如何通过 Google Finance 等 API 获取货币汇率?

发布于 2024-09-07 10:17:57 字数 258 浏览 5 评论 0原文

现在,我确实找到了 Google Finance API 并开始浏览它,但我发现了很多有关投资组合、交易、头寸和信息的信息其他我一无所知的事情。

我看错文档了吗?我需要做什么才能从 GF 获取汇率信息?这可能吗?

编辑

让事情变得更清楚一些。我对技术内容不感兴趣,也不想要任何代码。

Now, I did find the Google Finance API and started looking through that but I found a lot of info about portfolios, transactions, positions & other stuff I know nothing about.

Am I looking at the wrong docs? What do I need to do to get a feed of exchange rates from GF? Is this even possible?

EDIT

To make things a little clearer. I'm not interested in technical stuff nor do I want any code.

Discontinued as of 2017-11-06 with message

It has come to our attention that this service is being used in

This CSV was being used by a jQuery plugin called Curry. Curry has since (2017-08-29) moved to use fixer.io instead due to stability issues.
Might be useful if you need more than just a CSV.

以下是一些使用 PHP 进行交换 API 的示例。

[ 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。免费账户的基础货币为美元。检查支持的货币文档

// 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。免费帐户支持自定义基础货币。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

Here are some exchange APIs with PHP example.

[ Open Exchange Rates API ]

Provides 1,000 requests per month free. You must register and grab the App ID. The base currency USD for free account. Check the supported currencies and documentation.

// 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 USD = 18039.09015 JPY

[ Currency Layer API ]

Provides 1,000 requests per month free. You must register and grab the Access KEY. Custom base currency is not supported in free account. Check the documentation.

$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 USD = 18036.75045 JPY

除了通过IP进行地理定位之外,您还可以尝试geoplugin

(但IP是提供商IP,所以不太准确) ,它们还返回货币并具有货币转换器:请参阅示例。

他们更新了 111 种货币。

You can try geoplugin

Beside the geolocation done by IP (but the IP is the provider IP, so not so accurate), they return currencies also and have a currency converter: see examples.

They have 111 currencies updated.

如果您正在寻找基于 ruby​​ 的解决方案来解决此问题,我建议使用 Google 计算器方法,该解决方案类似于以下内容:http ://j.mp/QIC564

require 'faraday'
require 'faraday_middleware'
require 'json'

# Debug: 
# require "pry"


country_code_src = "USD"
country_code_dst = "INR"
connection = Faraday.get("http://www.google.com/ig/calculator?hl=en&q=1#{country_code_src}=?#{country_code_dst}")

currency_comparison_hash = eval connection.body #Google's output is not JSON, it's a hash

dst_currency_value, *dst_currency_text = *currency_comparison_hash[:rhs].split(' ')
dst_currency_value = dst_currency_value.to_f
dst_currency_text = dst_currency_text.join(' ')

puts "#{country_code_dst} -> #{dst_currency_value} (#{dst_currency_text} to 1 #{country_code_src})"

If you're looking for a ruby based solution for this problem, I recommend using the Google Calculator method a solution similar to the following: http://j.mp/QIC564

require 'faraday'
require 'faraday_middleware'
require 'json'

# Debug: 
# require "pry"


country_code_src = "USD"
country_code_dst = "INR"
connection = Faraday.get("http://www.google.com/ig/calculator?hl=en&q=1#{country_code_src}=?#{country_code_dst}")

currency_comparison_hash = eval connection.body #Google's output is not JSON, it's a hash

dst_currency_value, *dst_currency_text = *currency_comparison_hash[:rhs].split(' ')
dst_currency_value = dst_currency_value.to_f
dst_currency_text = dst_currency_text.join(' ')

puts "#{country_code_dst} -> #{dst_currency_value} (#{dst_currency_text} to 1 #{country_code_src})"

