Coinbase Pro API 无效签名 ColdFusion

如何解决Coinbase Pro API 无效签名 ColdFusion

我试图从 Coinbase Pro 获取简单的帐户信息，但似乎无法弄清楚 CB-ACCESS-SIGN 标头。我不断收到“无效签名”消息。

来自 Coinbase Pro API 文档：

CB-ACCESS-SIGN 标头是通过使用以下方法创建 sha256 HMAC 生成的 prehash 字符串时间戳 + 方法上的 base64 解码密钥

• requestPath + body（其中 + 表示字符串连接）并对输出进行 base64 编码。时间戳值与 CB-ACCESS-TIMESTAMP 标头。

body为请求正文字符串，无请求时省略 正文（通常用于 GET 请求）。

方法应该是大写。

我的代码：

    <cfscript>
        
        accessKey = 'xxx';
        
        passphrase = 'yyy';
        
        theSecret = 'zzz';
        
        // create an epoch time stamp
        theTime = Now();
        utcTime = dateConvert('local2UTC',theTime);
        ISOtimeStamp = dateFormat(utcTime,"yyyy-mm-dd")&"T"&timeFormat(utcTime,"HH:mm:ss")&".761Z";
        timeStamp = numberFormat(dateDiff("s","January 1 1970 00:00",ISOtimeStamp) + 28800.761,"_.000");
        
        requestPath = '/accounts';
        
        theBody = "";
        
        method = "GET";
    
    
        // create the prehash string by concatenating required parts
        what = '#timeStamp#' & '#method#' & '#requestPath#' & '#theBody#';
        
        // decode the base64 secret
        theKey = binaryDecode(theSecret,"base64");
        
        // create s sha256 hmac with the key
        theHmac = hmac("#what#","#theKey#","HMACSHA256");
        
        // encode the result
        cas = toBase64(theHmac);
        
        
    </cfscript>
