Question

我正在使用AWS boto3定价api获取实例的价格。

但是我没有得到组合的结果（美国西部2，r3.2x大，Linux，未安装预软件，租户=共享）

这是我的代码：

pricing = boto3.client('pricing', region_name='us-east-1')
hourlyTermCode = 'JRTCKXETXF'
rateCode = '6YS6EN2CT7'
token = ''
while True:
    paginator = pricing.get_paginator('get_products')
    pages = paginator.paginate(
        ServiceCode='AmazonEC2',
        Filters=[
            {'Type': 'TERM_MATCH', 'Field': 'operatingSystem', 'Value': 'Linux'},
            {'Type': 'TERM_MATCH', 'Field': 'location', 'Value': 'US West (Oregon)'}

        ],

        PaginationConfig={
            'StartingToken':token
        }
    )

    for response in pages:
        for price in response['PriceList']:
            resp = json.loads(price)
            product = resp['product']  # ['attributes']['']
            sku = product['sku']

            if product['productFamily'] == 'Compute Instance':
                if str(product['attributes']['instanceType']) == str(amazon_instance_type) :
                    if str(product['attributes']['operatingSystem']) == 'Linux':
                        if str(product['attributes']['preInstalledSw']) == 'NA':
                            if str(product['attributes']['tenancy']) == 'Shared':
                                sku_key = resp['terms']['OnDemand'].get(sku)
                                if sku_key:
                                    price = sku_key[sku + '.' + hourlyTermCode + '.' + rateCode]['pricePerUnit']['USD']
                                    print 'here 7'
                                    print price

        try:
            token = response['NextToken']
        except KeyError:
            pass

Answer 1

这有效：

import json
import boto3

client = boto3.client('pricing', region_name='us-east-1')

response = client.get_products(
    ServiceCode='AmazonEC2',
    Filters=[
        {'Type': 'TERM_MATCH', 'Field': 'operatingSystem', 'Value': 'Linux'},
        {'Type': 'TERM_MATCH', 'Field': 'location', 'Value': 'US West (Oregon)'},
        {'Type': 'TERM_MATCH', 'Field': 'instanceType', 'Value': 'r3.2xlarge'},
        {'Type': 'TERM_MATCH', 'Field': 'tenancy', 'Value': 'Shared'},
        {'Type': 'TERM_MATCH', 'Field': 'preInstalledSw', 'Value': 'NA'}
    ]
)

for pricelist_json in response['PriceList']:
    pricelist = json.loads(pricelist_json)
    product = pricelist['product']

    if product['productFamily'] == 'Compute Instance':
        print pricelist['terms']['OnDemand'].values()[0]['priceDimensions'].values()[0][u'pricePerUnit']['USD']

它基于以下内容的输出：

AWS Pricing API不会根据给定的搜索条件产生价格
