1. 爬虫前奏
明确目的，例如，爬取直播网站“某猫”英雄联盟版块主播名字和人气。找到数据对应的网页，分析网页的结构找到数据所在标签位置。
2. 具体方法
模拟HTTP请求，向服务器发送请求，获取到服务器返回给我们的HTML，用正则表达式提取需要的数据。
3. 代码示例
完整代码如下，50行代码搞定python原生爬虫。
import re #正则表达式模块from urllib import request #通过request对象获取html页面class Spider():url = 'https://www.panda.tv/cate/lol'root_pattern = '<div class="video-info">([\s\S]*?)</div>' #()表示只提取定位标签中间内容name_pattern = '</i>([\s\S]*?)</span>'number_pattern = '<span class="video-number">([\s\S]*?)</span>'def __fetch_content(self): #私有方法，获取html页面r = request.urlopen(Spider.url) #在实例方法里读取类变量urlhtmls = r.read() #字节码htmls = str(htmls,encoding = 'utf-8') #将字节码转为字符串print(htmls)return htmlsdef __analysis(self,htmls):#分析htmls文本，通过正则表达式提取html文本中的主播名和人气值root_html = re.findall(Spider.root_pattern,htmls)anchors = []for html in root_html:name = re.findall(Spider.name_pattern,html)number = re.findall(Spider.number_pattern,html)anchor = {'name':name,'number':number}anchors.append(anchor)print(anchors)return anchorsdef __refine(self,anchors): #精炼数据，剔除文本中的空格和换行符等内容，规范成易读的数据targets = []for target_list in anchors:name = target_list['name'][0].strip()number = target_list['number'][0]one_people = {'name':name,'number':number}targets.append(one_people)print(targets); return targetsdef __sort(self,anchors): #对精炼后的数据按主播人气值进行排序anchors = sorted(anchors,key = self.__sort_seed,reverse = True)return anchorsdef __sort_seed(self,anchor):#设置排序规则r = re.findall('\d*',anchor['number'])number = float(r[0])if '万' in anchor['number']:number *= 10000return numberdef __show(self,anchors): #展示最终爬取的数据for rank in range(0,len(anchors)):print('rank ' + str(rank+1)+ ':' +anchors[rank]['name'] + ' ' + anchors[rank]['number'])def go(self): #公开方法，go方法是Spider的入口方法htmls = self.__fetch_content()anchors = self.__analysis(htmls)anchors = self.__refine(anchors)anchors = self.__sort(anchors)self.__show(anchors)spider = Spider()spider.go()
以下是print()到控制台的数据：

以上数据是11月30号下午6点爬取的，因为直播网站的特点，不同时间段爬取的数据差异较大。另外，除了panda直播LOL板块，其他板块的数据也可以用上面的方法爬取，只需要将url最后的lol换成其他板块的名字即可。但是想要爬取其他直播网站的数据，上面的代码就需要改动其他地方了，因为不同直播网站的html结构是不一样的，需要具体分析html页面，写出相应的正则表达式以提取想要的数据。
写在最后，有爬虫，自然会有反爬虫，我试着爬过“某鱼”的数据，发现并不能通过request对象获取html网页，所以，需要学习的东西还很多，加油吧。
