Send asynchronous requests

Method

Use the async def keyword to define an asynchronous method, and call await client.{Method name}_async() to invoke it.

import asyncio
import os

from alibabacloud_ecs20140526.models import DescribeImagesRequest
from alibabacloud_ecs20140526.client import Client
from alibabacloud_tea_openapi.models import Config

In this example, a request is sent to call the Elastic Compute Service (ECS) API.


async def main():
    config = Config(
        access_key_id=os.environ.get('ALIBABA_CLOUD_ACCESS_KEY_ID'),
        access_key_secret=os.environ.get('ALIBABA_CLOUD_ACCESS_KEY_SECRET'),
        endpoint='ecs-cn-hangzhou.aliyuncs.com'
    )
    client = Client(config)
    request = DescribeImagesRequest(
        region_id='cn-hangzhou'
    )

    response = await client.describe_images_async(request)
    print(response)
    return response


loop = asyncio.get_event_loop()
loop.run_until_complete(main())
