网址库2.网址：<网址打开错误未知网址类型：webcal>尝试写入文件时.ics

Question

我正在尝试将网页(例如 https://careers.unc.edu/calendar(上的日历(.ics(的内容写入文件。以下是我的代码尝试：

def write_file(ics_url, set_calendar_name):
url = ics_url
response = urllib2.urlopen(url)
webContent = response.read()
f = open(set_calendar_name, 'w')
f.write(webContent)
f.close
print 'File saved as: ' + set_calendar_name
print
return set_calendar_name

但是，我不断收到以下错误：

Traceback (most recent call last):
File "get_calendar.py", line 99, in <module>
write_file(get_ics_url('https://careers.unc.edu/calendar'), 'carolina.ics')
File "get_calendar.py", line 36, in write_file
response = urllib2.urlopen(url)
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 154, in urlopen
return opener.open(url, data, timeout)
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 429, in open
response = self._open(req, data)
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 452, in _open
'unknown_open', req)
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 407, in _call_chain
result = func(*args)
File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/urllib2.py", line 1266, in unknown_open
raise URLError('unknown url type: %s' % type)
urllib2.URLError: <urlopen error unknown url type: webcal>

有没有人对我的代码中导致它的原因有任何想法？例如，当我使用以下 URL 运行时，我的程序运行良好：https://meded.hms.harvard.edu/calendar 但前面提到的那个则不然。

解决方案：我最终弄清楚出了什么问题。这

link.get('href')

包含

'webcal:'

而不是

'https:' 

一开始，所以我不得不更换它。固定代码应为：

if link.get('href') != None and '.ics' in link.get('href'):
endout = link.get('href')
if endout[:6] == 'webcal':
endout ='https' + endout[6:]
