使用 ASP.NET 模型和 AJAX POST 的存储过程的 Web API 问题

Question

我运行遇到参数为空或未提供的问题。以下错误如下：

Procedure or function 'Sp_Warning_Add' expects parameter '@Full_Name', which was not supplied.

我的 ApiController：

    Database_Access_Layer.Db dblayer = new Database_Access_Layer.Db();

    [HttpPost]
    public IHttpActionResult AddWarning([FromBody]WarningData Warning)
    {
        try
        {
            if (!ModelState.IsValid)
            {
                return BadRequest(ModelState);
            }

            dblayer.Add_Warning(Warning);

            return Ok(Warning.licenseNumber);
        }
        catch (Exception e)
        {
            return Ok(e);
        }
    }

我的模型结构：

public class WarningData
{
    public string fullName { get; set; }
    public string licenseNumber { get; set; }
    public string warningDateIssued { get; set; }
    public string warningLocation { get; set; }
    public string warningOfficer { get; set; }
    public string warningDetails { get; set; }
}

我的数据库访问层：

public class Db
{
    // Add Warning Procedure
    SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString);

    WarningData Warning = new WarningData();

    public void Add_Warning(WarningData Warning)
    {
        SqlCommand com = new SqlCommand("Sp_Warning_Add", con)
        {
            CommandType = CommandType.StoredProcedure
        };

        com.Parameters.AddWithValue("@Full_Name", Encoder.HtmlEncode(Warning.fullName));
        com.Parameters.AddWithValue("@Date", Encoder.HtmlEncode(Warning.warningDateIssued));
        com.Parameters.AddWithValue("@Ticket_Details", Encoder.HtmlEncode(Warning.warningDetails));
        com.Parameters.AddWithValue("@Ticket_Unit", Encoder.HtmlEncode(Warning.warningOfficer));
        com.Parameters.AddWithValue("@Ticket_Location", Encoder.HtmlEncode(Warning.warningLocation));
        com.Parameters.AddWithValue("@Ticket_Fine", "0");
        com.Parameters.AddWithValue("@Ticket_Jailtime", "0");
        com.Parameters.AddWithValue("@Ticket_Warrant_Active", "No");
        com.Parameters.AddWithValue("@Ticket_Charges", "Warning");
        com.Parameters.AddWithValue("@License_Number", Encoder.HtmlEncode(Warning.licenseNumber));

        con.Open();
        com.ExecuteNonQuery();
        con.Close();
    }
}

我的存储过程：

CREATE proc Sp_Warning_Add
    @Full_Name NVARCHAR(MAX),
    @Date NVARCHAR(MAX),
    @Ticket_Details NVARCHAR(MAX),
    @Ticket_Unit NVARCHAR(MAX),
    @Ticket_Location NVARCHAR(MAX),
    @Ticket_Fine NVARCHAR(MAX),
    @Ticket_Jailtime NVARCHAR(MAX),
    @Ticket_Warrant_Active NVARCHAR(MAX),
    @Ticket_Charges NVARCHAR(MAX),
    @License_Number NVARCHAR(MAX) 
AS
BEGIN
    INSERT INTO tickets 
    VALUES (@Full_Name, @Date, @Ticket_Details, @Ticket_Unit, @Ticket_Location,
            @Ticket_Fine, @Ticket_Jailtime, @Ticket_Warrant_Active,
            @Ticket_Charges, @License_Number)
END

我的AJAX电话：

$('#createWarningBtn').click(function (event) {
    var warningFormSerialized = jQFormSerializeArrToJson($("#warningForm").serializeArray());
    $.ajax({
        type: "POST",
        url: "/api/Civilian/AddWarning",
        data: JSON.stringify({ Warning: warningFormSerialized }),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        async: true,
        success: function (data) {

        },
        failure: function (data) {

            alert("Message: " + r.Message);
            alert("StackTrace: " + r.StackTrace);
            alert("ExceptionType: " + r.ExceptionType);
        },
        complete: function (data) {
            civTickets(data.responseJSON.d);
            $('#warningForm').dialog('close');
            console.log(data)
        }
    });
    event.preventDefault();
});

值不存在到底是我做错了什么？运行这个 AJAX 对 WebMethod 的调用有效，但是当我以这种方式使用 APIController 时，它不起作用。谢谢您的帮助。

Answer 1

我明白了。它在 AJAX 通话中。

data: JSON.stringify({ Warning: warningFormSerialized }),

应该是：

data: JSON.stringify(warningFormSerialized),
