使用jquery传递复杂Json数据——[ModelBinder(typeof(JsonBinder<复杂实体类>))]

调用jQuery的ajax方法时,jQuery会根据post或者get协议对参数data进行序列化;

如果提交的数据使用复杂的json数据,例如:

{userId:32323,userName:{firstName:"李",lastName:"李大嘴"}}

那么服务器是无法正常接收到完整的参数,因为jQuery对data的序列化,是使用了键值对拼装的方式;

参数拼装成 userId=32323&userName=object ; userName所指向的对象被序列化成字符串"object"

        public ActionResult Add([ModelBinder(typeof(JsonBinder<CostItem>))]CostItem costItem)

$(function() {
/*按钮点击事件*/
$("#btn_post_test").click(function() {
var data = [
{ UserId: "11", UserName: { FirstName: "323", LastName: "2323" }, Keys: ["xiaoming", "xiaohong"] },
{ UserId: "22", UserName: { FirstName: "323", LastName: "2323" }, Keys: ["xiaoming", "xiaohong"] },
{ UserId: "33", UserName: { FirstName: "323", LastName: "2323" }, Keys: ["xiaoming", "xiaohong"] }
];
$.post("Home/Test", { users: String.toSerialize(data) }, function(text) {
alert(String.toSerialize(text));
}, "json");
});
});

public ActionResult Test([ModelBinder(typeof(JsonBinder<User>))]List<User> users)
{
return Json(users, JsonRequestBehavior.AllowGet);
}
}
