Chunked transfer encoding is a mechanism for transferring data in an HTTP request. With this mechanism, the data is sent in a series of chunks. Requests supports chunked transfer encoding, for both outgoing and incoming requests. In order to send a chunk encoded request, we need to supply a generator for your body.

The usage is shown in the following example:

>>> def generator():
...     yield "Hello "
...     yield "World!"
...
>>> requests.post('http://example.com/some/chunked/url/path',
                  data=generator())
