Jquery发布到ASP.NET API控制器

Question

我有一个通过jquery生成的表单:

 $.get("/api/get/getListItems", function (data) {
                var table = "";
                table += "<table>";
                $.each(data, function (y, z) {
                    console.log(z);
                    table += '<tr>';
                    $.each(this, function (k, v) {
                        table += '<td><input type="text" name="' + k + '" id="' + k + '" value="' + v + '" /></td>';
                    });
                    table += '<td><input type="checkbox" name="selected" id="selected" /></td>';

                    table += '</tr>';
                });
                table += '<tr><td><input type="submit" id="submit" name="submit" value="Save To Database" /></td></tr>';
                table += '</table>';
                $('#form').html(table);
            });

并生成此HTML(10行输入字段,7列和1个复选框):http://jsfiddle.net/8zpr2fkL/1/

当我点击提交按钮时,我正在提交表单:

$("#form").submit(function (event) {
        $.post("/api/update/", $("#form").serialize(), alert('success'));
    });

现在我将数据传递给我的ASP.NET API控制器:

[HttpPost]
        public dynamic Post([FromBody]CellModel cells)
        {
                UpdateClass jobs = new UpdateClass();
                return jobs;
        }

这是我的CellModel类:

public class CellModel
    {
        public uint scheduleTaskID { get; set; }
        public string task { get; set; }
        public string baselineDate { get; set; }
        public string scheduledDate { get; set; }
        public string actualDate { get; set; }
        public string finishedDate { get; set; }
        public bool selected { get; set; }

        public override string ToString()
        {
            return scheduleTaskID.ToString();
        }
    }

我的问题是当我点击提交提交数据并在控制器方法上放置一个断点时,单元格数为0,这里有什么我缺少的吗？我试图将输入文本中的所有数据传递给控制器​​.什么都没有传递给我的控制器.我究竟做错了什么？

这是我试图通过jquery $('#form')传递的数据.serialize():

scheduleTaskID=194&task=Permit&baselineDate=6%2F23%2F2005+8%3A00%3A00+AM&scheduledDate=6%2F23%2F2005+8%3A00%3A00+AM&actualDate=6%2F23%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=195&task=Office+Files&baselineDate=7%2F13%2F2005+8%3A00%3A00+AM&scheduledDate=7%2F13%2F2005+8%3A00%3A00+AM&actualDate=7%2F13%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=196&task=Foundation&baselineDate=7%2F27%2F2005+8%3A00%3A00+AM&scheduledDate=7%2F27%2F2005+8%3A00%3A00+AM&actualDate=8%2F13%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=197&task=Framing&baselineDate=8%2F5%2F2005+8%3A00%3A00+AM&scheduledDate=8%2F5%2F2005+8%3A00%3A00+AM&actualDate=8%2F23%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=198&task=Finishes+Exterior&baselineDate=8%2F26%2F2005+8%3A00%3A00+AM&scheduledDate=8%2F26%2F2005+8%3A00%3A00+AM&actualDate=9%2F14%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=199&task=Drywall&baselineDate=9%2F2%2F2005+8%3A00%3A00+AM&scheduledDate=9%2F2%2F2005+8%3A00%3A00+AM&actualDate=9%2F16%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=200&task=Flooring&baselineDate=9%2F1%2F2005+8%3A00%3A00+AM&scheduledDate=9%2F1%2F2005+8%3A00%3A00+AM&actualDate=9%2F20%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=201&task=General+Finish&baselineDate=9%2F12%2F2005+8%3A00%3A00+AM&scheduledDate=9%2F12%2F2005+8%3A00%3A00+AM&actualDate=&finishedDate=&scheduleTaskID=202&task=Final+PDI&baselineDate=10%2F11%2F2005+8%3A00%3A00+AM&scheduledDate=10%2F11%2F2005+8%3A00%3A00+AM&actualDate=&finishedDate=&scheduleTaskID=203&task=Permit&baselineDate=4%2F6%2F2005+8%3A00%3A00+AM&scheduledDate=4%2F6%2F2005+8%3A00%3A00+AM&actualDate=4%2F6%2F2005+8%3A00%3A00+AM&finishedDate=

UPDATE

我改变了:

