"""
|
||
|
A convenience, top-level request method. It uses a module-global ``PoolManager`` instance.
|
||
|
Therefore, its side effects could be shared across dependencies relying on it.
|
||
|
To avoid side effects create a new ``PoolManager`` instance and use it instead.
|
||
|
The method does not accept low-level ``**urlopen_kw`` keyword arguments.
|
||
|
|
||
|
:param method:
|
||
|
HTTP request method (such as GET, POST, PUT, etc.)
|
||
|
|
||
|
:param url:
|
||
|
The URL to perform the request on.
|
||
|
|
||
|
:param body:
|
||
|
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 request body.
|
||
|
|
||
|
:param headers:
|
||
|
Dictionary of custom headers to send, such as User-Agent,
|
||
|
If-None-Match, etc.

||
|

|

|
If True, the response's body will be preloaded into memory.

:param bool decode_content:
|
||
|
If True, will attempt to decode the body based on the
|
||
|
'content-encoding' header.
|
||
|
|
||
|
: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 retries:
|
||
|
Configure the number of retries to allow before raising a
|
||
|
:class:`~urllib3.exceptions.MaxRetryError` exception.
|
||
|
|
||
|
If ``None`` (default) will retry 3 times, see ``Retry.DEFAULT``. Pass a
|
||
|
:class:`~urllib3.util.retry.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.
|
||
|
|
||
|
:type retries: :class:`~urllib3.util.retry.Retry`, False, or an int.
|
||
|
|
||
|
:param timeout:
|
||
|
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`.
|
||
|
|
||
|
:param json:
|
||
|
Data to encode and send as JSON with UTF-encoded in the request body.
|
||
|
The ``"Content-Type"`` header will be set to ``"application/json"``
|
||
|
unless specified otherwise.
