我想打开一个名为statseeker的报告工具的内部网页的网页，该工具存储从打开URL时运行的报告生成的图像。到目前为止，我在这：
import urllib
import urllib2
urlauth = 'http://statseeker/cgi/nim-report-lastn-drilldown?mode=ping&tz=America/Chicago&last_n=24h&device=jc-2090-1'
realm = 'statseeker'
username = 'admin'
password = '*******'
auth_handler = urllib2.HTTPBasicAuthHandler()
auth_handler.add_password(realm, urlauth, username, password)
opener = urllib2.build_opener(auth_handler)
data = opener.open(urlauth).read()
print data
此代码成功访问网页并在页面末尾两侧生成图形为.PNG图像，输出如下：
>>> import urllib
>>> import urllib2
>>>
>>> urlauth = 'http://statseeker/cgi/nim-report-lastn-drilldown?mode=ping&tz=Ame
rica/Chicago&last_n=24h&device=jc-2090-1'
>>> realm = 'statseeker'
>>> username = 'admin'
>>> password = '******'
>>> auth_handler = urllib2.HTTPBasicAuthHandler()
>>> auth_handler.add_password(realm, urlauth, username, password)
>>> opener = urllib2.build_opener(auth_handler)
>>> data = opener.open(urlauth).read()
>>> print data

我不确定如何保存这些图像。最后的文件名每秒都会改变。
我希望能够在页面上保存我选择其名称的任何文件，直到通配符部分。
这样的前提是：
/graphs/ping.jc-2090-1.rtt.24h.1%%%%%%%%.png的所有图片。save在这个新文件位置选择，我选择的名称。image class=graph部分？任何想法？
关注：
/graphs/ping.jc-2090-1.rtt.24h。%%%%%%%%%。PNG /graphs/ping.jc-2090-1.lost.24h。%%%%%%%%%。PNG
一旦确定了所有我没有多少剩下的，然后制作漂亮的HTML网站来显示这些图像。
答案 0 :(得分：0)
使用lxml或BeutifulSoup来解析该页面，并轻松访问页面上的HTML标记。
我无法测试它，但它可能是这样的。
data =您的HTML字符串
import lxml, lxml.html
html = lxml.html.fromstring( data )
imgs = html.cssselect('img.graph')
for x in imgs:
print 'http://statseeker%s' % ( x.attrib['src'] )
这应该将网址打印到文件。
现在，您可以使用您的代码逐个获取此文件，然后将新data保存在本地文件中。
修改
# get all urls
imgs_urls = []
for x in imgs:
imgs_urls.append( 'http://statseeker%s' % (x.attrib['src']) )
# print all urls
for url in imgs_urls:
print url
