如何在python中使用带有代理身份验证的requests.post()? [英] how to use requests.post() with proxy authentication in python?

问题描述

from bs4 import BeautifulSoup
import requests
from requests.auth import HTTPProxyAuth

url = "http://www.transtats.bts.gov/Data_Elements.aspx?Data=2" 
proxies = {"http":"xxx.xxx.x.xxx: port"}
auth = HTTPProxyAuth("username", "password")
r = requests.get(url, proxies=proxies, auth=auth)
soup = BeautifulSoup(r.text,"html.parser") 
viewstate_element = soup.find(id = "__VIEWSTATE").attrs 
viewstate = viewstate_element["value"]
eventvalidation_element = soup.find(id="__EVENTVALIDATION").attrs
eventvalidation = eventvalidation_element["value"]


data =     {'AirportList':"BOS",'CarrierList':"VX",'Submit':'Submit',"__EVENTTARGET":"","__EVENTARGUMENT":"","__EVENTVALIDATION":eventvalidation,"}
r = requests.post(url, proxies, auth, data )
print r

当我使用requests.get(url, proxies=proxies, auth=auth)时，此代码可以正常工作，但是在代理身份验证下必须通过requests.post()发送某些数据时该怎么办?

This code works fine when I use requests.get(url, proxies=proxies, auth=auth), but what to do when there is some data that has to be sent through requests.post() under proxy authentication?

推荐答案

代表Vikas Neha Ojha，所有人都能看到

On behalf of Vikas Neha Ojha so all can see

proxies = {'http': 'http://username:password@ip:port', 'https': 'http://usernamepassword@ip:port'}

然后

requests.post(url, proxies=proxies, data=data)
