我有一个动作

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

和发送请求的js代码：

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)

        });

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"

以及请求标头：

    Accept  application/json, text/javascript, */*; q=0.01
Accept-Encoding gzip, deflate
Accept-Language en-us,en;q=0.5
Connection  keep-alive
Content-Length  830

如您所见，请求类型是“POST”，我在发送到服务器之前是“Jsoning”数据。但在行动中，我得到了参数的空值。我究竟做错了什么？我已经被困在寻找错误中了

【问题讨论】：

您能向我们展示整个请求吗？有标题？

标签： ajax asp.net-mvc json asp.net-mvc-3 post

【解决方案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。希望这会有所帮助

【讨论】：

谢谢，这篇文章有部分帮助，但字符串数组仍然没有绑定。我会尝试调试以澄清问题所在

【解决方案2】：

您需要在请求中指定数据类型将其发送到服务器。你调用的datatype属性设置服务器响应的格式，设置需要发送到服务器的数据类型需要使用contentType属性

修改用this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'
    });
