（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))
