这是我的代码，所有网址都是Config Parser格式文件。按下按钮时，文件将无法下载。出了什么问题？我用urllib应该使用urllib2吗？有些功能可能在那里，但不使用只是忽略它。

出了什么问题？我用urllib应该使用urllib2吗？
是。只需在您的代码中添加2即可修复此问题，这一事实显然证明了这一点，但它并没有解释清楚。
正如urllib.urlopen的文档所说：
从版本2.6开始不推荐使用：在Python 3中删除了
urlopen()函数，转而使用urllib2.urlopen()。
这并不意味着他们在2.6版本的urllib中停止修复错误（有一个错误修复，直到2.7.9），但这确实意味着永远不会添加缺少的功能。其中包括一些HTTP身份验证，重定向，使用非标准CA的HTTPS，代理设置和代理身份验证。
除了＆＃34之外什么都不知道问题;下载没有发生＆＃34;，或者您尝试下载的URL（您似乎传递了一个名为{的变量{1}}没有在任何地方分配，或者您正在运行的设置，无法确切地知道这些问题中的哪一个（或任何其他问题）是关键。
