UnicodeDecodeError：“charmap”编解码器无法解码位置 328 中的字节 0x81：

Question

好的，所以我正在为我的房子制作云存储，但问题是它只接收 .txt 或只有文本的文件。我希望它接收 zip 文件图像和所有类型的文件，但是当我尝试发送 zip 文件或任何其他类型的文件时...我收到此错误。

Traceback (most recent call last):
  File "D:\Workspace\Code\Cloud Storage\client.py", line 45, in <module>
    file_data = in_file.read()
  File "C:\Users\Shashankh\AppData\Local\Programs\Python\Python39\lib\encodings\cp1252.py", line 23, in decode
    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 328: character maps to <undefined>

我确实收到了文件，但文件已损坏或为空。

这是我的代码。

client.py

import socket
import pyautogui
from tkinter import *
from tkinter import filedialog
import os



s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('192.168.0.108',4321))


root = Tk()
root.withdraw()

while True:
   confirm_send = pyautogui.confirm("Do you want to start file transfer?")
   if confirm_send == 'OK':
       warning = pyautogui.confirm("WARNING!: IF YOU HAVE ALREADY SENT THE FILE WITH THE SAME NAME... THE DATA MAY OVERWRITE AND MAY GET CORRUPTED. CHANGE YOUR FILENAME FOR SAFETY!")

       if warning == 'OK':

           prompt = pyautogui.prompt(text='Cloud Name', title='' , default='Enter your cloud storage folder name')
           if prompt == 'Shashankh':
               s.send(bytes('Shashankh','utf-8'))
           if prompt == 'Hari':
               s.send(bytes('Hari','utf-8'))

           if prompt == 'Prasanna':
               s.send(bytes('Prasanna','utf-8'))
           
           if prompt == None:
               exit()

           file = filedialog.askopenfilename()
           if file == 'Cancel':
               quit()

           file_name = os.path.basename(file)
           s.send(bytes(file_name,'utf-8'))
           open_file = (file, 'rb')        

           with open(file) as in_file:

               s.send(bytes(file_data,'utf-8'))

Answer 1

首先是精彩的节目！

您似乎在 client.py 文件的第 45 行中遗漏了一个关键字。如下
s.send(bytes(file_name,'utf-8')) 您必须提到一个称为编码的参数。这将访问编码格式（即utf-8）所以下面是更正的代码..
s.send(bytes(file_name,encoding='utf-8'))

希望它有效。我很想看到它起作用。
