我试图创建一个JSON对象，它可以作为C#对象读取，当我试图通过AJAX发送它时，我不断收到400个错误的请求

我的JavaScript如下所示：

$.ajax({
type: "POST",
url: "LeagueService.svc/Fixtures",
    data: JSON.stringify(fixture),
    dataType: "json",
    contentType: "application/json",
    success: function (json, status, req) {
        $successMessage = '<div class="hero-unit"><h2>Success</h2><p>The fixture has been added to the database.</p></div>';

        $('#dialog').html($successMessage).fadeOut(500, function (e) {
            $(this).dialog("close");
        });

     },
     error: function (req, status, error) {
       alert('Error: ' + req.responseText);
     }
});

{ "fixture": {
    "ID":0,
    "HomeTeam":{
        "ID":1,
        "Name":"Rhondda St FC",
        "Wins":21,
        "Losses":2,
        "Draws":4,
        "GoalsConceded":20,
        "GoalsScored":36,
        "Manager": {
            "ID":1,
            "Name":"Ron Burgundy"
        }
    },
    "AwayTeam": {
        "ID":2,
        "Name":"Mt Pleasant United FC",
        "Wins":18,
        "Losses":5,
        "Draws":3,
        "GoalsConceded":22,
        "GoalsScored":28,
        "Manager": { 
            "ID":2,
            "Name":"Brian Fantana"
        }
    },
    "Date":"02/19/2013 12:00pm"
}}

这种方法在我编写的其他函数中工作得非常好，所以我不确定现在出了什么问题

我的C#方法和接口：接口：

[OperationContract]
[WebInvoke(Method = "POST",
    BodyStyle = WebMessageBodyStyle.Wrapped,
    RequestFormat = WebMessageFormat.Json,
    ResponseFormat = WebMessageFormat.Json,
    UriTemplate = "/Fixtures")]
void AddFixture(Fixture fixture);

方法是：

public void AddFixture(Fixture fixture)
{
    using (SqlConnection conn = new SqlConnection(Properties.Settings.Default.DBConnect))
    {
        try
        {
            conn.Open();
            string query = "INSERT INTO tbFixtures (HomeTeam, AwayTeam, Date) VALUES(@HT, @AT, @Date);";
            using (SqlCommand cmd = new SqlCommand(query, conn))
            {
                cmd.Parameters.AddWithValue("@HT", fixture.HomeTeam.ID);
                cmd.Parameters.AddWithValue("@AT", fixture.AwayTeam.ID);
                cmd.Parameters.AddWithValue("@Date", fixture.Date);

                cmd.ExecuteNonQuery();
            }
        }
        catch (Exception) { }
        finally
        {
            conn.Close();
        }
    }
}

以及C#类：

Manager和Team类的编写方式与JavaScript中Fixture类的编写方式完全相同

该对象序列化为我认为正确的JSON，但如果我遇到这些错误，显然不会。生成的JSON如下所示：

$.ajax({
type: "POST",
url: "LeagueService.svc/Fixtures",
    data: JSON.stringify(fixture),
    dataType: "json",
    contentType: "application/json",
    success: function (json, status, req) {
        $successMessage = '<div class="hero-unit"><h2>Success</h2><p>The fixture has been added to the database.</p></div>';

        $('#dialog').html($successMessage).fadeOut(500, function (e) {
            $(this).dialog("close");
        });

     },
     error: function (req, status, error) {
       alert('Error: ' + req.responseText);
     }
});

{ "fixture": {
    "ID":0,
    "HomeTeam":{
        "ID":1,
        "Name":"Rhondda St FC",
        "Wins":21,
        "Losses":2,
        "Draws":4,
        "GoalsConceded":20,
        "GoalsScored":36,
        "Manager": {
            "ID":1,
            "Name":"Ron Burgundy"
        }
    },
    "AwayTeam": {
        "ID":2,
        "Name":"Mt Pleasant United FC",
        "Wins":18,
        "Losses":5,
        "Draws":3,
        "GoalsConceded":22,
        "GoalsScored":28,
        "Manager": { 
            "ID":2,
            "Name":"Brian Fantana"
        }
    },
    "Date":"02/19/2013 12:00pm"
}}

如果有人能对此有所了解，我们将不胜感激。谢谢

编辑：完全错误（没有CSS）是：


请求错误
请求错误
服务器在处理请求时遇到错误。请参阅有关构造对服务的有效请求的说明

我认为这是因为它不喜欢你约会的格式，即“2013年2月19日12:00pm”。尝试将C#Fixture数据契约中的日期类型更改为字符串，或编辑JS Fixture原型的toJSON方法，以返回一个字符串，格式如“2013-02-19Z”.

什么是完整的错误消息？在末尾添加了错误消息。您是否尝试过调试您的服务方法？我发现请求从未到达该方法，这使我相信服务本身不是问题。您能否在服务器上启用跟踪，以了解服务为什么认为请求不好？另外，您是否看到帮助页面（如错误页面中建议的）以与您的请求进行比较？我尝试更改日期，但没有成功。最终，我只是将Fixture C#类更改为保存团队ID而不是团队对象，现在它可以工作了。这并不是我想做的，但很管用。
