gunicorn

问题 Following the tutorial here I have the following 2 files: app.py from flask import Flask, request app = Flask(__name__) @app.route('/', methods=['GET']) def hello(): """Return a friendly HTTP greeting.""" who = request.args.get('who', 'World') return f'Hello {who}!\n' if __name__ == '__main__': # Used when running locally only. When deploying to Cloud Run, # a webserver process such as Gunicorn will serve the app. app.run(host='localhost', port=8080, debug=True) Dockerfile # Use an official

问题 tl;dr A method decorated with route can't handle concurrent requests while Flask is served behind a gunicorn started with multiple workers and threads, while two different methods handle concurrent requests fine. Why is this the case, and how can the same route be served concurrently?

问题 I'm trying to use the gaiohttp worker in Gunicorn with a Django app I'm developing with the following command: gunicorn -k gaiohttp -b localhost:8080 myproject.wsgi My ultimate goal is to be able to process requests concurrently - i.e. have 1 gunicorn worker process multiple requests concurrently. There are I/O bound operations which makes these requests slow. I know an event loop is already running when I'm processing a request: class MyView(View): def get(self, request): loop = asyncio.get

问题 I'm running Flask Restful on a server in production mode using Python 3.6 and hitting an endpoint that requires jwt auth, but I keep getting a "NoAuthorizationError Missing Authorization Header" error. The strange part is that the very same request is sent using Postman to the local version of the exact same Flask app on my mac and it works just fine without any errors.
