how to validate model in asp.net core 3.1 web api post method?

Question

Hi

 

I have an api post method. I don't have any UI to use that api so i need to show my error message in postman. If I miss one property the missing property error message should be displayed in postman.i confused with many post in internet.

 

my post method

[HttpPost("api/Student/Check")]
public async Task Check([FromBody] students input)
{
var result = await _students.studentAsync(input);
return Ok(result);
}
my model
public class students
{
[JsonProperty("studentid")]
public int studentid{ get; set; }
[JsonProperty("studentname")]
public int studentname{ get; set; }
[JsonProperty("studentage")]
public int studentage{ get; set; }
}
}

I should get like:

 

Expected Result: Status code is 400 bad request and response should be as below:

 

student id is required.This cannot be null or blank.

student name is required.This cannot be null or blank

student age field is required.This cannot be null or blank.
