使用jQuery POST和ASP.NET MVC时，Controller参数为NULL [英] Controller parameter NULL when using jQuery POST and ASP.NET MVC

问题描述

我在控制器中处理jQuery GET请求没有问题，但我无法获取任何表单数据到POST。客户端代码段

I have no problems processing jQuery GET requests in a controller, however I cannot get any form data to POST. The client snippet

$.post(url,{name:"John"},function(result){ 
    //process result
});

与控制器相结合，

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Save(string name)
{
    return Json("Success!");
}

在操作方法中检查时将导致name参数为NULL值，而我希望将名称映射到方法参数。此外，此上下文中的所有其他对象（Request.Form）等似乎都是NULL。我可以用 $。get 来做到这一点，但我想我应该做任何带有POST副作用的操作。我正在使用ASP.NET MVC 1.0，jQuery 1.2.6和Internet Explorer 7.

will result in a NULL value for the name parameter when inspected inside the action method, whereas I expected name to be mapped to the method parameter. Also all other objects (Request.Form), etc. in this context seem to be NULL. I can do this with a $.get, but I think I am supposed to do any operations with side-effects with POSTs. I am using ASP.NET MVC 1.0, jQuery 1.2.6 and Internet Explorer 7.

谢谢！

推荐答案

很抱歉，我在页面中有一个$ .ajaxSetup条目，它将默认的contentType覆盖为application / json。

Sorry guys, I had a $.ajaxSetup entry in the page which overrided the default contentType to application/json.

当使用默认的contentType作为如下：

When using the default contentType as follows:

$.ajax({ url,
         type: "POST",
         contentType: "application/x-www-form-urlencoded",
         success: function(result) { alert(result); },
         data: { name: "John" }
        });

它的工作原理是因为默认情况下processData为true，这意味着带有JSON对象的数据条目将被解析为一个字符串（数据：name = John也有效）。

It works because processData is true by default which means the data entry with the JSON object will be parsed into a string (data: "name=John" also works).

很抱歉浪费你的时间:)并感谢Mark关于传递JSON对象的建议，生病了那下一个原因看起来很酷。

Sorry for wasting your time :) and thanks to Mark for the suggestion on passing JSON objects, ill do that next cause it seems very cool.
