- POST requests, see HTTPConnectionPool.post_url for
- more convenience).

- Dictionary of custom headers to send, such as User-Agent,

- 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.
-
- :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
-
- :param 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.
-
- :param 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.

- If specified, overrides the default timeout for this one
- request. It may be a float (in seconds) or an instance of
- :class:`urllib3.util.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.
-
- :param 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)``.

- :param 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.

- Position to seek to in file-like body in the event of a retry or

-This module provides a pool manager that uses Google App Engine's
-`URLFetch Service <https://cloud.google.com/appengine/docs/python/urlfetch>`_.
-
-Example usage::
-
- from urllib3 import PoolManager
- from urllib3.contrib.appengine import AppEngineManager, is_appengine_sandbox
-
- if is_appengine_sandbox():
- # AppEngineManager uses AppEngine's URLFetch API behind the scenes
- http = AppEngineManager()
- else:
- # PoolManager uses a socket-level API behind the scenes
- http = PoolManager()
-
- r = http.request('GET', 'https://google.com/')
-
-There are `limitations <https://cloud.google.com/appengine/docs/python/\
-urlfetch/#Python_Quotas_and_limits>`_ to the URLFetch service and it may not be
-the best choice for your application. There are three options for using
-urllib3 on Google App Engine:
-
-1. You can use :class:`AppEngineManager` with URLFetch. URLFetch is
- cost-effective in many circumstances as long as your usage is within the
- limitations.
-2. You can use a normal :class:`~urllib3.PoolManager` by enabling sockets.
- Sockets also have `limitations and restrictions
- <https://cloud.google.com/appengine/docs/python/sockets/\
- #limitations-and-restrictions>`_ and have a lower free quota than URLFetch.
- To use sockets, be sure to specify the following in your ``app.yaml``::
-
- env_variables:
- GAE_USE_SOCKETS_HTTPLIB : 'true'
-
-3. If you are using `App Engine Flexible
-<https://cloud.google.com/appengine/docs/flexible/>`_, you can use the standard
-:class:`PoolManager` without any configuration or special environment variables.

-SSL with SNI_-support for Python 2. Follow these instructions if you would
-like to verify SSL certificates in Python 2. Note, the default libraries do
-*not* do certificate checking; you need to do additional work to validate
-certificates yourself.
-
-This needs the following packages installed:
-
-* pyOpenSSL (tested with 16.0.0)
-* cryptography (minimum 1.3.4, from pyopenssl)
-* idna (minimum 2.0, from cryptography)
-
-However, pyopenssl depends on cryptography, which depends on idna, so while we
-use all three directly here we end up having relatively few packages required.
-
-You can install them with the following command:
-
- pip install pyopenssl cryptography idna
-
-To activate certificate checking, call
-:func:`~urllib3.contrib.pyopenssl.inject_into_urllib3` from your Python code
-before you begin making HTTP requests. This can be done in a ``sitecustomize``
-module, or at any other time before your application begins using ``urllib3``,
-like this::
-
- try:
- import urllib3.contrib.pyopenssl
- urllib3.contrib.pyopenssl.inject_into_urllib3()
- except ImportError:
- pass
-
-Now you can use :mod:`urllib3` as you normally would, and it will support SNI
-when the required modules are installed.
-
-Activating this module also has the positive side effect of disabling SSL/TLS
-compression in Python 2 (see `CRIME attack`_).
-
-If you want to configure the default list of supported cipher suites, you can
-set the ``urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST`` variable.

-SecureTranport support for urllib3 via ctypes.
-
-This makes platform-native TLS available to urllib3 users on macOS without the
-use of a compiler. This is an important feature because the Python Package
-Index is moving to become a TLSv1.2-or-higher server, and the default OpenSSL
-that ships with macOS is not capable of doing TLSv1.2. The only way to resolve
-this is to give macOS users an alternative solution to the problem, and that
-solution is to use SecureTransport.
-
-We use ctypes here because this solution must not require a compiler. That's
-because pip is not allowed to require a compiler either.
-
-This is not intended to be a seriously long-term solution to this problem.
-The hope is that PEP 543 will eventually solve this issue for us, at which
-point we can retire this contrib module. But in the short term, we need to
-solve the impending tire fire that is Python on Mac without this kind of
-contrib module. So...here we are.
-
-To use this module, simply import and inject it::
-
- import urllib3.contrib.securetransport
- urllib3.contrib.securetransport.inject_into_urllib3()
-
-Happy TLSing!

