被动式扫描流量需要去重啊 about passivescanner

@aipengjie (⊙﹏⊙)，去重也是个大问题，但我想不出有什么好的方法来解决用来去重带来的资源消耗，比如单纯用set(hash)的方式的话。

@controller.handler
    def response(self, f):
        infos = getinfo.parse(f)
        host = urlparse.urlparse(infos['url']).netloc
        if self.host != host and self.host != '*':
            return
        result = filterer.filterer(infos)
        if result['unique'] not in url_lists and result['unique']:
            url_lists.add(result['unique'])
            q.put(infos)


tlag = "***"
re_rule = "(?P<param>[^&?]+\=(?P<value>[^&$]*))"
suffixs = [
    ".jpg", ".gif", ".png", ".js", ".xlsx", ".apk", ".flv", ".css",
    ".swf", '.xml', '.avi', '.zip', '.pdf', '.rar', '.doc', '.xls'
]


def filterer(infos):
    result = {}
    try:
        url = infos['url']
        data = infos['data']
        new_url = url + '?' + data if data else url.split('#')[0]
        flag = filter(lambda x: url.endswith(x), suffixs)
        if flag:
            u = ""
        elif '?' in new_url:
            u = re.sub(common_rule, tlag, new_url)
        else:
            u = hashlib.md5(new_url).hexdigest()
        result['url'] = url
        result['unique'] = u
    except:
        traceback.print_exc()
    finally:
        return result

这是很早写的去重代码 可以参考一下
