当我尝试使用SAM定义的GET端点时,总是得到500 Internal Server Error
。
我能够定义一个有效的POST请求。
对于GET请求,它向我显示:
Lambda invocation failed with status: 403
Execution failed due to configuration error:
我认为在定义API网关的DefinitionBody时出现了问题。
Globals:
Api:
Cors:
AllowMethods: "'GET,POST,OPTIONS'"
AllowHeaders: "'DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range'"
AllowOrigin: "'*'"
Resources:
getFunction:
Type: 'AWS::Serverless::Function'
Properties:
...
Events:
GetApi:
Type: Api
Properties:
Path: /tips
Method: GET
RestApiId: !Ref MyApi
MyApi:
Type: AWS::Serverless::Api
Properties:
StageName: dev
EndpointConfiguration: REGIONAL
DefinitionBody:
swagger: "2.0"
info:
title: "API"
paths:
/tips:
get:
x-amazon-apigateway-integration:
uri:
Fn::Sub: arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${getFunction.Arn}/invocations
responses: {}
httpMethod: "POST"
type: "aws_proxy"
我已经尝试过将x-amazon-apigateway-integration上的httpMethod更改为“ GET”,但这不能解决我的问题。
在AWS Lambda控制台中,我看到Lambda和Api网关已链接,但是我无法通过API网关调用Lambda。我可以在控制台中通过“测试事件”成功执行Lambda。绝对是API网关方面的东西。
有人可以验证我在做什么吗?
答案 0 :(得分:0)
进一步研究之后,我发现必须实现GET
路径的/tips
方法,如下所示:
get:
responses:
'200':
description: 200 response
headers:
Content-Type:
type: string
produces:
- application/json
x-amazon-apigateway-integration:
uri:
Fn::Sub: "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${getTipsFunction.Arn}/invocations"
passthroughBehavior: when_no_match
responses:
default:
statusCode: 200
responseParameters:
method.response.header.Content-Type: integration.response.header.content-type
httpMethod: POST
type: aws
这解决了问题。
