jquery - 无效的 JSON 类型 MVC 3

Question

我在整个网络上进行了搜索，我认为我正确使用了 JSON，但我只是找不到它的问题所在。我需要将此 json 对象作为 MVC Controller 操作的参数传递:

JSON:

{ 
"ContactId": "0",
"Fax2": "dsad",
"Phone2": "dsad",
"Tittle": "asdsa",
"Cellphone": "dsadsd", 
"Address": { "City": "kjshksdfks",
             "Country": "undefined",
             "Id": "0",
             "State": "dsadsa"}
}

.NET 对象如下:

public class Contact
{
    public string ContactId {get; set;}
    public string Fax2 {get; set;}
    public string Phone2 {get; set;}
    public string Tittle {get; set;}
    public string Cellphone {get; set;}
    public Address ContactAddress {get; set;}
}

嵌套地址类型如下:

public class Address
{
    public string City {get; set;}
    public string Country {get; set;}
    public int Id {get; set;}
    public string State {get; set;}
}

我的 JSON 有什么问题吗？为了将 clean 传递给 Controller ​​操作，我缺少什么

确切的错误是:无效的 JSON 原语:联系方式

注意:我尝试使用 javascript 对象、JSON.stringify 和 toJSON()

提前致谢!

我怀疑您缺少 ajax 调用的内容类型。另请参阅:http://forums.asp.net/t/1665485.aspx/1?asp+net+mvc+3+json+values+not+recieving+at+controller .

我更改了一些内容 1) 标题 -> 标题和地址 -> 联系地址；这应该有效:

JSON:

{
  "ContactId": "a",
  "Fax2": "b",
  "Phone2": "c",
  "Title": "d",
  "Cellphone": "e",
  "ContactAddress": {
      "Id": 22,
      "City": "a",
      "State": "b",
      "Country": "c"
    }
}

调用:

<script>
    var contact = { "ContactId": "a", "Fax2": "b", "Phone2": "c", "Title": "d", "Cellphone": "e", "ContactAddress": { "Id": 22, "City": "a", "State": "b", "Country": "c"} };

    $.ajax({
        type: 'POST',
        url: '[YOUR-URL]',
        data: JSON.stringify(contact),
        success: function (result) {
            alert('success');
        },
        dataType: "json",
        contentType: "application/json; charset=utf-8"
    });
</script>
