Support creating file schema for file response #447
Description
We support creating file fields via the apiflask.schemas.File field class, and use the metadata to set the type and the format:
class ImageIn(Schema):
image = File()But we still need to support creating the schema for file response. In that case, the whole response is a file, there isn't a key for the file. For example:
paths:
/report:
get:
summary: Returns the report in the PDF format
responses:
'200':
description: A PDF file
content:
application/pdf:
schema:
type: string
format: binaryI will create a FileSchema class that accepts type and format as arguments, then create the file schema from it. Example usage:
from apiflask.schemas import FileSchema
@app.get('/files/<filename>')
@app.output(FileSchema(type='string', format='binary'), content_type='image/png', description='An image file')
def get_file(filename):
return ...
