如何使用秘密密钥从KeyVault取得凭证？

Question

我有一个密钥库，该密钥库使用秘密密钥检索javascript中的凭据。但是我的客户不想使用“ VaultSettings.KeyVaultSettings.azureKeyVaultAccessKey”，这是在密钥库门户中注册的应用程序的秘密值。 以下是用于访问凭据的代码。

C＃AzureServiceTokenProvider（）中提供了一种方法，该方法提供可用于访问keyVault中的凭据的令牌。我们在node.js中有类似的东西吗？

const AuthenticationContext = require('adal-node').AuthenticationContext;
let VaultSettings = require('./KeyVaultSettings');

class KeyVaultUtils {
    constructor(secretNameIdentifier, secretVersionIdentifier) {
            this.secretName = secretNameIdentifier;
            this.secretVersion = secretVersionIdentifier;
    }

    authenticator(challenge, callback) {
            var context = new AuthenticationContext(challenge.authorization);
            return context.acquireTokenWithClientCredentials(challenge.resource,
                VaultSettings.KeyVaultSettings.clientAppId,
                VaultSettings.KeyVaultSettings.azureKeyVaultAccessKey,
                function (err, tokenResponse) {
                if (err) throw err;
                    var authorizationValue = tokenResponse.tokenType + ' ' + tokenResponse.accessToken;
                    return callback(null, authorizationValue);
                });
        }

        getKeyVaultValue(callback) {
            var credentials = new KeyVault.KeyVaultCredentials(this.authenticator);
            var client = new KeyVault.KeyVaultClient(credentials);
            client.getSecret(VaultSettings.KeyVaultSettings.vaultUri, VaultSettings.KeyVaultSettings.azureAccount, VaultSettings.KeyVaultSettings.azureAccountKey)
                .then(function (result) {
                callback(result);
            });
        };
}
module.exports = { KeyVaultUtils };```
