身份验证示例

以下示例说明了如何在 BFC API 中创建身份验证会话。

Curl 示例：

%export BFC_HOST=10.10.x.x
%curl  -k https://$BFC_HOST:8443/BFC/1.0/login -X POST \
-d  "{\"username\":\"core/admin\",\"password\":\"changeme\"}" \
-H "Content-Type:application/json"
RESPONSE= <session token>  i.e. "d147eb4031217717c5af68edf33cd40c"%
%export BFC_SESSION= d147eb4031217717c5af68edf33cd40c

Python 示例：

from httplib import HTTPSConnection
import json
bfcHost = "10.10.x.x"
conn = HTTPSConnection(bfcHost + ':8443')
conn.connect()
conn.request(method='POST', url='/BFC/1.0/login', 
             body='{"username":"admin","password":"changeme"}', 
             headers={'Content-Type':'application/json'})
session = json.loads(conn.getresponse().read())
print session

网格列表示例

以下示例说明了如何检索一组网格的相关信息。

Curl 示例：

curl -k -v https://$BFC_HOST:8443/BFC/grids \
  -H "Content-Type:application/json" \
  -H "Authorization:$BFC_SESSION"

Python 示例：

session = get_session()
conn = HTTPSConnection(bfcHost + ':8443')
conn.connect()
conn.request(method='GET',
             url='/BFC/grids',
             headers={'Content-Type':'application/json',
                      'Authorization':session})
grids = json.loads(conn.getresponse().read())
打印网格

单个网格的详细信息

以下示例说明了如何检索单个网格的相关信息。

Curl 示例：

curl -k -v https://$BFC_HOST:8443/BFC/grids/$GRID_NAME \
  -H "Content-Type:application/json" \
  -H "Authorization:$BFC_SESSION"

Python 示例：

session = get_session()
gridName = 'productionApiTest'
conn = HTTPSConnection(bfcHost + ':8443')
conn.connect()
conn.request(method='GET',
             url='/BFC/grids/' + gridName,
             headers={'Content-Type':'application/json',
                      'Authorization':session})
grid = json.loads(conn.getresponse().read())
打印网格

网格创建示例

以下示例说明了如何在 BFC API 中创建网格。

Curl 示例：

curl -k -v -X POST "https://$BFC_HOST:8443/BFC/grids?numAppIPs=3" \
  -H "Content-Type:application/json" \
  -H "Authorization:$BFC_SESSION" \
  -d "{\"grid\":{\"name\":\"productionApiTest\",
                 \"xen_config\":{\"grid_server_configuration\":{\"min\":1,
                                                   \"target\":1,
                                                   \"max\":1,
                                                   \"selection_criteria\":[]}},
                 \"grid_controller_user\":\"cadev@ca.com\",
                 \"grid_controller_password\":\"myPass\",
                 \"description\":\"Xen grid for demo\"}}"

Python 示例：

session = get_session()
conn = HTTPSConnection(bfcHost + ':8443')
conn.connect()
conn.request(method='POST',
             url='/BFC/grids?numAppIPs=2',
             headers={'Content-Type':'application/json',
                      'Authorization':session},
             body = json.dumps({"grid":{"name":"productionApiTest",
                 "xen_config":{"grid_server_configuration":{
                        "min":1,
                        "target":1,
                        "max":2,
                        "selection_criteria":[]}},
                 "grid_controller_user":"cadev@ca.com",
                 "grid_controller_password":"c0tr011er",
                 "description":"Xen grid for demo"}}))

resp = conn.getresponse()
if resp.status > 201:
    print 'Failed grid create - '
    print json.loads(resp.read())
else:
    print 'Grid created'

网格操作示例

可在网格上执行以下操作：开始、停止、重新启动、clearFailure、applyHotfixes、removeNodes。 以下示例说明了如何在 BFC API 中启动网格。 使用其他网格操作的参数替换启动参数。

Curl 示例：

curl -k -v -X POST https://$BFC_HOST:8443/BFC/grids/$GRID_NAME/operations/start \
  -H "Content-Type:application/json" \
  -H "Authorization:$BFC_SESSION"

Python 示例：

session = get_session()
conn = HTTPSConnection(bfcHost + ':8443')
gridName = 'productionApiTest'
operation = 'start'
conn.connect()
conn.request(method='POST',
             url='/BFC/grids/' + gridName + "/operations/" + operation ,
             headers={'Content-Type':'application/json',
                      'Authorization':session})

resp = conn.getresponse()
if resp.status > 202:
    print 'Failed grid operation  - '
    print json.loads(resp.read())
else:
    print 'Operation successful'

网格更新示例

以下示例介绍了网格更新，即说明发生了更改，并且 xen 目标节点数从 1 改成了 2。

Curl 示例：

curl -k -v -X PUT https://$BFC_HOST:8443/BFC/grids/$GRID_NAME \
  -H "Content-Type:application/json" \
  -H "Authorization:$BFC_SESSION" \
  -d "{\"grid\":{\"description\":\"New Description\",
                 \"xen_config\":{\"grid_server_configuration\":{\"min\":1,
                                                   \"target\":2,
                                                   \"max\":2,
						   \"selection_criteria\":[]}}}}"

Python 示例：

session = get_session()
conn = HTTPSConnection(bfcHost + ':8443')
gridName = 'productionApiTest'
conn.connect()
conn.request(method='PUT',
             url='/BFC/grids/' + gridName,
             headers={'Content-Type':'application/json',
                      'Authorization':session},
             body = json.dumps({"grid":{
                 "xen_config":{"grid_server_configuration":{
                        "min":1,
                        "target":2,
                        "max":2,
                        "selection_criteria":[]}},
                 "description":"New Description"}}))

resp = conn.getresponse()
if resp.status > 201:
    print 'Failed grid create - '
    print json.loads(resp.read())
else:
    print 'Grid created'

网格删除示例

以下示例说明了如何使用 BFC API 删除网格。

Curl 示例：

curl -k -v -X DELETE https://$BFC_HOST:8443/BFC/grids/$GRID_NAME \
  -H "Content-Type:application/json" \
  -H "Authorization:$BFC_SESSION"

Python 示例：

session = get_session()
gridName = 'productionApiTest'
conn = HTTPSConnection(bfcHost + ':8443')
conn.connect()
conn.request(method='DELETE',
             url='/BFC/grids/' + gridName,
             headers={'Content-Type':'application/json',
                      'Authorization':session})
resp = conn.getresponse()
if resp.status > 202:
    print 'Failed grid delete - '
    print json.loads(resp.read())
else:
    print 'Grid deleted'
