根据this主题我正在使用这段代码

public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request,  System.ServiceModel.IClientChannel channel)
{
    HttpRequestMessageProperty httpRequestMessage;
    object httpRequestMessageObject;
    if (request.Properties.TryGetValue(HttpRequestMessageProperty.Name, out httpRequestMessageObject))
    {
        httpRequestMessage = httpRequestMessageObject as HttpRequestMessageProperty;
        if (string.IsNullOrEmpty(httpRequestMessage.Headers[USER_AGENT_HTTP_HEADER]))
        {
            httpRequestMessage.Headers[USER_AGENT_HTTP_HEADER] = this.m_userAgent;
        }
    }
    else
    {
        httpRequestMessage = new HttpRequestMessageProperty();
        requestMessageProperty.Headers.Add("Authorization",  token);
        request.Properties.Add(HttpRequestMessageProperty.Name, httpRequestMessage);
    }

但不幸是，自从我将代码从. netframwork4.7移到. netcore2.1项目后，我得到了以下错误代码：
未能将值为“qqqqqqqqq=”的HTTP标头“Authorization”复制到“System.Net.Http.Headers. HttpRequestHeaders”。\r\n值“qqqqqqqqq=”的格式无效。
在旧项目中，一切正常，是否可以跳过授权标题验证？谢谢
