在 Python 中抓取 asp 页面时'/'应用程序中出现服务器错误

Question

我的代码：

import requests
import os
import cookielib
from bs4 import BeautifulSoup

url = 'http://www.bseindia.com/corporates/Insider_Trading.aspx'
jar = cookielib.CookieJar()
r = requests.get(url, cookies=jar)

soup = BeautifulSoup(r.content)
view_state = soup.find(id ="__VIEWSTATE")


headers = {"User-Agent": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0","Accept":"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8","Referer":"http://www.bseindia.com/corporates/Insider_Trading.aspx"}
payload = {"__EVENTTARGET": "ctl00$ContentPlaceHolder1$lnkDownload", "__EVENTARGUMENT": "","__VIEWSTATE":view_state,"__EVENTVALIDATION":"g8vXAQKJsYefCgK6rpDlDwL8np6XAwLl44LQAgK0w8TlCwKHlNXODQKW0sv1BgLei4rQAwKExL/8BQLJsJHgCQLhsb3hCQLJsLmaCAL40JWiCgK9vIn8DA==",
"myDestination1":"#","WINDOW_NAMER":"1","myDestination":"#","ctl00$ContentPlaceHolder1$fmdate":"20131003","ctl00$ContentPlaceHolder1$eddate":"20131009",
"ctl00$ContentPlaceHolder1$hdnCode":"","ctl00$ContentPlaceHolder1$txtDate":"","ctl00$ContentPlaceHolder1$txtTodate":"","ctl00$ContentPlaceHolder1$GetQuote1$hdnCode":"",
"ctl00$ContentPlaceHolder1$GetQuote1$smartSearch":"","ctl00$ContentPlaceHolder1$ddlregulation":"ALL"}
r = requests.post(url,cookies=jar,headers=headers,data=payload)
print r.content

我正在尝试做的是从上面的 url 下载一个 csv 文件，但出现问题中提到的错误。

我哪里出错了？

Answer 1

我相信

你的要求没有错。我尝试了您的代码并得到了相同的错误。

您看到的错误是用 ASP 编写的服务的常见错误。这几乎总是意味着服务器端存在配置问题。谷歌错误，您将看到许多可能的解决方案的点击，这些都不适合您，因为您不拥有该服务。

您确定您有正确的基本 URL 吗？是否有印度疯牛病服务使用情况的示例？
