使用ActionFilter记录接口请求日志

实现案例：

https://gitee.com/hgcjd/WebApiFilter

一.首先我们新建一个WebApi项目

开发环境，我们去掉HTTPS配置

二.配置 appsettings.json 文件，配置日志存放路径

{"Logging": {"LogLevel": {"Default": "Information","Microsoft.AspNetCore": "Warning"}},"AppConfig": {"DirectoryPath": "项目本地日志存放路径"},"AllowedHosts": "*"
}

三.创建 Model 文件夹，创建AppConfig类和ErrorLog类

1.在AppConfig类中编写一个GetConfigInfo方法获取配置文件中的值

/// <summary>
/// 获取.NetCore配置文件信息
/// </summary>
public class AppConfig
{public static string GetConfigInfo(string Key){var builder = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json");IConfigurationRoot configuration = builder.Build();string configStr = configuration.GetSection($"{Key}").Value;if (!string.IsNullOrWhiteSpace(configStr)){return configStr;}return null;}}

2.在ErrorLog类中，实现往日志文件中书写接口日志的操作

public class ErrorLog
{//获取日志文件路径private static string DirectoryPath = AppConfig.GetConfigInfo("AppConfig:DirectoryPath");/// <summary>/// 写入操作日志到文件中/// </summary>/// <param name="moduleName">模块名字</param>/// <param name="message">错误文本信息</param>/// <param name="ex">异常</param>public static void Write(string message, Exception ex){string directoryPath = $@"{DirectoryPath}{DateTime.Now.ToString("yyyyMMdd")}"; // 目标目录路径if (!Directory.Exists(directoryPath)){// 如果目录不存在，则新建文件夹Directory.CreateDirectory(directoryPath);}string filePath = directoryPath + $@"\{DateTime.Now.ToString("yyyyMMddHH")}.log"; // 目标文件路径if (!File.Exists(filePath)){// 如果文件不存在，则创建文件using (File.Create(filePath)){//Console.WriteLine("文件已创建");}}LogToFile(filePath, message);}/// <summary>/// 写入操作日志到文件中/// </summary>/// <param name="moduleName">模块名字</param>/// <param name="ex">异常</param>public static void Write(string moduleName, Exception ex){Write(moduleName, moduleName, ex);}/// <summary>/// 写入过程数据或说明到文件中，以便跟踪/// </summary>/// <param name="moduleName">模块名字</param>/// <param name="ex">异常</param>public static void Write(string message){Write(String.Empty, message, null);}/// <summary>/// 文本写入/// </summary>/// <param name="logMessage"></param>private static void LogToFile(string logFilePath, string logMessage){using (StreamWriter sw = File.AppendText(logFilePath)){sw.WriteLine($"{logMessage}");}}
}

