Python Flask token身份认证

首先安装依赖：

pip install flask-jwt-extended

然后在主应用中（项目入口文件）加入以下代码：

from flask import Flask
from flask_jwt_extended import JWTManager #引入依赖
app = Flask(__name__)
app.config['JWT_SECRET_KEY'] = 'focusInYou' #jwt密钥 可自定义
jwt = JWTManager(app) #实例化

 user接口

from flask import Blueprint,request, session
from flask_jwt_extended import create_access_token, jwt_required ,get_jwt_identity #引入依赖
user_bp = Blueprint('user', __name__, url_prefix='/user') #注册蓝图
@user_bp.route('/login', methods=['POST'])
def user_login():reqJSONData = request.get_json(silent=True) #获取参数if not reqJSONData: return r(code=401, msg='注册失败, 请求参数为空')username = reqJSONData.get('username')password = reqJSONData.get('password')if not all([username, password]):return r(code=401, msg='登录, 缺少请求参数')#user = 去你的数据库里查出对应账号密码的用户信息赋值给user# 4. 用户不存在, 直接返回if not user:return r(code=404, msg='用户名或密码错误')else:access_token = create_access_token(identity=user[0]) #创建tokensession['user_info'] = userreturn r(msg='登录成功', data={"token":access_token})
@user_bp.route('/info', methods=['get'])
@jwt_required() #修饰器，表示请求接口需要在请求头内加入 Authorization: Bearer xxxx
def user_info():userInfo = get_jwt_identity()return r(msg='',data=userInfo)
