您可以使用异常过滤器来处理异常并轻松操纵响应.

You can use exception filter to handle exceptions and easily manipulate response.

public class ExceptionFilter : IExceptionFilter
{


    public ExceptionFilter(IHostingEnvironment env, ILogger<JsonExceptionFilter> logger)
    {
        _env = env;
        _logger = logger;
    }

    public void OnException(ExceptionContext context)
    {
        var error = new ApiResponse();
        var exceptionName = context.Exception.GetType().Name;
        var message = context.Exception.Message;

        if (_env.IsDevelopment())
        {
            error.Message = context.Exception.Message;
            error.Detail = context.Exception.StackTrace;  
        }
        else
        {
           //Prevent To Show Exception Messages On Production
            error.Message = "Server Error Occured";
            error.Detail = "Something wrong happened";  
        }

        context.Result = new ObjectResult(error)
        {
            //Manipulate Status Code
            StatusCode = 500
        };
    }

}

并注册到Startup.cs

And register to Startup.cs

public void ConfigureServices(IServiceCollection services){

        services.AddMvc(options =>
        {
            //Catch the exceptions
            options.Filters.Add<ExceptionFilter>();
        }).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

 }
