Dapr Python SDK 与 Flask 集成

如何创建基于 Python FastAPI 的 Dapr 虚拟 actor

Dapr Python SDK 使用 flask-dapr 扩展与 Flask 进行集成。

安装

你可以通过下面的方式下载和安装 Dapr Flask 扩展模块：

• Stable
• Development

pip install flask-dapr

Note

The development package will contain features and behavior that will be compatible with the pre-release version of the Dapr runtime. 在安装 <code>dapr-dev</code> 包之前，请务必卸载任何稳定版本的 Python SDK 扩展。

pip install flask-dapr-dev

如何使用Dapr扩展来开发和运行Dapr应用程序

from flask import Flask
from flask_dapr.actor import DaprActor
from dapr.conf import settings
from demo_actor import DemoActor
app = Flask(f'{DemoActor.__name__}Service')
# Enable DaprActor Flask extension
actor = DaprActor(app)
# Register DemoActor
actor.register_actor(DemoActor)
# Setup method route
@app.route('/GetMyData', methods=['GET'])
def get_my_data():
    return {'message': 'myData'}, 200
# Run application
if __name__ == '__main__':
    app.run(port=settings.HTTP_APP_PORT)
