Question

我正在使用以下Meteor包https://atmospherejs.com/ajbarry/yahoo-finance 使用YQL控制台并搜索＆＃34; ENW.V＆＃34;符号，我可以找回某些数据，但有些数据不起作用。这是我的模板。

    <template name="stock">
     <h2>{{stock.symbol}}</h2>
       <ul>
        <li><strong>Name</strong> {{stock.name}}</li>
        <li><strong>Ask</strong> {{stock.ask}}</li>
        <li><strong>Bid</strong> {{stock.bid}}</li>
        <li><strong>Average Daily Volume</strong> {{stock.DaysHigh}}</li>
       </ul>
    </template>

Heres是我的客户端代码：

Template.stock.rendered = function (){
  if ( _.isEmpty(Session.get('ENW.V')) ) {
    Meteor.call('getQuote', 'ENW.V', function(err, result) {
      Session.set('ENW.V', result['ENW.V']);
    });
  }
}

这是我的服务器端代码：

Template.stock.helpers({
  stock: function() {
    return Session.get('ENW.V');
  }
})

以下是json响应的示例，此处是查看它的链接here。

       }
      }

这是无效的库存数据。的 {{stock.DaysHigh}}

感谢您提前获得的任何帮助。如果需要，很乐意添加任何其他信息。

Answer 1

根据README包中的指令，如果需要超过默认值，则需要指定整个字段列表。

这是指向可用字段列表的链接：

https://github.com/pilwon/node-yahoo-finance/blob/master/lib/fields.js

YahooFinance.snapshot({symbols:['ENW.V'], fields:['s','n','g']})

g是DaysHigh符号。

使用meteor软件包从雅虎财务中获取数据，有些值不起作用
