classmethod get_read_strategy(response)

Return the appropriate algorithm of reading response.

Returns:chunked, length, close. Return type:str

read_body(request, response, file=None, raw=False)

Read the response’s content body.

Coroutine.

read_response(response=None)

Read the response’s HTTP status line and header fields.

Coroutine.

reconnect()

Connect the connection if needed.

Coroutine.

write_body(file, length=None)

Send the request’s content body.

Coroutine.
