Sending an array through socket [Python]-CodePudding

I am reading two values i.e Data = [8, 10] on the server side and want to send it to the client side but on the client side i receive the data as "810".

Client Side:

import socket

try:
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except socket.error as err:
    print("Socket creation failed with error : ", err)

s.connect((socket.gethostname(), 9880))
print("connected to cloud.")

print(time.time(), ":\tSending request")
print(time.time(), ":\tWaiting for cloud's reply")

Data = []
for i in range(0,2):
    c = s.recv(128)      
    c_d = c.decode()
    print("Data: ",c_d)
    Data.append(c_d)

Server Side:

import socket
try:
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except socket.error as err:
    print("Socket creation failed with error : ", err)

s.bind((socket.gethostname(), 9880))
s.listen(5)

while True:
  print("Listening for connections ...")
  c, addr = s.accept()
  print("\tGot a connection!\n")


Data = [8, 10]    
for i in Data:
   s.send(str(i).encode())

CodePudding user response：

Try splitting up the numbers of the array you are sending over by including commas and spaces in the data stream. Instead of sending over just i, add a comma string after each value in the array.

import socket
try:
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
except socket.error as err:
    print("Socket creation failed with error : ", err)

s.bind((socket.gethostname(), 9880))
s.listen(5)

while True:
  print("Listening for connections ...")
  c, addr = s.accept()
  print("\tGot a connection!\n")


Data = [8, 10]    
for i in Data:
   s.send((str(i)   ", ").encode())

CodePudding user response：

In order to send and receive data you should use flask and socketio. The code below shows an example of what I mean. This method, you can send ANY type of data.

client.py:

Note: 'addr' is the address of the server you want to connect so you have to pass that when you are running client.py

import socketio

def connect(addr: str):
    socket_client = socketio.Client()
    socket_client.connect(addr)
    socket_client.send("hello")

    @socket_client.on('message')
    def on_message(msg):
        print('message recieved')
        i = input("Enter a message: ")
        socket_client.send(i)

server.py

from flask_socketio import SocketIO, send
from flask import Flask, request

app = Flask(__name__)

socketio = SocketIO(app, manage_session=False)

@socketio.on('message')
def handleMessage(msg):
    data = ['Resended message', msg]
    send(data, room=request.sid)

I hope this answers your question and you have learned something new.
