推荐答案

这是我已要求（通过AWS传道者和调查）previously，但一直没有到位。我猜AWS的人对他们的视野更有趣的创新。

This is something I have asked for (via AWS evangelists and surveys) previously, but hasn't been forthcoming. I guess the AWS folks have more interesting innovations on their horizon.

正如刚才@brokenbeatnik，对于现货价格的历史的API。 API文档在这里：<一href="http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeSpotPriceHistory.html">http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeSpotPriceHistory.html

As pointed out by @brokenbeatnik, there is an API for spot-price history. API docs here: http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribeSpotPriceHistory.html

我觉得很奇怪，现货价格历史上有一个官方的API，但是，他们并没有在同一时间进行点播服务做到这一点。总之，要回答这个问题，是可以查询的发布的AWS定价

I find it odd that the spot-price history has an official API, but that they didn't do this for on-demand services at the same time. Anyway, to answer the question, yes you can query the advertised AWS pricing...

我能想出是审查各种服务的定价页的（客户端）来源是最好的。其中你会发现，这些表是建立在JS和填充JSON数据，数据就可以得到自己。例如：

The best I can come up with is from examining the (client-side) source of the various services' pricing pages. Therein you'll find that the tables are built in JS and populated with JSON data, data that you can GET yourself. E.g.:

• <一个href="http://aws.amazon.com/ec2/pricing/pricing-on-demand-instances.json">http://aws.amazon.com/ec2/pricing/pricing-on-demand-instances.json
• <一个href="http://aws.amazon.com/s3/pricing/pricing-storage.json">http://aws.amazon.com/s3/pricing/pricing-storage.json

• http://aws.amazon.com/ec2/pricing/pricing-on-demand-instances.json
• http://aws.amazon.com/s3/pricing/pricing-storage.json

这只是成功的一半，虽然，接下来你必须选择分开的对象格式来获得你想要的值，例如，在Python这得到了Hi-CPU点播超大型Linux实例的价格为弗吉尼亚州：

That's only half the battle though, next you have to pick apart the object format to get at the values you want, e.g., in Python this gets the Hi-CPU On-Demand Extra-Large Linux Instance pricing for Virginia:

>>> import json
>>> import urllib2
>>> response = urllib2.urlopen('http://aws.amazon.com/ec2/pricing/pricing-on-demand-instances.json')
>>> pricejson = response.read()
>>> pricing = json.loads(pricejson)
>>> pricing['config']['regions'][0]['instanceTypes'][3]['sizes'][1]['valueColumns'][0]['prices']['USD']
u'0.68'

免责声明：显然，这不是一个AWS认可的API，因此我不建议期望的数据格式的稳定性，甚至继续存在的来源。但它的存在，它击败转录定价数据为静态配置/源文件！

Disclaimer: Obviously this is not an AWS sanctioned API and as such I wouldn't recommend expecting stability of the data format or even continued existence of the source. But it's there, and it beats transcribing the pricing data into static config/source files!
