Javascript 如何使用ajax post方法将复杂对象发送到c#controller？

我正在尝试向mvc控制器post方法发送一个复杂的javascript对象。 每次运行该方法时，我都会收到一个BadRequest响应。它不允许我使用VisualStudio进行调试，只允许使用web开发人员工具进行调试。我与fiddler进行了检查，以查看我的JSON对象似乎与视图模型的顺序相同。谁能帮我一下吗？ 我正在使用Asp.NETCore1.0。如果我需要提供更多信息，请告诉我

以下是我的视图模型：

public class RouteViewModel
    {
        public RouteViewModel() { }
        public List<CheckpointViewModel> Checkpoints { get; set; }
        public int TotalDistance { get; set; }
    } 
 public class CheckpointViewModel
    {
        public decimal Latitude { get; set; }
        public decimal Longitude { get; set; }
    }

接收post的控制器如下所示：

        [HttpPost]
        [ValidateAntiForgeryToken]
        public IActionResult AddRoute([FromBody]RouteViewModel route)
        {
            RouteViewModel newRoute = route;
            if (ModelState.IsValid)
            {
                _context.AddRoute(newRoute.Checkpoints, newRoute.TotalDistance);
                _context.SaveRoute();
                return RedirectToAction("SavedRoutes");
            }
            else
            {
                return BadRequest(ModelState);
            }
        }

以下是我的原始帖子：

根据@I的建议，我在控制器中收集了我的modelstate错误，并将其写入输出窗口，如下所示：

        [HttpPost]
        [ValidateAntiForgeryToken]
        public IActionResult AddRoute([FromBody]RouteViewModel route)
        {
            RouteViewModel newRoute = route;
            if (ModelState.IsValid)
            {
                _context.AddRoute(newRoute.Checkpoints, newRoute.TotalDistance);
                _context.SaveRoute();
                return RedirectToAction("SavedRoutes");
            }
            else
            {
                //Getting errors
                var errors = ModelState.Values.SelectMany(v => v.Errors);
                Debug.WriteLine("Errors found: "+ errors+"\nEnd Errors found");
                return BadRequest(ModelState);
            }
        }

在我的输出窗口中，当我触发控制器时，我收到的是以下内容：

尝试让createObject（）返回以下内容：

function createObject() {
    var routeModel = { Checkpoints: [] ,TotalDistance:totalDistance};
    for (var i = 0; i < markersOrders.length; i++) {
        var latlng = markersOrders[i].getPosition();
        var Checkpoint = {
            'Latitude': latlng.lat(),
            'Longitude': latlng.lng()
        };
        routeModel.Checkpoints.push(Checkpoint);
    }
    return JSON.stringify({route: routeModel});
}

函数createObject（）{
var routeModel={Checkpoints:[]，TotalDistance:TotalDistance}；
对于（var i=0；i

我发现我错在哪里了。我需要将所需的验证令牌与ajax post方法一起发送，或者在控制器中删除“[ValidateAntiForgeryToken]”。我选择后者，因为安全不是我目前的目标。谢谢你的建议@–

你能通过网络分享你的请求json数据是什么样子吗？我相信没有必要使用

json.stringify（）

我添加了原始的fiddler Post数据。我还需要补充什么吗？我对fiddler不太熟悉。@erdinger它不工作会有什么不同吗？试着做两件事：1。州政府怎么说？它是否显示任何错误？2.启用日志记录（例如：控制台）并查看日志是否有任何错误更改**public IActionResult AddRoute（[FromBody]RouteViewModel route）**到public ActionResult AddRoute（RouteViewModel route）我尝试了此更改，但没有结果。我认为ActionResult可以访问与其接口IActionResult相同的函数。嗨，我试过这个。它将检查点数组和整数封装在一个对象中，这很酷，结果几乎没有任何变化。
