先上效果图吧,no pic say bird!
古人云: 心腹知彼,百战不殆. 好好去理解一下妹子们的内心想法,早日脱单!
这次我在一个某有名婚恋网站,抓取了一些数据,对她们的内心读白进行剖析.

我这次筛选条件: 女性,年事20-30,学通书科 ,就这些条件.
3000条妹子内心读白词云如下:
放心好了,她们都是追求精神知足而非物质,大部分都是要找生命中的另一半,那她们的另一半会是你吗?

天生词云的代码之前的文章里面有,这里就不展示了,自行前往查阅!
一个高效获取数据的办法.由于并没有什么仿照的操作,统统都可以人工来掌握,以是也不须要打开网页就能获取数据!
但我们须要剖析这个网页,打开网页 http://www.lovewzly.com/jiaoyou.html 后,按F12,进入Network项中
url在筛选条件后,只有page在发生变革,而且是一页页的累加,而且我们把这个url在浏览器中打开,会得到一批json字符串,以是我可以直接操作这里面的json数据,然后进行存储即可!
代码构造图:
操作流程:
headers 一定要构建反盗链以及仿照浏览器操作,先这样写,可以避免后续问题!
条件拼装
然后记得数据转json格式
然后对json数据进行提取,
把提取到的数据放到文件或者存储起来
紧张学习到的技能:
学习requests+urllib操作execl文件操作字符串非常处理其余其它根本要求数据
def craw_data(self): '''数据抓取''' headers = { 'Referer': 'http://www.lovewzly.com/jiaoyou.html', 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.104 Safari/537.36 Core/1.53.4620.400 QQBrowser/9.7.13014.400' } page = 1 while True: query_data = { 'page':page, 'gender':self.gender, 'starage':self.stargage, 'endage':self.endgage, 'stratheight':self.startheight, 'endheight':self.endheight, 'marry':self.marry, 'salary':self.salary, } url = 'http://www.lovewzly.com/api/user/pc/list/search?'+urllib.urlencode(query_data) print url req = urllib2.Request(url, headers=headers) response = urllib2.urlopen(req).read() # print response self.parse_data(response) page += 1
字段提取
def parse_data(self,response): '''数据解析''' persons = json.loads(response).get('data').get('list') if persons is None: print '数据已经要求完毕' return for person in persons: nick = person.get('username') gender = person.get('gender') age = 2018 - int(person.get('birthdayyear')) address = person.get('city') heart = person.get('monolog') height = person.get('height') img_url = person.get('avatar') education = person.get('education') print nick,age,height,address,heart,education self.store_info(nick,age,height,address,heart,education,img_url) self.store_info_execl(nick,age,height,address,heart,education,img_url)
文件存放
def store_info(self, nick,age,height,address,heart,education,img_url): ''' 存照片,与他们的内心独白 ''' if age < 22: tag = '22岁以下' elif 22 <= age < 28: tag = '22-28岁' elif 28 <= age < 32: tag = '28-32岁' elif 32 <= age: tag = '32岁以上' filename = u'{}岁_身高{}_学历{}_{}_{}.jpg'.format(age,height,education, address, nick) try: # 补全文件目录 image_path = u'E:/store/pic/{}'.format(tag) # 判断文件夹是否存在。 if not os.path.exists(image_path): os.makedirs(image_path) print image_path + ' 创建成功' # 把稳这里是写入图片,要用二进制格式写入。 with open(image_path + '/' + filename, 'wb') as f: f.write(urllib.urlopen(img_url).read()) txt_path = u'E:/store/txt' txt_name = u'内心独白.txt' # 判断文件夹是否存在。 if not os.path.exists(txt_path): os.makedirs(txt_path) print txt_path + ' 创建成功' # 写入txt文本 with open(txt_path + '/' + txt_name, 'a') as f: f.write(heart) except Exception as e: e.message
execl操作
def store_info_execl(self,nick,age,height,address,heart,education,img_url): person = [] person.append(self.count) #恰好是数据条 person.append(nick) person.append(u'女' if self.gender == 2 else u'男') person.append(age) person.append(height) person.append(address) person.append(education) person.append(heart) person.append(img_url) for j in range(len(person)): self.sheetInfo.write(self.count, j, person[j]) self.f.save(u'我主良缘.xlsx') self.count += 1 print '插入了{}条数据'.format(self.count)
