如何处理razor.cs文件中的异常并在控制台中全局显示它们?BlazorWebAssembly

使用program.cs并在asp.net管道上添加中间件。

这是一个AdvanceExceptionHandler示例:

namespace AryaVtd.Orca.Server.Infrastructure.Middlewares.Logging
{
    public class AdvancedExceptionHandler
    {
        private readonly RequestDelegate _next;
        private readonly ILogger _logger;
        private readonly IWebHostEnvironment _env;

        public AdvancedExceptionHandler(RequestDelegate next, ILoggerFactory logger, IWebHostEnvironment env)
        {
            _next = next;
            _logger = logger.CreateLogger(typeof(AdvancedExceptionHandler).Name);
            _env = env;
        }

        public async Task Invoke(HttpContext context)
        {
            string message = null;
            HttpStatusCode httpStatusCode = HttpStatusCode.InternalServerError;

            try
            {
                await _next(context);
            }
            catch (Exception ex)
            {
                _logger.LogError($"AryaVtd.Orca.Server.Infrastructure.Middlewares.Logging:\r\nSource: {ex.Source} \r\nMessage: {ex.GetMessages()}");

                if (_env.IsDevelopment())
                {
                    var dic = new Dictionary<string, string>
                    {
                        ["StackTrace"] = ex.StackTrace,
                        ["Exception"] = ex.Message
                    };
                    message = JsonConvert.SerializeObject(dic);
                }
                else
                {
                    message = "AdvancedExceptionHandler: unfortunately an error has occurred on server!";
                }

                await WriteToReponseAsync();
            }

            async Task WriteToReponseAsync()
            {
                var exceptionResult = new ExceptionResult(message, (int)httpStatusCode);
                var result = JsonConvert.SerializeObject(exceptionResult);
                context.Response.StatusCode = (int)httpStatusCode;
                context.Response.ContentType = "application/json";

                await context.Response.WriteAsync(result);
            }
        }
    }

    public static class ExceptionHandlerMiddlewareExtension
    {
        public static void UseAdvancedExceptionHandler(this IApplicationBuilder app)
        {
            app.UseMiddleware<AdvancedExceptionHandler>();
        }
    }
}

呼叫应用程序。在program.cs的早期使用AdvancedExceptionHandler()。

app.UseAdvancedExceptionHandler();
