import json
import uvicorn
from bareasgi import (
Application,
text_reader,
text_writer
)
from bareasgi_cors import CORSMiddleware
async def get_info(scope, info, matches, content):
text = json.dumps(info)
return 200, [(b'content-type', b'application/json')], text_writer(text)
async def set_info(scope, info, matches, content):
text = await text_reader(content)
data = json.loads(text)
info.update(data)
return 204, None, None
# Create the CORS middleware class
cors_middleware = CORSMiddleware()
# Use the CORS middleware as the first middleware.
app = Application(info={'name': 'Michael Caine'}, middlewares=[cors_middleware])
app.http_router.add({'GET'}, '/info', get_info)
app.http_router.add({'POST', 'OPTIONS'}, '/info', set_info)
uvicorn.run(app, port=9010)
The POST method
In the above example an OPTION method is included with the POST. This is always required with a POST as a browser will try first with an OPTION.
