为什么80%的码农都做不了架构师？>>>

记录下自己实现阿里巴巴关键词排名查询的主要代码及pyquery、urllib库的基础用法

urllib 基础模块的应用，通过该类获取到url中的html文档信息，内部可以重写代理的获取方法

class ProxyScrapy(object): def init(self): self.proxy_robot = ProxyRobot() self.current_proxy = None self.cookie = cookielib.CookieJar()

def __builder_proxy_cookie_opener(self):
cookie_handler = urllib2.HTTPCookieProcessor(self.cookie)
handlers = [cookie_handler]

 if PROXY_ENABLE:
     self.current_proxy = ip_port = self.proxy_robot.get_random_proxy()
     proxy_handler = urllib2.ProxyHandler({'http': ip_port[7:]})
     handlers.append(proxy_handler)

 opener = urllib2.build_opener(*handlers)
 urllib2.install_opener(opener)
 return opener

def get_html_body(self,url): opener = self.__builder_proxy_cookie_opener()

 request=urllib2.Request(url)
 #request.add_header("Accept-Encoding", "gzip,deflate,sdch")
 #request.add_header("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
 #request.add_header("Cache-Control", "no-cache")
 #request.add_header("Connection", "keep-alive")

 try:
     response = opener.open(request,timeout=2)

     http_code = response.getcode()
     if http_code == 200:
         if PROXY_ENABLE:
             self.proxy_robot.handle_success_proxy(self.current_proxy)
         html = response.read()
         return html
     else:
         if PROXY_ENABLE:
             self.proxy_robot.handle_double_proxy(self.current_proxy)
         return self.get_html_body(url)
 except Exception as inst:
     print inst,self.current_proxy
     self.proxy_robot.handle_double_proxy(self.current_proxy)
     return self.get_html_body(url)

[代码]根据输入的公司名及关键词列表，返回每个关键词的排名

def search_keywords_rank(keyword_company_name, keywords): def get_context(url): start=clock() html=curl.get_html_body(url) finish=clock() print url,(finish-start)

 d = pq(html)
 items = d("#J-items-content .ls-item")
 items_c = len(items)
 print items_c
 if items_c < 38:
     return get_context(url)
 return items, items_c

result = OrderedDict() for keyword in keywords: for page_index in range(1,9): u = url % (re.sub('\s+', '_', keyword.strip()), page_index) items, items_c = get_context(u) b = False for item_index in range(0, items_c): e=items.eq(item_index).find('.title a') p_title = e.text() p_url = e.attr('href')

         e=items.eq(item_index).find('.cright h3 .dot-product')
         company_name = e.text()
         company_url = e.attr('href')

         if  keyword_company_name in company_url:
             total_index = (page_index-1)*38 +item_index+1+(0 if page_index==1 else 5)
             print 'page %s, index %s, total index %s' % (page_index, item_index+1, total_index)
             b = True
             if keyword not in result:
                 result[keyword] = (p_title, p_url, page_index, item_index+1, total_index, u)
             break
     if b:
         break

return result

由于想放在web服务器上面，这个web页面实际上是用tonardo做的，在php和tonado同用一个端口的话又用了nginx做前端代理服务器，对nginx的设置也是这次应用的一个学习点吧 ;)
