wget 无法再下载雅虎财经数据了

问题描述 投票:0回答:2

从几周前开始,我就无法再下载雅虎财经数据了:

$ wget -O GLD.USA_20170612.txt --no-check-certificate http://chart.finance.yahoo.com/table.csv?s=GLD&a=2&b=1&c=2017&d=11&e=30&f=2017&ignore=.csv

他们改变了一些东西。我从网站上获取了一个新的 URL,但它仍然不起作用:

$ wget https://query1.finance.yahoo.com/v7/finance/download/GLD?period1=1494584558&period2=1497262958&interval=1d&events=history&crumb=GGHpj6ucgIy

我不明白为什么它提到用户名和密码。当我单击 https://uk.finance.yahoo.com/quote/GLD/history?p=GLD 上的“下载”按钮时,它不会要求输入用户名和密码。看来不用订阅也能下载数据了。

如果有人知道下载雅虎财务数据的正确 wget 实现,请在此处分享。

更新:

感谢当前的回复,我被暗示这里可能涉及“cookies”。在关键字中搜索cookie的类似问题时,我发现了以下线程:

雅虎财经历史数据下载网址不起作用

雅虎财经网址无法使用

不幸的是这对我来说太复杂了...... 我希望能为这项工作提供一点帮助。

为了处理 Yahoo cokies,我编写了以下代码:

#!/usr/bin/sh

symbol=$1
today=$(date +%Y%m%d)
tomorrow=$(date --date='1 days' +%Y%m%d)

first_date=$(date -d "$2" '+%s')
last_date=$(date -d "$today" '+%s')

wget --no-check-certificate --save-cookies=cookie.txt https://finance.yahoo.com/quote/$symbol/?p=$symbol -O crumb.store

crumb=$(grep 'root.*App' crumb.store | sed 's/,/\n/g' | grep CrumbStore | sed 's/"CrumbStore":{"crumb":"\(.*\)"}/\1/')

wget --no-check-certificate --load-cookies=cookie.txt "https://query1.finance.yahoo.com/v7/finance/download/$symbol?period1=$first_date&period2=$last_date&interval=1d&events=history&crumb=$crumb" -O $symbol.csv

rm cookie.txt crumb.store

使用示例:

$ sh stockdownload_yahoo.sh QQQ 20170508

支持的日期格式示例:

$ date -d 20170328 +%s
1490652000
$ date -d 2017-03-28 +%s
1490652000
$ date -d "Mar 28 2017" +%s
1490652000

现在仅适用于高级用户 - 黄金用户(每月 50 美元!)。 这很不幸。
