使用OpenApi完成云服务器ECS续费管理

2022-02-24 19:51:14

在除了可以在ECS控制台或者售卖页进行云服务器续费之外，阿里云还可以直接通过API来续费查询和续费管理。

本文将涉及到几个关键功能

按照过期时间查询云服务器
续费实例
查询云服务器自动续费时间
设置云服务器自动续费时间

对于包年包月的云服务器的生命周期是非常重要的，如果云服务器资源不能按时的续费将可能导致服务器被锁定甚至释放影响您的业务持续性。所以我们需要API方便的知道和检查资源的到期时间。同时可以方便的完成续费充值。

本篇您需要关注几个API

查询指定范围内到期的云服务器

通过查询实例列表的API通过下面的过滤参数您可以查询在一定时间范围内到期的实例信息。通过设置过滤参数的ExpiredStartTime和ExpiredEndTime，时间参数为按照 ISO8601 标准表示，并需要使用 UTC 时间。格式为：yyyy-MM-ddTHH:mmZ。

就可以方便的查询在这个时间内到期的实例列表。如果需要通过安全组来进行过滤只需要加上安全组id即可。

INSTANCE_EXPIRED_START_TIME_IN_UTC_STRING = '2017-01-22T00:00Z'
INSTANCE_EXPIRE_END_TIME_IN_UTC_STRING = '2017-01-28T00:00Z'

def describe_need_renew_instance(page_size=100, page_number=1, instance_id=None,
                                 check_need_renew=True, security_group_id=None):
    request = DescribeInstancesRequest()
    if check_need_renew is True:
        request.set_Filter3Key("ExpiredStartTime")
        request.set_Filter3Value(INSTANCE_EXPIRED_START_TIME_IN_UTC_STRING)
        request.set_Filter4Key("ExpiredEndTime")
        request.set_Filter4Value(INSTANCE_EXPIRE_END_TIME_IN_UTC_STRING)
    if instance_id is not None:
        request.set_InstanceIds(json.dumps([instance_id]))
    if security_group_id:
        request.set_SecurityGroupId(security_group_id)
    request.set_PageNumber(page_number)
    request.set_PageSize(page_size)
    return _send_request(request)

续费云服务器

续费实例只支持包年包月的服务器类型，不支持按量付费的服务器，同时要求用户必须支持账号的余额支付或信用支付。在执行API的时候将执行同步的扣费和订单生成。所以在执行API的时候必须保证您的账号有足够的资金支持自动扣费。


def _renew_instance_action(instance_id, period='1'):
    request = RenewInstanceRequest()
    request.set_Period(period)
    request.set_InstanceId(instance_id)
    response = _send_request(request)
    logging.info('renew %s ready, output is %s ', instance_id, response)

续费实例将会自动完成扣费，在续费执行之后您可以根据InstanceId进行查询实例的资源到期时间。由于API为异步任务，查询资源到期时间可能需要延迟10秒才会变化。

开启云服务器自动续费

为了减少您的资源到期维护成本，针对包年包月的 ECS 实例，阿里云还推出了自动续费功能, 自动续费扣款日为服务器到期前第 7 天的 08:00:00，如果前一日执行自动扣费失败，将会继续下一日定时继续执行，直到扣费成或者7天之后到期资源锁定。您只需要保证自己的账号的余额或者信用额度充足即可。

查询自动续费设置

我们也提供了OpenApi来查询和设置自动续费，该API也仅支持包年包月的实例，按量付费的实例执行将会报错。
查询实例的自动续费状态支持一次最多查询100个包年包月的实例，多个实例id以逗号连接。

DescribeInstanceAutoRenewAttribut的入参为实例Id

InstanceId：支持最多查询100个包年包月的实例，多个实例id以逗号连接。

# check the instances is renew or not
def describe_auto_renew(instance_ids, expected_auto_renew=True):
    describe_request = DescribeInstanceAutoRenewAttributeRequest()
    describe_request.set_InstanceId(instance_ids)
    response_detail = _send_request(request=describe_request)
    failed_instance_ids = ''
    if response_detail is not None:
        attributes = response_detail.get('InstanceRenewAttributes').get('InstanceRenewAttribute')
        if attributes:
            for item in attributes:
                auto_renew_status = item.get('AutoRenewEnabled')
                if auto_renew_status != expected_auto_renew:
                    failed_instance_ids += item.get('InstanceId') + ','                                        

describe_auto_renew('i-1111,i-2222')

返回的内容如下

{"InstanceRenewAttributes":{"InstanceRenewAttribute":[{"Duration":0,"InstanceId":"i-1111","AutoRenewEnabled":false},{"Duration":0,"InstanceId":"i-2222","AutoRenewEnabled":false}]},"RequestId":"71FBB7A5-C793-4A0D-B17E-D6B426EA746A"}

如果设置自动续费则返回的属性AutoRenewEnabled则为true，否则返回false。

设置和取消云服务器的自动续费

设置自动续费有三个入参：

InstanceId：支持最多查询100个包年包月的实例，多个实例id以逗号连接。
Duration：支持 1，2，3，6，12，单位为月
AutoRenew：true/false， true为开启自动续费，false为取消自动续费

def setting_instance_auto_renew(instance_ids, auto_renew = True):
    logging.info('execute enable auto renew ' + instance_ids)
    request = ModifyInstanceAutoRenewAttributeRequest();
    request.set_Duration(1);
    request.set_AutoRenew(auto_renew);
    request.set_InstanceId(instance_ids)
    _send_request(request)

执行成功返回Response如下:

{"RequestId":"7DAC9984-AAB4-43EF-8FC7-7D74C57BE46D"}

续费成功后您可以再执行一次查询即可, 如果续费成功会返回续费的时长和是否开启自动续费。

{"InstanceRenewAttributes":{"InstanceRenewAttribute":[{"Duration":1,"InstanceId":"i-1111","AutoRenewEnabled":true},{"Duration":1,"InstanceId":"i-2222","AutoRenewEnabled":true}]},"RequestId":"7F4D14B0-D0D2-48C7-B310-B1DF713D4331"}
