Question

我一直在使用以下网址从雅虎财经获取历史数据已有一段时间了，但截至昨天它已停止工作。

https://ichart.finance.yahoo.com/table.csv?s=SPY

浏览本网站时说：

马上回来......

感谢您的耐心等待。

我们的工程师正在迅速解决这个问题。

但是，由于这个问题自昨天起仍然存在，我开始认为他们已经停止了这项服务？

我的SO搜索仅指向this topic，这与https虽然相关......

还有其他人遇到此问题吗？我该如何解决这个问题？他们是否提供对历史数据的不同访问权限？

Answer 1

看起来他们已经开始添加必需的Cookie，但您可以相当轻松地检索它，例如：

GET https://uk.finance.yahoo.com/quote/AAPL/history

回复表单中的标题：

set-cookie:B=xxxxxxxx&b=3&s=qf; expires=Fri, 18-May-2018 00:00:00 GMT; path=/; domain=.yahoo.com

您应该可以阅读此内容并将其附加到.csv请求中：

GET https://query1.finance.yahoo.com/v7/finance/download/AAPL?period1=1492524105&period2=1495116105&interval=1d&events=history&crumb=tO1hNZoUQeQ
cookie: B=xxxxxxxx&b=3&s=qf;

请注意crumb查询参数，这似乎与您cookie的某种方式相对应。您最好的选择是从您对初始GET请求的HTML响应中scrape这个。在该响应中，您可以执行正则表达式搜索："CrumbStore":\{"crumb":"(?<crumb>[^"]+)"\}并提取crumb匹配组。

看起来，只要您拥有crumb值，虽然您可以在明年的任何符号/代码上使用相同的cookie，这意味着您不应该{ {1}}过于频繁。

要获取当前报价，只需加载：

使用：

AAPL替换为您的股票代码
https://query1.finance.yahoo.com/v8/finance/chart/AAPL?interval=2m
带有您的纪元范围开始日期的可选[1m, 2m, 5m, 15m, 30m, 60m, 90m, 1h, 1d, 5d, 1wk, 1mo, 3mo]查询参数，例如period1
带有您的纪元范围结束日期的可选period1=1510340760查询参数，例如period2

Answer 2

Yahoo已进入Reactjs前端，这意味着如果您分析从客户端到后端的请求标头，您可以获得他们用来填充客户端商店的实际JSON。

主机：

query1.finance.yahoo.com HTTP / 1.0
query2.finance.yahoo.com HTTP / 1.1 （difference between HTTP/1.0 & HTTP/1.1）

如果您打算使用代理或持久连接，请使用query2.finance.yahoo.com。但就本文而言，用于示例网址的主机并不意味着暗示与其一起使用的路径。

基本数据

/v10/finance/quoteSummary/AAPL?modules=（以下模块的完整列表）

（将您的符号替换为：AAPL）

?modules=查询的输入：

modules = [ 'assetProfile', 'incomeStatementHistory', 'incomeStatementHistoryQuarterly', 'balanceSheetHistory', 'balanceSheetHistoryQuarterly', 'cashflowStatementHistory', 'cashflowStatementHistoryQuarterly', 'defaultKeyStatistics', 'financialData', 'calendarEvents', 'secFilings', 'recommendationTrend', 'upgradeDowngradeHistory', 'institutionOwnership', 'fundOwnership', 'majorDirectHolders', 'majorHoldersBreakdown', 'insiderTransactions', 'insiderHolders', 'netSharePurchaseActivity', 'earnings', 'earningsHistory', 'earningsTrend', 'industryTrend', 'indexTrend', 'sectorTrend' ]

示例网址

https://query1.finance.yahoo.com/v10/finance/quoteSummary/AAPL?modules=assetProfile%2CearningsHistory

查询：assetProfile和earningsHistory

%2C是,的十六进制表示，需要在您请求的每个模块之间插入。 details about the hex encoding bit（如果你关心的话）

期权合约

/v7/finance/options/AAPL（当前到期日）
/v7/finance/options/AAPL?date=1579219200（2020年1月17日到期）

