一个超级简单的用例 - 使用redis队列放置图像下载作业

当我运行# main.py
from redis import Redis
from rq import Queue
from tasks import download_asset
queue = Queue(connection=Redis())
if __name__ == '__main__':
image_urls = ['https://image.com/image1.png', 'https://image.com/image2.png']
job1 = queue.enqueue(download_asset, image_urls[0], result_ttl=5000)
print job1
job2 = queue.enqueue(download_asset, image_urls[1], result_ttl=5000)
print job2
import time; time.sleep(3)
print job1.result
print job2.result
时，
python main.py结果没有，但我确实看到第二张图片已下载到文件夹中。 并在工人日志中
<Job 8de87fc3-0480-4181-bb57-182773eaa4dd: tasks.download_asset('https://image.com/image1.png')>
