AWS CloudFormation/API Gateway 提供'Invalid Resource identifier specified'

Question

我一直在尝试使用CloudFormation部署到API Gateway，但是，我经常使用方法资源遇到同一问题。堆栈部署不断失败，"指定的无效资源标识符"。

这是我的云形式模板的方法资源：

"UsersPut": {
        "Type": "AWS::ApiGateway::Method",
        "Properties": {
            "ResourceId": "UsersResource",
            "RestApiId": "MyApi",
            "ApiKeyRequired": true,
            "AuthorizationType": "NONE",
            "HttpMethod": "PUT",
            "Integration": {
                "Type": "AWS_PROXY",
                "IntegrationHttpMethod": "POST",
                "Uri": {
                    "Fn::Join": ["", ["arn:aws:apigateway:", {
                        "Ref": "AWS::Region"
                    }, ":lambda:path/2015-03-31/functions/", {
                        "Fn::GetAtt": ["MyLambdaFunc", "Arn"]
                    }, "/invocations"]]
                }
            },
            "MethodResponses": [{
                "StatusCode": 200
            }]
        }
    }

有人能帮助我弄清楚为什么这会使堆栈部署失败吗？

更新：我忘了提到我也尝试使用参考来添加资源ID，这也给了我相同的错误：

"UsersPut": {
        "Type": "AWS::ApiGateway::Method",
        "Properties": {
            "ResourceId": {
                "Ref": "UsersResource"
            },
            "RestApiId": "MyApi",
            "ApiKeyRequired": true,
            "AuthorizationType": "NONE",
            "HttpMethod": "PUT",
            "Integration": {
                "Type": "AWS_PROXY",
                "IntegrationHttpMethod": "POST",
                "Uri": {
                    "Fn::Join": ["", ["arn:aws:apigateway:", {
                        "Ref": "AWS::Region"
                    }, ":lambda:path/2015-03-31/functions/", {
                        "Fn::GetAtt": ["MyLambdaFunc", "Arn"]
                    }, "/invocations"]]
                }
            },
            "MethodResponses": [{
                "StatusCode": 200
            }]
        }
    }

Answer 1

ResourceID必须是对云形式资源的引用，而不是简单的字符串。

，例如

  ResourceId:
    Ref: UsersResource

Answer 2

我认为实际上是RESTAPIID，也需要是参考：

            "RestApiId": {
                "Ref": "MyApi"
            },

Answer 3

创建API资源(1(时，为路径/创建了API的默认根资源(2(。为了获得Myapi资源的ID(1(根资源(2(使用：

"ResourceId": {
  "Fn::GetAtt": [
    "MyApi",
    "RootResourceId"
  ]
}

(1(堆栈资源(2(API资源

Answer 4

尝试

  {
    "$ref": "https://apigateway.amazonaws.com/restapis/YOUR_API_GATEWAY_IT/models/YOUR_MODEL_NAME"
  }

此外，您还可以通过将该模型的URL设置为$ ref属性的值来引用在外部模型文件中定义的另一个模型架构：'$ ref＆quot'：＆quort" https：//apigateway.amazonaw.com/restapis/{restapi_id}/models/{model_name}＆quort＆quort。
