    Provides behavior for making common types of HTTP request methods and
    decides which type of request field encoding to use.

    Specifically,

    :meth:`.request_encode_url` is for sending requests whose fields are
    encoded in the URL (such as GET, HEAD, DELETE).

    :meth:`.request_encode_body` is for sending requests whose fields are

    (such as for POST, PUT, PATCH).

    :meth:`.request` is for making any kind of request, it will look up the
    appropriate encoding format and use one of the above two methods to make
    the request.

        """
        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
        :func:`urllib3.encode_multipart_formdata` is used to encode
        the payload with the appropriate content type. Otherwise
        :func:`urllib.parse.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()),

                              '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 mimic 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.

"""
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 pip._vendor.urllib3 import PoolManager
    from pip._vendor.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.

    Notably it will raise an :class:`AppEnginePlatformError` if:

          support is available.

        * If a response size is more than 32 megabytes.
        * If you use an unsupported request method such as OPTIONS.

    Beyond those cases, it will raise normal urllib3 errors.
