问题:urllib2.HTTPError:HTTP错误403:禁止
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用CSV文件响应,但是我无法使用urllib2打开。我曾尝试按照前面几个问题中的说明更改用户代理,甚至尝试接受响应cookie,但没有运气。你能帮忙吗?
注意:相同的方法适用于yahoo Finance。
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
http_error_default中的文件“ C:\ Python27 \ lib \ urllib2.py”,第527行,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

通过添加更多头,我可以获取数据:
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,它仅与此一个附加头一起工作:
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',

这将在Python 3中工作
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

NSE网站已更改,较旧的脚本是当前网站的半最佳状态。此摘要可以收集安全性的日常细节。详细信息包括代码,证券类型,先前收盘价,开盘价,高价,低价,平均价格,交易数量,营业额,交易数量,可交付数量以及已交付与交易的比率(百分比)。这些方便地以字典形式的列表形式呈现。
带有请求和BeautifulSoup的Python 3.X版本
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,这是相对模块化的,可以使用摘要。
