Flask实现JWT简单验证

使用koa和PHP springboot开发的都知道中间件实现验证，flask是通过python的装饰器实现。

下面记录实现过程和遇到的方法处理：

1. 安装插件flask_jwt_extended

pipenv install flask_jwt_extended

 

2.懒加载实现

 jwt=JWTManager()

def create_app():

....

jwt.init_app(app)

2.1 配置文件

JWT_SECRET_KEY='me1UMiUFhSUjqxSs'

JWT_ACCESS_TOKEN_EXPIRES=3600 #过期时间1小时

3. 生成token  POST http://localhost:5000/api/v1/login

@web.route('/login',methods=['POST'])
def login():
    user=request.get_json()
    # password=request.json.get('password')
    token=create_access_token(identity=user)

    return token,200

>>>返回示例：

3.1 请求示例

 

POST http://{{host}}/api/v1/login
Content-Type: application/json


{
    "name":"Bob",
    "password":"123456"
}

3.2 JWT验证

@web.route('/hash')
@jwt_required(optional=False)
def hash():
    return generate_password_hash('123456'),200

注意如果不加optional=False会出现错误

TypeError: wrapper() missing 1 required positional argument: 'fn'

3.3 请求示例

### /api/v1/hash 密码加密实现
