Question

我有一个动作

[HttpPost]
    public JsonResult AddLocationsForOrder(List<BuyerOrderLocation> locations, string[] orders)
    {
        // something here
    }

和js代码，发送请求：

data = { locations: serializedLocations, orders: selector.val() };
     $.ajax({
            url: addLocationUrl,
            success: function (responseText) { Core.responceReceived(responseText, null, null); },
            error: function () { Core.showErrorNotification("Sorry, some error occured. Please contact administrator"); },
            async: false,
            type: 'POST',
            dataType: 'json',
            data: JSON.stringify(data)

        });

来自firebug的帖子详情如下：

locations


"[{"id":225,"country":"United States","countryShort":"US","state":"Iowa","stateShort":"IA","city":null,"zipCode":null,"address":"Douglas, IA, USA","latitude":41.9053851,"longtitude":-93.8349976,"bounds":null,"isDeleted":false,"county":"Boone","radius":0},{"id":226,"country":"United States","countryShort":"US","state":"Iowa","stateShort":"IA","city":null,"zipCode":null,"address":"Iowa, USA","latitude":41.8780025,"longtitude":-93.097702,"bounds":null,"isDeleted":false,"county":null,"radius":0}]"


orders


[ "10440" , "10441" , "10442" ]


0  "10440"


1  "10441"


2  "10442"

正如您所看到的，请求类型是“POST”，我在发送到服务器之前“Jsoning”数据。但是在行动中我得到了参数的空值。我究竟做错了什么？我已经坚持寻找错误了

Answer 1

在this文章中，他们解释了如何将复杂的JSON对象发送到ASP.NET。希望这有帮助

Answer 2

您需要在请求中指定数据类型，将其发送到服务器。被调用的datatype属性设置服务器响应的格式，以需要使用contentType属性发送到服务器的格式设置数据类型

修改使用此

调用的ajax

     $.ajax({
        url: addLocationUrl,
        success: function (responseText) { Core.responceReceived(responseText, null, null); },
        error: function () { Core.showErrorNotification("Sorry, some error occured. Please contact administrator"); },
        async: false,
        type: 'POST',
        dataType: 'json',
        data: JSON.stringify(data),
        contentType = 'application/json; charset=utf-8'
    });

您需要在请求中指定数据类型，将其发送到服务器。被调用的datatype属性设置服务器响应的格式，以需要使用contentType属性发送到服务器的格式设置数据类型

将ajax发送到控制器的问题
