将字符串数组发布到.net-core mvc

Problem:

问题：

I am trying to send an array of strings via jquery post but they dont get parsed correctly, all I get is null in the list.

我试图通过jquery post发送一个字符串数组但是它们没有被正确解析，我得到的只是列表中的null。

javascript:

JavaScript的：

var array = [];
array.push("test")
array.push("test2")
array.push("tes3")

$.post("Admin/FilteredKeys", $.param(JSON.stringify({ Ids: array, OnlyActive: true }, true)));

C# Model:

C＃型号：

public class MySearch
{
    public bool OnlyActive { get; set; } = true;
    public List<string> Ids { get; set; }
}

action in controller:

控制器中的动作：

public async Task<IActionResult> FilteredKeys(MySearch filter)
{
    var data = await _service.GetFilteredKeyTypes(filter);
    return View();
}

I've googled and found that the traditional property need to be set to true but it remains the same, i tried this snippet as well:

我用谷歌搜索，发现传统的属性需要设置为true但它保持不变，我也试过这个片段：

$.ajax({
    type: "POST",
    url: "Admin/FilteredKeys",
    data: postData,
    success: function(data){
        alert(data.Result);
    },
    dataType: "json",
    traditional: true
});

This is a .net core project do additional I need to change additional paramaters somewhere?

这是一个.net核心项目我还需要在某处更改其他参数吗？

EDIT:

编辑：

forgott to add that my original attempt was like this:

forgott补充说我的原始尝试是这样的：

$.Admin.worker.postJson("Admin/FilteredKeys", JSON.stringify({ Ids: array, OnlyActive: true }), function (data) {
    var t = "";
});

postJson: function (url, data, callback) {
    $.LoadingOverlay("show");
    $.ajax({
        url: url,
        type: 'POST',
        data: data,
        contentType: 'application/json; charset=utf-8',
        success: function (data) {
            if (callback)
                callback(data);
            $.LoadingOverlay("hide");
        },
        error: function (event, jqxhr, settings, thrownError) {
            //$.helpers.errorHandler($("#fileDialogErrors"), event.responseText);
            $.LoadingOverlay("hide");
        }
    });
}

Since I believe accepted answer is not correct - here is alternative one (similar, but not the same as other answers here). First you need to decorate model with FromBody attribute:

因为我认为接受的答案是不正确的 - 这里是替代的答案（类似，但与此处的其他答案不同）。首先，您需要使用FromBody属性修饰模型：

public async Task<IActionResult> FilteredKeys([FromBody] MySearch filter)
{
    var data = await _service.GetFilteredKeyTypes(filter);
    return View();
}

And ajax call should look like this:

并且ajax调用应该如下所示：

var array = [];
array.push("test")
array.push("test2")
array.push("test3")
 $.ajax({
    type: "POST",
    url: "Admin/FilteredKeys",
    data: JSON.stringify({ Ids: array, OnlyActive: true}),
    contentType: "application/json; charset=utf-8",
    success: function(data){
        // ...
    },
    failure: function(errMsg) {
        // ...
    }
});
