我为什么不能在“请求”中循环通过“有效载荷”来迭代我的网页抓取？
作者：互联网
摘要：我想遍历请求有效负载,以便可以更改每个刮板的登录ID号.
我正在使用请求&美丽的汤做网刮.
要登录该页面,我需要输入唯一的ID号；我有一个这样的数字列表,称为hit_list.
对于任何给定的ID号,此脚本都可以正常工作.但是我想做的是自动化它,使其贯穿我的整个hit_list
换句话说,我希望payload_1中的num每次迭代都更改.目前num保持不变,并且抓取只是根据hit_list的长度进行迭代(即,在这种情况下,相同的抓取将运行五次)
请注意,我对编码非常陌生,这是我的第一个项目.我知道它可能存在问题,很高兴收到建设性的批评.

解决方法:
您需要为每个帖子获取新的__EVENTVALIDATION令牌等,您不能仅从浏览器中复制值并将其硬编码到帖子数据中：
import requests
url = 'https://ndber.seai.ie/pass/ber/search.aspx'
hit_list = [100100403, 100100965, 100101047, 100100874, 100100783]
h = {}
def renew(s):
soup = BeautifulSoup(s.get(url).content,"html.parser.)
return {"__VIEWSTATE": soup.select_one("#__VIEWSTATE")["value"],
"__VIEWSTATEGENERATOR": soup.select_one("#__VIEWSTATEGENERATOR")["value"],
"__EVENTVALIDATION": soup.select_one("#__EVENTVALIDATION")["value"]}
with requests.session() as s:
for num in hit_list:
payload_1 = {
'ctl00$DefaultContent$BERSearch$dfSearch$txtBERNumber': num,
'ctl00$DefaultContent$BERSearch$dfSearch$Bottomsearch': 'Search'}
# update the post data with new token values
payload_1.update(renew(s))
r = s.post(url, data=payload_1)
# scrape the page
soup = BeautifulSoup(r.content, 'html.parser')
如果我们运行代码并解析返回的内容,则可以看到我们正确获取了每个页面：

这为您提供了表格栏中BER证书号的所有信息,您已经有了BER证书号,因此您无需担心.
如您所知,您只需要将数据从第一篇文章返回的内容传递到第二个有效内容,如果将逻辑封装在函数中,这也将使您的代码更易于管理：
