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：


pip install flask-dapr


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)
