我想用JavaScript重新實(shí)現(xiàn)某個(gè)用Python編寫的API客戶端。我無(wú)法復(fù)制 HMAC SHA256 簽名功能。對(duì)于某些鍵，輸出是相同的，但對(duì)于某些鍵，輸出是不同的。在解碼其 Base64 表示后，當(dāng)密鑰由可打印字符組成時(shí)，輸出似乎是相同的。Python#!/usr/bin/env python3import base64import hashlibimport hmacdef sign_string(key_b64, to_sign): key = base64.b64decode(key_b64) signed_hmac_sha256 = hmac.HMAC(key, to_sign.encode(), hashlib.sha256) digest = signed_hmac_sha256.digest() return base64.b64encode(digest).decode()print(sign_string('VGhpcyBpcyBhIHByaW50YWJsZSBzdHJpbmcuCg==', "my message"))print(sign_string('dGhlIHdpbmQgb2YgTXQuIEZ1amkK', "my message"))print(sign_string('pkmNNJw3alrpIBi5t5Pxuym00M211oN86IhLZVT8', "my message"))JavaScript<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/crypto-js.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/hmac-sha256.min.js"></script><script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/enc-base64.min.js"></script><script> function sign_string(key_b64, to_sign) { key = atob(key_b64) var hash = CryptoJS.HmacSHA256(to_sign, key); var hashInBase64 = CryptoJS.enc.Base64.stringify(hash); document.write(hashInBase64 + '<br>'); } sign_string('VGhpcyBpcyBhIHByaW50YWJsZSBzdHJpbmcuCg==', "my message") sign_string('dGhlIHdpbmQgb2YgTXQuIEZ1amkK', "my message") sign_string('pkmNNJw3alrpIBi5t5Pxuym00M211oN86IhLZVT8', "my message")</script>產(chǎn)出PythonTdhfUQfym16HyWQ8wxQeNVvJKr/tp5rLKHYQSpURLpw=pQ5NzK3KIWjqc75AXBvWgLK8X0kZvjRHXrLAdxIN+Bk=8srAvMucCd91CWI7DeCFjxJrEYllaaH63wmVlMk0W+I=JavaScriptTdhfUQfym16HyWQ8wxQeNVvJKr/tp5rLKHYQSpURLpw=pQ5NzK3KIWjqc75AXBvWgLK8X0kZvjRHXrLAdxIN+Bk=31QxOpifnpFUpx/sn336ZmmjkYbLlNrs8NP9om6nPeY=如您所見(jiàn)，前兩個(gè)是相同的，而最后一個(gè)是不同的。如何更改 JavaScript 代碼以使其行為與 python 代碼相同？
