JSON Schema request payload support & payload automation

[zhiguang-chen]

When a request body is defined by a JSON Schema, we should be able to auto-generate payloads based on that schema.

Goals:

• When the request body is a schema (OpenAPI/JSON Schema):

  • Automatically generate a valid payload.
  • In the UI, provide controls to generate invalid payloads (e.g. missing required fields, wrong types, edge cases).

• Allow requestMiddleware to plug in custom payload generators, so advanced users can fully control how payloads are created.

• Design a way to manage and reuse schemas across the workspace:

  • Shared schema files (for models used by multiple requests).
  • Clean references from requests/collections to these schema definitions.

Notes:

• API docs will support OpenAPI/JSON Schema, so the schema storage and reuse model should work for:

  • API documentation
  • Request payload generation
  • Future test automation.
