根据401错误，表示令牌无效。

使用以下代码生成正确的SAS令牌，然后将生成的令牌传递给 Authorization 标头：

using System;
using System.Globalization;
using System.Security.Cryptography;
using System.Text;
using System.Web;

namespace App1
{
    class Program
    {
        static readonly string queueUrl = "TODO"; // Format: "https://<service bus namespace>.servicebus.windows.net/<queue name>";
        static readonly string signatureKeyName = "TODO";
        static readonly string signatureKey = "TODO";
        static readonly TimeSpan timeToLive = TimeSpan.FromDays(1);
        static void Main(string[] args)
        {
            var token = GetSasToken(queueUrl,signatureKeyName,signatureKey,timeToLive);
            Console.WriteLine("Authorization: " + token);
            Console.WriteLine("Press any key to exit.");
            Console.ReadLine();
        }
        public static string GetSasToken(string resourceUri,string keyName,string key,TimeSpan ttl)
        {
            var expiry = GetExpiry(ttl);
            string stringToSign = HttpUtility.UrlEncode(resourceUri) + "\n" + expiry;
            HMACSHA256 hmac = new HMACSHA256(Encoding.UTF8.GetBytes(key));
            var signature = Convert.ToBase64String(hmac.ComputeHash(Encoding.UTF8.GetBytes(stringToSign)));
            var sasToken = String.Format(CultureInfo.InvariantCulture,"SharedAccessSignature sr={0}&sig={1}&se={2}&skn={3}",HttpUtility.UrlEncode(resourceUri),HttpUtility.UrlEncode(signature),expiry,keyName);
            return sasToken;
        }

        private static string GetExpiry(TimeSpan ttl)
        {
            TimeSpan expirySinceEpoch = DateTime.UtcNow - new DateTime(1970,1,1) + ttl;
            return Convert.ToString((int)expirySinceEpoch.TotalSeconds);
        }
    }
}
