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。
代码:
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,http_error_default 引发HTTPError(req.get_full_url(),code,msg,hdrs,fp)urllib2.HTTPError:HTTP错误403:禁止
感谢您的协助

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',

这将在Python 3中起作用
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,旧版脚本对当前网站来说是半优化的。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)。这些方便地列为字典表格。
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

def getquote(symbol, start, end):

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',

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,它是相对模块化的,随时可以使用的代码段。

这个错误通常发生在您请求的服务器不知道请求来自哪里时,服务器这样做是为了避免任何不必要的访问。您可以通过定义标头并将其沿 urllib.request 传递来绕过此错误
这里的代码:
#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()

有一件值得尝试的事情就是更新python版本。几个月前,我的一个抓取脚本在 Windows 10 上停止使用 403。任何 user_agents 都没有帮助,我即将放弃脚本。今天,我用 Python(3.8.5 - 64 位)在 Ubuntu 上尝试了相同的脚本,并且没有错误。 Windows 的 python 版本有点旧,因为 3.6.2 - 32 位。将 Windows 10 上的 python 升级到 3.9.5 - 64 位后,我再也看不到 403 了。如果您尝试一下,请不要忘记运行“pip freeze > requirements.txt”来导出包条目。我当然忘记了。 这个帖子也是对我以后403再来的提醒。
