Angular4/Typescript標誌Kraken API調用（CryptoJS）

Question

我想從我的Agnular4項目調用Kraken API。我正在使用crypto-js庫https://www.npmjs.com/package/crypto-js。

海妖需要此簽名：

API-Sign = Message signature using HMAC-SHA512 of (URI path + SHA256(nonce + POST data)) and base64 decoded secret API key 

Correct result: 
gy+Ljq8nPD2kFFCQSofQ46pbPV8z8D7klrU78Kxvl6jyior/Ev2FiclhKs+zoqrmL8u8u1Y9CXzIw0n3CswtNA== 

Result from: 
CryptoJS.HmacSHA512(path + CryptoJS.enc.Hex.stringify(hashDigest), secret);

我以前做這些調用了Android應用的，它的工作（見代碼，並在文章底部的結果）。

我也嘗試了很多東西好幾天。我可能已經做了一個愚蠢的錯誤：d

預先感謝閱讀，希望回答這個:)

這裏是我的Angular4客戶端代碼：

import * as CryptoJS from 'crypto-js'; 
... 
this.API_SECRET = "0a...g=="; 
... 
private getMessageSignature(path: string, request: string, nonce: number) { 
    console.log('getMessageSignature', path, request, nonce); 
    console.log('request', request); 
    const message = nonce + request; 
    var secret = CryptoJS.enc.Base64.parse(this.API_SECRET); 
    var hashDigest = CryptoJS.SHA256(message); 
    var hashDigestBase64 = CryptoJS.enc.Base64.stringify(hashDigest); 
    console.log('hashDigest', CryptoJS.enc.Base64.stringify(hashDigest)); // correct 
    console.log('hashDigest', CryptoJS.enc.Hex.stringify(hashDigest)); // correct 

    var hmacDigest = CryptoJS.HmacSHA512(path + hashDigest, secret); 
    console.log('hmacDigest', CryptoJS.enc.Base64.stringify(hmacDigest)); 
    var hmacDigest1 = CryptoJS.HmacSHA512(path + CryptoJS.enc.Base64.stringify(hashDigest), secret); 
    console.log('hmacDigest1', CryptoJS.enc.Base64.stringify(hmacDigest1)); 
    var hmacDigest2 = CryptoJS.HmacSHA512(path + CryptoJS.enc.Hex.stringify(hashDigest), secret); 
    console.log('hmacDigest2', CryptoJS.enc.Base64.stringify(hmacDigest2)); 
    var hmacDigest3 = CryptoJS.HmacSHA512(path + CryptoJS.enc.Latin1.stringify(hashDigest), secret); 
    console.log('hmacDigest3', CryptoJS.enc.Base64.stringify(hmacDigest3)); 

    var hmacDigest4 = CryptoJS.HmacSHA512(path + hashDigest, this.API_SECRET); 
    console.log('hmacDigest4', CryptoJS.enc.Base64.stringify(hmacDigest4)); 
    var hmacDigest5 = CryptoJS.HmacSHA512(path + CryptoJS.enc.Base64.stringify(hashDigest), this.API_SECRET); 
    console.log('hmacDigest5', CryptoJS.enc.Base64.stringify(hmacDigest5)); 
    var hmacDigest6 = CryptoJS.HmacSHA512(path + CryptoJS.enc.Hex.stringify(hashDigest), this.API_SECRET); 
    console.log('hmacDigest6', CryptoJS.enc.Base64.stringify(hmacDigest6)); 
    var hmacDigest7 = CryptoJS.HmacSHA512(path + CryptoJS.enc.Latin1.stringify(hashDigest), this.API_SECRET); 
    console.log('hmacDigest7', CryptoJS.enc.Base64.stringify(hmacDigest7)); 

    return CryptoJS.enc.Base64.stringify(hmacDigest); 
} 

Angular4結果：

Android代碼：

private static String calculateSignature(String nonce, String data, String path) { 
    System.out.println("calculateSignature " + nonce + " " + data + " " + path); 
    String signature = ""; 
    try { 
     MessageDigest md = MessageDigest.getInstance("SHA-256"); 
     md.update((nonce + data).getBytes()); 
     Mac mac = Mac.getInstance("HmacSHA512"); 
     mac.init(new SecretKeySpec(Base64.decode(API_SECRET.getBytes(), Base64.NO_WRAP), "HmacSHA512")); 
     mac.update(path.getBytes()); 
     byte[] digest = md.digest(); 
     System.out.println("digest = " + Base64.encodeToString(digest, Base64.NO_WRAP)); 
     signature = Base64.encodeToString(mac.doFinal(digest), Base64.NO_WRAP); 
     System.out.println("signature = " + signature); 
    } catch(Exception e) {} 
    return signature; 
} 

Android的結果：

calculateSignature 1503065538999 nonce=1503065538999 /0/private/Balance 
digest = EcvBaI+IvdvibXZ4UiNlcuAvT8fPPdAItwhBrCNx7q8=

Answer 1

的問題是，由@types/crypto-js提供的方法只包含字符串的方法。

所以我刪除了封裝，可以使用update方法等

private getMessageSignature(apiSecret: string, path: string, request: string, nonce: number) { 
    const secret = CryptoJS.enc.Base64.parse(apiSecret); 
    const hashDigest = CryptoJS.SHA256(nonce + request); 

    const hmac = CryptoJS.algo.HMAC.create(CryptoJS.algo.SHA512, secret); 
    hmac.update(path); 
    hmac.update(hashDigest); 

    return CryptoJS.enc.Base64.stringify(hmac.finalize()); 
}
