401未经授权的API响应，在邮递员身上工作

Question

因此，我正在打一个通话，这使我有一个链接，以稍后再进行另一个接听电话。他们俩在Postman上都很好，但是当我尝试使用RestSharp时，我将在第二个电话中获得401的未经授权。我已经尝试使用HTTPClient和HttpWebrequest，但是我得到了相同的结果。

这是我的代码与RestSharp的样子，

string token = "tokenforbothcalls";
var request = new RestRequest("first/api", Method.Get);
var certfolder = @"C:\folderpath";
var cerFile = Path.Combine(certFolder, "cert.pfx");
var certificate = new X509Certificate2(certFile, "pw", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.PersistKeySet | X509KeyStorageFlags.Exportable);

var clientOptions = new RestClientOptions("https://baseurl.com");
clientOptions.ClientCertificates = new X509CertificateCollection();
clientOptions.ClientCertificates.Add(certificate);

var client = new RestClient(clientOptions);
client.AddDefaultHeader("Authorization", string.Format("Bearer {0}", token));
request.AddHeader("Prefer", "respond-async");

var response = await client.ExecuteAsync(request);

因此可以很好地工作，但是当我接到第二个通话时，我会得到401。

var headers = response.Headers.ToList();
//some more logic to get the link from the first call.

clientOptions = new RestClientOptions("https://baseurl.com");
clientOptions.ClientCertificates = new X509CertificateCollection();
clientOptions.ClientCertificates.Add(certificate);

client = new RestClient(clientOptions);
client.AddDefaultHeader("Authorization", string.Format("Bearer {0}", token));

request = new RestRequest("new/api", Method.Get);

response = await client.ExecuteAsync(request);
