【第85课】怎样使用API查询资源价格/怎样使用API查询资源的可用配额

查询资源价格

使用查询按需产品价格和查询包年/包月产品价格，根据云服务类型、资源类型、云服务区和资源规格四个条件来查询产品价格。

例如查询华东上海二可用区、通用计算型、Linux操作系统、s6.small.1规格的包月，一个月的价格。

POST https://bss.myhuaweicloud.com/v2/bills/ratings/period-resources/subscribe-rate

{
	"product_infos": [

		{
			   "id": "1",
			"cloud_service_type": "hws.service.type.ec2",
			"resource_type": "hws.resource.type.vm",
			"resource_spec": "s6.small.1.linux",
			"region": "cn-east-2",
			"available_zone": "cn-east-2a",
			"period_type": 2,
			"period_num": 1,
			"subscription_num": 1
		}
	],
	"project_id": "05041fea8a8025662f4ac00927982f3e"
}

响应信息如下所示，其中official_website_amount字段的取值即为包年/包月产品价格。

{
	-"official_website_rating_result": {
		"official_website_amount": 32.2,
		"measure_id": 1,
		-"product_rating_results": [-{
			"id": "1",
			"product_id": "00301-233164-0--0",
			"official_website_amount": 32.2,
			"measure_id": 1
		}]
	},
	"optional_discount_rating_results": [],
	"currency": "CNY"
}

查询资源的可用配额

如需查询当前账号的资源配额信息，包括已使用的配额，可以通过调用查询租户配额接口。

GET https://ecs.cn-east-2.myhuaweicloud.com/v1/05041fea8a8025662f4ac00927982f3e/cloudservers/limits

响应信息如下，例如通过maxTotalInstances可以查看云服务器的最大申请数量，通过totalInstancesUsed可以查看当前云服务器使用个数。

{
	-"absolute": {
		"maxServerMeta": 128,
		"maxPersonality": 5,
		"maxImageMeta": 128,
		"maxPersonalitySize": 10240,
		"maxSecurityGroupRules": 20,
		"maxTotalKeypairs": 1000,
		"totalRAMUsed": 22528,
		"totalInstancesUsed": 4,
		"maxSecurityGroups": 10,
		"totalFloatingIpsUsed": 0,
		"maxTotalCores": 8000,
		"totalSecurityGroupsUsed": 1,
		"maxTotalFloatingIps": 10,
		"maxTotalInstances": 1000,
		"totalCoresUsed": 11,
		"maxTotalRAMSize": 16384000,
		"maxServerGroups": 32,
		"maxServerGroupMembers": 16,
		"totalServerGroupsUsed": 0,
		"maxTotalSpotInstances": 20,
		"maxTotalSpotCores": 320,
		"maxTotalSpotRAMSize": 655360,
		"totalSpotInstancesUsed": 0,
		"totalSpotCoresUsed": 0,
		"totalSpotRAMUsed": 0,
		"maxFaultDomainMembers": 200,
		"limit_by_flavor": []
	}
