以太坊 获取合约返回值

Last year I got big into Bitcoin; today I own a few dozen bitcoin and am loving my return.  Recently I've been hearing big things about Ethereum, another cryptocurrency.  Ethereum is in its infancy and has recently due to a hack but hey -- at its roughly $10 value now, if it ever hits bitcoin-type heights, you could be in for a great return on investment.  A while back I wrote a few scripts to so I thought I'd repeat that post for getting Ether value!

去年，我热衷于比特币。 今天，我拥有几十个比特币，并且热爱我的回报。 最近，我听到了关于另一种加密货币以太坊的大事。 以太坊处于起步阶段，由于黑客攻击，最近 ，但嘿-以其现在的约10美元的价值，如果它达到了比特币的高度，您可能会获得巨大的投资回报率。 前一阵子我写了一些脚本来所以我想我会重复文章来获得以太价值！

从命令行获取以太值 (Get Ether Value from Command Line)

I use a snippet of python to to grab the value of ether from command line:

我使用一小段python从命令行获取ether的值：

curl -s https://coinmarketcap-nexuist.rhcloud.com/api/eth | python -c "import json, sys; print(json.load(sys.stdin)['price']['usd']")

Since you buy ether with bitcoin, getting its bitcoin value may be more of value:

由于您购买了带有比特币的以太币，因此获取其比特币价值可能更有价值：

curl -s https://coinmarketcap-nexuist.rhcloud.com/api/eth | python -c "import json, sys; print(json.load(sys.stdin)['price']['btc'])"

通过Node.js获得任何价值 (Get Either Value with Node.js)

You can use a library like Request for making the API request but to avoid dependency you can use the base Node.js API:

您可以使用诸如Request之类的库来发出API请求，但为避免依赖，可以使用基本的Node.js API：

var http = require('http');http.get({        host: 'coinmarketcap-nexuist.rhcloud.com',        path: '/api/eth'        },        function(response) {                // Continuously update stream with data                var body = '';                response.on('data', function(d) { body += d; });                response.on('end', function() {                        // Data reception is done, do whatever with it!                        var parsed = JSON.parse(body);                        console.log(parsed.price.usd);                });        });

Cryptocurrency lovers will hate on me for talking about bitcoin and ether in terms of USD dollar price but I still see these cryptocurrencies as a short term investment right now.  Many online stores don't accept bitcoin yet so I don't see a great application right now.  Whatever your reason for wanting to know the price of ether, these scripts will be what you need!

加密货币爱好者会讨厌我谈论以美元价格表示的比特币和以太坊，但我现在仍将这些加密货币视为短期投资。 许多在线商店还不接受比特币，所以我现在看不到一个很好的应用程序。 无论您想知道以太币价格的原因是什么，这些脚本都是您所需要的！
