某种免费的 REST API 是理想的，但一般来说，是否有任何免费的 API 或 Web 服务或 CSV 文件(不在密码提示后面)或任何可以查询以获取当前列表的内容标准普尔 500 指数成分股?
Some sort of free REST API would be ideal, but in general is there any free API or web service or CSV file (that's not behind a password prompt) or anything out there that one can query to get the current list of the S&P 500 index constituents?
我查看了标准普尔的网站本身(http://www.standardandpoors.com)，通过 Yahoo Finance 的 API 和 Markit on demand (http://dev.markitondemand.com/)，但有还没有找到任何东西.
I've looked on S&P's site itself (http://www.standardandpoors.com), through Yahoo Finance's API, and Markit on demand (http://dev.markitondemand.com/), but have not been able to find anything yet.
