[英]Error in Python Mechanize - “mechanize._mechanize.BrowserStateError: not viewing HTML”
for link in br.links(url_regex="inquiry-results.jsp"):
cb[link.url] = link
for page_link in cb.values():
for link in br.links(url_regex="inquiryDetail.jis"):
....................
url = link.absolute_url
br.follow_link(link)
......................
br.follow_link(page_link)
This is my code. 这是我的代码。 Basically, it extracts page links [Link of page 1,2,3,4,5...] and data links from particular page.
基本上,它提取页面链接[第1,2,3,4,5页的链接...]和特定页面的数据链接。 Then it goes in each data link and extracts some data and when done it moves to the next page.
然后它进入每个数据链接并提取一些数据,完成后移动到下一页。 But I always get this error:
但我总是得到这个错误:
Traceback (most recent call last):
File "C:\python27\test.py", line 95, in <module>
for link in br.links(url_regex="inquiryDetail.jis"):
File "build\bdist.win32\egg\mechanize\_mechanize.py", line 405, in links
mechanize._mechanize.BrowserStateError: not viewing HTML
Can anyone help? 有人可以帮忙吗?
Thanks to the link posted by loevborg, I've been using this: 感谢loevborg发布的链接,我一直在使用这个:
br.open('http://example.com')
br._factory.is_html = True
Now br.viewing_html()
will evaluate to True 现在
br.viewing_html()
将评估为True
This seems to be related to a check to see if the response is valid HTML: 这似乎与检查响应是否有效HTML有关:

Perhaps the response you get it XHTML, or has invalid headers? 也许你得到XHTML的响应,或者有无效的标题? There may be some way to override the
is_html
attribute (like here ). 可能有某种方法可以覆盖
is_html
属性(就像这里一样)。
在br.open可能帮助之前将您的应用程序作为浏览器引入:
br.addheaders = [('User-agent','Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/45.0.2454101')]
