python - 使用 tktinter 输入获取字符串 URL 和下载文件夹

问题描述

我制作了一个脚本，该脚本获取一个包含整个 mp3 专辑的页面并下载每首歌曲。如果我在代码中插入所需的数据，这就像一个魅力，但我想通过 GUI 插入它。但它不会运行。结果出现以下错误：

  File "C:\Users\Luan\AppData\Local\Programs\Python\Python38-32\lib\copy.py", line 230, in _deepcopy_dict
    y[deepcopy(key, memo)] = deepcopy(value, memo)
  File "C:\Users\Luan\AppData\Local\Programs\Python\Python38-32\lib\copy.py", line 161, in deepcopy
    rv = reductor(4)
TypeError: cannot pickle '_tkinter.tkapp' object

这是整个代码，任何帮助将不胜感激。谢谢。

    print("First Name: %s\nLast Name: %s" % (givenurl.get(), givenplace.get()))

解决方案

您收到的错误是因为该条目是一个对象，您无法获取数据，因为您获取错误。尝试检索对象中的数据，它很可能是一本字典！

givenurl = tk.Entry(master)
givenplace = tk.Entry(master)

如果你想使用 givenurl，试试这个，

url_var = givenurl.get()
browser.get(url_var)
