我正在运行我的服务器代码，该服务器代码似乎能够将图片发送到客户端，但是看起来只发送了一个图片文件，一旦手动打开该文件就全黑了。此外，客户端在尝试显示收到的图片时会出错。

我试图将字节转换回图片，这就是给我错误的部分。

import cv2 #SERVER
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......")
print(type(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')
        l = f.read(1024)
        #while (l):
        c.send(l)
        print('Sent ',repr(l))
        #l = f.read(1024)
        f.close()
        print(pics,"sdfasdfsadadfsafsas")
        print(type(f),type(l))

    print('Done sending')
    c.send('Thank you for connecting'.encode())

import socket #CLIENT
from typing import Optional,Any
import cv2
from PIL import Image
import io
import pickle
host =  "127.0.0.1"
port = 5000

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect((host,port))
s.send('Hello server!'.encode())

with open('received_file.png','wb') as f:
    print('file is open')
    print('receiving data...')
    data = s.recv(1024)
    print('data=%s',data)
    f.write(data)
    print('Successfully get the files')
    print('connection closed')
    print(type(data))
    print(len(data))
    image = Image.open(io.BytesIO(data))
    image.show()
s.close()

这是来自客户端的错误，但是请注意，我必须在此处缩小代码以匹配布局，因此此错误消息中的第35行可能对应于另一行。

Traceback (most recent call last):
