File Upload: Allow to set values like contentType in RequestBuilder.body or options.reportProgress in RequestBuilder.build

[ophirKatz]

Hi! I'm trying to implement file upload in my application, using the Blob type. Specifically, I have a request body object that contains some normal fields and one File field:

interface FileUploadRequest {
  name: string;
  file: File;
}

I want to use the generated http service in order to send this request, but I need to use FormData to send the file. The RequestBuilder supports Blob types and can create a FormData object with all fields, but only via the rb.body method. But, the service does not expose a parameter to override the body's content type (which controls whether FormData is used or not - 'multipart/form-data'), and the default is 'application/json'. Moreover, I'd like to override the value for reportProgress in the options object passed to rb.build, but again - not possible.

Any ideas is this is possible? Or how it can be done using the generated code?

Thank you!

Can you post the OpenAPI descriptor for the operation? Seems like you're not mapping the content type in the requestBody element
