NetCore 全局异常过滤器

第一步：创建过滤器

/// <summary>
/// 全局异常过滤器
/// 调用示例：throw new NotImplementedException();
/// </summary>
public class GlobalExceptionFilter : IExceptionFilter
{
    readonly IWebHostEnvironment hostEnvironment;
    public GlobalExceptionFilter(IWebHostEnvironment _hostEnvironment)
    {
        this.hostEnvironment = _hostEnvironment;
    }
    public void OnException(ExceptionContext context)
    {
        if (!context.ExceptionHandled)//如果异常没有处理
        {
            var result = ResponseMessage.Error("服务器发生未处理的异常");
            if (hostEnvironment.IsDevelopment())
            {
                result.Message += "," + context.Exception.Message;
                result.Data = context.Exception.StackTrace;
            }

            context.Result = new JsonResult(result);
            context.ExceptionHandled = true;//异常已处理
        }
    }
}

第二步：配置过滤器

builder.Services.AddControllers(option =>
{
    option.Filters.Add<GlobalExceptionFilter>();
}
);

 第四步：异常示例

[HttpGet("{id}")]
public ActionResult Get(int id)
{
    throw new NotImplementedException();
}
