help with sending and receiving pics taken
#1
I am trying to send a few pics via socket from server to client.
I get this error on the client side, and I am not sure how to fix it.
Error:
Traceback (most recent call last): File "C:/Users/PycharmProjects/client-server/client.py", line 34, in <module> im = Image.open(fp) File "C:\Users\PycharmProjects\client-server\venv\lib\site-packages\PIL\Image.py", line 2818, in open raise IOError("cannot identify image file %r" % (filename if filename else fp)) OSError: cannot identify image file <_io.BufferedReader name='test.png'>
here are both of my codes
SERVER
import cv2
import time
import socket
import glob
import os

host =  "127.0.0.1"
port = 5000

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((host, port))
s.listen(5)
print("server started...")


path1 = (r"C:\Users\Desktop\opencvpics")


def readFileImages():
    st = os.path.join(path1, "*.png")
    print(st)
    return glob.glob(st)


list1=readFileImages()
print(list1, "list1......")
while True:
    c, addr = s.accept()
    print(f"connection from {addr} has been established !")
    c.send(bytes("welcome to the server".encode()))

    for pics in list1:
        f=open(pics, 'rb')
        while True:
            veri=f.read()
            if not veri:
                break
            s.send(veri)
        f.close()

data = s.recv(4096)
data_arr = pickle.loads(data)

newrow = numpy.asarray(data_arr)
myoutput = numpy.vstack([myoutput, newrow])

s.close()
import socket

from PIL import Image

import pickle


host =  "127.0.0.1"
port = 5000

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))



msg=s.recv(1024)
print(msg.decode())

fname="test.png"

fp = open(fname,'rb')

 # image
while True:

    strng = s.recv(1024)
    if not strng:
        break
    fp.write(strng)




im = Image.open(fp)

T= im.size
data=pickle.dumps(T)
s.send(data)
fp.close()
In the client code, I tried to move 'fp.close()'before 'im=Image.open(fp)' but it would then complain about dealing with a closed file.
