我能够按照文档创建一个简单的无服务器功能,但是当我添加http
侦听器时,在尝试触碰端点时会不断收到502 Bad Gateway
。
我该如何调试呢?
'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

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