我将 .env 文件配置为具有 AWS 凭证，但它不起作用。

在文档中，配置将自动从 .env 文件加载。但事实并非如此。

我尝试添加以下内容

    aws.config.update({
    region: process.env.AWS_region,
    accessKeyId: process.env.AWS_ACCESS_KEY_ID,
    secretAccessKey: process.env.AWS_SECRET_ACCESS_KEY,
});

这奏效了。

知道为什么 AWS SDK 不自动加载选项吗？

"aws-sdk": "^2.288.0",
"dotenv": "^6.0.0",

我有以下项目树

其中nodejs文件夹是以下serverless.yaml中定义的lambda层

service: aws-nodejs # NOTE: update this with your service name


provider:
  name: aws
  runtime: nodejs8.10
  stage: dev

plugins:
  - serverless-offline
layers:
  layer1:
    path: nodejs # required, path to layer contents on disk
    name: ${self:provider.stage}-layerName # optional, Deployed Lambda layer name

functions:
  hello:
    handler: handler.hello
    layers:
      - {Ref: Layer1LambdaLayer}
    events:
      - http:
          path: /dev
          method: get

layer1仅包含UUID软件包。

因此，当我尝试使用无服务器脱机插件在本地运行lambda时，它说找不到模块UUID。

但是，当我将代码部署到AWS时，它的运行就像一个魅力。

有什么办法可以让Lambda层在本地运行以进行测试？为了加快发展？

还是有什么方法可以在开发过程中动态设置node_module路径以指向图层文件夹，一旦我需要进行生产，它将路径更改为正确的路径

我需要启用全局方法安全性.

问题是当我添加注释时@EnableGlobalMethodSecurity(prePostEnabled = true)- 我收到如下错误:

我正在尝试使用以下查询获取按月分组的唯一产品视图

SELECT
  Month(timestamp)           AS 'month',
  COUNT(DISTINCT visitor_id) AS 'unique'
FROM productviews pv INNER JOIN products p ON pv.product_id = p.id
WHERE p.vendor_id = 8 AND YEAR(timestamp) = 2018
GROUP BY month(timestamp);

我正在接受

+---------+--------+
| month   | unique |
+---------+--------+
|    1    |  3     |
+---------+--------+
|    2    |  10    |
+---------+--------+
|    3    |  2     |
+---------+--------+
|    4    |  4     |
+---------+--------+

但唯一产品视图的总数小于上一个查询的总和

SELECT count(DISTINCT pv.visitor_id)
FROM productviews pv INNER JOIN products p ON pv.product_id = p.id
WHERE p.vendor_id …

我正在使用无服务器框架以及 lambda 层和几个 lambdas 函数。我必须包含 aws-sdk 才能支持某些功能。

aws-sdk 的 lambda 层大小为 80MB，而 aws-sdk 单独占用 40MB。

我所知道的是 Lambda 函数默认包含 aws-sdk。但这是否也意味着 lambda 层？

笔记

• 我尝试删除 aws-sdk 并部署，并且 lambda 函数显示错误“找不到模块 aws-sdk”
• NODE_PATH: "./:/opt/node_modules" 包含在 serverless.yml 中（这是否会导致默认情况下不包含 aws-sdk）？
• 运行时是 nodejs10.x
