需要有关 CyberSource 身份验证的帮助

Question

我正在尝试 post 对 "flex/v1/keys" api 的请求，并且我正在尝试反映 CyberSource 在 api 页面上的示例。但我一直回来 {"response":{"rmsg":"Authentication Failed"}} 。请有人帮助我，我一无所知，现在已经挣扎了一段时间。

用于 headers 排序的代码。

var crypto = require("crypto-js");
var requestHost = 'apitest.cybersource.com';
var merchantId = 'testrest';
var merchantKeyId = '08c94330-f618-42a3-b09d-e1e43be5efda';
var merchantSecretKey = 'yBJxy6LjM2TmcPGu+GaJrHtkke25fPpUX+UY6/L/1tE=';
var resource = "/flex/v1/keys";

//digest
var payload = '{"encryptionType": "None"}';
var data = crypto.enc.Utf8.parse(payload)
var hash = crypto.SHA256(data)
var base64 = crypto.enc.Base64.stringify(hash);
var digest = "SHA-256=" + base64;
pm.globals.set("digest",digest);

//date
var date = new Date(Date.now()).toUTCString();
pm.globals.set("date",date);

//signature
var signatureHeader = "";
signatureHeader += "keyid=\"" + merchantKeyId + "\"";
signatureHeader += ", algorithm=\"HmacSHA256\"";
var headersForPostMethod = "host date (request-target) digest v-c-merchant-id";
signatureHeader += ", headers=\"" + headersForPostMethod + "\"";

var signatureString = 'host: ' + requestHost;
signatureString += '\ndate: ' + new Date(Date.now()).toUTCString();
signatureString += '\n(request-target): ';
var targetUrlForPost = "post " + resource;
signatureString += targetUrlForPost + '\n';
signatureString += 'digest: SHA-256=' + digest + '\n';
signatureString += 'v-c-merchant-id: ' + merchantId;

var dataSigString = crypto.enc.Utf8.parse(signatureString);
var secKey = crypto.enc.Base64.parse(merchantSecretKey);
var hashHmac = CryptoJS.HmacSHA256(dataSigString, secKey)
var base64hashHmac = CryptoJS.enc.Base64.stringify(hashHmac);

signatureHeader += ", signature=\"" + base64hashHmac + "\"";
pm.globals.set("signature",signatureHeader);

我正在尝试发送我的 post 请求。

curl --location --request POST 'https://apitest.cybersource.com/flex/v1/keys' \
--header 'digest: SHA-256=yF79QR9XHmXEMjhnXRIvsaGie/xoTduWMP8kMOUIyVc=' \
--header 'v-c-merchant-id: testrest' \
--header 'date: Fri, 29 May 2020 15:06:42 GMT' \
--header 'host: apitest.cybersource.com' \
--header 'signature: keyid="08c94330-f618-42a3-b09d-e1e43be5efda", algorithm="HmacSHA256", headers="host date (request-target) digest v-c-merchant-id", signature="lnv5/zeUimcef0Dr3VeOyKgOw/cX8Erdb+qaKuSwuug="' \
--header 'profile-id: 93B32398-AD51-4CC2-A682-EA3E93614EB1' \
--header 'Content-Type: application/json' \
--data-raw '{"encryptionType": "None"}'

结果

Answer 1

对于遇到此问题的任何人，我已经找到了我的修复程序，它现在可以与 crypto-js 身份验证一起使用。

我犯了一个愚蠢的错误，没有正确构建字符串。只需使用以下内容更新我的问题中提到的脚本。

损坏

signatureString += 'digest: SHA-256=' + digest + '\n';

修复

signatureString += 'digest: ' + digest + '\n';
