POST request using python-maas-client

Question

How can we do the post request to maas api using the python-maas-client.

I am getting the details from maas api using the maas-client by the following code.

print maas_access.get(u"networks").read()
print maas_access.get(u"users").read()

But when i try to post a request I am getting the error. code is below

data = {'username':'murali','email':'muralidharan.s@poornam.com','password':'murali','is_superuser': 0}
maas_access.post(u"users/", "new", data)
Traceback (most recent call last):
  File "api.py", line 48, in <module>
    maas_access.post(u"users/", "new", data)
  File "/usr/lib/python2.7/dist-packages/apiclient/maas_client.py", line 250, in post
    url, method="POST", headers=headers, data=body)
  File "/usr/lib/python2.7/dist-packages/apiclient/maas_client.py", line 116, in dispatch_query
    res = urllib2.urlopen(req)

    return _opener.open(url, data, timeout)

    response = meth(req, response)

    'http', request, response, code, msg, hdrs)

    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 400: BAD REQUEST

 data = {'username':'murali','email':'muralidharan.s@poornam.com','password':'murali','is_superuser': 0}
maas_access.post(u"users/", data)
Traceback (most recent call last):

    return quote(s, safe)
  File "/usr/lib/python2.7/urllib.py", line 1286, in quote
    if not s.rstrip(safe):
AttributeError: 'dict' object has no attribute 'rstrip'

Is I am missing some thing or the data that i providing is wrong ? Please help me

Answer 1

While there is no actual documentation for the current form of the apiclient, reading the source for the signature of the post() method:

def post(self, path, op, as_json=False, **kwargs):
    """Dispatch POST method `op` on `path`, with the given parameters.

    :param as_json: Instead of POSTing the content as multipart/form-data
        POST it as application/json
    :return: The result of the dispatch_query call on the dispatcher.
    """

That suggests that any data you provide needs to be submitted as kwargs; as below:

maas_access.post(u"users/", "new", **data)

There is one more problem with your data, though, which is that you are submitting an integer as an argument; instead, submit it as the string '0':

data = {'username':'murali', 'email':'muralidharan.s@poornam.com', 
     'password':'murali', 'is_superuser': '0'}
maas_access.post(u"users/", "new", **data)

Finally, note that that API is insecure as it supplies the password as plaintext, as indicated in the API documentation.

See http://blog.allenap.me/2013/06/workaround-for-uploading-files-to-maas.html for a more complete example of using the client's post() API.

Answer 2

sshKeys = {"key": [keyValue]}
maas_access.post(u"account/prefs/sshkeys/", "new", **sshKeys)

The above code will post the ssh key into the maas using maas-api. But in case of user it is not working. Still getting 400 error
