（注：需要带上登录成功后的cookie发包）
一、分析目标：
点击进去爬取每个企业里面的电话、邮箱
（我们是来投简历的，切勿干非法的事情）
每个单位的URL记下来
（一定是在前一个页面能找到的，不然只能跳转进来是吧）
我们可以看到这个URL就是他跳转的URL
其实我们前面已经提前爬取了每个单位的这个URL
思路：
对我们爬取的URL发包，并对数据包进行处理，提取我们需要的数据
二、代码实现
目标1：对于捕获的URL内嵌发包
for u in [link]:
html2 = get_page(u)
soup2 = BeautifulSoup(html2, 'lxml')
email_phone_div = soup2.find('div', attrs={'class': 'index_detail__JSmQM'})目标2：找到电话和邮箱的位置
（1）找到他的上一级（也就是都包含他们的）
for u in [link]:
html2 = get_page(u)
soup2 = BeautifulSoup(html2, 'lxml')
email_phone_div = soup2.find('div', attrs={'class': 'index_detail__JSmQM'})目标3：提取电话和邮箱
（1）首先加一个if判空
把phone和email的上一级进行判空，不为空再继续
if email_phone_div is not None:
phone_div = email_phone_div.find('div', attrs={'class': 'index_first__3b_pm'})
email_div = email_phone_div.find('div', attrs={'class': 'index_second__rX915'})
#中间为提取email和phone代码
else:
phone = ''
email = ''
#遍历一遍就写入一个数据
csv_w.writerow((title.strip(), link, type_texts, money, email, phone))
（2）对phone进行提取
首先也是对上一级标签判空，不为空才继续
if phone_div is not None:
phone_element = phone_div.find('span', attrs={'class': 'link-hover-click'})
if phone_element is not None:
phone = phone_element.find('span',attrs={'class':'index_detail-tel__fgpsE'}).text
else:
phone = ''
else:
phone = ''（3）对email提取
和phone一样先对上一级判空，不为空再继续提取
if email_div is not None:
email_element = email_div.find('span', attrs={'class': 'index_detail-email__B_1Tq'})
if email_element is not None:
email = email_element.text
else:
email = ''
else:
email = ''（3）对内嵌请求处理的完整代码
for u in [link]:
html2 = get_page(u)
soup2 = BeautifulSoup(html2, 'lxml')
email_phone_div = soup2.find('div', attrs={'class': 'index_detail__JSmQM'})
if email_phone_div is not None:
phone_div = email_phone_div.find('div', attrs={'class': 'index_first__3b_pm'})
email_div = email_phone_div.find('div', attrs={'class': 'index_second__rX915'})
if phone_div is not None:
phone_element = phone_div.find('span', attrs={'class': 'link-hover-click'})
if phone_element is not None:
phone = phone_element.find('span',attrs={'class':'index_detail-tel__fgpsE'}).text
else:
phone = ''
else:
phone = ''
if email_div is not None:
email_element = email_div.find('span', attrs={'class': 'index_detail-email__B_1Tq'})
if email_element is not None:
email = email_element.text
else:
email = ''
else:
email = ''
else:
phone = ''
email = ''
csv_w.writerow((title.strip(), link, type_texts, money, email, phone))三、完整代码
