使用dotnetcore HttpClient复制特定证书cURL

Question

我正在尝试在dotnetcore中复制curl命令以连接到kubernetes集群（从内部）。

以下curl命令有效。 curl -v --cacert /var/run/secrets/kubernetes.io/serviceaccount/ca.crt -H "Authorization: Bearer $(cat /var/run/secrets/kubernetes.io/serviceaccount/token)" https://kubernetes/

这是我尝试使用HttpClient

重新创建此内容

private HttpClient GetClient()
{
    const string certPath = "/var/run/secrets/kubernetes.io/serviceaccount/ca.crt";
    const string tokenPath = "/var/run/secrets/kubernetes.io/serviceaccount/token";
    const string baseAddress = "https://kubernetes";
    var handler = new HttpClientHandler
    {
        ClientCertificateOptions = ClientCertificateOption.Manual,
        SslProtocols = SslProtocols.Tls12
    };
    handler.ClientCertificates.Add(
       new X509Certificate2(certPath));

    var token = File.ReadAllText(tokenPath);
    var httpClient = new HttpClient(handler)
    {
        BaseAddress = baseAddress,
        DefaultRequestHeaders =
        {
            {"Authorization", $"Bearer {token}"}
        }
    };
    return httpClient;
}

public void Test()
{
    var client = GetClient();
    var result = client.GetStringAsync("/").GetAwaiter().GetResult();
    Console.WriteLine(result);
}

异常并不是太有用，而且我不确定我在哪里错误配置我的HttpClient。

这是例外细节
