我试图通过使用get_spot_price_history()函数的python中的boto获取当前的现货价格.
conn = boto.connect_ec2(aws_key, aws_secret)
prices = conn.get_spot_price_history("m3.medium", '2017-04-20T21:14:45.000Z', '2017-04-20T21:20:45.000Z',"us-east-1")
它给出了一个错误
Traceback (most recent call last):
File "run.py", line 22, in <module>
prices = conn.get_spot_price_history("m3.medium", '2017-04-20T21:14:45.000Z', '2017-04-20T21:20:45.000Z',"us-east-1")
