Flask开发的流程之初体验

from flask import Flask

    SESSION_TYPE = "redis" # 指定 session 保存到 redis 中

    SESSION_USE_SIGNER = True # 让 cookie 中的 session_id 被加密签名处理

    PERMANENT_SESSION_LIFETIME = 86400 # session 的有效期，单位是秒

app.config.from_object(MyConfig)

# 开启csrf保护

CSRFProtect(app)

# 用于数据库迁移

Migrate(app, db)

manager.add_command('db',MigrateCommand)

# 配置redis

redis_store = redis.StrictRedis(host=MyConfig.REDIS_HOST, port=MyConfig.REDIS_PORT)

# 配置Session

Session(app)

if __name__ == '__main__':

    # app.run()

    manager.run()
