Lambda 代码适用于 node v8.10 但不适用于 nodejs v10.x

Question

我正在学习使用 v8.10 完成的 lambda 课程。我正在尝试使用 nodejs v10.x，因为这是我将来要用于我的项目的内容。

我不明白为什么“const uuid = require('uuid');” 行仅在 nodejs v10 中引发导入错误，但在 v8.10 中代码运行得很好。

代码：

const aws = require('aws-sdk');
const s3 = new aws.S3();
const uuid = require('uuid');

exports.handler = async (event) => {
    console.log("Get the event to our S3POC class - " + JSON.stringify(event));

    const newUUID = uuid.v4();

    console.log("The file name is:" + newUUID);

    //put our sentence into the s3 bucket
    return s3.putObject({
        Bucket: "helloworld-s3.arkhadbot.com",
        Key: "test" + ".json"
    });
};

错误

Answer 1

由于 node.js v10 aws lambda 不支持从 lambda 本身导入库。

从文档：

部署包是一个 ZIP 存档，其中包含您的函数代码和依赖项。如果您使用 Lambda API 管理函数，或者需要包含除 AWS 开发工具包之外的库和依赖项，则需要创建部署包。

如果您的函数依赖于 SDK for JavaScript 以外的库，请使用 NPM 将它们安装到本地目录，并将它们包含在您的部署包中。如果您需要比运行时中包含的版本更新的版本，或者确保该版本在未来不会更改，您还可以包含适用于 JavaScript 的 SDK。

2020 年 2 月 5 日更新：

node.js 8.10 现在已弃用，您应该使用 node.js 10 或 12。

Answer 2

根据接受的答案，现在要求 lambda 不会直接获得第三方支持。（因为 Node 8 版本现在已弃用，但可能仍被接受）。

const aws = require('aws-sdk');
const s3 = new aws.S3();
// const uuid = require('uuid'); comment this out

exports.handler = async (event, context) => {
    console.log("Get the event to our S3POC class - " + JSON.stringify(event));

    // const newUUID = context.awsRequestId();
    const newUUID = context.awsRequestId;

    console.log("The file name is:" + newUUID);

    //put our sentence into the s3 bucket
    return s3.putObject({
        Bucket: "helloworld-s3.arkhadbot.com",
        Key: "test" + ".json"
    });
};

AWS 请求 ID 可能如下所示： requestId: 'daf9dc5e-1628-4437-9e2d-2998efaa73b4'
