基本上,我创建了一个非常混乱的代码来从 bing 搜索查询中获取链接。我面临的问题是我收到了太多与 bing 相关的链接。

我已经尝试使用此当前代码来删除这些,但我更喜欢黑名单。

这是我的代码:

import re, urllib
class MyOpener(urllib.FancyURLopener):
    version = 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.15) Gecko/20110303 Firefox/3.6.15'
myopener = MyOpener()
dork = raw_input("Dork:")
pagevar = ['1','11','23','34','45','46','47','58','69']
for page in pagevar:
    bingdork = "http://www.bing.com/search?q=" + str(dork) + "&first=" + str(page)
    bingdork.replace(" ", "+")
    links = re.findall('''href=["'](.[^"']+)["']''', myopener.open(bingdork).read(), re.I)
    toremove = []
    for i in links:
        if "bing.com" in i:
            toremove.append(i)
        elif "wlflag.ico" in i:
            toremove.append(i)
        elif "/account/web?sh=" in i:
            toremove.append(i)
        elif "/?FORM" in i:
            toremove.append(i)
        elif "javascript:void(0);" in i:
            toremove.append(i)
        elif "javascript:" in i:
            toremove.append(i)
        elif "go.microsoft.com/fwlink" in i:
            toremove.append(i)
        elif "g.msn.com" in i:
            toremove.append(i)
        elif "onlinehelp.microsoft.com" in i:
            toremove.append(i)
        elif "feedback.discoverbing.com" in i:
            toremove.append(i)
        elif "/account/web?sh=" in i:
            toremove.append(i)
        elif "/?scope=web" in i:
            toremove.append(i)
        elif "/explore?q=" in i:
            toremove.append(i)
        elif "https://feedback.discoverbing.com" in i:
            toremove.append(i)
        elif "/images/" in i:
            toremove.append(i)
        elif "/videos/" in i:
            toremove.append(i)
        elif "/maps/" in i:
            toremove.append(i)
        elif "/news/" in i:
            toremove.append(i)
            for i in toremove:
                links.remove(i)
                for i in links:
                    print i

假设我输入:Dork:cfm id

我会得到的结果是:

我想要的结果是:

http://pastebin.com/Xi28BzXs

我想删除以下内容:

/search?q=cfm+id&lf=1&qpvt=cfm+id
/account/web?sh=5&ru=%2fsearch%3fq%3dcfm%2520id%26first%3d69&qpvt=cfm+id
/search?q=cfm+id&rf=1&qpvt=cfm+id
/search?q=cfm+id&first=69&format=rss
/search?q=cfm+id&first=69&format=rss
/?FORM=Z9FD1
javascript:void(0);
/account/general?ru=http%3a%2f%2fwww.bing.com%2fsearch%3fq%3dcfm+id%26first%3d69&FORM=SEFD
/?scope=web&FORM=HDRSC1
/images/search?q=cfm+id&FORM=HDRSC2
/videos/search?q=cfm+id&FORM=HDRSC3

基本上,我需要一个过滤器,它允许我只从 bing 中获取 VALID 链接,并从 bings 端删除所有废话。

非常感谢, BK PS 对不起,如果我的解释不好。

您是否尝试过使用 beautifulsoup、lxml 或 html5lib(首选 lxml.etree)进行 css/xpath 查询的 html 解析路由,伪代码:

html = htmlparse.parse(open(url))
hrefs = []

for a in html.xpath('//a'):
    if a['href'].startswith('http://') or a['href'].startswith('https://'):
       hrefs.append(a['href'])

当然这是伪代码,你应该适应你是否使用beautifulsouplxmlhtml5lib

如果您正在寻找的更像是根据白名单清理/清理页面 html,您可能会喜欢使用CleanText,可以进一步自定义该程序以使用正则表达式过滤属性,但这留作练习;)
