Excerpt

If you want to use Open API 3.0 with HTTP/2 agents, you require an Open API profile configuration. You select the profile that you configure in the HTTP/2 Server agent configuration. In the Open API profile configuration, you import your OpenAPI specification file and view any other included files defined by the specification.

Info

  • All schemas that require a UDR must be named. Due to a limitation in the third party parsing library used by OpenAPI, unnamed schemas cannot be detected and will not generate a corresponding UDR. Therefore, you must name all schemas that require a UDR.

  • Field names in the yaml specification file containing the following symbols will be replaced with unique string of characters during the UDR generation process as shown below:

    • @ -> _40_

    • . -> _2E_

    • - -> _2D_

For example, the field "test-name" will be converted into "test_2D_name" as a UDR.

  • All tab indentations found in the Open API yaml files will be replaced with two spaces. 

Configuration

The OpenAPI profile consists of the following tabs:

Table of Contents
minLevel2
maxLevel2
outlinefalse
typelist

General Tab

Open API Profile Configuration - General tab

Setting

Description

ImportImport

Imports the OpenAPI Open API specification file from where the desktop client is running. Upon successful import, the contents of the file will be displayed in the box belowthe local file directory of the desktop or desktop client.

View

Opens the selected OPEN API schema file.

Note

Refreshing the content.

To refresh the content of the imported API file or the contents of other included files, the imported file will have to be imported once again.

Advanced Tab

Setting

Description

Ignore Read Only Tag

Select this option to ignore the readOnly tag in the schema file.

Info

Info!

When UDRs are generated from the OpenAPI specification file, some UDR fields found in the response body are marked as read-only. This prevents HTPP/2 Server from setting these fields in the APL to generate a proper response.

By selecting this option, it allows HTTP/2 Server agents to be able to set the readOnly fields in the APL for use cases that require a response from the HTTP/2 Server agent. 

Add “additionalProperties: false” to component schemas

Select this option to add the “additionalProperties: false” to each component in the schema file.

Limitations 

This section lists the limitations that users may encounter when using the OpenAPI profile.

OpenAPI specification schema which contains oneOf tag will be decoded as a map instead of a UDR

In the following example, the SubscriptionData schema contains the subscrCond property with oneOf tag:

Example: SubscriptionData schema contains the subscrCond with oneOf tag

Code Block
SubscriptionData:
      description: Information of a subscription to notifications to NRF events, included in subscription requests and responses
      type: object
      required:
        - nfStatusNotificationUri
        - subscriptionId
      properties:
        nfStatusNotificationUri:
          type: string
        reqNfInstanceId:
          $ref: 'TS29571_CommonData.yaml#/components/schemas/NfInstanceId'
        subscrCond:
          oneOf:
            - $ref: '#/components/schemas/NfInstanceIdCond'
            - $ref: '#/components/schemas/NfInstanceIdListCond'
            - $ref: '#/components/schemas/NfTypeCond'
            - $ref: '#/components/schemas/ServiceNameCond'
            - $ref: '#/components/schemas/AmfCond'
            - $ref: '#/components/schemas/GuamiListCond'
            - $ref: '#/components/schemas/NetworkSliceCond'
            - $ref: '#/components/schemas/NfGroupCond'
            - $ref: '#/components/schemas/NfSetCond'
            - $ref: '#/components/schemas/NfServiceSetCond'
            - $ref: '#/components/schemas/UpfCond'
            - $ref: '#/components/schemas/ScpDomainCond'
            - $ref: '#/components/schemas/NwdafCond'
            - $ref: '#/components/schemas/NefCond'

The subscrCond is a schema of NfSetCond but it is decoded as a map with key value pair as shown below:

Example: SubscriptionData schema decoded in the APL:

Code Block
[openapi.issue_http.OAPI_NrfMgt.udr.SubscriptionData]
  nfStatusNotificationUri: http://localhost/dummy
  subscriptionId: 123456
  subscrCond: {nfSetId=MU01}

To retrieve the value of the map, enter the following code in APL:

Code Block
string ID = mapGet((map<string, any>)subscriptionData.subscrCond, "nfSetId");
debug(ID);

The debug output is as follows:

Code Block
MU01
