Question

我试图在我的示例iOS应用程序中调用Bittrex api。

我收到以下消息。

返回消息

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

我检查了HTTP请求，apikey包含在下面。

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"

我的代码就像是。

代码

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)
        }
    })

环境

macOS Sierra
XCode 8.3.3
Swift 3
Alamofire 4.4

Answer 1

我相信您的新V1.1 API存在问题，需要使用HMAC-SHA512加密Secret：

对于此版本，我们使用标准HMAC-SHA512签名。将apikey和nonce附加到您的请求并计算HMAC哈希并将其包含在apisign标头下。注意：nonce目前不受尊重，但稍后会强制执行。

不是iOS专家，但这可能对您有帮助：

$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

看起来像一个简单的错字/你应该使用api秘密和字符串预设我相信应该是uri（不是网址）。有一个快速的BittrexKit库使用Crypro库 - 方法签名略有不同。

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

樱花摘自 https://github.com/yuzushioh/BittrexKit

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
  }

（如果有人使用alamofire进行此操作 - 我欢迎任何修改。）

Bittrex API返回APIKEY_NOT_PROVIDED
