怎麼直接透過 API 進行續費查詢和續費管理

這篇文章帶給大家的內容是關於怎麼直接透過 API 進行續費查詢和續費管理，有一定的參考價值，有需要的朋友可以參考一下，希望對你有所幫助。

ECS 實例續費

本文主要涉及以下關鍵功能：

依照過期時間查詢雲端伺服器

續費實例

查詢雲端伺服器自動續費時間

設定雲端伺服器自動續費時間

對於包年包月的雲端伺服器，生命週期非常重要。如果雲端伺服器資源無法按時續費，將可能導致伺服器被鎖定甚至被釋放，從而影響業務持續性。 API 可協助您隨時了解並檢查資源的到期時間，並完成續費儲值功能。

本篇需關注以下API：

#查詢實例清單

#續費實例

查詢指定範圍內到期的雲端伺服器

查詢實例清單的API，透過篩選參數，您可以查詢在一定時間範圍內到期的實例資訊。透過設定過濾參數 ExpiredStartTime 和 ExpiredEndTime（時間參數 依照 ISO8601 標準表示，並需要使用 UTC 時間。格式為：yyyy-MM-ddTHH:mmZ。） ，可以方便地查詢該時間範圍內到期的實例清單。如果需要透過安全性群組進行過濾，只需加上安全性群組 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)

續費雲端伺服器

續費實例只支援包年包月的伺服器類型，不支援按量付費的伺服器，同時要求用戶必須支援帳號的餘額支付或信用支付。執行 API 的時候將執行同步的扣費和訂單產生。因此，執行 API 的時候必須確保您的帳號有足夠的資金支持自動扣費。

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)

續費實例將會自動完成扣費。完成續約後，您可以根據InstanceId查詢實例的資源到期時間。由於 API 為非同步任務，查詢資源到期時間可能需要延遲 10 秒才會變更。

開啟雲端伺服器自動續費

為了減少您的資源到期維護成本，針對包年包月的ECS 實例，阿里雲還推出了自動續費功能。自動續費扣款日為伺服器到期前第 9 天的 08:00:00。若前一日執行自動扣費失敗，將會繼續下一日定時執行，直到完成扣費或 9 天後到期資源鎖定。您只需要確保自己的帳號餘額或信用額度充足即可。

查詢自動續費設定

您可以透過 OpenAPI 來查詢並設定自動續費。此 API 僅支援包年包月的實例，按量付費的執行個體執行將會報錯。查詢實例的自動續費狀態支援一次最多查詢 100 個包年包月的實例，多個實例 ID 以逗號連線。

DescribeInstanceAutoRenewAttribut 的入參為實例 ID.

InstanceId：支援最多查詢 100 個包年包月的實例，多個實例 ID 以逗號連接。

python # check the instances is renew or not def describe_auto_renew(instance_ids, expected_auto_renew=True): describe_request = DescribeInstanceAutoRenewAttributeRequest() descbe_request = DescribeInstanceAutoRenewAttributeRequest() desbe_request().re_stail_stail_re_m)d quest=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。 = item.get ('InstanceId') ',' describe_auto_renew('i-1111,i-2222')

回傳內容如下：

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

如果設定自動續費，則傳回的屬性AutoRenewEnabled為true，否則回傳false。

設定和取消雲端伺服器的自動續費

#設定自動續費有三個入參：

InstanceId： 支援最多查詢100個包年包月的實例，多個實例ID 以逗號連接。

Duration：支援 1、2、3、6、12，單位為月。

AutoRenew：true/false， true為開啟自動續費，false為取消自動續費。

python 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:

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

续费成功后，您可以再执行一次查询。如果续费成功将返回续费时长以及是否开启自动续费。

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