MVC3 RC2 JSON Post 绑定无法正常工作

我看过有关此主题的其他帖子，并尝试过各种变体，但仍然无法使 JSON 模型绑定正常工作。

我的 global.asax.cs Application_Start 方法中有以下内容：

ValueProviderFactories.Factories.Add(new JsonValueProviderFactory());

回发数据如下所示：

{"UserName":"Mike","Password":"password","Persist":true}

我的 PoCo：

public class UserLoginViewModel {
    public string UserName { get; set; }
    public string Password { get; set; }
    public bool Persist { get; set; }
}

控制器方法正常触发，但具有默认的 UserLoginViewModel 对象，其中 UserName = null、Password = null 和 Persist = false；签名看起来像这样：

[HttpPost]
public ActionResult Logon(UserLoginViewModel model) {
    if (ModelState.IsValid) { 
    ...

I've seen other posts on this subject and have fiddled with variations but still cannot not get the JSON model binding to work correctly.

I have the following in my global.asax.cs Application_Start method:

ValueProviderFactories.Factories.Add(new JsonValueProviderFactory());

The post back data looks like this:

{"UserName":"Mike","Password":"password","Persist":true}

My PoCo:

public class UserLoginViewModel {
    public string UserName { get; set; }
    public string Password { get; set; }
    public bool Persist { get; set; }
}

The controller method fires properly but has default UserLoginViewModel object with UserName = null, Password = null, and Persist = false; the signature looks like this:

[HttpPost]
public ActionResult Logon(UserLoginViewModel model) {
    if (ModelState.IsValid) { 
    ...

问题出在客户端！我没有设置 contentType。

$.ajax({
    url: location.href, 
    type: "POST",
    data: ko.toJSON(this),
    datatype: "json",
    **contentType: "application/json charset=utf-8",**
    success: function (data) { alert("success"); }, 
    error: function (data) { alert("error"); }
});

The problem is on the client side! I didn't have the contentType set.

$.ajax({
    url: location.href, 
    type: "POST",
    data: ko.toJSON(this),
    datatype: "json",
    **contentType: "application/json charset=utf-8",**
    success: function (data) { alert("success"); }, 
    error: function (data) { alert("error"); }
});
