Get number of bytes during a request

In python, I'd like to recover the number of bytes during a request.

I did something like this (with requests module):

r = requests.get("https://google.fr/")

Not really this but this looks like. I'd like to know how many bytes the request requires and returns.

Thanks !!

The below code works for https:

import requests

url = 'https://google.fr/'

# use the 'auth' parameter to send requests with HTTP Basic Auth:
r = requests.get(url, auth=('user', 'pass'))

a = len(r.content)
print(a)

This is described in requests documentation shown here

http://docs.python-requests.org/en/master/user/advanced/

Be careful with your example though. python and requests in general have problems with SSL certificates. So the above

r=requests.get("https://google.fr/")

will give you 

SSLError: ("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",)

you could do 

r=requests.get("https://google.fr/",verify=False)

which is not recommended ... but ok atleast you will get something but you will not get a good content-length value in r.headers for the above site. Maybe some google specific issue.

in any case 

len(r.content)

should give you the length of the bytes object if 'Content-Length' is missing

If you use http it will work

r=requests.get("http://google.fr")
r.headers['Content-Length']

You will get '5433' or something like that Instead try all kinds of request on http://httpbin.org 

r=requests.get("http://httpbin.org/get")
r.headers['Content-Length']

you will get 256

which is the byte size that is returned

For info about the request sent to the server you use

r.requests.headers
