雅虎财经 - 以 json 格式获取数据

Question

我想知道我应该在 YQL 中使用哪个表来获得来自 csv 的结果（符号 AAPL）。

Date,Open,High,Low,Close,Volume,Adj Close
2014-02-12,536.95,539.56,533.24,535.92,11003600,535.92
2014-02-11,530.61,537.75,529.50,535.96,10080600,535.96
2014-02-10,518.66,531.99,518.00,528.99,12341400,528.99

因为当我使用这个链接时：

http://query.yahooapis.com/v1/public/yql?q=select%20%2a%20from%20yahoo.finance.quotes%20where%20symbol%20in%20%28%22AAPL%22%29%0A%09%09&env=http%3A%2F%2Fdatatables.org%2Falltables.env&format=json

我收到了

这不一样。

http://query.yahooapis.com/v1/public/yql?q=", encodeURIComponent('select * from yahoo.finance.historicaldata where symbol in ("AAPL")') + "&env=http%3A%2F%2Fdatatables.org%2Falltables.env&format=json

似乎也不行。

Answer 1

第一个链接只提供最新的股票报价。如果我理解您的问题，您似乎想知道从哪里获取历史数据。这似乎是您需要的链接：

http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.historicaldata%20where%20symbol%20%3D%20%22AAPL%22%20and%20startDate%20%3D%20%222012-09-11%22%20and%20endDate%20%3D%20%222014-02-11%22&format=json&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=

我刚刚尝试过，它为我撤回了一个 JSON 响应，其中包含从 09-11-2012 到 02-11-2014 的历史报价。

希望这会有所帮助。
