>>> req = httpx.Request('GET', 'https://www.example.com/')
>>> req
<Request [GET 'https://www.example.com/']>
>>> req.method
'GET'
>>> req.url
<URL 'https://www.example.com/'>

The following headers have automatic behavior with Requests instances...
Host- AHostheader must always be included on a request. This header is automatically populated from theurl, using theurl.netlocproperty.Content-Length- Requests including a request body must always include either aContent-Lengthheader or aTransfer-Encoding: chunkedheader. This header is automatically populated ifcontentis notNoneand the content is a known size.Transfer-Encoding- Requests automatically include aTransfer-Encoding: chunkedheader ifcontentis notNoneand the content is an unkwown size.Content-Type- Requests automatically include aContent-Typeheader ifcontentis set using the [Content Type] API.

>>> form = httpx.MultiPart(form={...}, files={...})
>>> with httpx.Request('POST', 'https://echo.encode.io/', content=form) as req:
>>>     req.headers
{...}
>>>     req.stream
<MultiPartStream [0% of ...MB]>
Including direct file uploads...

>>> with httpx.Request('POST', 'https://echo.encode.io/', content=file) as req:
>>>     req.headers
