问题描述
我收到了一个网址:https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp®-75-desktop-virtualization-solutions;它来自 BeautifulSoup.
url=u'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp\xae-75-desktop-virtualization-solutions'
我想再次反馈到urllib2.urlopen.
导入 urllib2源 = urllib2.urlopen(url).read()
我得到的错误:
UnicodeEncodeError: 'gbk' codec can't encode character u'\xae' in position 43: 非法多字节序列
因此,我尝试了:
source = urllib2.urlopen(url.encode("utf-8")).read()
它得到了页面源,但它与原始url的不同.
originalUrl = 'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp®-75-desktop-virtualization-solutions'originalSource = urllib2.urlopen(originalUrl).read()原始来源 == 来源
结果为假.有没有办法修复这个网址?如何将 u'\xae' 转换为原始的 ®
?
URL 必须是有效的字节串,并且非 ASCII 代码点编码正确.您需要编码为 UTF-8,然后 url 引用您的 URL 路径:
导入urllib导入 urllib2导入 urlparseoriginalUrl = u'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp\xae-75-desktop-virtualization-solutions'parsed_link = urlparse.urlsplit(originalUrl.encode('utf8'))parsed_link = parsed_link._replace(path=urllib.quote(parsed_link.path))encoding_link = parsed_link.geturl()源 = urllib2.urlopen(encoded_link).read()
演示:
>>>导入 urllib>>>导入 urllib2>>>导入 urlparse>>>originalUrl = u'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp\xae-75-desktop-virtualization-solutions'>>>parsed_link = urlparse.urlsplit(originalUrl.encode('utf8'))>>>parsed_link = parsed_link._replace(path=urllib.quote(parsed_link.path))>>>encoding_link = parsed_link.geturl()>>>编码链接'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp%C2%AE-75-desktop-virtualization-solutions'>>>源 = urllib2.urlopen(encoded_link).read()>>>len(来源)68758I received a url: https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp®-75-desktop-virtualization-solutions; it is from BeautifulSoup.
url=u'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp\xae-75-desktop-virtualization-solutions'
I want to feed back into urllib2.urlopen again.
import urllib2
source = urllib2.urlopen(url).read()
The error I get:
UnicodeEncodeError: 'gbk' codec can't encode character u'\xae' in position 43: illegal multibyte sequence
Thus, I tried:
source = urllib2.urlopen(url.encode("utf-8")).read()
It got page source, however it is different from what from the original url.
originalUrl = 'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp®-75-desktop-virtualization-solutions'
originalSource = urllib2.urlopen(originalUrl).read()
originalSource == source
The result is False. Is there any idea to fix this url? How to convert u'\xae' into original ®
?
URLs must be valid bytestring, with non-ASCII codepoints encoded correctly. You'll need to encode to UTF-8, then url quote the path of your URL:
import urllib
import urllib2
import urlparse
originalUrl = u'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp\xae-75-desktop-virtualization-solutions'
parsed_link = urlparse.urlsplit(originalUrl.encode('utf8'))
parsed_link = parsed_link._replace(path=urllib.quote(parsed_link.path))
encoded_link = parsed_link.geturl()
source = urllib2.urlopen(encoded_link).read()
Demo:
>>> import urllib
>>> import urllib2
>>> import urlparse
>>> originalUrl = u'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp\xae-75-desktop-virtualization-solutions'
>>> parsed_link = urlparse.urlsplit(originalUrl.encode('utf8'))
>>> parsed_link = parsed_link._replace(path=urllib.quote(parsed_link.path))
>>> encoded_link = parsed_link.geturl()
>>> encoded_link
'https://www.packtpub.com/virtualization-and-cloud/citrix-xenapp%C2%AE-75-desktop-virtualization-solutions'
>>> source = urllib2.urlopen(encoded_link).read()
>>> len(source)
68758
