I am trying to create a client to connect to a server with given url address.
I used this way
host_ip = socket.gethostbyname('HOST_NAME')
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.bind(('127.0.0.1', 0))
sock.connect((host_ip, 8080))
but it printed the following error
OSError: [Errno 22] Invalid argument
Can someone explain me why is wrong and give me a solution?
You don't have to bind your socket, this is done server-side.
Here's the example code from the documentation for socket :
import socket
HOST = 'your-url.net' # The remote host
PORT = 8080 # The same port as used by the server
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.connect((HOST, PORT))
s.sendall(b'Hello, world')
data = s.recv(1024)
print('Received', repr(data))
This is a simple snippet, which connects to the server, sends some data, and prints the response.
binding the socket? This is used if you are the server.