$("#form").submit(function (event) {
            $.post("/api/update/", $("#form").serialize(), alert('success'));
        });

至

$("#form").submit(function (event) {
        var array = [];
        $('#form > table > tbody  > tr').each(function (elem) {
            var item = {};
            item.scheduleTaskID = $(this).find("td > #scheduleTaskID").val();
            item.task = $(this).find("td > #task").val();
            item.baselineDate = $(this).find("td > #baselineDate").val();
            item.scheduledDate = $(this).find("td > #scheduledDate").val();
            item.actualDate = $(this).find("td > #actualDate").val();
            item.finishedDate = $(this).find("td > #finishedDate").val();
            item.selected = $(this).find("td > #selected").val();
            array.push(item);
        });
        console.log(JSON.stringify(array));
        $.post("/api/update/", JSON.stringify(array), alert('success'), 'json');
    });

在我的控制台日志中,我的数据如下所示:

[{"scheduleTaskID":"203","task":"Permit","baselineDate":"4/6/2005 8:00:00 AM","scheduledDate":"4/6/2005 8:00:00 AM","actualDate":"4/6/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"195","task":"Office Files","baselineDate":"7/13/2005 8:00:00 AM","scheduledDate":"7/13/2005 8:00:00 AM","actualDate":"7/13/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"196","task":"Foundation","baselineDate":"7/27/2005 8:00:00 AM","scheduledDate":"7/27/2005 8:00:00 AM","actualDate":"8/13/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"197","task":"Framing","baselineDate":"8/5/2005 8:00:00 AM","scheduledDate":"8/5/2005 8:00:00 AM","actualDate":"8/23/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"198","task":"Finishes Exterior","baselineDate":"8/26/2005 8:00:00 AM","scheduledDate":"8/26/2005 8:00:00 AM","actualDate":"9/14/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"199","task":"Drywall","baselineDate":"9/2/2005 8:00:00 AM","scheduledDate":"9/2/2005 8:00:00 AM","actualDate":"9/16/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"200","task":"Flooring","baselineDate":"9/1/2005 8:00:00 AM","scheduledDate":"9/1/2005 8:00:00 AM","actualDate":"9/20/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"201","task":"General Finish","baselineDate":"9/12/2005 8:00:00 AM","scheduledDate":"9/12/2005 8:00:00 AM","actualDate":"","finishedDate":"","selected":"on"},{"scheduleTaskID":"202","task":"Final PDI","baselineDate":"10/11/2005 8:00:00 AM","scheduledDate":"10/11/2005 8:00:00 AM","actualDate":"","finishedDate":"","selected":"on"},{"scheduleTaskID":"203","task":"Permit","baselineDate":"4/6/2005 8:00:00 AM","scheduledDate":"4/6/2005 8:00:00 AM","actualDate":"4/6/2005 8:00:00 AM","finishedDate":"","selected":"on"},{}]

在我的ASP.NET API控制器中,我将我的方法更改为:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using MvcApplication1.Models;

namespace MvcApplication1.Controllers
{
    public class UpdateController : ApiController
    {
        [HttpPost]
        public dynamic Post(List<CellModel> cells)
        {
                UpdateClass jobs = new UpdateClass();
                //jobs.PostScheduledTasks(cells);
                return cells;
        }

    }
}

我在Post方法的开头放了一个断点,当它到达断点时,它说单元格Count = 0 ..我看到网络调用,只有在我的post调用后返回false并且响应为空[]为什么数据没有传递给我的控制器,是因为表单是由jquery生成的？

UPDATE

仍然没有解决方案,我看了我的网络电话这个AM,状态代码是301:

Answer 1

不要使用$ .post使用ajax post并将内容类型设置为"application/json; charset = utf-8"

var data = JSON.stringify(array);
$.ajax({
  url:"/api/update/",
  type:"POST",
  data:data,
  contentType:"application/json; charset=utf-8",
  dataType:"json",
  success: function(data){
    console.log(data);
  }
});

问题是你需要对你发送json的网络服务器说,而且不能使用$ .post

这是非常正常的,我也一直在努力(有时我还会忘记),在这里你可以看到你必须使用$ .ajax

Jquery - 如何使$ .post()使用contentType = application/json？
