Python: cannot make a HTTPS request using SSL socket

Question

The code tells itself what it does. On all pages I tested I get status code 400. I tried to specify the certificate or SSL version too but the result is the same. I tried both closed and keep-alive as Connection for the msg sent.

import ssl,socket
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
page='google.com'
s=ssl.wrap_socket(s)
s.connect((page,443))
s.send(("GET / HTTP/1.1\r\nHost: "+page+"/\r\n\r\n").encode('UTF-8'))
while True:
        data=s.recv(4096)
        print(data)

Edit: I removed the / from the Host and it kinda helped, but now I get 301 Moved.

This is not a problem of SSL. In fact, the code 400 says that SSL worked perfectly since otherwise you would not be able to get a HTTP status code in the first place.

The problem is instead that your alleged HTTP request is not a fully correct HTTP request and the server rightly complains about a bad request. You specify google.com/ as domain inside the Host field instead of google.com.

Apart from that you fail to properly read the response since you don't stop reading if no more data are available, i.e. this is an endless loop.

Edit: I removed the / from the Host and it kinda helped, but now I get 301 Moved.

While it is a bad style to just change a question to something different (i.e. make it a moving target) the code 301 is actually the expected and correct answer from the server. It redirects you from https://google.com to https://www.google.com/.

I think it was one of the problems. I made an edit to the post regardless current state.

@uIM7AI9S: I've also answered this part but please stop making the question a moving target. If you have follow-up questions ask a new one instead. Your original one was fully answered.

there shouldn't be a trailing / on the Host value, e.g, try doing:

s.send(("GET / HTTP/1.1\r\nHost: "+page+"\r\n\r\n").encode('UTF-8'))

instead
