Jquery 使用Ajax和MVC保存数据

我通过MVC使用jQueryAjax将数据保存到SQLServer中，并传递json数据。当我的数据很小时，它工作正常，但当我的json包含大数据时，它在命中$.ajax时表示内部服务器错误

这是我的代码，dr是另一个类的对象，它通过EF将数据保存到数据库中

var dto = {
    'ob': ob
};
$.ajax({
    url: "/Recieve/Create",
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    type: "POST",
    beforeSend: function () {
        link.addClass('loading');
    },
    data: JSON.stringify(dto),
    success: function (msg) {
        link.removeClass('loading');
        if (msg != null) {
            if (msg.URL == "/Error") {
                if (msg.dublist != "") {
                    noty({
                        text: "Item SrNo" + msg.dublist + " with same vendor already exist/Please Check Values...",
                        type: "error"
                    });


                    var data = msg.dublist.split(',');
                    for (var k = 0; k < data.length; k++) {

                        for (var xy = 0; xy < $("#Details tbody tr").length; xy++) {
                            var y = $("#iFromNo", xy).val();
                            if (y == data[k]) {
                                $("#Details tbody tr," + xy + " ").css("background-color", "red");
                                //$('tr:nth-child(odd)').addClass('odd');
                            } else {
                                $("#Details tbody tr," + xy + " ").css("background-color", "yellow");
                            }
                        }
                    }

                } else {
                    noty({
                        text: "Error Occured..",
                        type: "error"
                    });
                }
            } else {
                window.location = msg.URL;
            }
        }
    }
});


public JsonResult Create(RecieveViewModel ob) {
    string path = "/Error";
    string duplicateItems = "";
    int finalRecId = 0;
    try {
        var centerId = SessionWrapper.Account == null ? "" : SessionWrapper.Account.DefaultCenterId == null ? "" : SessionWrapper.Account.DefaultCenterId;
        var createdby = SessionWrapper.Account == null ? "" : SessionWrapper.Account.UserName == null ? "" : SessionWrapper.Account.UserName;
        if (ob.Details.Count() > 0 && centerId.Length > 0) {
            //updated on 26th dec 2012
            finalRecId = _dr.SaveReceiveMasterAndDetails(ob, out duplicateItems);
            if (finalRecId > 0) {
                var sessionid = string.Empty;
                if (HttpContext.Session != null) sessionid = HttpContext.Session.SessionID;

                _dr.DeleteTempBySession(sessionid);

                path = Url.Action("Index");
            }
        } else {
            path = "/Error";
        }
    } catch (Exception ex) {
        path = "/Error" + ex.Message;
    }
    return Json(new {
        URL = path,
        dublist = duplicateItems
    }, JsonRequestBehavior.AllowGet);
}

内容长度存在问题。检查这个答案，并在您的位置相应地配置您的web配置。我将使用Fiddler来确定MVC抛出的底层错误。如果查看返回的响应，通常会发现一条相当清晰的错误消息。如果在我的计算机上调试相同的消息，则不会发生错误。只有当我上传我的dll时，它才会出现
