Python 读取/解析URL'；列表时发生http.client.RemoteDisconnected错误；s

我正在开发一个简单的url解析器：其思想是将url放在一列中，尝试解析它并打印出它重定向到的位置的输出

我的基本功能正常工作，但它偶尔抛出http.client.RemoteDisconnected异常，程序停止：抛出一些错误（如下）

---

解决：其实很简单：

添加

http.client.HTTPException

。在python2中是这样的

httplib.HTTPException作为e:

即

Traceback (most recent call last):