示例网址

https://query2.yahoo.finance.com/v7/finance/options/AAPL（当前到期日）
https://query2.yahoo.finance.com/v7/finance/options/AAPL?date=1579219200（2020年1月17日到期）

可以在?date=查询中使用表示为UNIX时间戳的任何有效的未来到期时间。如果查询当前过期，则JSON响应将包含可在?date=查询中使用的所有有效过期的列表。 (here is a post explaining converting human readable dates to unix timestamp in Python)

价格

/v8/finance/chart/AAPL?symbol=AAPL&period1=0&period2=9999999999&interval=3mo

<强>间隔：

&interval=3mo 3个月，回到最初的交易日期。
&interval=1d 1天，回到最初的交易日期。
&interval=5m 5分钟，回到80（ish）天。
&interval=1m 1小时，回到4-5天。

每个间隔你能走多远，有点混乱，似乎不一致。我的假设是内部雅虎在交易日计算，而我的天真方法并不是假期。虽然这是一个猜测和YMMV。

period1=：您希望开始的日期的unix时间戳表示。低于初始交易日的价值将四舍五入到初始交易日。

period2=：您希望结束的日期的unix时间戳表示。大于上次交易日期的值将向下舍入到最新的可用时间戳。

注意： 如果您使用的period1=（开始日期）在您选择的时间间隔内查询过多，yahoo将返回价格在3mo间隔内，无论您请求的间隔是什么。

添加pre＆amp;发布市场数据

&includePrePost=true

添加红利＆amp;分割

&events=div%2Csplit

示例网址

https://query1.finance.yahoo.com/v8/finance/chart/AAPL?symbol=AAPL&period1=0&period2=9999999999&interval=1d&includePrePost=true&events=div%2Csplit

上述请求将在1天的时间间隔内返回股票代码AAPL的所有价格数据，包括市场前和后市场数据以及股息和拆分。

注意： period1=＆amp;的价格示例网址中使用的值period2=用于演示每个输入的相应舍入行为。

Answer 6

下载历史数据的URL现在是这样的：

https://query1.finance.yahoo.com/v7/finance/download/SPY?period1=1492449771&period2=1495041771&interval=1d&events=history&crumb=9GaimFhz.WU

请注意，上述网址不适合您或其他任何人。你会得到这样的东西：

{
    "finance": {
        "error": {
            "code": "Unauthorized",
            "description": "Invalid cookie"
        }
    }
}

雅虎现在似乎正在使用一些哈希来阻止人们像你一样访问数据。网址因每个会话而异，因此您很可能不再使用固定网址执行此操作。

您需要进行一些报废才能从主页面获取正确的网址，例如：

https://finance.yahoo.com/quote/SPY/history?p=SPY

Answer 7

我找到了另一个不需要cookie的雅虎网站，但产生了jason输出：https://query1.finance.yahoo.com/v7/finance/chart/YHOO?range=2y&interval=1d&indicators=quote&includeTimestamps=true

从这里指出：https://www.stock-data-solutions.com/kb/how-to-load-historical-prices-from-yahoo-finance-to-excel.htm

事实证明，它们似乎支持'perod1'和'period2'（在unix时间内）参数，可以用来代替'interval'。

String quoteSite = "https://query1.finance.yahoo.com/v7/finance/chart/"
                   + symbolName + "?"
                   + "period1=" + period1
                   + "&period2=" + period2
                   + "&interval=1d&indicators=quote&includeTimestamps=true";

