如何通过Google财经等API获取货币汇率？

Question

现在,我确实找到了Google财经API并开始查看,但我发现了很多关于投资组合,交易,头寸和其他我一无所知的信息.

我在查看错误的文档吗？我需要做些什么来从GF获得汇率？这甚至可能吗？

编辑

让事情变得更加清晰.我对技术方面不感兴趣,也不想要任何代码.

Answer 1

谢谢你的所有答案.

   这个CSV正在使用由一个名为jQuery插件库里.由于稳定性问题,库里已经(2017-08-29)转而使用fixer.io.如果您需要的不仅仅是CSV,可能会很有用.

Answer 3

雅虎有一个YQL功能,可以在XML或JSON中同时获得一大堆货币.我注意到数据是按照欧洲央行拥有日常数据的那一刻的最新数据,并在周末停止.

http://query.yahooapis.com/v1/public/yql?q=select*from yahoo.finance.xchange where in in("USDEUR","USDJPY","USDBGN","USDCZK","USDDKK", "USDGBP","USDHUF","USDLTL","USDLVL","USDPLN","USDRON","USDSEK","USDCHF","USDNOK","USDHRK","USDRUB","USDTRY","USDAUD ","USDBRL","USDCAD","USDCNY","USDHKD","USDIDR","USDILS","USDINR","USDKRW","USDMXN","USDMYR","USDNZD","USDPHP", "USDSGD","USDTHB","USDZAR","USDISK")&env = store://datatables.org/alltableswithkeys

这是他们的查询构建器,您可以在其中测试查询并复制URL:

http://developer.yahoo.com/yql/console/?q=show%20tables&env=store://datatables.org/alltableswithkeys#h=select%20*%20from%20yahoo.finance.xchange%20where%20pair% 20英寸%20%28%22USDMXN%22%2C%20%22USDCHF%22%29

Answer 4

如果您需要一个免费且简单的API来将一种货币转换为另一种货币,请尝试free.currencyconverterapi.com.

免责声明,我是该网站的作者,我将其用于我的其他网站.

该服务即使是商业应用也可免费使用,但不提供保修.出于性能原因,值仅每小时更新一次.

示例转换URL为:http://free.currencyconverterapi.com/api/v6/convert？q = EUR_PHP&compact = _ultra&apiKey = sample -api-key,它将返回json格式的值,例如{"EUR_PHP":60.849184}

Answer 5

我从http://www.scriptarticle.com/2012/05/03/get-live-currency-rates-and-currency-conversion-using-php-and-apis/获得了这些内容

<?php

function get_currency($from_Currency, $to_Currency, $amount) {
    $amount = urlencode($amount);
    $from_Currency = urlencode($from_Currency);
    $to_Currency = urlencode($to_Currency);

    $url = "http://www.google.com/finance/converter?a=$amount&from=$from_Currency&to=$to_Currency";

    $ch = curl_init();
    $timeout = 0;
    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt ($ch, CURLOPT_USERAGENT,
                 "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $rawdata = curl_exec($ch);
    curl_close($ch);
    $data = explode('bld>', $rawdata);
    $data = explode($to_Currency, $data[1]);

    return round($data[0], 2);
}

// Call the function to get the currency converted
echo get_currency('USD', 'INR', 1);

?>

Answer 6

以下是一些使用PHP示例的交换API.

[ 开放汇率API ]

每月免费提供1,000个请求.您必须注册并获取App ID.免费帐户的基础货币USD.查看支持的货币和文档.

// open exchange URL // valid app_id * REQUIRED *
$exchange_url = 'https://openexchangerates.org/api/latest.json';
$params = array(
    'app_id' => 'YOUR_APP_ID'
);

// make cURL request // parse JSON
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => $exchange_url . '?' . http_build_query($params),
    CURLOPT_RETURNTRANSFER => true
));
$response = json_decode(curl_exec($curl));
curl_close($curl);

if (!empty($response->rates)) {
    // convert 150 USD to JPY ( Japanese Yen )
    echo $response->rates->JPY * 150;
}

150美元= 18039.09015日元

[ 货币层API ]

每月免费提供1,000个请求.您必须注册并获取访问密钥.免费帐户不支持自定义基本货币.查看文档.

$exchange_url = 'http://apilayer.net/api/live';
$params = array(
    'access_key' => 'YOUR_ACCESS_KEY',
    'source' => 'USD',
    'currencies' => 'JPY',
    'format' => 1 // 1 = JSON
);

// make cURL request // parse JSON
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => $exchange_url . '?' . http_build_query($params),
    CURLOPT_RETURNTRANSFER => true
));
$response = json_decode(curl_exec($curl));
curl_close($curl);

if (!empty($response->quotes)) {
    // convert 150 USD to JPY ( Japanese Yen )
    echo '150 USD = ' . $response->quotes->USDJPY * 150 . ' JPY';
}

150美元= 18036.75045日元
