错误
我尝试使用python自动下载历史股票数据。当打开的URL会以CSV文件响应,但我无法使用urllib2打开。我尝试过按照前面几个问题中的说明更改用户代理,我甚至尝试接受响应cookie,但没有成功。
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)
报错:
File “C:\Python27\lib\urllib2.py”, line 527, in http_error_default raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) urllib2.HTTPError: HTTP Error 403: Forbidden
解决办法
方法一:
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,它只需要一个额外的标题:
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
方法二:
如果不行,可以试一下以下的方法:
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
