class urllib3.contrib.ntlmpool.NTLMConnectionPool(user, pw, authurl, *args, **kwargs)

Bases: urllib3.connectionpool.HTTPSConnectionPool

Implements an NTLM authentication version of an urllib3 connection pool

scheme = 'https'
urlopen(method, url, body=None, headers=None, retries=3, redirect=True, assert_same_host=True)

Get a connection from the pool and perform an HTTP request. This is the lowest level call for making a request, so you’ll need to specify all the raw details.


More commonly, it’s appropriate to use a convenience method provided by RequestMethods, such as request().


release_conn will only behave as expected if preload_content=False because we want to make preload_content=False the default behaviour someday soon without breaking backwards compatibility.

  • method – HTTP request method (such as GET, POST, PUT, etc.)

  • url – The URL to perform the request on.

  • body – Data to send in the request body, either str, bytes, an iterable of str/bytes, or a file-like object.

  • headers – Dictionary of custom headers to send, such as User-Agent, If-None-Match, etc. If None, pool headers are used. If provided, these headers completely replace any pool-specific headers.

  • retries (Retry, False, or an int.) –

    Configure the number of retries to allow before raising a MaxRetryError exception.

    Pass None to retry until you receive a response. Pass a Retry object for fine-grained control over different types of retries. Pass an integer number to retry connection errors that many times, but no other types of errors. Pass zero to never retry.

    If False, then retries are disabled and any exception is raised immediately. Also, instead of raising a MaxRetryError on redirects, the redirect response will be returned.

  • redirect – If True, automatically handle redirects (status codes 301, 302, 303, 307, 308). Each redirect counts as a retry. Disabling retries will disable redirect, too.

  • assert_same_host – If True, will make sure that the host of the pool requests is consistent else will raise HostChangedError. When False, you can use the pool on an HTTP proxy and request foreign hosts.

  • timeout – If specified, overrides the default timeout for this one request. It may be a float (in seconds) or an instance of urllib3.util.Timeout.

  • pool_timeout – If set and the pool is set to block=True, then this method will block for pool_timeout seconds and raise EmptyPoolError if no connection is available within the time period.

  • release_conn – If False, then the urlopen call will not release the connection back into the pool once a response is received (but will release if you read the entire contents of the response such as when preload_content=True). This is useful if you’re not preloading the response’s content immediately. You will need to call r.release_conn() on the response r to return the connection back into the pool. If None, it takes the value of response_kw.get('preload_content', True).

  • chunked – If True, urllib3 will send the body using chunked transfer encoding. Otherwise, urllib3 will send the body using the standard content-length form. Defaults to False.

  • body_pos (int) – Position to seek to in file-like body in the event of a retry or redirect. Typically this won’t need to be set because urllib3 will auto-populate the value when needed.

  • **response_kw – Additional parameters are passed to urllib3.response.HTTPResponse.from_httplib()