以下解析Jason：

JSONObject topObj = new JSONObject(inp);
Object error = topObj.getJSONObject("chart").get("error");
if (!error.toString().equals("null")) {
    System.err.prinltn(error.toString());
    return null;
}
JSONArray results = topObj.getJSONObject("chart").getJSONArray("result");
if (results == null || results.length() != 1) {
    return null;
}
JSONObject result = results.getJSONObject(0);
JSONArray timestamps = result.getJSONArray("timestamp");
JSONObject indicators = result.getJSONObject("indicators");
JSONArray quotes = indicators.getJSONArray("quote");
if (quotes == null || quotes.length() != 1) {
    return null;
}
JSONObject quote = quotes.getJSONObject(0);
JSONArray adjcloses = indicators.getJSONArray("adjclose");
if (adjcloses == null || adjcloses.length() != 1) {
   return null;
}
JSONArray adjclose = adjcloses.getJSONObject(0).getJSONArray("adjclose");
JSONArray open = quote.getJSONArray("open");
JSONArray close = quote.getJSONArray("close");
JSONArray high = quote.getJSONArray("high");

完全正常工作 PHP示例，基于此帖子和相关来源：

function readYahoo($symbol, $tsStart, $tsEnd) {
  preg_match('"CrumbStore\":{\"crumb\":\"(?<crumb>.+?)\"}"',
    file_get_contents('https://uk.finance.yahoo.com/quote/' . $symbol),
    $crumb);  // can contain \uXXXX chars
  if (!isset($crumb['crumb'])) return 'Crumb not found.';
  $crumb = json_decode('"' . $crumb['crumb'] . '"');  // \uXXXX to UTF-8
  foreach ($http_response_header as $header) {
    if (0 !== stripos($header, 'Set-Cookie: ')) continue;
    $cookie = substr($header, 14, strpos($header, ';') - 14);  // after 'B='
  }  // cookie looks like "fkjfom9cj65jo&b=3&s=sg"
  if (!isset($cookie)) return 'Cookie not found.';
  $fp = fopen('https://query1.finance.yahoo.com/v7/finance/download/' . $symbol
    . '?period1=' . $tsStart . '&period2=' . $tsEnd . '&interval=1d'
    . '&events=history&crumb=' . $crumb, 'rb', FALSE,
    stream_context_create(array('http' => array('method' => 'GET',
      'header' => 'Cookie: B=' . $cookie))));
  if (FALSE === $fp) return 'Can not open data.';
  $buffer = '';
  while (!feof($fp)) $buffer .= implode(',', fgetcsv($fp, 5000)) . PHP_EOL;
  fclose($fp);
  return $buffer;
}

<强>用法：

$csv = readYahoo('AAPL', mktime(0, 0, 0, 6, 2, 2017), mktime(0, 0, 0, 6, 3, 2017));

Answer 9

对于java爱好者。

您可以通过这种方式从URLConnection访问您的Cookie。

 //  "https://finance.yahoo.com/quote/SPY";
 URLConnection con = url.openConnection();
 ...  
 for (Map.Entry<String, List<String>> entry : con.getHeaderFields().entrySet()) {
        if (entry.getKey() == null 
            || !entry.getKey().equals("Set-Cookie"))
            continue;
        for (String s : entry.getValue()) {
           // store your cookie
           ...
        }
 }

现在你可以在雅虎网站上搜索crumb：

String crumb = null;
InputStream inStream = con.getInputStream();
InputStreamReader irdr = new InputStreamReader(inStream);
BufferedReader rsv = new BufferedReader(irdr);

Pattern crumbPattern = Pattern.compile(".*\"CrumbStore\":\\{\"crumb\":\"([^\"]+)\"\\}.*");

String line = null;
while (crumb == null && (line = rsv.readLine()) != null) {
    Matcher matcher = crumbPattern.matcher(line);
    if (matcher.matches()) 
        crumb = matcher.group(1);
}
rsv.close();

最后，设置cookie

String quoteUrl = "https://query1.finance.yahoo.com/v7/finance/download/IBM?period1=1493425217&period2=1496017217&interval=1d&events=history&crumb="
                           + crumb
...
List<String> cookies = cookieStore.get(key);
if (cookies != null) {
    for (String c: cookies) 
        con.setRequestProperty("Cookie", c);
}
...
con.connect();

Answer 10

我在同一条船上。慢慢到达那里。历史价格页面上的下载链接仍然有效。所以我将导出cookie扩展添加到firefox，登录到yahoo，转储cookie。使用交互式会话中的crumb值，我能够检索值。这是测试perl脚本的一部分。

use Time::Local;

