用请求传递数据modu

Question

我正试图向我的大学网页请求检索我的成绩。 有我成绩的页面需要先登录“http://www4.uva.br/UniversusNet/Seguro/Login.aspx?ReturnUrl=%2fUniversusNet%2fNotasFaltasTotais.aspx” 这一页把我引向年级。你知道吗

我想在我制作的应用程序上打印我的成绩。 到目前为止，我做了这个代码来打印页面，但是当我执行时返回的是错误407：代理身份验证 我想知道我现在错过了什么。。。。你知道吗

from requests import *

    }

with session() as sesh:

    LOGINURL = 'http://www4.uva.br/UniversusNet/Seguro/Login.aspx?ReturnUrl=%2fUniversusNet%2fNotasFaltasTotais.aspx'
    sesh.get(LOGINURL,proxies={"http":"xxxxxxx:xxxx"},auth=("xxxxxxx","xxxxxxxx")) #Get request to get the session ID cookie
##    sessionID = sesh.cookies['ASP.NET_SessionId'] #Grab session ID value
##    sessionIDname = 'ASP.NET_SessionId='
##    sessionIDheader = str(sessionIDname + sessionID) #Prepare session ID header
##    requestheaders['Cookie'] = sessionIDheader # Add session ID header to requestheaders dictionary


    response = sesh.post('http://www4.uva.br/UniversusNet/Seguro/Login.aspx?ReturnUrl=%2fUniversusNet%2fNotasFaltasTotais.aspx', data=payload,  headers=requestheaders)

    print(response.headers)
    print(response.content)

Answer 1

尝试直接将代理信息设置到会话（类似于：

from requests.auth import HTTPProxyAuth


sesh.proxies = {
    "http": "http://www4.uva.br:8080",  # MAKE SURE THE DATA IS CORRECT !!!
}
sesh.auth = HTTPProxyAuth("user", "pwd")

sesh.get(LOGINURL)
