如何使用状态码返回响应JSON数据？

Question

When I used MVC controllers I used "return OK(object);" or "return BadRequest(ErrorMessage)" and such.

How can I achieve this is Razor Pages?

I tried return new JsonResult(object); which works when the status code can be 200. But what if I want to return status code 400 with a JSON error message.

You can return a JsonResult from a Razor Page handler method, and set the HTTP status code for the response:

public IActionResult OnGet()
{
    Response.StatusCode = 400;
    return new JsonResult(new { message = "Error" } );
}
