我正在尝试从API网关端点配置为网站的S3存储桶。我使用控制台成功配置了一个端点,但是我无法使用CloudFormation重新创建配置。
经过大量的反复试验和猜测,我想出了以下CF堆栈模板,使我非常接近:
Resources:
Api:
Type: 'AWS::ApiGateway::RestApi'
Properties:
Name: ApiDocs
Resource:
Type: 'AWS::ApiGateway::Resource'
Properties:
ParentId: !GetAtt Api.RootResourceId
RestApiId: !Ref Api
PathPart: '{proxy+}'
RootMethod:
Type: 'AWS::ApiGateway::Method'
Properties:
HttpMethod: ANY
ResourceId: !GetAtt Api.RootResourceId
RestApiId: !Ref Api
AuthorizationType: NONE
Integration:
IntegrationHttpMethod: ANY
Type: HTTP_PROXY
Uri: 'http://my-bucket.s3-website-${AWS::Region}.amazonaws.com/'
PassthroughBehavior: WHEN_NO_MATCH
IntegrationResponses:
- StatusCode: 200
ProxyMethod:
Type: 'AWS::ApiGateway::Method'
Properties:
HttpMethod: ANY
ResourceId: !Ref Resource
RestApiId: !Ref Api
AuthorizationType: NONE
RequestParameters:
method.request.path.proxy: true
Integration:
CacheKeyParameters:
- 'method.request.path.proxy'
RequestParameters:
integration.request.path.proxy: 'method.request.path.proxy'
IntegrationHttpMethod: ANY
Type: HTTP_PROXY
Uri: 'http://my-bucket.s3-website-${AWS::Region}.amazonaws.com/{proxy}'
PassthroughBehavior: WHEN_NO_MATCH
IntegrationResponses:
- StatusCode: 200
Deployment:
DependsOn:
- RootMethod
- ProxyMethod
Type: 'AWS::ApiGateway::Deployment'
Properties:
RestApiId: !Ref Api
StageName: dev
使用此模板,我可以成功获得存储桶网站的根源,但是代理资源为我提供了500:
curl -i https://abcdef.execute-api.eu-west-1.amazonaws.com/dev/index.html
HTTP/1.1 500 Internal Server Error
Content-Type: application/json
Content-Length: 36
Connection: keep-alive
Date: Mon, 11 Dec 2017 16:36:02 GMT
x-amzn-RequestId: 6014a809-de91-11e7-95e4-dda6e24d156a
X-Cache: Error from cloudfront
Via: 1.1 8f6f9aba914cc74bcbbf3c57e10df26a.cloudfront.net (CloudFront)
X-Amz-Cf-Id: TlOCX3eemHfY0aiVk9MLCp4qFzUEn5I0QUTIPkh14o6-nh7YAfUn5Q==
{"message": "Internal server error"}
我不知道该如何调试500。
要跟踪可能出了什么问题,我已经将aws apigateway get-resource
的输出与我在控制台(正在工作)中手动创建的资源上的输出进行了比较,并将一个云形式(不是)进行了比较。资源看起来完全一样。但是, get-method
的输出略有不同,我不确定是否可以使用云形式使它们完全相同。
工作方法配置:
{
"apiKeyRequired": false,
"httpMethod": "ANY",
"methodIntegration": {
"integrationResponses": {
"200": {
"responseTemplates": {
"application/json": null
},
"statusCode": "200"
}
},
"passthroughBehavior": "WHEN_NO_MATCH",
"cacheKeyParameters": [
"method.request.path.proxy"
],
"requestParameters": {
"integration.request.path.proxy": "method.request.path.proxy"
},
"uri": "http://muybucket.s3-website-eu-west-1.amazonaws.com/{proxy}",
"httpMethod": "ANY",
"cacheNamespace": "abcdefg",
"type": "HTTP_PROXY"
},
"requestParameters": {
"method.request.path.proxy": true
},
"authorizationType": "NONE"
}
不起作用的配置:
{
"apiKeyRequired": false,
"httpMethod": "ANY",
"methodIntegration": {
"integrationResponses": {
"200": {
"responseParameters": {},
"responseTemplates": {},
"statusCode": "200"
}
},
"passthroughBehavior": "WHEN_NO_MATCH",
"cacheKeyParameters": [
"method.request.path.proxy"
],
"requestParameters": {
"integration.request.path.proxy": "method.request.path.proxy"
},
"uri": "http://mybucket.s3-website-eu-west-1.amazonaws.com/{proxy}",
"httpMethod": "ANY",
"requestTemplates": {},
"cacheNamespace": "abcdef",
"type": "HTTP_PROXY"
},
"requestParameters": {
"method.request.path.proxy": true
},
"requestModels": {},
"authorizationType": "NONE"
}
差异:
- 工作配置的
responseTemplates
设置为"application/json": null
。据我所知,没有办法使用CloudFormation将映射明确地设置为null
。我的CF方法相反,这里只有一个空的对象。 - 我的CF方法具有
"responseParameters": {},
,而工作配置根本没有responseParameters
- 我的CF方法具有
"requestModels": {},
,而工作配置根本没有requestModels
比较游戏机中的两者,它们似乎完全相同。
我的智慧在这里结束:我在做什么错?这可以使用云形式实现吗?
答案:以上是正确的。我通过一系列步骤达到了这个解决方案,并一遍又一遍地重新应用模板。删除堆栈并使用此配置重新部署它具有所需的效果。
