Python RESTful Client

A Python RESTful API client is provided along with a REST test library to aid in test development of RESTful services.

Example RESTful Client Program:

>>> import urllib2
>>> import json

>>> request = urllib2.Request("https://zfsssa.example:215/api/access/v1", "")
>>> request.add_header("X-Auth-User", "rest_user")
>>> request.add_header("X-Auth-Key", "password")
>>> response = urllib2.urlopen(request)
>>> response.getcode()
201

>>> info = response.info()
>>>
        opener = urllib2.build_opener(urllib2.HTTPHandler)
>>> opener.addheaders = [("X-Auth-Session", info.getheader("X-Auth-Session")),
... ('Content-Type', 'application/json'), ('Accept', 'application/json')]

The opener can then be used to open requests that are already pre-authenticated and ready to send/receive JSON data.

Get a Resource

The following Python code can be used to get data from any RESTful API resource.

Example GET:

>>> request = urllib2.Request("https://zfs-storage.example.com:215/api/network/v1/routes")
>>> response = opener.open(request)
>>> response.getcode()
200
>>> body = json.loads(response.read())
>>> print json.dumps(body, sort_keys=True, indent=4)
{
    "routes": [

            {
            "destination": "ipaddr-0",
            "family": "IPv4",

            "gateway": "ipaddr-1",
            "href":
            "/api/network/v1/routes/ixgbe0,ipaddr-0,ipaddr-1",

            "interface": "ixgbe0",
            "mask": 0,
            "type": "static"

            }
    ]
}

Create a Resource

Example Python code to create a new resource:

>>> action = {'category': 'network'}
>>> post_data = json.dumps(action)
>>> request = urllib2.Request("https://zfs-storage.example.com:215/api/alert/v1/actions", post_data)
>>> request.add_header('Content-Type', 'application/json')

>>> response = opener.open(request)
>>> response.getcode()
201
>>> response.info().getheader('Location')
'/api/alert/v1/actions/actions-001'
>>> body = json.loads(response.read())
>>> print json.dumps(body, sort_keys=True, indent=4)
{

        "actions": {
        "category": "network",
        "datalink_failed": true,

        "datalink_ok": true,
        "href":
        "/api/alert/v1/actions/actions-001",

        "ip_address_conflict": true,

        "ip_address_conflict_resolved": true,

        "ip_interface_degraded": true,
        "ip_interface_failed":
        true,
        "ip_interface_ok": true,

        "network_port_down": true,
        "network_port_up":
        true
    }
}

Modify a Resource

Example Python code to modify an existing resource:

>>> put_data = '{"ip_address_conflict_resolved": false}'
>>>
        request = urllib2.Request("https://zfs-storage.example.com:215/api/alert/v1/actions/actions-001", put_data)
>>> request.add_header('Content-Type', 'application/json')
>>> request.get_method = lambda: 'PUT'

>>> response = opener.open(request)
>>> response.getcode()
202
>>> body = json.loads(response.read())
>>> print json.dumps(body, sort_keys=True, indent=4)
{

        "actions": {
        "category": "network",
        "datalink_failed": true,

        "datalink_ok": true,
        "href":
        "/api/alert/v1/actions/actions-001",

        "ip_address_conflict": true,

        "ip_address_conflict_resolved": false,

        "ip_interface_degraded": true,
        "ip_interface_failed":
        true,
        "ip_interface_ok": true,

        "network_port_down": true,
        "network_port_up":
        true
    }
}

Delete an Existing Resource

Example Python code to delete an existing resource:

>>> request = urllib2.Request("https://zfs-storage.example.com:215/api/alert/v1/actions/actions-001")
>>> request.get_method = lambda: 'DELETE'
>>> response = opener.open(request)
>>> response.getcode()
