urllib2.HTTPError:HTTP错误403:禁止

Question

我正在尝试使用python自动下载历史股票数据.我尝试打开的URL以CSV文件响应,但我无法使用urllib2打开.我之前在几个问题中已经尝试更改用户代理,我甚至尝试接受响应cookie,没有运气.你能帮忙吗？

注意:同样的方法适用于雅虎财经.

码:

import urllib2,cookielib

site= "http://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/getHistoricalData.jsp?symbol=JPASSOCIAT&fromDate=1-JAN-2012&toDate=1-AUG-2012&datePeriod=unselected&hiddDwnld=true"

hdr = {'User-Agent':'Mozilla/5.0'}

req = urllib2.Request(site,headers=hdr)

page = urllib2.urlopen(req)

错误

文件"C:\ Python27\lib\urllib2.py",第527行,在http_error_default中引发HTTPError(req.get_full_url(),代码,msg,hdrs,fp)urllib2.HTTPError:HTTP错误403:禁止

谢谢你的协助

Answer 1

通过添加更多标题,我能够获取数据:

import urllib2,cookielib

site= "http://www.nseindia.com/live_market/dynaContent/live_watch/get_quote/getHistoricalData.jsp?symbol=JPASSOCIAT&fromDate=1-JAN-2012&toDate=1-AUG-2012&datePeriod=unselected&hiddDwnld=true"
hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
       'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
       'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
       'Accept-Encoding': 'none',
       'Accept-Language': 'en-US,en;q=0.8',
       'Connection': 'keep-alive'}

req = urllib2.Request(site, headers=hdr)

try:
    page = urllib2.urlopen(req)
except urllib2.HTTPError, e:
    print e.fp.read()

content = page.read()
print content

实际上,它只适用于这一个额外的标题:

'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',

Answer 2

这将适用于Python 3

import urllib.request

user_agent = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7'

url = "http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers"
headers={'User-Agent':user_agent,} 

request=urllib.request.Request(url,None,headers) #The assembled request
response = urllib.request.urlopen(request)
data = response.read() # The data u need

Answer 3

当您请求的服务器不知道请求来自何处时，通常会发生此错误，服务器这样做是为了避免任何不需要的访问。您可以通过定义标头并将其沿 urllib.request 传递来绕过此错误

继承人代码：

#defining header
header= {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) ' 
      'AppleWebKit/537.11 (KHTML, like Gecko) '
      'Chrome/23.0.1271.64 Safari/537.11',
      'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
      'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
      'Accept-Encoding': 'none',
      'Accept-Language': 'en-US,en;q=0.8',
      'Connection': 'keep-alive'}

#the URL where you are requesting at
req = urllib.request.Request(url=your_url, headers=header) 
page = urllib.request.urlopen(req).read()

NSE网站已经改变,旧的脚本对当前网站来说是半最优的.此代码段可以收集每日安全细节.详情包括符号,证券类型,前期收盘价,开盘价,高价,低价,平均价,交易数量,营业额,交易数量,可交割数量以及交割与交易的比率(以百分比表示).这些方便地呈现为字典表格列表.

带有请求的Python 3.X版本和BeautifulSoup

from requests import get
from csv import DictReader
from bs4 import BeautifulSoup as Soup
from datetime import date
from io import StringIO 

SECURITY_NAME="3MINDIA" # Change this to get quote for another stock
START_DATE= date(2017, 1, 1) # Start date of stock quote data DD-MM-YYYY
END_DATE= date(2017, 9, 14)  # End date of stock quote data DD-MM-YYYY


BASE_URL = "https://www.nseindia.com/products/dynaContent/common/productsSymbolMapping.jsp?symbol={security}&segmentLink=3&symbolCount=1&series=ALL&dateRange=+&fromDate={start_date}&toDate={end_date}&dataType=PRICEVOLUMEDELIVERABLE"




def getquote(symbol, start, end):
    start = start.strftime("%-d-%-m-%Y")
    end = end.strftime("%-d-%-m-%Y")

    hdr = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11',
         'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
         'Referer': 'https://cssspritegenerator.com',
         'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.3',
         'Accept-Encoding': 'none',
         'Accept-Language': 'en-US,en;q=0.8',
         'Connection': 'keep-alive'}

    url = BASE_URL.format(security=symbol, start_date=start, end_date=end)
    d = get(url, headers=hdr)
    soup = Soup(d.content, 'html.parser')
    payload = soup.find('div', {'id': 'csvContentDiv'}).text.replace(':', '\n')
    csv = DictReader(StringIO(payload))
    for row in csv:
        print({k:v.strip() for k, v in row.items()})


 if __name__ == '__main__':
     getquote(SECURITY_NAME, START_DATE, END_DATE)

此外,这是相对模块化和随时可用的代码段.
