GET a book record by it's ID

[GaProgMan]

Description

The current version of the API returns a single, hardcoded book record for all GET requests sent to the /Books endpoint. This should be altered, such that the /Books endpoint takes an ID for the book to return.

High-Level Proposed Solution

• Alter the Get method of the BooksController to take a GUID
• The supplied GUID value should be used in the service which implements the IGetBook interface
• The book record which matches against the supplied Id is returned to the Get method
  • If no matching record is found, the Get method returns a 404
  • If a matching record is found, the Get method returns a 200 with the book in the body

Considerations

The SwaggerResponse attributes on the Get API endpoint may need to be updated. This will allow Swagger to provide documentation on the request and response types.

The FlatFilebookService may need to be replaced with one which contains a private collection of Book records, with the GetBook method returning only the matching record.

Remember that we haven't decided on a data storage technology or technique yet. So we don't need to implement a data repository.

Requirements

• The Get API endpoint should return a Book record which matches a supplied ID
• If the request to the Get API endpoint does not contain a valid GUID, a 403 is returned
• No data storage technology is included
• Unit and integration tests should be included
