ZStack - 创建区域、集群

/ 前言 /

在ZStack的API中, 大多数的API返回的是一个任务结果查询地址, 此时我们就需要根据这个地址轮训去查询任务状态及结果

{ 
	"location": "http://localhost:8080/v1/api-jobs/967a26b7431c49c0b1d50d709ef1aef3" 
}

创建区域

API名称

创建区域(CreateZone)
请求方式

POST zstack/v1/zones

curl示例

curl -H "Content-Type: application/json" \
-H "Authorization: OAuth b86c9016b4f24953a9edefb53ca0678c" \
-X POST -d '{"params":{"name":"TestZone","description":"test zone"}}' \ 		
http://localhost:8080/zstack/v1/zones

返回示例

{"inventory": {
	"uuid": "0d26522305c34d07b5661ccda62053c0", "name": "TestZone",
	"description": "Test",
	"state": "Enabled",
	"type": "zstack",
	"createDate": "Jun 7, 2017 9:20:28 PM", "lastOpDate": "Jun 7, 2017 9:20:28 PM"
}}

创建集群

API名称

创建一个集群(CreateCluster)
请求方式

POST zstack/v1/clusters

curl示例

curl -H "Content-Type: application/json" \
-H "Authorization: OAuth b86c9016b4f24953a9edefb53ca0678c" \
-X POST -d '{"params":{"zoneUuid":"e1fb7d87073b397c857eaeeb16243103","name":"cluster1 ","description":"test","hypervisorType":"KVM"}}' \
http://localhost:8080/zstack/v1/clusters

返回示例

{"inventory": {
	"name": "cluster1",
	"uuid": "dc7442bb39674d779d688369329ba845", 
	"description": "test",
	"state": "Enabled",
	"hypervisorType": "KVM",
	"createDate": "Jun 7, 2017 9:20:31 PM",
	"lastOpDate": "Jun 7, 2017 9:20:31 PM",
	"zoneUuid": "342b68c14869412984d6327a58b18f9b", 
	"type": "zstack"
}}

ZStack中, 大多数的API在调用后返回的是

user_name = 'admin'
user_password='password'
host = 'http://localhost:8080/'

# 登录
def login():
	# 登录API需要对密码进行SHA-512算法加密
    sha512 = hashlib.sha512()
    sha512.update(user_password)
    password = sha512.hexdigest()
    content = {
        "logInByAccount": {
            "password": password,
            "accountName": user_name}

    data = json.dumps(content)
    url = host + 'zstack/v1/accounts/login'
    headers = {"Content-Type": "application/json"}
    response = requests.put(url, data, headers=headers)
