Not being able to acess google financial historial data

Answer 1

问题不在于您的代码，而是Google对您查询的支持。如果要手动GET生成的URL：

import requests
requests.get('http://www.google.com/finance/historical?q=SPY&startdate=Jan+01%2C+2010&enddate=Aug+17%2C+2018&output=csv')
# results in <Response [403]>

您会注意到该URL结果显示为403，这意味着禁止访问该URL。结果，您得到了pandas_datareader._utils.RemoteDataError: Unable to read URL

无法读取URL pandas_datareader
