MVC Http PUT不起作用

Question

when using HTTP post to update my times record for example it works, but when i use put it doesn't. I have read some articles about CRUD and HTTP methods, and as known HTTP PUT is for the update part, is it only for WEB API or can i use it in my .net mvc project and im doing something wrong? Here's my code

var times = GetTimes(); // times array object

var enrollmentId = $('#EnrolledSubject').data('id');

$.ajax({
    contentType: 'application/json; charset=utf-8',
    url: "/Subjects/UpdateTimes?enrollmentId="+enrollmentId,
    type: "PUT",
    dataType: "json",
    data: JSON.stringify({ 'times': times}),
    success: function (data) {
        console.log(data);
    },
    error: function (x, y, z) {
        console.log('error ' + y);

        OnAJAXError(x, y, z);
    }
});

and MVC controller Subjects

[Route("UpdateTimes")]
[HttpPut]
public bool UpdateTimes(List<Time> times)
{
     return true;
}

The issue might be coming from your iis configuration. You could try adding this in your web.config :

<system.webServer>
    <handlers>
        <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
        <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
</system.webServer>
