未通过get请求接收html内容

Question

我需要搜集这个website上所有可用的数据

这是我的密码

import requests

url = "https://bpcleproc.in/EPROC/viewtender/13474"

r = requests.get(url)

print(r)
print(r.text) 

我得到的结果是

<Response [200]>
<script type="text/javascript">
window.location.href = "/EPROC/viewtender/13474";
</script>

我不明白为什么这样不行。网站是通过js文件生成的吗

Answer 1

网站会在重定向循环中设置一堆cookies，然后再将您带到最终页面，原因如下：

$ curl -vv https://bpcleproc.in/EPROC/viewtender/13474

您可以使用requests.Session来模拟该行为：

import requests

session = requests.Session()

# First, get the cookies.
# The session keeps track of cookies and requests follows redirects for you
r = session.get("https://bpcleproc.in/EPROC/viewtender/13474")

# Then, simulate following the JS redirect
r = session.get("https://bpcleproc.in/EPROC/viewtender/13474")

print(r)
print(r.text)
