I'm still learning web API, so pardon me if my question sounds stupid.
I have this in my StudentController
:
public HttpResponseMessage PostStudent([FromBody]Models.Student student) { if (DBManager.createStudent(student) != null) return Request.CreateResponse(HttpStatusCode.Created, student); else return Request.CreateResponse(HttpStatusCode.BadRequest, student); }
In order to test if this is working, I'm using Google Chrome's extension "Postman" to construct the HTTP POST request to test it out.
This is my raw POST request:
POST /api/Student HTTP/1.1 Host: localhost:1118 Content-Type: application/json Cache-Control: no-cache {"student": [{"name":"John Doe", "age":18, "country":"United States of America"}]}
student
is supposed to be an object, but when I debug the application, the API receives the student
object but the content is always null
.
FromBody is a strange attribute in that the input POST values need to be in a specific format for the parameter to be non-null, when it is not a primitive type. (student here)
{"name":"John Doe", "age":18, "country":"United States of America"}
as the json. [FromBody]
attribute and try the solution. It should work for non-primitive types. (student)[FromBody]
attribute, the other option is to send the values in =Value
format, rather than key=value
format. This would mean your key value of student
should be an empty string... There are also other options to write a custom model binder for the student class and attribute the parameter with your custom binder.
