从熊猫0.19.2开始,可以向函数read_csv()传递URL。例如,参见此answer:
import pandas as pd
url="https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv"
c=pd.read_csv(url)
我要使用的URL是:https://moz.com/top500/domains/csv
使用上面的代码,该URL返回错误:
urllib2.HTTPError: HTTP Error 403: Forbidden
基于this post,我可以通过传递请求标头来获得有效的响应:
import urllib2,cookielib
site= "https://moz.com/top500/domains/csv"
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)
是否可以使用Pandas read_csv()
的Web URL功能,还可以传递请求标头以使请求通过?
答案 0 :(得分:1)
我建议您将requests和io库用于任务。以下代码可以完成这项工作:
import pandas as pd
import requests
from io import StringIO
url = "https://moz.com:443/top500/domains/csv"
headers = {"User-Agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:66.0) Gecko/20100101 Firefox/66.0"}
req = requests.get(url, headers=headers)
data = StringIO(req.text)
df = pd.read_csv(data)
print(df)
(如果要添加自定义标头,只需修改headers
变量)
希望这会有所帮助
