问题描述
在最新的.NET Core 2.1中，引入了用于模型状态验证的自动验证（）。
In the latest .NET Core 2.1, an automatic validation for the model state validation is introduced (https://blogs.msdn.microsoft.com/webdev/2018/02/02/asp-net-core-2-1-roadmap/#mvc).
以前，我可以通过以下代码覆盖验证错误响应：
Previously I could override the validation error response by the following code below:
public class ApiValidateModelAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext context)
{
if (!context.ModelState.IsValid)
{
context.Result = new BadRequestObjectResult(new context.ModelState);
}
base.OnActionExecuting(context);
}
但是现在它不再起作用了。无需输入重写方法即可响应验证错误。
But now it no longer works. The validation errors is responded without entering the override method.
任何人都有线索吗？
谢谢。
Anyone has any clue?Thanks.
推荐答案
如果您想继续使用 ApiController 属性（它具有其他功能，例如禁用常规路由并允许模型绑定而无需添加 [FromBody] 参数属性），您可以通过您的 Startup.cs 文件：
If you'd like to keep using the ApiController attribute (which has other functions like disabling conventional routing and allowing model binding without adding [FromBody] parameter attributes), you might be able to do it via this in your Startup.cs file:
services.Configure<ApiBehaviorOptions>(opt =>
{
opt.SuppressModelStateInvalidFilter = true;
});
这样可以使ModelState无效时，不会自动返回400错误。
That will make it so that if the ModelState is invalid it won't automatically return a 400 error.
