Swagger send body and formData parameter [duplicate]

Answer 1

According to the swagger specifications see, type:body and type:formData cannot exist together for the same operation.

Answer 2

One way to resolve the problem is to set "datas" as form parameter with the type "file". Here is an example:

  parameters:
    - name: petId
      in: path
      description: ID of pet to update
      required: true
      type: integer
      format: int64
    - name: additionalMetadata
      in: formData
      description: Additional data to pass to server
      required: false
      type: string
    - name: file
      in: formData
      description: file to upload
      required: false
      type: file

UPDATE: body parameters and form parameters cannot co-exist: https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#parameterObject

Body - The payload that's appended to the HTTP request. Since there can only be one payload, there can only be one body parameter. The name of the body parameter has no effect on the parameter itself and is used for documentation purposes only. Since Form parameters are also in the payload, body and form parameters cannot exist together for the same operation.
