C# 在请求头中添加JsessionID

我已经得到了Jsessionid，我想将它添加到标题中，但我不知道在哪里添加它

Cookie jSessionID = client.ResponseCookies["JSESSIONID"];

      if (jSessionID != null)
       {
         // JSESSIONID
         sessionid = jSessionID.Value;

        var settings = new ODataClientSettings()
        {
            UrlBase = "MyURL" 
        };

        settings.BeforeRequest += delegate(HttpRequestMessage request)
        {
          String aux = String.Join(":", new String[] {"admin", "admin" });
          var plainTextBytes = System.Text.Encoding.UTF8.GetBytes(aux);
          request.Headers.Add("Authorization", "Basic " + System.Convert.ToBase64String(plainTextBytes));
        };
        var client2 = new ODataClient(settings);
     }

以下代码显示了如何向Simple.OData.Client添加其他头：

var settings = new ODataClientSettings {UrlBase = "http://localhost/odata"};
settings.BeforeRequest += x =>
{
    x.Headers.Add("context", "test");
};

var client = new ODataClient(settings);

所以基本上你做对了。有什么不起作用的吗？能否跟踪HTTP通信并检查是否设置了标头
