This is my code:
# Process connections
print('Listening on port', port)
while True:
c, addr = s.accept()
print("Got connection from", addr)
msg = "<html></html>"
response_headers = {
'Content-Type': 'text/html; encoding=utf8',
'Content-Length': len(msg.encode(encoding="utf-8")),
'Connection': 'close',
}
response_headers_raw = ''.join('%s: %s\n' % (k, v) for k, v in response_headers.items())
response_proto = 'HTTP/1.1'
response_status = '200'
response_status_text = 'OK' # this can be random
# sending all this stuff
r = '%s %s %s' % (response_proto, response_status, response_status_text)
c.send(r.encode(encoding="utf-8"))
c.send(response_headers_raw.encode(encoding="utf-8"))
c.send('\n'.encode(encoding="utf-8")) # to separate headers from body
c.send(msg.encode(encoding="utf-8"))
c.close()
When I visit my local ip on the browser, I get an error page that says
ERR_CONNECTION_RESET
What am I doing wrong?
NOTE:
The full code snippet is here:
import socket
# Create socket object and set protocol
s = socket.socket(
socket.AF_INET, socket.SOCK_STREAM)
# Get name of local machine
host = socket.gethostname()
port = 80
# Bind
s.bind((host, port))
# Listen and set backlog (?)
s.listen(5)
# Process connections
print('Listening on port', port)
while True:
c, addr = s.accept()
print("Got connection from", addr)
msg = "<html></html>"
response_headers = {
'Content-Type': 'text/html; encoding=utf8',
'Content-Length': len(msg.encode(encoding="utf-8")),
'Connection': 'close',
}
response_headers_raw = ''.join('%s: %s\n' % (k, v) for k, v in response_headers.items())
response_proto = 'HTTP/1.1'
response_status = '200'
response_status_text = 'OK' # this can be random
# sending all this stuff
r = '%s %s %s' % (response_proto, response_status, response_status_text)
c.send(r.encode(encoding="utf-8"))
c.send(response_headers_raw.encode(encoding="utf-8"))
c.send('\n'.encode(encoding="utf-8")) # to separate headers from body
c.send(msg.encode(encoding="utf-8"))
c.close()

The problem is that HTTP headers need to be line separated by \r\n not just \n. See RFC 1945 - HTTP/1.0 Sec 2.2 and RFC 7230 - HTTP/1.1 Syntax and Routing Sec 3.
If you change this it will fix the problem.
import socket
# Create socket object and set protocol
s = socket.socket(
socket.AF_INET, socket.SOCK_STREAM)
# Get name of local machine
host = "127.0.0.1"
port = 8081
# Bind
s.bind((host, port))
# Listen and set backlog (?)
s.listen(5)
# Process connections
print('Listening on port', port)
while True:
c, addr = s.accept()
print("Got connection from", addr)
msg = "<html><body><h1>This is a test</h1><p>More content here</p></body></html>"
response_headers = {
'Content-Type': 'text/html; encoding=utf8',
'Content-Length': len(msg),
'Connection': 'close',
}
response_headers_raw = ''.join('%s: %s\r\n' % (k, v) for k, v in response_headers.items())
response_proto = 'HTTP/1.1'
response_status = '200'
response_status_text = 'OK' # this can be random
# sending all this stuff
r = '%s %s %s\r\n' % (response_proto, response_status, response_status_text)
c.send(r)
c.send(response_headers_raw)
c.send('\r\n') # to separate headers from body
c.send(msg.encode(encoding="utf-8"))
c.close()
