Bittrex返回APIKEY_NOT_PROVIDED

Question

我试图在我的示例iOS应用程序中调用Bittrex。

我收到了以下信息。

返回消息

SUCCESS: {
    message = "APIKEY_NOT_PROVIDED";
    result = "<null>";
    success = 0;
}

我检查了HTTP请求，每个was如下所示。

API请求

$ curl -i \
    -b "__cfduid=dea9a55b977dded0f94ad14f7158f03e91497078592" \
    -H "Content-Type: application/json" \
    -H "Accept-Language: en;q=1.0" \
    -H "apisign: 41a5b3a98d7da9bee01ddb8ab72dee...." \
    -H "User-Agent: SampleApp/1.0 (com.sampleapp.SampleApp; build:1; iOS 10.3.1) Alamofire/4.4.0" \
    -H "Accept-Encoding: gzip;q=1.0, compress;q=0.5" \
    -d "{\"apikey\":\"f23439b...\",\"nonce\":\"1497703898.0\"}" \
"https://bittrex.com/api/v1.1/account/getbalances"

我的代码如下所示。

码

let timeInterval = NSDate().timeIntervalSince1970
let epochtime = String(floor(timeInterval))
let parameters = "apikey=" + "f23439b..." + "&" + "nonce=" + epochtime
let url = path + "getbalances" + "?" + parameters
let secretKey: String = "df8a62...".hmac(algorithm: CryptoAlgorithm.SHA512, key: url)

Alamofire.request(path + "getbalances", 
                  method: .get, 
                  parameters: ["apikey":"f23439b...", "nonce":epochtime], 
                  encoding: JSONEncoding.default, 
                  headers: ["apisign":secretKey])
    .responseJSON(completionHandler: { response in
        let json = response.result.value as! NSDictionary
        let success = json["success"] as! CFBoolean
        if (success == kCFBooleanTrue) {
            //do something
            print(json)
        } else {
            let reason = response.result.description as AnyObject
            print(reason)
        }
    })

Answer 1

我相信您对新的V1.1 API有问题，您需要用HMAC- the 512加密秘密：

对于这个版本，我们使用标准的HMAC-HMAC 512签名。将apikey和nonce附加到请求中，并计算HMAC哈希，并将其包含在apisign头下。注:现在不受尊重，但以后会强制执行。

不是iOS专家，但这可能会帮助您：

$apikey='xxx';
$apisecret='xxx';
$nonce=time();
$uri='https://bittrex.com/api/v1.1/market/getopenorders?apikey='.$apikey.'&nonce='.$nonce;
$sign=hash_hmac('sha512',$uri,$apisecret);
$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('apisign:'.$sign));
$execResult = curl_exec($ch);
$obj = json_decode($execResult);

Answer 2

看起来是一个简单的错误/您应该使用api秘密，并且我认为字符串的预设应该是uri(而不是url)。有一个使用Crypro库的快速BittrexKit库--方法签名略有不同。

let secretKey: String = URI.hmac(algorithm: CryptoAlgorithm.SHA512, key: APISECRET)

从https://github.com/yuzushioh/BittrexKit摘樱桃

import Crypto

    guard let sign = HMAC.sign(message: uri, algorithm: .sha512, key: auth.apiSecret) else {
        print("Bittrex: HMAC failed")
    }



  private func buildURI() -> String? {
    let url = path.isEmpty ? baseURL : baseURL.appendingPathComponent(path)

    guard var components = URLComponents(url: url, resolvingAgainstBaseURL: true) else {
        return nil
    }

    if let queryParameters = queryParameters, !queryParameters.isEmpty {
        components.percentEncodedQuery = URLEncodedSerialization.string(from: queryParameters)
    }

    guard let uri = components.url?.absoluteString else {
        return nil
    }

    return uri
  }

(如果有人在使用alamofire进行这方面的工作，我欢迎任何编辑。)
