Question

我试图从雅虎查询中下载AAPL的历史股票价格，但失败了。我是python的新手，不知道应用哪种方法将指定的链接自动解压缩到我想要的本地目录。

pullData（＆＃34; AAPL＆＃34;）结果如下：     AAPL     https://query1.finance.yahoo.com/v7/finance/download/AAPL?period1=345398400&period2=1505577600&interval=1d&events=history&crumb=X44gAJPyoNu     主循环HTTP错误401：未经授权

import urllib2
import time
import csv
import requests
import pandas as pd

def pullData(stock):
    try:
        print stock
        url = 'https://query1.finance.yahoo.com/v7/finance/download/'+stock+'?period1=345398400&period2=1505577600&interval=1d&events=history&crumb=X44gAJPyoNu'
        print url

        response = urllib2.urlopen(url)
        html = response.read()


    except Exception,e:
        print 'main loop',str(e)

您应该使用此修复程序更新pandas datareader https://github.com/pydata/pandas-datareader/issues/315

import pandas as pd
from pandas_datareader import data as web

start = datetime.datetime(2015, 7, 1)
end = datetime.datetime(2016, 7, 1)
data - web.DataReader('AAPL', 'yahoo',start, end)
