Golang 取得AWS產品價格資訊

Go以AWS提供的SDK aws-sdk-go-v2來取得AWS服務的產品價格資訊。

事前要求

參考「AWS 建立IAM管理使用者及credentials」設定供應用程式存取AWS需要的credentials。

參考「Golang 取得AWS Pricing ServiceCode」取得要查詢產品的服務代碼(ServiceCode)。

取得產品資訊

呼叫pricing.Client.GetProducts傳入參數pricing.GetProductsInput取得服務的產品列表。

在pricing.GetProductsInput參數欄位，

• ServiceCode - 輸入查詢產品的服務代碼。例如EC2的服務代碼為AmazonEC2
• MaxResults - 最大輸出結果筆數。
• Filters - 輸入types.Filter陣列，用來篩選符合條件的結果。Field為要篩選的欄位名稱；Value為刪選欄位的值。例如範例只篩選輸出結果中欄位sku值為7UV2VKCDN6WVVP54的結果。

main.go

package main

import (
    "context"
    "fmt"

    "github.com/aws/aws-sdk-go-v2/aws"
    "github.com/aws/aws-sdk-go-v2/config"
    "github.com/aws/aws-sdk-go-v2/service/pricing"
    "github.com/aws/aws-sdk-go-v2/service/pricing/types"
)

func main() {
    ctx := context.TODO()
    client := NewPricingClient(ctx)

    serviceCode := "AmazonEC2"
    out, err := client.GetProducts(ctx, &pricing.GetProductsInput{
        ServiceCode: &serviceCode,
        MaxResults:  aws.Int32(2),
        Filters: []types.Filter{
            {
                Field: aws.String("sku"),
                Type:  "TERM_MATCH",
                Value: aws.String("7UV2VKCDN6WVVP54"),
            },
        },
    })
    if err != nil {
        panic(err)
    }

    for _, price := range out.PriceList {
        fmt.Println(price)
    }
}

func NewPricingClient(ctx context.Context) *pricing.Client {
    cfg, err := config.LoadDefaultConfig(
        ctx,
        config.WithRegion("ap-south-1"),
    )
    if err != nil {
        panic(err)
    }

    return pricing.NewFromConfig(cfg) // Create an Pricing service client
}

測試

執行Go應用程式輸出以下結果，為JSON字串表示的產品資訊（因為使用欄位sku篩選，所以只會有一筆）。
