    Sends an HTTP request.

    **Parameters:**

    * **method** - HTTP method for the new `Request` object: `GET`, `OPTIONS`,
    `HEAD`, `POST`, `PUT`, `PATCH`, or `DELETE`.
    * **url** - URL for the new `Request` object.
    * **params** - *(optional)* Query parameters to include in the URL, as a
    string, dictionary, or sequence of two-tuples.
    * **content** - *(optional)* Binary content to include in the body of the
    request, as bytes or a byte iterator.
    * **data** - *(optional)* Form data to include in the body of the request,
    as a dictionary.
    * **files** - *(optional)* A dictionary of upload files to include in the
    body of the request.
    * **json** - *(optional)* A JSON serializable object to include in the body
    of the request.
    * **headers** - *(optional)* Dictionary of HTTP headers to include in the
    request.
    * **cookies** - *(optional)* Dictionary of Cookie items to include in the
    request.
    * **auth** - *(optional)* An authentication class to use when sending the
    request.
    * **proxy** - *(optional)* A proxy URL where all the traffic should be routed.
    * **proxies** - *(optional)* A dictionary mapping proxy keys to proxy URLs.
    * **timeout** - *(optional)* The timeout configuration to use when sending
    the request.
    * **follow_redirects** - *(optional)* Enables or disables HTTP redirects.
    * **verify** - *(optional)* SSL certificates (a.k.a CA bundle) used to
    verify the identity of requested hosts. Either `True` (default CA bundle),
    a path to an SSL certificate file, an `ssl.SSLContext`, or `False`
    (which will disable verification).
    * **cert** - *(optional)* An SSL certificate used by the requested host
    to authenticate the client. Either a path to an SSL certificate file, or
    two-tuple of (certificate file, key file), or a three-tuple of (certificate
    file, key file, password).
    * **trust_env** - *(optional)* Enables or disables usage of environment
    variables for configuration.

    **Returns:** `Response`

    Usage:

    ```

    >>> response
    <Response [200 OK]>
