大家好,我在 swift 3 交易应用程序中写的每一个人。我只有 3 个命令 buy sell 和 cancel 有问题,那些会导致 error = "Invalid API key/secret pair."; 其他类似 returnOpenOrders , returnTradehistory returnBalances 工作正常并返回正确的值。

那就是可能请求功能:

func getRawJSON(paramss:[String : Any]){
    var paramss1:[String:Any] = [:]
    let APIURL = "https://poloniex.com/tradingApi"
    let timeNowInt = Int(NSDate().timeIntervalSince1970 ) * 10000000

    var zdanie2:String! = ""

for (x,y) in paramss{

                        paramss1[x]=y

                        }
    paramss1["nonce"]=timeNowInt


for (x,y) in paramss{
    if (zdanie2 == "")
    {zdanie2="\(x)=\(y)"
    }
    else
    {
        zdanie2=zdanie2+"&"+"\(x)=\(y)"
    }

}

zdanie2=zdanie2+"&nonce=\(timeNowInt)"



    let array: [UInt8] = Array(zdanie2.utf8)

    let hmac: Array<UInt8> = try! HMAC(key: secretKey!.utf8.map({$0}), variant: .sha512).authenticate(array)
    let hmacData = Data(bytes: hmac).toHexString()
       let headers  = ["Key": publicKey!,"Sign": hmacData] as   [String : String]


    request(APIURL,method: .post,parameters: paramss1,headers:headers).responseJSON {
        response in
        print(response)
       print(response.request)


    }

}

这是我的买/卖功能:

 func buy(currencyPair:String,rate:Double,amount:Double){
    return self.getRawJSON( paramss: ["command":"buy","currencyPair":currencyPair,"rate":rate ,"amount":amount])
}
func sell(currencyPair:String,rate:Double,amount:Double){
    return self.getRawJSON( paramss: ["command":"sell","currencyPair":currencyPair,"rate": rate ,"amount":amount])
}

标头参数(var paramss1)的输出是:

[“金额”:2.0,“命令”:“卖出”,“随机数”:15308121310000000,“货币对”:“BTC_XRP”,“汇率”:7.6000000000000004e-05]

符号数组是:

金额=2.0&command=sell¤cyPair=BTC_XRP&rate=7.6e-05&nonce=15308121310000000

我真的不知道出了什么问题你能帮忙解决这个问题吗?

费率值无效。

rate 和 amount 值必须类似于 1、1.1、1.00000001。

无效请求: 金额=2.0&command=sell¤cyPair=BTC_XRP& rate=7.6e-05 &nonce=15308121310000000

有效请求: command=sell&amount=2.0&¤cyPair=BTC_XRP&rate=7.000006&nonce=15308121310000000
