PayPal招聘官网
首先,查看PayPal求职官网的结构,所发布的职位以列表的形式展示,点击列表里的职位,就可以跳转到对应的详情页。同时,某些国家和地区的职位比较多,分成了多页显示,则URL会以相应的页面编号来区分,例如https://jobsearch.paypal-corp.com/en-US/search?facetcitystate=san%20jose,ca&pagenumber=2
。因此判断大致需要如下几步即可抓取到每个职位的详情:
定位职位列表,找到每个职位对应的URL
遍历所有页面,重复完成上述操作,存储所有职位URL
通过职位的URL,访问职位描述,定位详情所在的位置,并保存职位描述

# 创建一个存储结果的dataframe df = pd.DataFrame(columns=['Title','Link']) # 创建URL的模板,添加不同的页码就可匹配不同的页面 job_url_header = 'https://jobsearch.paypal-corp.com/en-US/search?facetcountry=cn&facetcity=shanghai&pagenumber=' # 遍历所有页面,并存储结果 for i in range(2): job_url = job_url_header + str(i+1) print('URL: {}'.format(job_url)) job_html = url_request(job_url) # 将每个页面的结果存起来 df = df.append(job_parser(job_html))
