Question

我正在使用AWS Pricing API：

http://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/price-changes.html

问题是它有像

这样的数据

"KV46EU5KJGKB53ZX" : {
  "sku" : "KV46EU5KJGKB53ZX",
  "productFamily" : "Compute Instance",
  "attributes" : {
    "servicecode" : "AmazonEC2",
    "location" : "US East (N. Virginia)",
    "locationType" : "AWS Region",

我不知道如何将locationType和location与我用于启动EC2实例的数据相关联（例如在us-east-1中）。

有没有办法知道启动EC2实例的成本？

Answer 1

我不知道价格表API提供的结构中是否存在此交叉引用/映射数据，但遗憾的是，EC2 API中的DescribeRegions并未提供此数据。

但是，它可以在一般文档下的Regions and Endpoints页面上找到。从该信息中，您可以构建一个简单的字典或查找表。

Answer 2

只需自己构建即可。我知道它不会被更新，但是...

注意：我从AWS定价用户界面中提取的此列表中缺少中国

Answer 3

我建议使用jq来处理大型json文档。例如，对于sku KV46EU5KJGKB53ZX的OnDemand定价：

int solver(int num) //gets an integer
{
    string numString = to_string(num); //convert integer to string so i can manipulate individual digits
    int divisible=0; //will store a count of digits in "num" which can be divided evenly

    for (int x = 1; x <= (end(numString) - begin(numString))/*string length*/; x++)
    {

        if (numString[x-1] == 0 || (end(numString) - begin(numString))-x >=1) //ignore digits which are 0 and or 0s that are last in the array
            ++x;

        if (num % numString[x - 1] == 0) //THIS NEVER EVALUATES TO TRUE. HOW COME???
            divisible++; 

    }
    return divisible;  //number of digits in variable "num" which can be evenly divided
}
