn作为参数传递：

require 'sinatra'
require 'httparty'
require 'erb'


get '/' do
  headers = {
    "X-Auth-Email" => 'null',
    "X-Auth-Key" =>   'null',
    "Content-Type" => 'application/json'
  }

  isDevModeOn = HTTParty.get(
    'https://api.cloudflare.com/client/v4/zones/null/settings/development_mode',
    :headers => headers
  )

  erb :index, :locals => {:isDevModeOn => params[:isDevModeOn]}
end #end for get

将变量传递给erb
