Curl Rest Client

Language:

Curl clients must use curl version 7.34.0 or higher. Two common CLI-based HTTP clients are wget and curl. This section shows several examples of using curl to make RESTful API calls and similar functionality can be accomplished using wget.

Get Resource Data

This example shows how to use a simple HTTP GET request to obtain some JSON data:

> curl --user ${USER}:${PASSWORD} -k -i https://zfssa.example.com:215/api/nas/v1/pools/gold

    }
 }

Create a New Resource

This example shows how to send JSON data in a request to create a new resource:

$ curl --user ${USER}:${PASSWORD} -s -k -i -X POST -d @-  \
  -H "Content-Type: application/json" \
  https://zfssa-host.example.com:215/api/user/v1/users <<JSON
> {"logname": "rest_user",
>  "fullname": "REST User",
>  "initial_password": "letmein"}
> JSON

         "login_screen": "status/dashboard",
         "session_timeout": 15,
         "advanced_analytics": false,
         "keys": {}
      }
   }
}

Modify an Existing Resource

This example modifies a user's session timeout:

% curl --user larry:letmein -3 -s -k -i -X PUT \
  -H "Content-Type: application/json" -d @-  \
  https://tanana:215/api/appliance/v1/users/larry/preferences <<JSON
> {"session_timeout":60}
> JSON

        "session_timeout": 60,
        "advanced_analytics": false,
        "keys": {}
    }
}

Delete an Existing Resource

This command removes a user from the system:

curl --user ${USER}:${PASSWORD} -s -k -i -X DELETE  https://tanana:215/api/appliance/v1/users/jschwartz
