我正在学习机械师。我正在尝试打开一个文本文件,你点击的链接说明了 文字(.prn) 我遇到的一个问题是此页面上只有一个表单,文件不在表单中。 另一个问题是我在这个页面上有几个文本文件,但它们都有相同的名称 文字(.prn)。所以我想我需要到第一个打开它。使我试图打开的文本文件唯一的一件事就是它似乎被命名为
我所在的网页是: http://www.treasurydirect.gov/govt/reports/pd/mspd/2013/2013_feb.htm
这里是html的部分,我想在机械化中打开文本文件:
</div>

这是我的代码到目前为止从文本文件所在的页面开始:
br = mechanize.Browser()
br.set_handle_equiv(False)
br.open(site)
print 'br.title',br.title()
allforms = list(br.forms())
br.form = allforms[0]
br.follow_link(text_regex="February", nr=0)
#br.click_link(text='February', nr=0) # this works to
#next page
print br.title()
allforms = list(br.forms())
print allforms
br.form = allforms[0]
getstuff=br.click_link(text="Text (.prn)", nr=0) # this works to
csvData=getstuff.readlines() # this is where is get error
这是我的追溯:
Traceback (most recent call last):
File "treasury2.py", line 56, in <module>
csvData=getstuff.readlines()
File "C:\Python27\lib\site-packages\mechanize\_urllib2_fork.py", line 173, in __getattr__
raise AttributeError, attr
AttributeError: readlines
我正在使用mechanize,BeautifulSoup,urllib,urllib2和python27
请给我一些帮助,甚至暗示你认为我应该使用什么。
答案 0 :(得分:1)
在getstuff=br.click_link(text="Text (.prn)", nr=0)
之后,而不是你的 csvData = getstuff.readlines(),你应该致电:
br.open(getstuff)
csvData = br.response().read()
如果您需要对上一页执行任何其他操作(例如 2013_feb.htm ),请致电:
br.back()
会使br
回到br.open
之前的相同状态。
