如何在Flask-Security中设置配置？

from flask import Flask
from flask_security import Security, SQLAlchemyUserDatastore

app = Flask(__name__)

app.config['SQLALCHEMY_DATABASE_URI'] = '数据库连接字符串'
app.config['SECRET_KEY'] = '密钥'
# 其他配置项...

from flask_sqlalchemy import SQLAlchemy

db = SQLAlchemy(app)

class User(db.Model):
    # 用户模型定义

class Role(db.Model):
    # 角色模型定义

# 创建用户数据存储对象
user_datastore = SQLAlchemyUserDatastore(db, User, Role)

security = Security(app, user_datastore)

app.config['SECURITY_REGISTERABLE'] = True  # 允许用户注册
app.config['SECURITY_PASSWORD_HASH'] = 'bcrypt'  # 密码哈希算法
app.config['SECURITY_PASSWORD_SALT'] = 'salt'  # 密码哈希盐值
# 其他配置项...

if __name__ == '__main__':
    app.run()
