最初にコードを持ってきます。

コントローラ：

    public ActionResult VideoList(int page)
    {
    }
    [HttpPost]
    public ActionResult SaveWindowWidth(string width)
    {
        return Json(new { success = true });
    }

JS:

$(document).ready(function ()
{
var width = $("#Window").width();

$.ajax(
    {
        type: "POST",
        url: '/Video/SaveWindowWidth',
        async: "true",
        data: { "width": width },
        dataType: 'text json',
        contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
        success: function (data, status)
        {
            if (data)
            {
                alert(data.status);
            }
        },
        error: function (data, status)
        {
            if (data)
            {
                alert(data.status);
            }
        }
    })
})

ajax が VideoList メソッドを呼び出そうとする問題。応答を読むと表示されます：

パラメーター ディクショナリに、メソッド 'System.Web.Mvc.ActionResult VideoList(Int32)' の null 非許容型 'System.Int32' のパラメーター 'page' の null エントリが含まれています。

ルートに問題があるのではないかとどこかで聞いたので、こちらにも載せておきます。助けていただければ幸いです

ビデオ ルートが適切に構成されていません。MVC は、各 URL からコントローラーとアクションを取得して、適切なコントローラーから必要なメソッドを見つけようとします。そしてあなたの場合、常に同じ値を取得します VideoController.VideoList():

routes.MapRoute(
            "Video", // Route name
            "Video/{page}", // URL with parameters
            new { controller = "Video", action = "VideoList" }
        );

ルートをこれに変更すると、すべて問題ありません。

routes.MapRoute(
            "Video", // Route name
            "Video/{action}", // URL with parameters
            new { controller = "Video", action = "VideoList" }
        );

Dima がこの問題を特定しましたが、彼の解決策はあなたにはうまくいきません。url をリクエストするときに、パラメーターを に設定してコントローラーでVideo/SaveWindowWidthアクションを呼び出すように、ルートが構成されています。明らかに、それはあなたが望んでいたものではありません。VideoListVideopageSaveWindowWidth

ASP.Net MVC は、一致する最初のルートを実行します。そのため、最初にすべての特定のルートを含めることが重要です。

これを修正する方法の 1 つは、特定の API ルートが一般的なプリティ ルートの上に設定されるようにルートを書き直すことです。そのためには、きれいな URL の前にすべての組み合わせを指定する必要があります。

例えば、

routes.MapRoute(
        "SaveWindowWidthForVideo", // Route name
        "Video/SaveWindowWidth",
        new { controller = "Video", action = "SaveWindowWidth" }
    );

routes.MapRoute(
        "SaveWindowHeightForVideo", // Route name
        "Video/SaveWindowHeight",
        new { controller = "Video", action = "SaveWindowHeight" }
    );

routes.MapRoute(
        "SaveWindowSomethingElseForVideo", // Route name
        "Video/SaveWindowHeight",
        new { controller = "Video", action = "SaveWindowSomethingElseForVideo" }
    );

// etc etc      

// your remaining pretty urls
routes.MapRoute(
        "Video", // Route name
        "Video/{page}", // URL with parameters
        new { controller = "Video", action = "VideoList" }
    );

それは非常に簡単に面倒になるので、私はそれを好まない。

私が好む解決策は、URL に単語を追加して、プリティ url ルートと ajax API ルートを区別することapiです。

routes.MapRoute(
        "ApiCallsForVideo", // Route name
        "api/video/{action}",
        new { controller = "Video" }
    );

// or

routes.MapRoute(
        "ApiCalls", // Route name
        "api/{controller}/{action}"
    );



// etc etc      

routes.MapRoute(
        "Video", // Route name
        "Video/{page}", // URL with parameters
        new { controller = "Video", action = "VideoList" }
    );

これには明らかに、 ajax 呼び出しを変更して単語を含める必要がありますapi。

URL はベスト プラクティスではないため、文字列を使用して値を格納します。

私はこのようなことをします。

意見

@Html.Hidden("getVideoUrl", Url.Action("SaveWindowWidth", "Video"))

JS

   var url = $("#getVideoUrl").val();
    $.post(url, data: { "width": width },      
        success: function (data, status)
        {
            if (data)
            {
                alert(data.status);
            }
        },
        error: function (data, status)
        {
            if (data)
            {
                alert(data.status);
            }
        });

こんにちは、ルートにパラメーターを追加する必要があると思います。その後、ajax のみがパラメーターを使用してそのメソッドを呼び出します。今起こっていることは、あなたの ajax がその特定のメソットを呼び出しているということですが、パラメータを許可するためにルートで言及していません

routes.MapRoute(
            "Video", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            new { controller = "Video", action = "VideoList", width= UrlParameter.Optional } // Parameter defaults
        );

その場合、ur パラメーターのみを ur コントローラーに渡すことができます。呼び出し元の URL は次のようになります

 url: '/Video/SaveWindowWidth'+width,

また

url: '/Video/SaveWindowWidth?width=' + width,

私にとってはうまくいきます！

それが役に立てば幸い
