2.使用中间件，Configure中加入如下代码
1 app.UseCalculateExecutionTime();//Api计时
.Net 常用ORM框架对比：EF Core、FreeSql、SqlSuger (上篇) mybatis和dapper
1 public class CalculateExecutionTime 2 { 3 private readonly RequestDelegate _next;//下一个中间件 4 private readonly ILogger _logger; 5 Stopwatch stopwatch; 6 public CalculateExecutionTime(RequestDelegate next, ILoggerFactory loggerFactory) 7 { 8 if (loggerFactory == null) 9 {10 throw new ArgumentNullException(nameof(loggerFactory));11 }12 this._next = next ?? throw new ArgumentNullException(nameof(next));13 _logger = loggerFactory.CreateLogger();14 }15 16 public async Task Invoke(HttpContext context)17 {18 stopwatch = new Stopwatch();19 _logger.LogInformation($@"====接口{context.Request.Path}开始计时====");20 stopwatch.Start();//启动计时器21 await _next.Invoke(context);22 stopwatch.Stop();//停止秒表。23 _logger.LogInformation($@"====接口{context.Request.Path}耗时:{stopwatch.ElapsedMilliseconds}ms====");24 }25 }26 27 public static IApplicationBuilder UseCalculateExecutionTime(this IApplicationBuilder app)28 {29 if (app == null)30 {31 throw new ArgumentNullException(nameof(app));32 }33 return app.UseMiddleware();34 }
