无法访问主机：“freetier.us-east-1.amazonaws.com”位于端口“undefined”。此服务可能在“us-east-1”区域不可用

Question

我尝试从 Lambda 函数调用 AWS 免费套餐 API，但收到此错误：

Inaccessible host: `freetier.us-east-1.amazonaws.com' at port `undefined'. This service may not be available in the `us-east-1' region.

免费层 API 文档：

https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/FreeTier.html

我的代码：

const AWS = require('aws-sdk');

module.exports = {
    getFreeTierUsage: async (awsCredential) => {
        var freetier = new AWS.FreeTier({
            accessKeyId: awsCredential.accessKeyId,
            secretAccessKey: awsCredential.secretAccessKey
        });
        var params = {};
        let result = await freetier.getFreeTierUsage(params).promise();
        return result;
    }
}

怎么了？

Answer 1

AWS 似乎正在更改其 API 的 URL 格式。

传统上它看起来像：

https://freetier.us-east-1.amazonaws.com

但是，类：AWS.FreeTier — AWS SDK for JavaScript文档将其显示为：

https://freetier.us-east-1.api.aws
