我正在尝试从网站上抓取 csrf 令牌。但是,即使页面源中的令牌可用,我创建的脚本也会失败。这是site url。
我尝试过:
import requests
from bs4 import BeautifulSoup
url = 'https://fanniemae.mbs-securities.com/fannie/search?issrSpclSecuType=Super&status=Active'
with requests.Session() as s:
s.headers['User-Agent'] = 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.104 Safari/537.36'
r = s.get(url)
soup = BeautifulSoup(r.text,"lxml")
csrf = soup.select_one("[name='_csrf']").get("content")
print(csrf)

如何使用请求从该站点抓取 csrf 令牌?
答案 0 :(得分:0)
这里的技巧是在标头中包含 Accept
键和值以获得所需的响应。这就是我使用请求从该站点获取表格内容的方式:
import requests
from bs4 import BeautifulSoup
url = 'https://fanniemae.mbs-securities.com/fannie/search?issrSpclSecuType=Super&status=Active'
link = 'https://fanniemae.mbs-securities.com/api/search/fannie'
params = {
'issrSpclSecuType': 'Super',
'status': 'Active',
'page': 1,
'max_results': 100,
'sortField': 'cusip',
'sortAsc': 'true'
}
with requests.Session() as s:
s.headers['User-Agent'] = 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.104 Safari/537.36'
s.headers['Accept'] = 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9'
r = s.get(url)
soup = BeautifulSoup(r.text,"lxml")
s.headers['x-csrf-token'] = soup.select_one("[name='_csrf']")["content"]
s.headers['referer'] = 'https://fanniemae.mbs-securities.com/fannie/search?issrSpclSecuType=Super&status=Active'
res = s.get(link,params=params)
for item in res.json():
print(item['cusip'])
