MVC：将对象和整数作为JSON发送到控制器

I'm trying to send a custom object and an integer to my controller action using jQuery AJAX.

我正在尝试使用jQuery AJAX向控制器操作发送自定义对象和整数。

[HttpPost]
public JsonResult GetFilenameSuggestion(Document document, int tradeId)
{
    //do stuff...
}

In my JS, I've tried to create the json sent to the controller in several ways, including:

在我的JS中,我尝试以多种方式创建发送到控制器的json,包括:

var json = JSON.stringify({ document: document, tradeId: tradeId });
//or
var json = { document: JSON.stringify(document), tradeId: tradeId };
//or
var json = { document: document, tradeId: tradeId };

and here's my jQuery AJAX:

这是我的jQuery AJAX:

$.ajax({
        type: "POST",
        dataType: "json",
        contentType: "application/json; charset=utf-8",
        url: "/Document/GetFilenameSuggestion",
        data: json,
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        //do bad stuff...
    },
    success: function (data) {
        //do good stuff...
});

Any suggestions on how to do this? I am getting an internal server error when the ajax posts, and I'm 99% sure it's due to how the arguments are being passed to the controller action.

有关如何做到这一点的任何建议?当ajax发布时,我收到内部服务器错误,我99%肯定这是由于参数如何传递给控制器操作。

Use JSON.stringify to convert your javascript object to it's json string version and specify the contentType as "application/json".

使用JSON.stringify将您的javascript对象转换为它的json字符串版本,并将contentType指定为“application / json”。

The below code should work fine.

以下代码应该可以正常工作。

var model = { document: { DocumentName: "Dummy" }, tradeId: 34 };

$.ajax({
    type: "POST",
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    url: "/Document/GetFilenameSuggestion",
    data: JSON.stringify(model),
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        //do bad stuff...
    },
    success: function(data) {
        //do good stuff...
    }
});

for this action method signature

对于此操作方法签名

[HttpPost]
public JsonResult GetFilenameSuggestion(Document document, int tradeId)
{
    // to do : return some useful JSON data
}
