serverless-offline 基本示例没有列出或可用的路由

Question

我正在按照这个基本示例 (https://medium.com/hackernoon/tdd-means-zen-along-with-serverless-means-nirvana-a39a76ee8e63) 设置 serverless-offline 以对无服务器项目进行单元测试。

不幸的是，我无法让 serverless-offline 的初始运行正常工作。运行“serverless offline start”后，控制台输出不显示GET方法，对localhost:3000的请求只返回“Cannot GET /”。

任何想法我在这里缺少什么？提前致谢。

我的 serverless.yml：

provider:
  name: aws
  runtime: nodejs10.x
functions:
  hello:
    handler: handler.hello
    events:
      - http:
        path: ''
        method: get
plugins:
  - serverless-offline
  - serverless-mocha-plugin

我的 package.json：

  "name": "my-api",
  "version": "1.0.0",
  "description": "",
  "main": "handler.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "mongodb": "^3.3.3"
  },
  "devDependencies": {
    "serverless-mocha-plugin": "^1.11.0",
    "serverless-offline": "^5.12.0"
  }
}

我的 handler.js：

module.exports.hello = async event => {
  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'Go Serverless v1.0! Your function executed successfully!',
        input: event
      },
      null,
      2
    )
  };
};

控制台输出：

事实证明，这是我的 serverless.yml 中的缩进问题。示例博客没有在 -http 之后缩进路径、方法或 cors。感谢https://stackoverflow.com/a/58226113/296047 为我指明了正确的方向。

旁注，在重新启动计算机并从头开始尝试此博客示例后，我还收到了错误消息：

{"statusCode":404,"error":"Serverless-offline: route not found.","currentRoute":"get - /","existingRoutes":["post - /{apiVersion}/functions/my-api-prod-hello/invocations"]}

希望这可以帮助正在经历我刚刚经历的一整天故障排除的其他人。
