Request相关的参数。 需要在Program.cs 注入IHttpContextAccessor

 //Below services used to get tokenservices.AddHttpContextAccessor();services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

public string GetClientIpAddress(){var clientIp = _httpContextAccessor?.HttpContext?.Connection?.RemoteIpAddress?.ToString();return clientIp!;}public string GetBrowserInfo(){var browserInfo = _httpContextAccessor?.HttpContext?.Request?.Headers["User-Agent"].ToString();return string.IsNullOrEmpty(browserInfo) ? string.Empty : browserInfo;}public string GetMethodName(){var url = _httpContextAccessor?.HttpContext?.Request.Path;return string.IsNullOrEmpty(url) ? string.Empty : url;}public string GetParametersInfo(){var parameter = string.Empty;try{var request = _httpContextAccessor?.HttpContext?.Request;if (request != null){var methond = request.Method;Dictionary<string, object> keyValuePairs = new Dictionary<string, object>();if (methond == "GET"){if (request.Query != null && request.Query.Count() > 0){foreach (var item in request.Query){keyValuePairs.Add(item.Key, item.Value);}parameter = JsonConvert.SerializeObject(keyValuePairs);}}else{if (request.HasFormContentType){//For Upload documentsif (request.Form.Keys != null){foreach (var itemFormKey in request.Form.Keys){keyValuePairs.Add(itemFormKey, request.Form[itemFormKey]);}}if (request.Form.Files != null && request.Form.Files.Count() > 0){keyValuePairs.Add($"Attachments-{Guid.NewGuid()}", string.Join("; ", request.Form.Files.Select(x => x.FileName)));}parameter = JsonConvert.SerializeObject(keyValuePairs);}else if (request.Query != null && request.Query.Count() > 0){foreach (var item in request.Query){keyValuePairs.Add(item.Key, item.Value);}parameter = JsonConvert.SerializeObject(keyValuePairs);}if (request.HasJsonContentType()){var rawMessage = GetRawBodyAsync(request).Result;parameter += rawMessage;}}}}catch (Exception ex){parameter = ex.Message;Log.Error(ex, $"GetParametersInfo failed. {ex.Message}");}return parameter;}

 Use Middleware

    /// <summary>/// Web API Audit Trail and Exception Result handler/// </summary>public static class ApplicationBuilderExtensions{/// <summary>/// Web API Audit Trail and Exception Result handler/// </summary>/// <param name="applicationBuilder"></param>/// <returns></returns>public static IApplicationBuilder UseGlobalRequestHandling(this IApplicationBuilder applicationBuilder)=> applicationBuilder.UseMiddleware<GlobalRequestHandlingMiddleware>();}

Register in Program.cs

         //Below services used to get tokenservices.AddHttpContextAccessor();services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();services.AddSingleton<IPrincipalAccessor, PrincipalAccessor>();app.UseGlobalRequestHandling();//add Global Resust HandlingMiddleware
