""" | |
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. | |
.. note:: | |
More commonly, it's appropriate to use a convenience method provided | |
by :class:`.RequestMethods`, such as :meth:`request`. | |
.. note:: | |
`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. | |
: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 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. | |
:param retries: | |
Configure the number of retries to allow before raising a | |
:class:`~urllib3.exceptions.MaxRetryError` exception. | |
Pass ``None`` to retry until you receive a response. 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 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. | |
: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 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. | |
: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. | |
:param int body_pos: | |
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. | |
:param \\**response_kw: | |
Additional parameters are passed to | |

""" | |
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. | |
.. note:: | |
More commonly, it's appropriate to use a convenience method provided | |
by :class:`.RequestMethods`, such as :meth:`request`. | |
.. note:: | |
`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. | |
: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 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. | |
:param retries: | |
Configure the number of retries to allow before raising a | |
:class:`~urllib3.exceptions.MaxRetryError` exception. | |
Pass ``None`` to retry until you receive a response. 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 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. | |
: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 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. | |
: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. | |
:param int body_pos: | |
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. | |
:param \\**response_kw: | |
Additional parameters are passed to | |
:meth:`urllib3.response.HTTPResponse.from_httplib` | |
