问题描述
我有这样的jQuery的电话后这在某种程度上被调用的误差函数，即使它把数据输入数据库完美的罚款。
＆LT;脚本类型=文/ JavaScript的＆GT;
$（文件）。就绪（函数（）{
$（＃ExtMailCreate）。点击（函数（）{
VAR URL ='@ Url.Action（创建）;
VAR数据= JSON.stringify（SaveExternalMail（））;
$阿贾克斯（{
键入：POST，
网址：网址，
数据：数据，
数据类型：JSON
的contentType：应用/ JSON的;字符集= UTF-8，
成功：功能（数据）{
$（＃结果）追加（通行证）;
}，
错误：功能（数据）{
$（＃结果）追加（错误）。
}
}）;
}）;
}）; 功能SaveExternalMail（）{
。VAR costcentre code = $（＃CostCentre code）VAL（）;
。VAR天= $（＃ExtMailDatePicker）VAL（）;
变种externalMailItemID = $（＃ExternalMailItemID）VAL（）;
变种externalMailLocationID = $（＃ExternalMailLocationID）VAL（）;
变种数量= $（＃数量）VAL（）。
返回{
CostCentre code：costcentre code，
日：当天，
ExternalMailItemID：externalMailItemID，
ExternalMailLocationID：externalMailLocationID，
数量：数量
};
}
＆LT; / SCRIPT＆GT;
- 控制器
＆LT; HttpPost（）＆GT; _
功能创建（BYVAL收集作为ExternalMail）由于JsonResult
尝试
如果ModelState.IsValid然后
_repositoryForExternalMail.Save（收集，）
万一 返回JSON（新ExternalMail随着{.CostCentre code = collection.CostCentre code，.DAY = collection.Day，.Quantity = collection.Quantity}，JsonRequestBehavior.AllowGet） 抓住EX为例外
返回JSON（一个错误发生）
结束Try
结束功能

解决方案
I think the problem is specifying JsonRequestBehavior.AllowGet
and then posting to the method:
$.ajax({
type: "POST",
url: url,
If the database is getting populated, we know the repository code is firing. The browser is reporting an HTTP403 which smells like the framework is throwing a security exception, which it may do if it's expecting to respond to GET and receives a POST.
