Question

我无法使用base64模块获得正确的路径，因为预期的输出应该像

C：\ Users \ User_Name \ Documents \ photos \ photo.png

我在以前的方法变量image_open中打印并得到了斜杠，但是当我对其进行解码和编码并尝试在对其进行编码后打印变量image_file时，最终在两者之间没有任何斜杠定义的路径...

import os
import base64
from tkinter import *
from PIL import ImageTK,Image

def pick_photo():
    global image
    global image_file_name
    #label_path_of_photo = tk.StringVar()
    ask_path_of_photo = filedialog.askopenfilename(initialdir = "C:/Users/User _Name/Documents/photos/",
                                     title = "Open File",
                                     filetypes = (("PNG","*.png"),("JPG","*jpg"),("All file","*.*")))   

    image_file_name =os.path.abspath(ask_path_of_photo)
    image_open = Image.open(general_path_to_photo + image_file_name)
    image = ImageTk.PhotoImage(image_open)
    image_show = tk.Label(root, image = image, textvariable = label_path_of_photo)
    image_show.grid(row = 0, column = 3, rowspan = 3, columnspan = 6, padx = 15, pady = 25)    

    path_decode(image_file_name)

def path_decode(image_file_name):
        decoded_path_of_image = base64.b64decode(image_file_name)
        print(decoded_path_of_image)
        encodig_path = base64.b64encode(decoded_path_of_image)
        print(encodig_path)

我希望输出按定义的斜线进行打印（在 io.path.abspath（ask_path_of_photo）中），我可以很好地打印输出，但是在打印时没有得到斜线编码后的字符串如果遇到其他错误，请帮我找出来

我认为您以错误的方式使用base64。

您应该首先创建filename.encode('utf-8')，然后再使用b64encode，而不是b64decode。然后在base64中获得字符串。

现在使用b64decode和.decode('utf-8)，您可以找回路径

import base64

def path_decode(filename):

    bytes_name = filename.encode('utf-8')
    encodig_path = base64.b64encode(bytes_name)
    print(encodig_path)

    bytes_name = base64.b64decode(encodig_path)
    filename = bytes_name.decode('utf-8')
    print(filename)


image_file_name = r'C:\Users\User_Name\Documents\photos\photo.png'
path_decode(image_file_name)

结果

b'QzpcVXNlcnNcVXNlcl9OYW1lXERvY3VtZW50c1xwaG90b3NccGhvdG8ucG5n'
C:\Users\User_Name\Documents\photos\photo.png

如何使用base64模块使用“ \”获取解码后的字符串
