I need to build a http server without using an HTTP library.
I have the server running and an html page beeing loaded but my <img src="..."/>
tags are not beeing loaded, I recive the call but cannot preset the png/JPEG in the page.
# Define socket host and port
SERVER_HOST = '0.0.0.0'
SERVER_PORT = 8000
# Create socket
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
server_socket.bind((SERVER_HOST, SERVER_PORT))
server_socket.listen(1)
print('Listening on port %s ...' % SERVER_PORT)
while True:
# Wait for client connections
client_connection, client_address = server_socket.accept()
# Handle client request
request = client_connection.recv(1024).decode()
content = handle_request(request)
# Send HTTP response
if content:
response = 'HTTP/1.1 200 OK\n\n'
response += content
else:
response = 'HTTP/1.1 404 NOT FOUND\n\nFile Not Found'
client_connection.sendall(response.encode())
client_connection.close()
# Close socket
server_socket.close()
def handle_request(request):
http = HttpHandler.HTTPHandler
# Parse headers
print(request)
headers = request.split('\n')
get_content = headers[0].split()
accept = headers[6].split()
type_content = accept[1].split('/')
try:
# Filename
filename = get_content[1]
if get_content[0] == "GET":
content = http.get(None, get_content[1], type_content[0])
return content
except FileNotFoundError:
return None
class HTTPHandler:
def get(self, args, type):
if args == '/':
args = '/index.html'
fin = open('htdocs' + args)
if type != "image":
fin = open('htdocs/' + args)
if type == "image":
fin = open('htdocs/' + args, 'rb')
# Read file contents
content = fin.read()
fin.close()
return content
Realize that I´m trying to make an HTTP 1.1, if you see anything out of pattern fell free to say thanks in advance.
Ended up like:
while True:
# Wait for client connections
client_connection, client_address = server_socket.accept()
# Handle client request
request = client_connection.recv(10240).decode()
content = handle_request(request)
# Send HTTP response
if content:
if str(content).find("html") > 0:
client_connection.send('HTTP/1.1 200 OK\n\n'.encode())
client_connection.send(content.encode())
else:
client_connection.send('HTTP/1.1 200 OK\r\n'.encode())
client_connection.send("Content-Type: image/jpeg\r\n".encode())
client_connection.send("Accept-Ranges: bytes\r\n\r\n".encode())
client_connection.send(content)
else:
response = 'HTTP/1.1 404 NOT FOUND\r\nFile Not Found'
client_connection.close()
And the Get method like:
class HTTPHandler:
def get(self, args, type):
if args == '/':
args = '/index.html'
fin = open('htdocs' + args)
if type != "image":
fin = open('htdocs/' + args)
if type.find("html") == -1:
image_data = open('htdocs/' + args, 'rb')
bytes = image_data.read()
# Content-Type: image/jpeg, image/png \n\n
content = bytes
fin.close()
return content
# Read file contents
content = fin.read()
fin.close()
return content
