C# 如何在asp上使用ajax/jquery将dto数据发布到Web服务

祝你新年快乐

我正在尝试构建一个Jquery对话框模式表单，以便在asp.net页面上为管理控制台创建新用户。目标是将表单数据发送到与DTO和存储过程相关的Web服务。我不明白当我试图将表单发布到我的Web服务时，为什么会出现内部服务器错误。我的web访问是经过严格过滤的，所以搜索起来并不容易（在堆栈上，我没有任何css）

你能帮我解决这个问题吗

谢谢你的帮助

$(document).ready(function() {
    $('#btnsubmit').click(function() {
        var myData = "{'login':'"+$("[id$='logintxt']").val() +"' , 'fname':'"+$("[id$='fnametxt']").val() +"' , 'lname':'"+$("[id$='lnametxt']").val() +"' , 'password':'"+$("[id$='passwordtxt']").val() +"')";
        SendNewUser(myData);
        function SendNewUser(myData) {
            $.ajax({
                type: "POST",
                url: "Webservice.asmx/InsertData",
                data: JSON.stringify({ "users": [myData] }),
                contentType: 'application/json;charset=utf-8',
                dataType: 'json',

                succes: function (result) {
                    alert("Record saved successfully !");
                },
                error: function (XMLHttRequest, textStatus, errorThrown) {
                    alert("Error function : " + XMLHttRequest.toString() + "\n\Status : " + textStatus + "\n\Error : " + errorThrown);
                }
            });
        }

    });
});

还有.asmx

<%@ WebService Language="C#" CodeBehind="~/App_Code/WebService.cs" Class="WebService" %>

在以下几行中调整了代码。看看这是否有帮助

$(document).ready(function() {
$('#btnsubmit').click(function() {
    /*Changed below line*/
    var myData = "[{'login':'"+$("[id$='logintxt']").val() +"' , 'fname':'"+$("[id$='fnametxt']").val() +"' , 'lname':'"+$("[id$='lnametxt']").val() +"' , 'password':'"+$("[id$='passwordtxt']").val() +"'}]";
    SendNewUser(myData);
    function SendNewUser(myData) {
        $.ajax({
            type: "POST",
            url: "Webservice.asmx/InsertData",
            data: JSON.stringify({ "'users': "+ myData }),  /*Changed this line*/
            contentType: 'application/json;charset=utf-8',
            dataType: 'json',

            succes: function (result) {
                alert("Record saved successfully !");
            },
            error: function (XMLHttRequest, textStatus, errorThrown) {
                alert("Error function : " + XMLHttRequest.toString() + "\n\Status : " + textStatus + "\n\Error : " + errorThrown);
            }
        });
    }

});
});

谢谢，经过研究我找到了解决办法。我在Webservice的url上犯了一个错误。

$(document).ready(function() {
$('#btnsubmit').click(function() {
    /*Changed below line*/
    var myData = "[{'login':'"+$("[id$='logintxt']").val() +"' , 'fname':'"+$("[id$='fnametxt']").val() +"' , 'lname':'"+$("[id$='lnametxt']").val() +"' , 'password':'"+$("[id$='passwordtxt']").val() +"'}]";
    SendNewUser(myData);
    function SendNewUser(myData) {
        $.ajax({
            type: "POST",
            url: "Webservice.asmx/InsertData",
            data: JSON.stringify({ "'users': "+ myData }),  /*Changed this line*/
            contentType: 'application/json;charset=utf-8',
            dataType: 'json',

            succes: function (result) {
                alert("Record saved successfully !");
            },
            error: function (XMLHttRequest, textStatus, errorThrown) {
                alert("Error function : " + XMLHttRequest.toString() + "\n\Status : " + textStatus + "\n\Error : " + errorThrown);
            }
        });
    }

});
});
