如何在 Json 控制器操作中对用户进行身份验证？

我有一个 .NET MVC 控制器操作，它将 JsonResult 返回到 YUI AsyncRequest 回调。 AsyncRequest 调用一切正常，并且“内容”模型数据已成功更新。我现在如何确保用户在发出 AsyncRequest 之前已登录？

通常我会使用 [Authorize] 属性，它会向我的 YUI AsyncRequest 返回错误，因为它需要 Json 结果。

我也尝试过在操作中检查“User.Identity.IsAuthenticated”，但仍然没有爱。RedirectToRoute 似乎什么也没做。

我已经能够将 Json 结果发送回 JS，指示用户需要登录，但我宁愿让它将用户重定向到登录视图。

这是控制器操作：

[JsonFilter(Param="content"), JsonDataType=typeof(Content)]
public ActionResult SaveJson(Content content) 
{

    if (!User.Identity.IsAuthenticated)
        RedirectToRoute(new { Action="LogOn", Controller="Account"});


    contentRepository.Update(content);
    return Json(new {Result = "sucess"});

}

TIA！

I have a .NET MVC controller action that returns a JsonResult to a YUI AsyncRequest callback. All is working fine with the AsyncRequest call and the "Content" model data is successfully updated. How can I now assure that the user is logged before the AsyncRequest is made?

Normally I would use the [Authorize] attribute which returns an error back to my YUI AsyncRequest since it is expecting a Json result.

I've also tried checking "User.Identity.IsAuthenticated" wihtin the Action but still no love.. The RedirectToRoute seems to do nothing.

I have been able to send a Json result back to JS that indicated the user needs to login, but I'd rather have it redirect the user to the LogOn view.

Here is the Controller action:

[JsonFilter(Param="content"), JsonDataType=typeof(Content)]
public ActionResult SaveJson(Content content) 
{

    if (!User.Identity.IsAuthenticated)
        RedirectToRoute(new { Action="LogOn", Controller="Account"});


    contentRepository.Update(content);
    return Json(new {Result = "sucess"});

}

TIA!

您可以执行以下操作：

[JsonFilter(Param="content"), JsonDataType=typeof(Content)]
public ActionResult SaveJson(Content content) 
{

    if (!User.Identity.IsAuthenticated)
    {
        var urlHelper = new UrlHelper(ControllerContext.RequestContext);
        return Json(new {Result = "unauthenticated" , Url = urlHelper.Action("LogOn", "Account")});
    }

    contentRepository.Update(content);
    return Json(new {Result = "sucess"});
}

您将使用结果的 urlHelper.Action("LogOn", "Account") 部分将位置更改为登录页面 (window.location.href = ... ）。

附加说明：您可以将 urlHelper.Action("LogOn", "Account") 移动到您的视图，作为回调函数的一部分。

You can do something like:

[JsonFilter(Param="content"), JsonDataType=typeof(Content)]
public ActionResult SaveJson(Content content) 
{

    if (!User.Identity.IsAuthenticated)
    {
        var urlHelper = new UrlHelper(ControllerContext.RequestContext);
        return Json(new {Result = "unauthenticated" , Url = urlHelper.Action("LogOn", "Account")});
    }

    contentRepository.Update(content);
    return Json(new {Result = "sucess"});
}

You will use urlHelper.Action("LogOn", "Account") part of result to change location to login page (window.location.href = ...).

Additional note: You can move urlHelper.Action("LogOn", "Account") to your view, as a part of your callback function.

我认为语义上正确的做法是返回带有 401（未经授权）状态代码的 HTTP 响应，并让 js 决定如何响应。我不熟悉 YUI，但在 jQuery 中你可以像这样设置错误回调函数......

function BasicJSONPost(urlToPost, dataToSend, onSuccess) {
$.ajax({
    url: urlToPost,
    data: dataToSend,
    dataType: "json",
    type: "POST",
    success: onSuccess,
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        HandleAjaxError(XMLHttpRequest, textStatus, errorThrown);
    }
});
}

function HandleAjaxError(XMLHttpRequest, textStatus, errorThrown) {
    if (XMLHttpRequest.status == 401) {
        window.location.href = '/account/login';
    }
}

I think the semantically correct thing to do is return an HTTP response with a 401 (Unauthorized) status code and let the js decide how to respond. I'm not familiar with YUI, but in jQuery you can setup an error callback function like so...

function BasicJSONPost(urlToPost, dataToSend, onSuccess) {
$.ajax({
    url: urlToPost,
    data: dataToSend,
    dataType: "json",
    type: "POST",
    success: onSuccess,
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        HandleAjaxError(XMLHttpRequest, textStatus, errorThrown);
    }
});
}

function HandleAjaxError(XMLHttpRequest, textStatus, errorThrown) {
    if (XMLHttpRequest.status == 401) {
        window.location.href = '/account/login';
    }
}