# create unix time variables for start and end date values: 1/1/2014 thru 12/31/2017
$p1= timelocal(0,0,0,1,0,114);
$p2= timelocal(0,0,0,31,11,117);

$symbol = 'AAPL';

# create variable for string to be executed as a system command
# cookies.txt exported from firefox
# crumb variable retrieved from yahoo download data link
$task = "wget --load-cookies cookies.txt --no-check-certificate -T 30 -O          $symbol.csv \"https://query1.finance.yahoo.com/v7/finance/download/$symbol?period1=$p1&period2=$p2&interval=1d&events=history&crumb=7WhHVu5N4e3\" ";

#show what we're executing
print $task;

# execute system command using backticks
`$task`;

#output is AAPL.csv

我需要一段时间来自动完成我的工作。希望雅虎能够简化或提供一些指导，如果他们真的打算让人们使用它。

Answer 11

的Python

我使用此代码获取Cookie（从fix-yahoo-finance复制）：

def get_yahoo_crumb_cookie():
    """Get Yahoo crumb cookie value."""
    res = requests.get('https://finance.yahoo.com/quote/SPY/history')
    yahoo_cookie = res.cookies['B']
    yahoo_crumb = None
    pattern = re.compile('.*"CrumbStore":\{"crumb":"(?P<crumb>[^"]+)"\}')
    for line in res.text.splitlines():
        m = pattern.match(line)
        if m is not None:
            yahoo_crumb = m.groupdict()['crumb']
    return yahoo_cookie, yahoo_crumb

然后这段代码得到回应：

cookie, crumb = get_yahoo_crumb_cookie()
params = {
    'symbol': stock.symbol,
    'period1': 0,
    'period2': int(time.time()),
    'interval': '1d',
    'crumb': crumb,
}
url_price = 'https://query1.finance.yahoo.com/v7/finance/download/{symbol}'

response = requests.get(url_price, params=params, cookies={'B': cookie})

Answer 12

我使用了一个使用fopen（）的php脚本来访问财务数据，以下是我修改后的片段，以使其恢复工作：

创建开始日期和结束日期的时间戳：

$timestampStart = mktime(0,0,0,$startMonth,$startDay,$startYear);
$timestampEnd = mktime(0,0,0,$endMonth,$endDay,$endYear);

强制fopen（）发送带有硬编码值的必需cookie：

$cookie="YourCookieTakenFromYahoo";

$opts = array(
    'http'=>array(
        'method'=>"GET",
        'header'=>"Accept-language: en\r\n" .
            "Cookie: B=".$cookie."\r\n"
    )
);

$context = stream_context_create($opts);

使用fopen（）获取csv文件：

$ticker="TickerSymbol";
$crumb="CrumbValueThatMatchesYourCookieFromYahoo";

$handle = fopen("https://query1.finance.yahoo.com/v7/finance/download/".$ticker."?period1=".$timestampStart."&period2=".$timestampEnd."&interval=1d&events=history&crumb=".$crumb."", "r", false, $context);

现在你可以在这个while循环中做你所做的所有魔术：

while (!feof($handle) ) {
    $line_of_text = fgetcsv($handle, 5000);
}

请务必在上面的代码段中为$ticker，$crumb和$cookie设置自己的值。关注如何检索$crumb和$cookie。

对于那些Excel / VBA用户，我使用上述建议开发了一个VBA方法，以从更新的Yahoo网站中提取历史价格。下面列出了关键代码段，我还提供了测试工作簿。

首先要求在尝试从Yahoo提取数据之前获取Crumb和Cookie值的设置..

