问题 Hello I'm trying to setup flask-socketio in a docker container. It seems to run but I get an error( from the browser) when I try to access localhost on port 5000 like I'm used to do with flask apps. It say's: unable to connect! I will show you the 5 important files: Dockerfile, requirements.txt, docker-compose.yml, web_app.py and index.html Dockerfile: FROM python:3.6.5 WORKDIR /code COPY * /code/ RUN pip install -r requirements.txt requirements.txt: Flask==1.0.2 Flask-SocketIO==3.0.1

Flask-RESTful: Using GET to download a file with REST

由 故事扮演 提交于 2021-02-07 19:14:13
问题 I am trying to write a file sharing application that exposes a REST interface. The library I am using, Flask-RESTful only supports returning JSON by default. Obviously attempting to serve binary data over JSON is not a good idea at all. What is the most "RESTful" way of serving up binary data through a GET method? It appears possible to extend Flask-RESTful to support returning different data representations besides JSON but the documentation is scarce and I'm not sure if it's even the best

由 余生颓废 提交于 2021-02-07 14:43:08
问题 I am new to python and still learning. I created a small python 3.6 Flask webapp on pythonanwhere and found out that send_file() is not working on pythonanywhere servers.

Importing from main app in a flask blueprint

由 只愿长相守 提交于 2021-02-07 14:20:02
问题 I'm writing an application with one blueprint. My application uses Flask-SQLAlchemy, so my blueprint needs access to the main app's db object (created by Flask-SQLAlchemy) in order to create its own models. However, when I try to get the db object with current_app.db , flask gives me the following error: RuntimeError: working outside of application context Here is my main __init__.py : from flask import Flask from app.uploader import uploader app = Flask(__name__) from flask.ext.sqlalchemy
