class RequestMethods: """
Convenience mixin for classes who implement a :meth:`urlopen` method, such as :class:`urllib3.HTTPConnectionPool` and
:class:`urllib3.PoolManager`.
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` isfor sending requests whose fields are
encoded in the URL (such as GET, HEAD, DELETE).
:meth:`.request_encode_body` isfor sending requests whose fields are
encoded in the *body* of the request using multipart or www-form-urlencoded
(such asfor POST, PUT, PATCH).
:meth:`.request` isfor 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.
Initializer parameters:
:param headers:
Headers to include with all requests, unless other headers are given
explicitly. """

Make a request using :meth:`urlopen` with the appropriate encoding of
``fields`` based on the ``method`` used.
This is a convenience method that requires the least amount of manual
effort. It can be used in most situations, while still having the
option to drop down to more specific methods when necessary, such as
:meth:`request_encode_url`, :meth:`request_encode_body`, or even the lowest level :meth:`urlopen`.
:param method:
HTTP request method (such as GET, POST, PUT, etc.)

The URL to perform the request on.

Data to send in the request body, either :class:`str`, :class:`bytes`,
an iterable of :class:`str`/:class:`bytes`, or a file-like object.
:param fields:
Data to encode and send in the URL or request body, depending on ``method``.

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

Data to encode and send as JSON with UTF-encoded in the request body.

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 aswith 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::
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.
