ASP.NET Core发布数组对象JSON [英] ASP.NET Core Posting Array Object JSON

问题描述

我正在尝试将视图中的Object数组发布到控制器，但参数为空，我看到对于一个简单的对象，我需要将[FromBody]放入控制器动作中.

I'm trying to post an array of Object in my view to my controller but params are null i saw that for just a simple object I need to put [FromBody] in my controller action.

这是我的JSON:

{
  "monJour": [
    {
      "openTime": "04:00",
      "closedTime": "21:30",
      "id": "0"
    },
    {
      "openTime": "08:00",
      "closedTime": "17:30",
      "id": "1"
    },
    {
      "openTime": "08:00",
      "closedTime": "17:30",
      "id": "2"
    },
    {
      "openTime": "08:00",
      "closedTime": "17:30",
      "id": "3"
    },
    {
      "openTime": "08:00",
      "closedTime": "17:30",
      "id": "4"
    },
    {
      "openTime": "08:00",
      "closedTime": "17:30",
      "id": "5"
    },
    {
      "openTime": "08:00",
      "closedTime": "17:30",
      "id": "6"
    }
  ]
}

这是我的Ajax请求:

Here is my Ajax Request :

function SendAllDay() {
    var mesJours = {};
    var monJour = [];
    mesJours.monJour = monJour;

    var senddata ='';

    $('div[id^="Conteneur"]').each(function () {
        var idDiv = $(this).attr("id");
        var jour = idDiv.substr(9, idDiv.length - 9);
        var opentps = $("#O" + jour).val();
        var closetps = $("#C" + jour).val();
        var monid = $("#id" + jour).val();

        monJour = {
            openTime: opentps,
            closedTime: closetps,
            id: monid
        }

        mesJours.monJour.push(monJour);
    });

    $.ajax({
        url: '@Url.Action("ReceiveAll")',
        dataType: 'json',
        type: 'POST',
        //data: JSON.stringify(monJours),
        data: JSON.stringify(mesJours),
        contentType:'application/json',
        success: function (response) {
            console.log('ok');
            //window.location.reload();
        },
        error: function (response) {
            console.log('error');
            //alert(response)
            //window.location.reload();
        }
    });
}

这是我的动作:

[HttpPost]
public void ReceiveAll([FromBody]ReceiveTime [] rt) { }

这是我的班级:

public class ReceiveTime
{
    public string openTime { get; set; }
    public string closedTime { get; set; }
    public string id { get; set; }
}

我们将不胜感激:)

推荐答案

与其使用POST相同的结构来建模数据，不如使用ReceiveTime[] rt更好.例如，您可以创建一个如下所示的类:

Instead of using ReceiveTime[] rt, it might be better to model the data according to the same structure that you POST. For example, you could create a class that looks like this:

public class MesJours
{
    public ReceiveTime[] MonJour { get; set; }
}

我不知道MesJours作为一个班级名称是否有意义(我不会说法语)，但是这个想法仍然很明确-您可以根据自己的喜好命名该班级.

I don't know if MesJours makes sense as a class name (I don't speak French), but the idea is still clear - You can name the class whatever you like.

鉴于此，您可以像这样更新控制器:

Given this, you could update your controller like this:

[HttpPost]
public void ReceiveAll([FromBody] MesJours mesJours)
{
    // Access monJour via mesJours.
    var rt = mesJours.MonJour;
}

这将满足ASP.NET MVC模型绑定程序的要求，并应为您提供已发布的数据.这样做还有一个好处，就是可以轻松地容纳您可能想要发布的其他任何属性.

This would satisfy the ASP.NET MVC Model Binder and should give you the data you've POSTed. This also has the added benefit of easily accommodating any additional properties you might want to POST.
