雅虎财经 API [关闭]

【中文标题】雅虎财经 API [关闭]【英文标题】：Yahoo Finance API [closed] 【发布时间】：2009-11-19 13:30:13 【问题描述】：问。雅虎是否提供任何金融 API？如果是，该 API 的链接是什么。
【问题讨论】：
另外，请考虑合并财务数据 API：mergent.com/servius 您可以使用免费 API jarloo.com/yahoo_finance获取最多 200 个符号的 CSV 文件 @DaveWebb Google 的 Finance API 已被弃用，将于 2012 年 10 月停止使用：( Google Finance API 现已弃用... :( 不管有什么价值，我都会尝试更新财务 API 的here 列表。截至 2013 年 8 月 26 日，雅虎和谷歌似乎都有可用的 API，尽管我不知道它们的许可。 【参考方案1】：恕我直言，查找此信息的最佳位置是： http://code.google.com/p/yahoo-finance-managed/
我也曾经使用过“gummy-stuff”，但后来我发现这个页面更有条理，并且充满了易于使用的示例。我现在使用它来获取 CSV 文件中的数据并在我的 C++/Qt 项目中使用这些文件。

【参考方案2】：这是我在 c# 中创建的一个简单的刮板，用于将流式报价数据打印到控制台。它应该很容易转换为java。基于以下帖子：

不太花哨（即没有正则表达式等），只是一个快速而肮脏的解决方案。

【讨论】：
您无需抓取即可获取数据。有一个完整的 API 可以为您提供漂亮的 CSV 文件：jarloo.com/yahoo_finance 据我所知，JarLoo api 使用 Yahoo Finance 的 quotes.csv 端点，它不是流数据。上面的代码专门做实时报价数据的流式传输，没有轮询。 YQL 有一个实验性的流 API，但它在后台进行轮询【参考方案3】：您可以使用 YQL，但 yahoo.finance.* 表不是核心 yahoo 表。它是一个使用“csv api”并将其转换为 json 或 xml 格式的开放数据表。它使用起来更方便，但并不总是可靠的。我刚才无法使用它，因为它的表达到了存储限制或其他什么...
您可以使用这个 php 库来使用 YQL 获取历史数据/报价 https://github.com/aygee/php-yql-finance

【参考方案4】：Yahoo 非常易于使用并提供自定义数据。使用以下页面了解更多信息。
finance.yahoo.com/d/quotes.csv?s=AAPL+GOOG+MSFT=pder=.csv
警告 - 网络上有一些教程向您展示如何执行此操作，但如果您按照发布的方式使用股票代码所在的区域，则会导致错误。您将获得“缺少格式值”。我发现的教程省略了关于 GOOG 的评论。
GOOG 的示例网址： http://download.finance.yahoo.com/d/quotes.csv?s=%40%5EDJI,GOOG&f=nsl1op&e=.csv
