Glusto Simple REST Client¶

Glusto provides simple methods for basic REST API get, post, put, and delete functionality.

Making REST API Requests¶

Glusto supports the four basic REST API request types.

GET
POST
PUT
DELETE

Making a GET Request¶

To submit a GET request to a url, use the rest_get() method.

>>> g.rest_get('http://httpbin.org/get')

Making a POST Request¶

To submit a POST request to a url, use the rest_post() method.

>>> g.rest_post('http://httpbin.org/post', data={'this': 'yada1', 'that': 'yada2'})

Making a PUT Request¶

To submit a PUT request to a url, use the rest_put() method.

>>> g.rest_put('http://httpbin.org/put', data={'this': 'yada1', 'that': 'yada2'})

Making a DELETE Request¶

To submit a DELETE request to a url, use the rest_delete() method.

>>> g.rest_delete('http://httpbin.org/delete', data={'this': 'yada1', 'that': 'yada2'})

Handling the Request Response¶

Glusto provides the return in a tuple similar to the SSH calls in the glusto.Connectible class.

>>> g.rest_get('http://192.168.1.112:8081/hello')
(0, 'HelloWorld from GlusterFS Application', None)

The returned tuple consists of the return code, the response output, and the response error.

Note

The return code is the standard HTTP code returned by the web server on server response error (e.g., 404), otherwise returns zero for a successful request.

Using the Request Response as Config¶

The output of the response will be in string format.

YAML Formatted Text¶

If the string is yaml formatted text, it can be converted into a dictionary object using the load_yaml_string() method.

>>> g.rest_get('http://192.168.1.112:8081/clusters')
(0, '{"clusters":["e2effa75a5a50560c3250b67cf71b465"]}\n', None)

>>> rcode, rout, rerr = g.rest_get('http://192.168.1.112:8081/clusters')[1]
>>> g.load_yaml_string(rout)
{'clusters': ['e2effa75a5a50560c3250b67cf71b465']}

JSON Formatted Text¶

If the string is json formatted text, it can be converted into a dictionary object using the load_json_string() method.

>>> g.rest_get('http://192.168.1.112:8081/clusters')
(0, '{"clusters":["e2effa75a5a50560c3250b67cf71b465"]}\n', None)

>>> rcode, rout, rerr = g.rest_get('http://192.168.1.112:8081/clusters')[1]
>>> g.load_json_string(out)
{u'clusters': [u'e2effa75a5a50560c3250b67cf71b465']}
