我想从 serverless-offline 中的另一个 lambda 调用一个 lambda。我想制作一个无服务器的离线 Web 应用程序。但是我收到了这个错误：

sls-api-dev-你好

'use strict';

module.exports.hello = async event => {
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'Welcome to Serverless',
        input: event,
      },
      null,
      2
    ),
  };

  // Use this code if you don't use the http event with the LAMBDA-PROXY integration
  // return { message: 'Go Serverless v1.0! Your function executed successfully!', event };
};

请帮助，任何帮助都会很棒，因为我是无服务器的新手。在此先感谢。

您应该在此处更改的唯一内容是lambda 实例配置中的端点以指向基本无服务器离线url。此外，您根本不需要使用serverless -offline-lambda pluing。

将 Lambda 选项更改为如下所示：

const lambda = new AWS.Lambda({
  region: "ap-south-1",
  endpoint: process.env.IS_OFFLINE ? "http://localhost:3000" : "https://lambda.ap-south-1.amazonaws.com",
});

此外，这意味着什么

process.env.IS_OFFLINE

? 意味着您使用serverless-offline插件在本地运行 lambda，该插件实际上设置了这个 env 变量。
