.netcore2.1 添加Action接口请求全局日志打印filter

 

• 添加过滤器

　　

using Microsoft.AspNetCore.Http.Internal;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Filters;
using Microsoft.Extensions.Logging;
using Newtonsoft.Json;
using System.IO;
using System.Text;

namespace MyPro.Filters
{
    public class LogFilter : IActionFilter
    {
        ILogger _logger;
        public LogFilter(ILogger<LogFilter> logger)
        {
            _logger = logger;
        }
        public void OnActionExecuted(ActionExecutedContext context)
        {
            if (!(context.Result is FileStreamResult))
            {
                var statusCode = context.HttpContext.Response.StatusCode;
                var result = context.Result;
                _logger.LogInformation($"HashCode:{context.HttpContext.Request.GetHashCode()},路由:{context.HttpContext.Request.Path},响应码{statusCode},出参{JsonConvert.SerializeObject(result)}");
            }
        }

        public void OnActionExecuting(ActionExecutingContext context)
        {
            if (context.HttpContext.Request.Path != null && !context.HttpContext.Request.Path.Value.ToLower().Contains("/user/login"))
            {
                var header = context.HttpContext.Request.Headers;
                var query = context.HttpContext.Request.Query;
                var body = string.Empty;
                if (context.HttpContext.Request.Method.ToUpper() == "POST")
                {

                    context.HttpContext.Request.EnableRewind();
                    context.HttpContext.Request.Body.Seek(0, 0);
                    using (var ms = new MemoryStream())
                    {
                        context.HttpContext.Request.Body.CopyTo(ms);
                        var b = ms.ToArray();
                        body = Encoding.UTF8.GetString(b);
                    }
                }
                var log = new { query, header, body };
                _logger.LogInformation($"HashCode:{context.HttpContext.Request.GetHashCode()},路由:{context.HttpContext.Request.Path},入参{JsonConvert.SerializeObject(log)}");
            }
        }
    }
}

 

• 在Startup.cs中注入服务

  services.AddMvc(options =>
            {
                options.Filters.Add(typeof(LogFilter));
              
            }).SetCompatibilityVersion(CompatibilityVersion.Version_2_1).AddJsonOptions(options =>
            {
                options.SerializerSettings.DateFormatString = "yyyy-MM-dd HH:mm:ss";
            });
