Man of few words said, directly to the question
One: The client total is divided into five large:
1. Create a client socket
2. to establish a connection and server socket
3. Send data
4. The transmission and reception
5. Close the client socket
2: Introduction of socket classes
Introducing the socket module
import socket
Create a client socket object
socket.socket (AddressFamily, Type)
send (data) indicates transmission data, data is binary data
recv (buffersize) represented by the reception data, buffersize length of the data is received per
Three: Program Development
socket Import
DEF main ():
# create a tcp client sockets
tcp_client_socket = socket.socket (socket.AF_INET, socket.SOCK_STREAM)
# establish and server applications to connect
tcp_client_socket.connect (( "192.168.28.1", 6666 ) )
# ready to send data
send_data = "Hello, you server!." encode ( "GBK")
# transmit data
tcp_client_socket.send (the send_data)
# receiving data, the maximum number of bytes of the received data 1024
recv_data = tcp_client_socket .recv (1024)
# returned binary data is directly sent by the server program
Print (recv_data)
# decodes the data
recv_content = recv_data.decode ( "GBK")
Print ( "as received data server:", recv_content)
# Close the socket
tcp_client_socket.close ()
IF the __name__ == '__main__':
main()
*****************************************
If the spectators do not understand it, I'll give you an example:
Create socket equivalent of buying a mobile phone
And establish a connection to the server equivalent of you who telephoned his
You open up the phone to send data equivalent to want what they are saying
Receive data you received the equivalent of what they are saying
Close the client is equivalent to the call is finished, hang up the phone
This is not good when it comes to understanding some of it?
***** ***** NOTE point
Windows encoding format is GBK
MAC OS encoding utf-8 format
Parameter 1: 'AF_INET', the type of address indicates IPv4
Parameter 2: 'SOCK_STREAM', represents TCP transport protocol type
