【问题描述】:
我如何订购期货?我收到两个错误:“未发送所需的时间戳参数,为空/null,或格式不正确。”或“此请求的签名无效。”
public static async void Order()
{
string base_uri = "https://fapi.binance.com/fapi/v1/order?";
string API_Key = "bSQQlu2k5tf0oSUGZsNGptisIxXLux8wb............................";
string Secret_Key = "gWPKP66geFL0ryijnlU3TTepS61.............................";
string symbol = "XRPUSDT";
string side = "BUY";
string type = "MARKET";
string timeInForce = "GTC";
decimal quantity = 20;
long recvWindow = 5000;
long timestamp = GetServerTime();
string queryString = "symbol=" + symbol + "&side=" + side + "type=" + type + "&timeInForce=" + timeInForce;
string signature = HMACHASH(queryString, Secret_Key);
var Payload = new Credentials
{
Quantity = quantity,
RecvWindow = recvWindow,
Timestamp = timestamp,
Signature = signature
};
var stringPayload = JsonConvert.SerializeObject(Payload);
var httpContent = new StringContent(stringPayload, Encoding.UTF8, "application/json");
httpContent.Headers.Add("X-MBX-APIKEY", API_Key);
using (var httpClient = new HttpClient())
{
var httpResponse = await httpClient.PostAsync(base_uri + queryString, httpContent);
if (httpResponse.Content != null)
{
var responseContent = await httpResponse.Content.ReadAsStringAsync();
Console.WriteLine(responseContent);
}
}
}
这就是我获取时间戳的方式
public static long GetServerTime()
{
string str = BinanceResponse("https://fapi.binance.com/fapi/v1/time");
string[] arr = str.Split('\"');
str = arr[2].Trim(':', '}');
return long.Parse(str);
}
凭证类
internal class Credentials
{
[JsonProperty("quantity")]
public decimal Quantity { get; set; }
[JsonProperty("recvWindow")]
public long RecvWindow { get; set; }
[JsonProperty("timestamp")]
public long Timestamp { get; set; }
[JsonProperty("signature")]
public string Signature { get; set; }
}
序列化后
stringPayload = "{"quantity":20.0,"recvWindow":5000,"timestamp":1625061703897,"signature":"2794e66d4e5b5b6338782e058747a567db523.........................."}"
如果我这样尝试:
string queryString = "symbol=" + symbol + "&side=" + side + "&type=" + type +
"&timeInForce=" + timeInForce + "&quantity=" + quantity + "&recvWindow=" +
recvWindow + "×tamp=" + timestamp;
string signature = HMACHASH(queryString, Secret_Key);
queryString += "&signature=" + signature;
错误:“此请求的签名无效。”
已解决! 谢谢你们!我使用了 Fiddler,发现 type = "MARKET" 不需要 "timeInForce" 参数。所有的问题都是因为他。
string queryString = "symbol=" + symbol + "&side=" + side + "&type=" + type +
̶"̶&̶t̶i̶m̶e̶I̶n̶F̶o̶r̶c̶e̶=̶"̶ ̶+̶ ̶t̶i̶m̶e̶I̶n̶F̶o̶r̶c̶e̶ + "&quantity=" + quantity + "&recvWindow=" +
recvWindow + "×tamp=" + timestamp;
【问题讨论】:
-
GetServerTime()返回什么?DateTime对象? -
GetServerTime() 长返回
