Flask 实现HTTP令牌token认证HTTPTokenAuth

由 假如想象 提交于 2020-08-10 08:26:05
Token认证 在restful设计中，用户认证模式通常使用json web token，而不会使用传统的HTTP Basic认证（传入账号密码） token认证模式如下：在请求header中加入token Flask中的实现 flask扩展flask-httpauth提供了该认证方法 $ pip install flask-httpauth 首先实例化 auth = HTTPTokenAuth(scheme='JWT') 校验token的方法（token_auth.py） from flask_httpauth import HTTPTokenAuth from itsdangerous import TimedJSONWebSignatureSerializer as Serializer, BadSignature, SignatureExpired from config import Config from home.libs.error_code import AuthFailed auth = HTTPTokenAuth(scheme='JWT') @auth.verify_token def verify_token(token): # Config.SECRET_KEY:内部的私钥，这里写在配置信息里 s = Serializer(Config.SECRET

How can I generate an unique url for a specific user

问题 I’m using flask to build a web app and I store data in a table called Orders. I want buyers to have access to a template that will display their order data, like tracking, status, etc. Also I want to give them some actions like the ability to return the order. For convenience and user experience purposes, I don’t want buyers to register. I want to email them a link that will directly give them access to their order information. So I will create a dynamic route for each order with a token. I

SocketIO + Flask Detect Disconnect

由 时光毁灭记忆、已成空白 提交于 2020-08-10 00:44:17
问题 I had a different question here, but realized it simplifies to this: How do you detect when a client disconnects (closes their page or clicks a link) from a page (in other words, the socket connection closes)? I want to make a chat app with an updating user list, and I’m using Flask on Python. When the user connects, the browser sends a socket.emit() with an event and username passed in order to tell the server a new user exists, after which the server will message all clients with socket
