通过MtGox的Streaming API进行身份validation的命令

我正在使用nodejs和socket.io-client连接到这里描述的MtGox Streaming API： https ://en.bitcoin.it/wiki/MtGox/API/Streaming#Authenticated_commands

这些例子是用PHP编写的，我尽我所能将它们转换成JS，但我一直得到服务器的响应“无效的调用”

var sec_key_buffer = Buffer(secret_key, 'base64'); var hmac = crypto.createHmac('sha512', sec_key_buffer); var nonce = Date.now() + ""; var id = crypto.createHash('md5').update(nonce).digest('hex'); var query = { "call": 'private/info', "id": id, "nonce": nonce }; var body = JSON.stringify(query); var sign = hmac.update(body).digest('binary'); // The 'api_key' field has already stripped of the '-' character var callBody = new Buffer(api_key + sign + body).toString('base64'); // 'connection' is the socket.io connection to 'https://socketio.mtgox.com/mtgox' connection.json.send({ "op": "call", "id": id, "call": callBody, "context": 'mtgox.com' }); 

任何帮助，将不胜感激。

这是什么似乎为我工作：

 var io = require('socket.io-client'); var crypto = require('crypto'); var socket = io.connect('https://socketio.mtgox.com/mtgox'); var MTGOX_API_INFO = { key: '<YOUR_KEY>', secret: '<YOUR_SECRET>' } var MTGOX_CHANNELS = { trade: 'dbf1dee9-4f2e-4a08-8cb7-748919a71b21', depth: '24e67e0d-1cad-4cc0-9e7a-f8523ef460fe', ticker: 'd5f06780-30a8-4a48-a2f8-7ed181b4a13f' } // unsubscribe from depth and trade messages socket.emit('message', { op: 'unsubscribe', channel: MTGOX_CHANNELS.trade }); socket.emit('message', { op: 'unsubscribe', channel: MTGOX_CHANNELS.depth }); socket.emit('message', { op: 'unsubscribe', channel: MTGOX_CHANNELS.ticker }); var getNonce = function() { return ((new Date()).getTime() * 1000).toString(); } var nonce = getNonce(); var requestId = crypto.createHash('md5').update(nonce).digest('hex'); var query = { id: requestId, call: 'private/info', nonce: nonce // params: {}, // item: 'BTC', // currency: 'USD' }; var queryJSON = JSON.stringify(query); var signedQuery = crypto.createHmac('sha512', new Buffer(MTGOX_API_INFO.secret, 'base64')).update(queryJSON).digest('binary'); var binKey = (new Buffer(MTGOX_API_INFO.key.replace(/-/g, ''), 'hex')).toString('binary'); var buffer = new Buffer(binKey + signedQuery + queryJSON, 'binary'); var call = buffer.toString('base64'); var command = { op: 'call', id: requestId, call: call, context: 'mtgox.com' }; console.log("REQUEST:", command); socket.emit('message', command); socket.on('message', function(data) { console.log(data); }); 

更新：我也抽象成一个简单的节点模块 。

在添加散列和消息内容之前，必须将api密钥解码为原始字节。

不太熟悉node.js来提供代码，但在Java（使用番石榴）它是：

 byte[] apiKey = BaseEncoding.base16().lowerCase().decode(API_KEY.replace("-", ""));