四.创建Filter文件夹，创建ActionFilter实现行动过滤器，实现记录接口日志

这里我们引入Newtonsoft.Json包

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Controllers;
using Microsoft.AspNetCore.Mvc.Filters;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.Json.Serialization;
using Newtonsoft.Json;
using System.Diagnostics;
using System.Text.Json;
using Microsoft.Extensions.Primitives;
using WebApiTest.Model;
using System.Net.Http.Json;namespace WebApiTest.Filter
{/// <summary>/// 方法过滤器/// </summary>public class ActionFilter : IActionFilter{/// <summary>/// 监控日志/// </summary>public static ILogger LoggerMonitor { get; set; }/// <summary>/// 错误日志/// </summary>public static ILogger LoggerError { get; set; }private Stopwatch _stopwatch;/// <summary>/// 创建请求日志文本/// </summary>/// <param name="method"></param>/// <param name="controllerName"></param>/// <param name="actionName"></param>/// <param name="actionArgs"></param>/// <returns></returns>private static string CreateRequestLogText(string method, string controllerName, string actionName, string requestHead, string requestBody){StringBuilder sb = new StringBuilder();sb.Append($"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss:fff")} 请求{method}/{controllerName}/{actionName}接口，请求Head：{requestHead}\n");sb.Append($"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss:fff")} 请求{method}/{controllerName}/{actionName}接口，请求Body：{requestBody}\n");return sb.ToString();}	/// <summary>/// 创建响应日志文本/// </summary>/// <param name="method"></param>/// <param name="controllerName"></param>/// <param name="actionName"></param>/// <param name="result"></param>/// <returns></returns>private static string CreateResponseLogText(string method, string controllerName, string actionName, object result){StringBuilder sb = new StringBuilder();sb.Append($"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss:fff")} 完成请求{method}/{controllerName}/{actionName}接口，返回结果：");if (result != null){sb.Append($"{JsonConvert.SerializeObject(result)}");}else{sb.Append($"无");}return sb.ToString();}/// <summary>/// 方法执行前，记录接口请求参数/// </summary>/// <param name="context"></param>/// <exception cref="NotImplementedException"></exception>public async void OnActionExecuting(ActionExecutingContext context){ErrorLog.Write("==================================================================================================================================");_stopwatch = new Stopwatch();_stopwatch.Start();//throw new NotImplementedException();if (LoggerMonitor != null){//记录请求参数日志ControllerActionDescriptor desc = context.ActionDescriptor as ControllerActionDescriptor;if (desc != null){Dictionary<string, object> headers = new Dictionary<string, object>();var requestHeaders = context.HttpContext.Request.Headers;// 访问请求中的 header 信息foreach (var header in requestHeaders){headers.Add(header.Key, header.Value);}var requestHead = JsonConvert.SerializeObject(headers);Dictionary<string, object> bodys = new Dictionary<string, object>();var actionArguments = context.ActionArguments;// 访问请求中的参数foreach (var argument in actionArguments){//dic.Add(argument.Key, argument.Value);var parameter = JsonConvert.DeserializeObject<Dictionary<string, object>>(argument.Value.ToString());foreach (var item in parameter){bodys.Add(item.Key, item.Value);}}var requestBody = JsonConvert.SerializeObject(bodys);var logText = CreateRequestLogText(context.HttpContext.Request.Method, desc.ControllerName, desc.ActionName, requestHead, requestBody);LoggerMonitor.LogDebug(logText);ErrorLog.Write(logText);}}}//方法执行后，记录接口请求结果public void OnActionExecuted(ActionExecutedContext context){//throw new NotImplementedException();_stopwatch.Stop();long elaspsedMillisedconds = _stopwatch.ElapsedMilliseconds;string msg = $"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss:fff")} 接口执行时间：{elaspsedMillisedconds}毫秒";//ErrorLog.Write(msg);if (context.Exception != null){// 记录异常日志if (LoggerError != null){LoggerError.LogError(context.Exception, context.Exception.Message);ErrorLog.Write($@"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss:fff")} 接口异常：{JsonConvert.SerializeObject(context.Exception)}");ErrorLog.Write($@"{DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss:fff")} 异常提示信息：{JsonConvert.SerializeObject(context.Exception.Message)}");}}if (LoggerMonitor != null){// 记录请求结果日志ControllerActionDescriptor desc = context.ActionDescriptor as ControllerActionDescriptor;if (desc != null){ObjectResult rst = context.Result as ObjectResult;object rstValue = rst != null ? rst.Value : null;var logText = CreateResponseLogText(context.HttpContext.Request.Method,desc.ControllerName,desc.ActionName,rstValue);LoggerMonitor.LogDebug(logText);ErrorLog.Write(logText);}}ErrorLog.Write(msg);ErrorLog.Write("==================================================================================================================================");}}
}

五.在 Program 中配置行动过滤器 ActionFilter

using Microsoft.AspNetCore.Mvc.Filters;
using WebApiTest.Filter;var builder = WebApplication.CreateBuilder(args);var configuration = builder.Configuration;
// Add services to the container.builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();#region 接口行动过滤器
// Add services to the container.
builder.Services.AddSingleton<IActionFilter>(new ActionFilter()); // 初始化 LoggerMonitor
builder.Services.AddSingleton<IActionFilter>(new ActionFilter()); // 初始化 LoggerError
builder.Services.AddScoped<ActionFilter>(); // 注册 ActionFilterbuilder.Services.AddControllers(options => {options.Filters.Add(new ActionFilter());
});var serviceProvider = builder.Services.BuildServiceProvider();
ActionFilter.LoggerError = serviceProvider.GetRequiredService<ILogger<ActionFilter>>();
ActionFilter.LoggerMonitor = serviceProvider.GetRequiredService<ILogger<ActionFilter>>();
#endregionvar app = builder.Build();// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{app.UseSwagger();app.UseSwaggerUI();
}app.UseAuthorization();app.MapControllers();app.Run();

六.创建一个接口，调试执行一下

using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;namespace WebApiTest.Controllers
{[ApiController][Route("Home")]public class HomeController : ControllerBase{[HttpGet][Route("Index")]public string Index(){return JsonConvert.SerializeObject(new { code = 0,data=true,msg="成功"});}}
}

接口请求成功，接着我们查看appsettings.json中配置的路径文件中，日志的记录情况

结果

.NetCore6.0项目，ActionFilter行动过滤器搭建成功，之后这个框架的接口请求就都会携带日志了