Dim strUrl                      As String: strUrl = "https://finance.yahoo.com/lookup?s=%7B0%7D"    'Symbol lookup used to set the values
Dim objRequest                  As WinHTTP.WinHttpRequest

Set objRequest = New WinHttp.WinHttpRequest

With objRequest
    .Open "GET", strUrl, True
    .setRequestHeader "Content-Type", "application/x-www-form-urlencoded; charset=UTF-8"
    .send
    .waitForResponse
    strCrumb = strExtractCrumb(.responseText)
    strCookie = Split(.getResponseHeader("Set-Cookie"), ";")(0)
End With

请参阅我的网站的以下Yahoo Historical Price Extract链接以获取示例文件以及我用于从Yahoo网站提取历史安全价格的方法的更多详细信息

Answer 16

到目前为止提到的那种方法（雅虎，谷歌和Intrinio）的另一种方法是免费获取Alpha Vantage的历史数据。他们的网络服务提供日内，每日，调整后的股票价格和50多项技术指标。他们甚至可以通过Deriscope直接发送到Excel - 也是免费的。（我是后者的作者。）

Answer 17

的Javascript

查找cookie;

match = document.cookie.match(new RegExp('B=([^;]+)'));
alert (match[1]);

找到面包屑;

i=document.body.innerHTML.search("CrumbStore")
if (i>=0) alert (document.body.innerHTML.substr(i+22,11))

查找移动设备的碎屑;

i=document.body.innerHTML.search('USER={\"crumb\":'); 
if (i>=0) alert(document.body.innerHTML.substr(i+15,11));

并且可能最好等待页面（例如https://finance.yahoo.com/quote/goog）先加载，你可以检查一下;

document.readyState

Answer 18

为什么不使用提供完全访问权限的现成版本。没有故障：

tickers='AAPL' 

from pandas_datareader import data as wb

new_data = pd.DataFrame()
for t in tickers :

    new_data[t] = wb.DataReader(t, data_source ='yahoo', start = '2004-1-1')['Adj Close']

a = new_data[t]

Answer 19

你实际上并不需要做2个获取雅虎数据的请求。我使用此链接https://ca.finance.yahoo.com/quote/AAAP/history?period1=1474000669&period2=1505536669&interval=1d&filter=history&frequency=1d

你可以从中获取cookie，但它包含了JSON格式的历史报价数据。下载页面后，我将Json数据从中删除。保存网址请求。

Answer 20

我在同一条船上。我设法从雅虎下载了一些vb.net frankencode，这些代码是我用谷歌，SOF和一些令人头疼的东西制作而成的。

然而，我发现了Intrinio（查找），注册了，我的免费帐户每天为我提供500个历史数据api调用，拥有更多数据并且比雅虎准确得多。我重写了我的Intrinio API代码，我很高兴作为一个蛤蜊。

顺便说一句，我不工作或与Intrinio有任何关系，但是他们节省了我的屁股时间......

Answer 21

我发现有一个修复工作正常。请看我的帖子：

Yahoo Finance API / URL not working: Python fix for Pandas DataReader我按照https://pypi.python.org/pypi/fix-yahoo-finance中的步骤执行：$ pip install fix_yahoo_finance --upgrade --no-cache-dir（并且还升级了pandas_datareader以确定）并且测试正常：

from pandas_datareader import data as pdr
import fix_yahoo_finance

data = pdr.get_data_yahoo('BHP.AX', start='2017-04-23', end='2017-05-24')

另请注意，最后2个数据列的顺序是“Adj Close”和“Volume”，所以出于我的目的，我已将列重置为原始顺序：

cols = ['Date', 'Open', 'High', 'Low', 'Close', 'Volume', 'Adj Close']
data = data.reindex(columns=cols)

Answer 22

可以从documentation获取当前和历史数据。对我来说非常好。

Answer 23

对于Python 3，用户更改为

URL = 'https://query1.finance.yahoo.com/v7/finance/download/AAAP?period1=1494605670&period2=1495815270&interval=1d&events=history&crumb=IJ.ilcJlkrZ'

来自

URL = 'https://chartapi.finance.yahoo.com/instrument/1.0/AAAP/chartdata;type=quote;range=10d/csv/'

和

response = request.urlopen（url）至 response = requests.get（url，cookies = {'B'：cookie}） response.text中的数据

数据格式完全不同，但至少它现在正常工作
