配置.net核心日志记录以记录请求和响应-Java 学习之路

我正在开发asp .net core 2.1 WEB-API应用程序 .

我使用ILogger配置：

"Logging": {
"LogLevel": {
  "Default": "Debug",
  "System": "Information",
  "Microsoft": "Information"
}

并根据要求我看到日志：

info：Microsoft.AspNetCore.Mvc.Internal.ControllerActionInvoker [1]使用参数执行操作方法ActivationService.Controllers.ActivationController.Post（ActivationService）（ActivationService.Contracts.ActivationRequest） - 验证状态：有效

和

执行的操作方法ActivationService.Controllers.ActivationController.Post（ActivationService），返回结果Microsoft.AspNetCore.Mvc.ObjectResult in 174605.9201ms .

是否有办法使用跟踪 body 的响应和请求来使用asp.net进行日志记录？

是的，您可以实现日志记录中间件：

public class RequestResponseLoggingMiddleware
    {
        private readonly RequestDelegate next;
        private readonly ILogger logger;

        public RequestResponseLoggingMiddleware(RequestDelegate next, ILoggerFactory loggerFactory)
        {
            this.next = next;
            logger = loggerFactory.CreateLogger<RequestResponseLoggingMiddleware>();
        }

        public async Task Invoke(HttpContext context)
        {
            context.Request.EnableRewind();

            var buffer = new byte[Convert.ToInt32(context.Request.ContentLength)];
            await context.Request.Body.ReadAsync(buffer, 0, buffer.Length);
            var requestBody = Encoding.UTF8.GetString(buffer);
            context.Request.Body.Seek(0, SeekOrigin.Begin);

            logger.LogInformation(requestBody);

            var originalBodyStream = context.Response.Body;

            using (var responseBody = new MemoryStream())
            {
                context.Response.Body = responseBody;

                await next(context);

                context.Response.Body.Seek(0, SeekOrigin.Begin);
                var response = await new StreamReader(context.Response.Body).ReadToEndAsync();
                context.Response.Body.Seek(0, SeekOrigin.Begin);

                logger.LogInformation(response);
                await responseBody.CopyToAsync(originalBodyStream);
            }
        }
    }

然后在Configure方法中将其添加到application Builder：

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    ....
    app.UseMiddleware<RequestResponseLoggingMiddleware>();
}
