ASP.NET 核心错误处理错误信息

Question

我开始着手 ASP.NET 核心错误处理，我注意到我收到格式错误

{
    "errors": {},
    "type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
    "title": "One or more validation errors occurred.",
    "status": 400,
    "traceId": "|caeb2316-47fb93bd8a17bc0a."
}

我正在尝试获取更详细的错误消息，但我无法摆脱此消息。

我只是按照 Handle errors in ASP.NET Core 上的说明操作，但错误总是存在。

如何摆脱这种格式的错误消息？

使用以下代码，您可以创建自定义错误响应或自定义问题详细信息：

services.AddControllers()
 .ConfigureApiBehaviorOptions(o =>
 {
     o.InvalidModelStateResponseFactory = context =>
     {
         var problemsDetailsFactory = context.HttpContext.RequestServices
             .GetRequiredService<ProblemDetailsFactory>();
         var problemDetails = problemsDetailsFactory.CreateValidationProblemDetails(
             context.HttpContext, 
             context.ModelState);
         problemDetails.Detail = "Custom Details";
         problemDetails.Instance = context.HttpContext.Request.Path;
         problemDetails.Type = "https://tools.etf............";
         //problemDetails.Status = StatusCodes.Status422UnprocessableEntity;
         problemDetails.Status = StatusCodes.Status400BadRequest;
         problemDetails.Title = "One or more errors on input occured";
         return new BadRequestObjectResult(problemDetails)
         {
             //ContentTypes= {"application/custom+json"}
         };
     };
 });
