flask-login: Chrome ignoring cookie expiration?

由 ⅰ亾dé卋堺 提交于 2020-12-27 08:15:38
问题 I've got the authentication working with flask-login, but it seems like no matter what I use for the cookie duration in flask, the session is still authenticated. Am I setting the config variables properly for flask-login? I've tried app.REMEMBER_COOKIE_DURATION = datetime.timedelta(seconds=30) app.config["REMEMBER_COOKIE_DURATION"] = datetime.timedelta(seconds=30) Even if I close the browser, wait a while, and hit a url that should be protected, I can still access it. Is this related to this

JavaScript Blob to download a binary file creating corrupted files

由 被刻印的时光 ゝ 提交于 2020-12-27 06:20:10
问题 I have a binary file (python pickle file, to be exact). Whenever such a file is requested, I create one on server side, and then send it to the client via flask's send_file as an AJAX request. Next, I need to download this file automatically to the client side, so I have used this answer. The problem is that, the created file on the server normally has a size 300 Bytes, and the file downloaded on the client side is of the size >500 Bytes. Plus whenever I try to reuse the pickle file, it doesn

Displaying JSON in the HTML using flask and local JSON file

由 时光怂恿深爱的人放手 提交于 2020-12-26 12:22:08
问题 I work with the Python flask, HTML, and local JSON file to display the JSON data from a local JSON file in the HTML. Once the flask reads a local JSON file, it is sent to index.html with jsonify. After then, using that data I want to display the information. I can the JSON data in the flask side, but have struggled with displaying it in the HTML. Could you let me know what I missed? flask code import os from flask import Flask, render_template, abort, url_for, json, jsonify import json import

During a long-running process, will Flask be insensitive to new requests?

由 喜夏-厌秋 提交于 2020-12-26 08:40:06
问题 My Flask project takes in orders as POST requests from multiple online stores, saves those orders to a database, and forwards the purchase information to a service which delivers the product. Sometimes, the product is not set up in the final service and the request sits in my service's database in an "unresolved" state. When the product is set up in the final service, I want to kick off a long-running (maybe a minute) process to send all "unresolved" orders to the final service. During this

How to return plain text from flask endpoint? Needed by Prometheus

由 穿精又带淫゛_ 提交于 2020-12-26 08:04:50
问题 I need to setup a /metrics endpoint so that Prometheus can consume statistics about an endpoint. How do I go about doing this? I have this in my Flask app: @app.route('/metrics') def metrics(): def generateMetrics(): metrics = "" ... some string builder logic return metrics response = make_response(generateMetrics(), 200) response.mimetype = "text/plain" return response Is this the best way? What is the difference between returning a String (just returning metrics here) and returning plain
