雅虎财经限制的货币汇率
我正在尝试编写一个脚本来从雅虎财经下载汇率。问题是......我找不到有关此服务的限制的任何信息。我特别感兴趣的是我查询雅虎财经以访问quotes.csv 文件的频率。如果我每分钟左右定期执行它，雅虎会杀死我的脚本吗？有谁知道我在哪里可以找到类似的雅虎官方信息？我已经找了好几个小时了，但它要么隐藏得很好，要么只是隐藏在显眼的地方而我看不到......
I'm trying to write a script that would download currency rates from yahoo finance. The problem is ... i can't find any information on the limitations of this service. Especially i'm interested in how often i can query yahoo finance to access the quotes.csv file. Would yahoo kill my script if i executed it periodically every minute or so? Does anyone know where i could find some official yahoo information of things like that? I've been searching for hours, but it's either well hidden or it's just hiding in plain sight and i don't see it...

通常它违反网站的服务条款。但是，如果您想以这种方式收集小规模的数据，那就相当简单了。我过去曾挖掘过雅虎财经，并且从未被关闭过。不要锤击该网站...将您的请求分开。如果您想更聪明地使用脚本，可以编写一个网络浏览器来为您完成此操作。页面请求将看起来相同。
Usually its against the TOS of the website. However if you want to collect data that way on a small scale it is fairly trivial. I have mined yahoo finance in the past and have never been turned off. Don't hammer the site...space out your requests. If you want to be even more clever about it script a web browser to do it for you. The page requests will then look identical.
