s = requests.Session()
r = s.post('http://x.x.x.x/cgi/login.cgi', data={'name': 'ADMIN', 'pwd': 'ADMIN'},verify=False)
r = s.get(url, cookies=s.cookies,stream=True)
print(r.text)IP is the internal IP. Files can be downloaded using IE, Firefox and other browsers. I just use requests to access and report an error of 500. I really don’t know why. Please help!
The following is the code:
import requests
import ssl
from requests.packages.urllib3.exceptions import InsecureRequestWarning
requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
ssl._create_default_https_context = ssl._create_unverified_context
s = requests.Session()
requests.packages.urllib3.disable_warnings()
r=s.post('https://172.30.1.141/cgi/login.cgi', data={'name': 'ADMIN', 'pwd': 'ADMIN'},verify=False)
print(r.text)
url='https://172.30.1.141/cgi/url_redirect.cgi?url_name=ikvm&url_type=jwsk'
rr=s.get(url).content
print(rr)
The following is the information sent by the browser:

It turns out to be a header problem, just add 'Referer' and it will be fine
Post the entire code for analysis. Now it seems that you need to know all the information at the moment when the browser downloads the file before you can simulate it with python, or you can directly find the reason for the 500 error on the server side.
You need to use r.content to download the file. In addition, after the post login is successful, the cookie is already in s, so there is no need to pass parameters when getting it
