Preparations

In this step, we do some preparations steps to create REST APIs later.

  1. Open template.yaml in fcj-book-shop folder.

  2. Add the following script at the end of the file.

    • Firstly, we will create apiType, binaryMediaType and getOrPostPathPart parameters.

      apiType:
  Type: String
  Default: REGIONAL

binaryMediaType:
  Type: String
  Default: multipart/form-data

getOrPostPathPart:
  Type: String
  Default: books

deletePathPart:
  Type: String
  Default: "{id}"

      PrepRestApi

    • Next, we will create BookApi RestApi and BookApiResource Resource.

      BookApi:
  Type: AWS::ApiGateway::RestApi
  Properties:
    Name: fcj-serverless-api
    EndpointConfiguration:
      Types:
        - !Ref apiType
    BinaryMediaTypes:
      - !Ref binaryMediaType

BookApiResource:
  Type: AWS::ApiGateway::Resource
  Properties:
    RestApiId: !Ref BookApi
    ParentId: !GetAtt BookApi.RootResourceId
    PathPart: !Ref getOrPostPathPart

BookDeleteApiResource:
  Type: AWS::ApiGateway::Resource
  Properties:
    RestApiId: !Ref BookApi
    ParentId: !Ref BookApiResource
    PathPart: !Ref deletePathPart

      PrepRestApi

  3. Run the following command to deploy SAM.

    sam build
sam validate
sam deploy

    PrepRestApi

  4. Open AWS API Gateway console.

    • Click fcj-serverless-api REST api. PrepRestApi
    • At fcj-serverless-api resources page.
      • Click Resources.
      • Select /books.
      • Check Resource details information. PrepRestApi
      • Select /{id}.
      • Check Resource details information. PrepRestApi
      • Click API settings.
      • Check multipart/form-data Media type at Binary media types. PrepRestApi

So we finish some preparation steps. Next, we will create GET, POST and DELETE api.
