I'm writing a tcp web client and web server in python (and I'm new to python and sockets/networking). Everything is working but I'd like to implement the HTTP/1.1 protocol rather than HTTP/1.0 and I can't get a response of 1.1 no matter what I do. I read that it requires a host field, but maybe I'm doing something else wrong.

Here is my GET request

request = "GET "   path   " HTTP/1.1"   "\r\nHost: "   HOST   "\r\n\r\n"

Here is my response

"b'HTTP/1.0 200 OK

I'm using BaseHTTPRequestHandler for my web server. Is that the problem maybe?

CodePudding user response：

You should set the protocol_version to 'HTTP/1.1' in your BaseHTTPRequestHandler implementation:

protocol_version This specifies the HTTP protocol version used in responses. If set to 'HTTP/1.1', the server will permit HTTP persistent connections; however, your server must then include an accurate Content-Length header (using send_header()) in all of its responses to clients. For backwards compatibility, the setting defaults to 'HTTP/1.0'.

CodePudding user response：

Try: request = f"GET / HTTP/1.1\r\nHost: {HOST}:{PORT}\r\n\r\n".encode()

insert host in {HOST} and port in {PORT}.
