首页 > 解决方案 > Lambda 代码适用于 node v8.10 但不适用于 nodejs v10.x

问题描述

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,因为这是我将来想在我的项目中使用的。

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"
    });
};

解决方案


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 版本现在已被弃用,它可能仍然被接受)。

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'
