当我尝试发布到Web API时，接收到的值为null [英] The received value is null when I try to post to my web api

问题描述

我正在使用Web API创建mvc应用程序，我正在使用ajax调用(jquery)在数据库中插入客户详细信息，我正在将调用路由到控制器中的

i am creating mvc application using web api i am inserting the customer detail in database using ajax call(jquery) i am routing my call to

"LeadCustomer/SaveClient"

.在jquery端，我在chrome浏览器中调试了我的代码，我能够填充Data1，它是JSON STRING，但在控制器端，data1为null，不胜感激.json字符串不为null我调试了它

我尝试过的事情:

in my controller. on jquery side i debugged my code in chrome browser i am able to populate Data1 which is JSON STRING but on controller side DATA1 is null any help is appreciated.json string is not null i debugged it

What I have tried:

function insertInformation(name, telephone, email, Gender, birthday, cityid, stateid, Token, stageid, riskProfile, createdBy) {
    //var Data1 = null;
    debugger;
    var Data1 = { CUSTOMER_NAME: name, MOBILE: telephone, EMAIL_ID: email, GENDER: Gender, DOB: birthday, CITY_ID: cityid, STATE_ID: stateid, TOKEN_ID: Token, STAGE_ID: stageid, CREATED_BY: createdBy, UPDATED_BY: Token };
    //Data1 = { CUSTOMER_NAME: name },

    alert(JSON.stringify(Data1));
    $.ajax({
        type: "POST",
        url: apiUrl + "LeadCustomer/SaveClient",
        data: JSON.stringify(Data1),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        cache: false,
        async: true,
        headers: { "cache-control": "no-cache" },
        success: function (obj) {
            var result = obj;

            alert(result);
        },
        error: function (obj) {
            alert("error");
        }
    });
}

public class LeadCustomerEntity
    {
           //Unique Token ID
       
        public string GENDER { get; set; }
        public string CUSTOMER_NAME { get; set; }
        public int MOBILE { get; set; }
        public string EMAIL_ID { get; set; }
        public string DOB { get; set; }
        public int STATE_ID { get; set; }
        public int CITY_ID { get; set; }
        public string CREATED_BY { get; set; }
        public string UPDATED_BY { get; set; }
        public string TOKEN_ID { get; set; }
        
        public string STAGE_ID { get; set; }

    }

[HttpPost]
        [Route("LeadCustomer/SaveClient", Name = "SaveClient")]
        public IHttpActionResult SaveClient([FromBody] LeadCustomerEntity Data1)
        //public IHttpActionResult SaveClient(string CUSTOMER_NAME)
        {
            try
            {
               // SaveConfirmation items = OrderRepository.SaveOrder(Data);
                LeadCustomerMosl item = LeadCustomerRepository.LeadCustomerRegistration(Data1);
               // string item = "heelo world";
                return Ok(item);
            }
            catch (Exception ex)
            {
                Elmah.ErrorSignal.FromCurrentContext().Raise(ex);
                return Ok("Failed");
            }
        }

推荐答案

.ajax({ 类型:" ， url:apiUrl + " ， 数据: JSON .stringify(Data1)， contentType:" ， dataType:" ， 缓存: false ， 异步: true ， 标头:{" :" 无缓存"}， 成功:功能(obj){ var result = obj; 警报(结果); }， 错误:功能(obj){ alert(" )； } }); }

.ajax({ type: "POST", url: apiUrl + "LeadCustomer/SaveClient", data: JSON.stringify(Data1), contentType: "application/json; charset=utf-8", dataType: "json", cache: false, async: true, headers: { "cache-control": "no-cache" }, success: function (obj) { var result = obj; alert(result); }, error: function (obj) { alert("error"); } }); }

public class LeadCustomerEntity
    {
           //Unique Token ID
       
        public string GENDER { get; set; }
        public string CUSTOMER_NAME { get; set; }
        public int MOBILE { get; set; }
        public string EMAIL_ID { get; set; }
        public string DOB { get; set; }
        public int STATE_ID { get; set; }
        public int CITY_ID { get; set; }
        public string CREATED_BY { get; set; }
        public string UPDATED_BY { get; set; }
        public string TOKEN_ID { get; set; }
        
        public string STAGE_ID { get; set; }

    }

[HttpPost]
        [Route("LeadCustomer/SaveClient", Name = "SaveClient")]
        public IHttpActionResult SaveClient([FromBody] LeadCustomerEntity Data1)
        //public IHttpActionResult SaveClient(string CUSTOMER_NAME)
        {
            try
            {
               // SaveConfirmation items = OrderRepository.SaveOrder(Data);
                LeadCustomerMosl item = LeadCustomerRepository.LeadCustomerRegistration(Data1);
               // string item = "heelo world";
                return Ok(item);
            }
            catch (Exception ex)
            {
                Elmah.ErrorSignal.FromCurrentContext().Raise(ex);
                return Ok("Failed");
            }
        }

在发出ajax请求时，您已经写了"url:apiUrl +"LeadCustomer/SaveClient"，"
您错过了提供其URL的地方.

When you are making ajax request you have written "url: apiUrl + "LeadCustomer/SaveClient","
You have missed to provide its url.
