如何查看RestSharp请求(Request)和响应(Response)的原始头部信息(Headers)?

using Newtonsoft.Json;
using RestSharp;

namespace Apis
{
    public abstract class RestApiBase
    {
        protected readonly IRestClient _restClient;
        protected readonly ILogger _logger;

        protected RestApiBase(IRestClient restClient, ILogger logger)
        {
            _restClient = restClient;
            _logger = logger;
        }

        protected virtual IRestResponse Execute(IRestRequest request)

            var stopWatch = new Stopwatch();

            try
            {
                stopWatch.Start();
                response = _restClient.Execute(request);
                stopWatch.Stop();

                // CUSTOM CODE: Do more stuff here if you need to...

                return response;
            }
            catch (Exception e)
            {
                // Handle exceptions in your CUSTOM CODE (restSharp will never throw itself)
            }
            finally
            {
                LogRequest(request, response, stopWatch.ElapsedMilliseconds);
            }

            return null;

                response = _restClient.Execute(request);
                stopWatch.Stop();

                // CUSTOM CODE: Do more stuff here if you need to...

                // We can't use RestSharp deserialization because it could throw, and we need a clean response
                // We need to implement our own deserialization.
                var returnType = JsonConvert.DeserializeObject<T>(response.Content);
                return returnType;
            }
            catch (Exception e)
            {
                // Handle exceptions in your CUSTOM CODE (restSharp will never throw itself)
                // Handle exceptions in deserialization
            }
            finally
            {
                LogRequest(request, response, stopWatch.ElapsedMilliseconds);
            }

            return default(T);
        }

        private void LogRequest(IRestRequest request, IRestResponse response, long durationMs)
        {
            _logger.Trace(() =>
            {
                var requestToLog = new
                {
                    resource = request.Resource,
                    // Parameters are custom anonymous objects in order to have the parameter type as a nice string
                    // otherwise it will just show the enum value
                    parameters = request.Parameters.Select(parameter => new
                    {
                        name = parameter.Name,
                        value = parameter.Value,
                        type = parameter.Type.ToString()
                    }),
                    // ToString() here to have the method as a nice string otherwise it will just show the enum value
                    method = request.Method.ToString(),
                    // This will generate the actual Uri used in the request
                    uri = _restClient.BuildUri(request),
                };

                var responseToLog = new
                {
                    statusCode = response.StatusCode,
                    content = response.Content,
                    headers = response.Headers,
                    // The Uri that actually responded (could be different from the requestUri if a redirection occurred)
                    responseUri = response.ResponseUri,
                    errorMessage = response.ErrorMessage,
                };

                return string.Format("Request completed in {0} ms, Request: {1}, Response: {2}",
                    durationMs, JsonConvert.SerializeObject(requestToLog),
                    JsonConvert.SerializeObject(responseToLog));
            });
        }
    }
}
