我能够按照文档创建一个简单的无服务器函数,但是当我添加http侦听器时,我在尝试访问端点时总是得到一个502 Bad Gateway。
我如何调试它呢?
'use strict';
module.exports.hello = async (event, context) => {
return {
statusCode: 200,
body: {
message: 'Go Serverless v1.0! Your function executed successfully!',
input: event,
},
};
};serverless.yaml
service: playing-with-serverless # NOTE: update this with your service name
provider:
name: aws
runtime: nodejs8.10
functions:
hello:
handler: handler.hello
events:
- http:
path: hello
method: get我已经部署了我的函数

您需要在响应对象中对body进行字符串化:
return {
statusCode: 200,
body: JSON.stringify({
message: 'Go Serverless v1.0! Your function executed successfully!',
input: event
})
};具体地说是See docs Output Format of a Lambda Function for Proxy Integration

您的服务器端代码中可能存在错误。
尝试在AWS控制台上测试您的请求。它会准确地指出Javascript代码中的错误(如果有错误)。
