jQuery Ajax发布参数在控制器中为null

问题描述

我有一个ajax POST请求:

I have an ajax POST request:

$.ajax({
    url: "/api/EmmaWeb/SaveFavourite", //window.location.pathname + "?handler=favourite", //"/it/Umbria/vocabolo-menicaglie-6?handler=favourite",
    type: "POST",
    headers: { "RequestVerificationToken": $('input[name="__RequestVerificationToken"]', $form).val() },
    //contentType: "application/jsonrequest; charset=utf-8",
    //contentType: 'application/json',
    //dataType: "json",
    data: JSON.stringify({ isFavourite: $inputIsFavourite.val().toLowerCase(), propertyUnitSlug: $PropertyUnitSlug.val() }),
    cache: false
}).done(function (resp) {
    console.log("done", resp);
});

我的控制器:

[ApiController]
[Route("/api/[controller]")]
public class EmmaWebController : Controller
{
    [HttpPost]
    [Route("[action]")]
    public async Task<IActionResult> SaveFavouriteAsync(bool isFavourite, string propertyUnitSlug)
    {
        // DO Something

        return new JsonResult(new
        {
            // Something
        });
    }
}

我在控制器中执行操作，但是参数始终为null.我尝试添加[FromBody]，但出现415错误

I reach my action in controller, but the parameters are always null. I tried adding [FromBody] but i get 415 error

推荐答案

我解决了从Controller中删除[ApiController]属性的问题，这就是ajax:

I Solved removing [ApiController] attribute from the Controller, and this is the ajax:

$.ajax({
    url: "/api/EmmaWeb/SaveFavourite", //window.location.pathname + "?handler=favourite", //"/it/Umbria/vocabolo-menicaglie-6?handler=favourite",
    type: "POST",
    headers: { "RequestVerificationToken": $('input[name="__RequestVerificationToken"]', $form).val() },
    //contentType: "application/jsonrequest; charset=utf-8",
    //dataType: "json",
    //contentType: 'application/json',
    //dataType: "json",
    data: { "isFavourite": $inputIsFavourite.val(), "propertyUnitSlug": $PropertyUnitSlug.val() },
    cache: false
})
