Asp.net mvc MVC Authorize属性验证JSON值

我有以下代码，它可以在URL为/Projects/{userId}/{Id}的情况下正常工作

但是如果我用/Projects/和JSON值将值发布到页面上

{"userId":1234,"Id":145}

它不会拾取JSON值，UserId和Id都为null

代码如下

protected override bool AuthorizeCore(HttpContextBase httpContext)
{
    int documentIdfound, userIdFound;
    int? documentId = null;
    var documentIdRoute = httpContext.Request.RequestContext.RouteData.Values["Id"];

    if (int.TryParse((string)documentIdRoute, out documentIdfound))
        documentId = documentIdfound;

    //if we havent found the ProjectId in the RouteData check the querystring. Just in case
    if (documentId == null)
    {
        documentIdRoute = httpContext.Request.QueryString["Id"];
        if (int.TryParse((string)documentIdRoute, out documentIdfound))
            documentId = documentIdfound;
    }

    var userIdRoute = httpContext.Request.RequestContext.RouteData.Values["userId"];

    int.TryParse((string)userIdRoute, out userIdFound);

    var gi = GetCurrentUser();

    try
    {
        var userFound = gi.UserProfiles.Where(x => x.UserId == userIdFound).FirstOrDefault();
        if (userFound != null)
        {
            return gi.IsUserValid(userFound.UserId, documentId.Value);
        }
        else
            return false;
    }
    catch (Exception ex)
    {
        AddErrorToDB(ex);
        return false;
    }
}

尝试将参数值作为字符串发送：

{'userId'：'1234'，'Id'：'145'}

这将解决问题。

将json绑定到变量应该是一个模型绑定器问题。为此，您需要添加costum json模型绑定器