- Make a request using :meth:`urlopen` with the ``fields`` encoded in
- the body. This is useful for request methods like POST, PUT, PATCH, etc.
-
- When ``encode_multipart=True`` (default), then
- :meth:`urllib3.filepost.encode_multipart_formdata` is used to encode
- the payload with the appropriate content type. Otherwise
- :meth:`urllib.urlencode` is used with the
- 'application/x-www-form-urlencoded' content type.
-
- Multipart encoding must be used when posting files, and it's reasonably
- safe to use it in other times too. However, it may break request
- signing, such as with OAuth.
-
- Supports an optional ``fields`` parameter of key/value strings AND
- key/filetuple. A filetuple is a (filename, data, MIME type) tuple where
- the MIME type is optional. For example::
-
- fields = {
- 'foo': 'bar',
- 'fakefile': ('foofile.txt', 'contents of foofile'),
- 'realfile': ('barfile.txt', open('realfile').read()),
- 'typedfile': ('bazfile.bin', open('bazfile').read(),
- 'image/jpeg'),
- 'nonamefile': 'contents of nonamefile field',
- }
-
- When uploading a file, providing a filename (the first parameter of the
- tuple) is optional but recommended to best mimick behavior of browsers.
-
- Note that if ``headers`` are supplied, the 'Content-Type' header will
- be overwritten because it depends on the dynamic random boundary string
- which is used to compose the body of the request. The random boundary
- string can be explicitly set with the ``multipart_boundary`` parameter.

- :param int total:
- Total number of retries to allow. Takes precedence over other counts.
-
- Set to ``None`` to remove this constraint and fall back on other
- counts. It's a good idea to set this to some sensibly-high value to
- account for unexpected edge cases and avoid infinite retry loops.
-
- Set to ``0`` to fail on the first retry.
-
- Set to ``False`` to disable and imply ``raise_on_redirect=False``.
-
- :param int connect:
- How many connection-related errors to retry on.
-
- These are errors raised before the request is sent to the remote server,
- which we assume has not triggered the server to process the request.
-
- Set to ``0`` to fail on the first retry of this type.
-
- :param int read:
- How many times to retry on read errors.

- request may have side-effects.
-
- Set to ``0`` to fail on the first retry of this type.
-
- :param int redirect:
- How many redirects to perform. Limit this to avoid infinite redirect
- loops.
-
- A redirect is a HTTP response with a status code 301, 302, 303, 307 or

-
- :param iterable method_whitelist:
- Set of uppercased HTTP method verbs that we should retry on.
-
- By default, we only retry on methods which are considered to be
- idempotent (multiple requests with the same parameters end with the
- same state). See :attr:`Retry.DEFAULT_METHOD_WHITELIST`.
-
- Set to a ``False`` value to retry on any verb.
-
- :param iterable status_forcelist:
- A set of integer HTTP status codes that we should force a retry on.
- A retry is initiated if the request method is in ``method_whitelist``
- and the response status code is in ``status_forcelist``.
-
- By default, this is disabled with ``None``.
-
- :param float backoff_factor:
- A backoff factor to apply between attempts after the second try
- (most errors are resolved immediately by a second try without a
- delay). urllib3 will sleep for::
-
- {backoff factor} * (2 ^ ({number of total retries} - 1))

- if status falls in ``status_forcelist`` range and retries have
- been exhausted.

-
- Defaults to None.
-
- :type total: integer, float, or None
-
- :param connect:
- The maximum amount of time to wait for a connection attempt to a server
- to succeed. Omitting the parameter will default the connect timeout to
- the system default, probably `the global default timeout in socket.py
- <http://hg.python.org/cpython/file/603b4d593758/Lib/socket.py#l535>`_.

- :type read: integer, float, or None

- .. note::
-
- Many factors can affect the total amount of time for urllib3 to return
- an HTTP response.
-
- For example, Python's DNS resolver does not obey the timeout specified
- on the socket. Other factors that can affect total request time include
- high CPU load, high swap, the program running at a low priority level,
- or other behaviors.
-
- In addition, the read and total timeouts only measure the time between
- read operations on the socket connecting the client and the server,
- not the total amount of time for the request to return a complete
- response. For most requests, the timeout is raised because the server
- has not sent the first byte in the specified time. This is not always
- the case; if a server streams one byte every fifteen seconds, a timeout
- of 20 seconds will not trigger, even though the request will take
- several minutes to complete.
-
- If your goal is to cut off any request after a set amount of wall clock
- time, consider having a second "watcher" thread to cut off a slow
- request.
