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` """ parsed_url = parse_url(url) destination_scheme = parsed_url.scheme if headers is None: headers = self.headers if not isinstance(retries, Retry): retries = Retry.from_int(retries, redirect=redirect, default=self.retries) if release_conn is None: release_conn = response_kw.get("preload_content", True) # Check host if assert_same_host and not self.is_same_host(url): raise HostChangedError(self, url, retries) # Ensure that the URL we're connecting to is properly encoded if url.startswith("/"): url = six.ensure_str(_encode_target(url)) else: url = six.ensure_str(parsed_url.url) conn = None # Track whether `conn` needs to be released before # returning/raising/recursing.

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` """ parsed_url = parse_url(url) destination_scheme = parsed_url.scheme if headers is None: headers = self.headers if not isinstance(retries, Retry): retries = Retry.from_int(retries, redirect=redirect, default=self.retries) if release_conn is None: release_conn = response_kw.get("preload_content", True) # Check host if assert_same_host and not self.is_same_host(url): raise HostChangedError(self, url, retries) # Ensure that the URL we're connecting to is properly encoded if url.startswith("/"): url = six.ensure_str(_encode_target(url)) else: url = six.ensure_str(parsed_url.url) conn = None # Track whether `conn` needs to be released before # returning/raising/recursing.
