Open Api Spec for bearer Token

I can’t understand where and what i need to write for adding Bearer Token Auth for my API JSON SPEC.

I’ve added security schema in %OpenApiSpex.OpenApi{}

%OpenApi{
      servers: [%Server{url: url}],
      info: %Info{
        title: to_string(Application.spec(:getmsg_api, :description)),
        version: to_string(Application.spec(:getmsg_api, :vsn))
      },
      components: %Components{
        securitySchemes: %{"authorization" => %OpenApiSpex.SecurityScheme{
          type: "apiKey",
          name: "Autorization",
          in: "header"}
        }
      },
      # Populate the paths from a phoenix router
      paths: Paths.from_router(Router)
    }

I’ve added macro security to my Phoenix.Controller. But i don’t understand, what it does.

security [%{}, %{"api_key" => ["write:message", "read:message"]}]

This is one of method from this controller

operation :index,
    summary: "List messages",
    parameters: [
      token: [
        in: :header,
        name: "Authorization",
        schema: %OpenApiSpex.Schema{type: :string},
        required: true,
        example: "Bearer valid_token"
      ]],
    responses: %{
      200 => {"List of messages", "application/json", OpenApi.MessageListResponse},
      401 => {"Permission denied", "application/json", OpenApi.PermissionDeniedResponse}
    }

  def index(conn, _params) do
    messages = Msgs.list_all()
    render(conn, "index.json", messages: messages)
  end

I’m missing something, but don’t know what.

When i’m trying to test method /GET through swaggerui, there is no req_header 'autorization` with value “Bearer some_token_value”

curl from swaggerui

curl -X 'GET' \
  'http://localhost:4000/getmsg/api/messages' \
  -H 'accept: application/json' \
  -H 'x-csrf-token: TCwFJzMqJhoFKAQLClAYIV9ULgwEQD8taKJRWksmULaZ8iJE7akos9GG'

Solved!

Security scheme in OpenApi{} struct and in macro OpenApiSpex.ControllerSpecs.security/1 must have same key (in my case it is “bearerAuth”)! And i had spelling mistake in field name in my security scheme.

%OpenApi{
      servers: [%Server{url: url}],
      info: %Info{
        title: to_string(Application.spec(:getmsg_api, :description)),
        version: to_string(Application.spec(:getmsg_api, :vsn))
      },
      components: %Components{
        securitySchemes: %{"bearerAuth" => %OpenApiSpex.SecurityScheme{
          type: "apiKey",
          name: "Authorization",
          in: "header"}
        }
      },
      # Populate the paths from a phoenix router
      paths: Paths.from_router(Router)
    }

and in controller

security [%{"bearerAuth" => []}]

so correct curl generated

curl -X 'GET' \
  'http://localhost:4000/getmsg/api/messages' \
  -H 'accept: application/json' \
  -H 'Authorization: Bearer SFMyNTY.g2gDYQFuBgCHP8PphgFiAAFRgA.HAuxlwCHIsGcRibuYnWuDaLOcjx_ZB44RdcAwPPy3xA' \
  -H 'x-csrf-token: NmQ5ETMwXAAjLSk4ESQYL3E-e3gxdEYgU2siii6NEdvirtMHIG5IaG6T'