这是一个简单的 PHP 脚本,它获取英镑和美元之间的汇率

<?php
$amount = urlencode("1");
$from_GBP0 = urlencode("GBP");
$to_usd= urlencode("USD");
$Dallor = "hl=en&q=$amount$from_GBP0%3D%3F$to_usd";
$US_Rate = file_get_contents("http://google.com/ig/calculator?".$Dallor);
$US_data = explode('"', $US_Rate);
$US_data = explode(' ', $US_data['3']);
$var_USD = $US_data['0'];
echo $to_usd;
echo $var_USD;
echo '<br/>'; 
?>

谷歌货币汇率不准确谷歌自己说 ==> Google 无法保证计算器使用的汇率的准确性。在进行可能受汇率变化影响的任何交易之前,您应该确认当前汇率。花旗银行 NA 提供的外币汇率根据许可显示。价格仅供参考,如有更改,恕不另行通知。实际交易的汇率可能会有所不同,花旗银行不提供以任何显示的汇率进行任何交易。

Here is one simple PHP Script which gets exchange rate between GBP and USD

<?php
$amount = urlencode("1");
$from_GBP0 = urlencode("GBP");
$to_usd= urlencode("USD");
$Dallor = "hl=en&q=$amount$from_GBP0%3D%3F$to_usd";
$US_Rate = file_get_contents("http://google.com/ig/calculator?".$Dallor);
$US_data = explode('"', $US_Rate);
$US_data = explode(' ', $US_data['3']);
$var_USD = $US_data['0'];
echo $to_usd;
echo $var_USD;
echo '<br/>'; 
?>

Google currency rates are not accurate google itself says ==> Google cannot guarantee the accuracy of the exchange rates used by the calculator. You should confirm current rates before making any transactions that could be affected by changes in the exchange rates. Foreign currency rates provided by Citibank N.A. are displayed under licence. Rates are for information purposes only and are subject to change without notice. Rates for actual transactions may vary and Citibank is not offering to enter into any transaction at any rate displayed.

对于所有寻找有关货币兑换提示的新手,请查看此链接。 Datavoila

它对我自己的 C# 项目帮助很大。以防万一该网站消失,我将添加下面的代码。只需将以下步骤添加到您自己的项目中即可。抱歉格式问题。

const string fromCurrency = "USD";
const string toCurrency = "EUR";
const double amount = 49.95;
// For other currency symbols see http://finance.yahoo.com/currency-converter/
// Clear the output editor //optional use, AFAIK
Output.Clear();

// Construct URL to query the Yahoo! Finance API
const string urlPattern = "http://finance.yahoo.com/d/quotes.csv?s={0}{1}=X&f=l1";
string url = String.Format(urlPattern, fromCurrency, toCurrency);

// Get response as string
string response = new WebClient().DownloadString(url);

// Convert string to number
double exchangeRate =
    double.Parse(response, System.Globalization.CultureInfo.InvariantCulture);

// Output the result
Output.Text = String.Format("{0} {1} = {2} {3}",
                            amount, fromCurrency,
                            amount * exchangeRate, toCurrency);

For all newbie guys searching for some hint about currency conversion, take a look at this link. Datavoila

It helped med a lot regarding my own project in C#. Just in case the site disappears, I'll add the code below. Just add the below steps to your own project. Sorry about the formatting.

const string fromCurrency = "USD";
const string toCurrency = "EUR";
const double amount = 49.95;
// For other currency symbols see http://finance.yahoo.com/currency-converter/
// Clear the output editor //optional use, AFAIK
Output.Clear();

// Construct URL to query the Yahoo! Finance API
const string urlPattern = "http://finance.yahoo.com/d/quotes.csv?s={0}{1}=X&f=l1";
string url = String.Format(urlPattern, fromCurrency, toCurrency);

// Get response as string
string response = new WebClient().DownloadString(url);

// Convert string to number
double exchangeRate =
    double.Parse(response, System.Globalization.CultureInfo.InvariantCulture);

// Output the result
Output.Text = String.Format("{0} {1} = {2} {3}",
                            amount, fromCurrency,
                            amount * exchangeRate, toCurrency);
