Stephane Carrez a8bc3360fd Fix 3522: [BUG][Ada] Wrong style for generated Ada model types and missing security scopes (#4863)
* [Ada] Operation security scopes are ignored when generating the server (#1043)
- Update fromOperation() to keep the operation required scopes for each auth
  method and store that information in the x-scopes vendor extensions attribute
- Update postProcessOperationsWithModels() to process the operation required
  scopes and build a list of authMethods which only contain the required scopes
  for the operation and store these authMethods in the x-auth-scopes attribute.
- Update postProcessAuthMethod() to handle the logic of filtering and building
  the operation authMethod (new instances are created because we must not
  modify the global authMethod definitions)
- Update the Ada server templates to use the x-auth-scopes instead of authMethods
  Add a URL prefix parameter for the Ada server instantiation

* Fix Ada code generator
- update to generate Ada style type names (broken by the use of Camelize)
- update the templates for Ada Util and Swagger libraries

* Update generated GNAT project to add the 'utilada_xml' dependency

* Update the Ada samples

* Fix compilation of the petstore Ada sample

Swagger Petstore Ada Client

Overview

This Ada client uses the Petstore API to demonstrate how to use the generator and use the generated Ada code. The following files are generated by Swagger Codegen:

  • src/client/samples-petstore-models.ads
  • src/client/samples-petstore-models.adb
  • src/client/samples-petstore-clients.ads
  • src/client/samples-petstore-clients.adb

The 'Models' package contains the definition of types used by the request or response in the API operations. It also provides operations to serialize and deserialize these objects in JSON, XML or form-based data streams.

The 'Clients' package contains the definition of operations provided by the Petstore API.

Requirements.

To build this sample, you must have installed the GNAT Ada compiler as well the following libraries:

Building the petstore client

Build the petstore client by using the following command:

gprbuild -Ppetstore -p

Using the Swagger Ada code

Initialization

The HTTP/REST support is provided by Ada Util and encapsulated by Swagger Ada. If you want to use Curl, you should initialize with the following:

   Util.Http.Clients.Curl.Register;

But if you want to use AWS, you will initialize with:

   Util.Http.Clients.Web.Register;

After the initialization is done, you will declare a client instance to access the API operations:

   C : Samples.Petstore.Clients.Client_Type;

The 'Client_Type' is the generated type that will implement the operations described in the OpenAPI description file.

And you should initialize the server base URI you want to connect to:

  C.Set_Server ("http://petstore.swagger.io/v2");

At this stage, you can use the generated operation.

Calling an operation

Let's retrieve some pet information by calling the 'Get_Pet_By_Id' operation. This operation needs an integer as input parameter and returns a 'Pet_Type' object that contains all the pet information. You will first declare the pet instance as follows:

  Pet  : Samples.Petstore.Models.Pet_Type;

And then call the 'Get_Pet_By_Id' operation:

  C.Get_Pet_By_Id (768, Pet);

At this stage, you can access information from the 'Pet' instance:

  Ada.Text_IO.Put_Line ("Id      : " & Swagger.Long'Image (Pet.Id));
  Ada.Text_IO.Put_Line ("Name    : " & Swagger.To_String (Pet.Name));
  Ada.Text_IO.Put_Line ("Status  : " & Swagger.To_String (Pet.Status));
