写段代码看看别人都怎么称呼你网站的？

步骤很简单：
1）使用google的搜索inlink的语法link:url和num参数指定一页显示的结果数，
在这个结果中找到外链的页面url，排除网站内链接。

def search_inlinks_from_google(query,result_num)
        escaped_query = CGI.escape("link:#{query}")
        google_url = "http://www.google.com/search?q=#{escaped_query}&num=#{result_num}"
        inlinks = []
       
        Nokogiri::HTML(open(google_url,:proxy => rand_proxy)).css('h3.r > a.l').each do |node|
            link = node.attributes['href']
            inlinks << link if not self_inlink?(query,link)
            puts "inlink: #{link}"
        end
        return inlinks
    end

2)依次fetch每个url的页面，在fetch下来的页面找到目标链接，把achor
text记录下来，并计数。

 def find_site_names_by_inlinks(inlinks,site_query)
        name_count_map = Hash.new{|hash,key| hash[key] = 0}
        inlinks.each do |link|
            puts "searching from #{link}..."
            Nokogiri::HTML(open(link,fetch_options)).xpath("//a").each do |link_node|
                name_count_map[link_node.text.strip.downcase] += 1 if link_node.attributes["href"].to_s =~ /#{site_query}/
            end
        end
        p name_count_map
        name_count_map.sort{|a,b| b[1] <=> a[1]}.collect{|name,count| name }
    end

3）按照出现次数排序，比较靠前的基本是这个网站的名字了。
我们使用了好几个代理，每次随机选取一个，以防被封掉。

        p name_count_map
