获取“未找到与名为的控制器匹配的类型"Ajax 请求期间的错误消息 [英] Getting the "no type was found that matches the controller named" error message during Ajax Request

问题描述

我已经看到了很多关于此的话题，但不幸的是，我相信每个案例都是不同的案例(或大多数案例)，我真的很希望有专家对我的案例提出意见，因为我无法做出我的即使在阅读了其他一些主题后，代码也能正常工作.

I've seen a lot of topics about this, but unfortunately I believe that each case is a different case (or most of them), and I really would love some experts opinion about my case in particular since I cannot make my code work even after reading through some of the other topics.

情况:我在 jQuery 中使用 Ajax 请求调用我在 WebApi 项目和 MVC 4 应用程序中创建的 WebService 方法.

Situation: I am using an Ajax Request call in jQuery to a WebService method I have created in an WebApi project together with a MVC 4 Application.

我的 WebService 控制器类看起来像默认的，像这样:

My WebService controller class looks like the default, like this:

public class AdditionalInfoController : ApiController
{
    //GET api/AdditionalInfo
    public IEnumerable<string> Get()
    {
        return new string[] { "value1", "value2" };
    }

    //GET api/AdditionalInfo/5
    public string Get(int id)
    {
        return "value";
    }

    //PUT api/AdditionalInfo/5
    public void Put(int id)
    {
        string test = "";
    }
}

来自 jQuery 的我的 Ajax 请求如下所示:

My Ajax Request from jQuery looks like this:

function GetAdditionalInfo(obj)
{
    var request = jQuery.ajax({
        url: "/api/AdditionalInfo/Get",
        type: "GET",
        data: { id: obj.id },
        datatype: "json",
        async: false,
        beforeSend: function () {
        },
        complete: function () {
        }
    })
    .done(function (a,b,c) {
        alert("Additional info was retrieved successfully!");
    })
    .fail(function (a,b,c) {
        alert("An error happened while trying to get the additional info!");
    });
}

我的 WebAPIConfig 文件如下所示:

My WebAPIConfig file looks like this:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

最后但并非最不重要的是，这是我的问题:当我浏览 .fail 中返回的数据变量时，此错误消息不断出现，这就是所写的内容:

And last but not least, this is my problem: this error message keeps appearing when I browse the returned data variable in .fail and this is what is written:

"{
    "Message":"No HTTP resource was found that matches the request URI      'http://localhost:59096/api/AdditionalInfo/Get?id=1'.",
    "MessageDetail":"No type was found that matches the controller named    'AdditionalInfo'."
}"

如果有人能尽快帮助我，我将不胜感激.提前致谢！

I would really appreciate it if someone could help me as soon as possible. Thanks in advance!

推荐答案

好的，我相信我已经知道发生了什么.我不完全确定，但至少我的问题得到了解决.

Ok, so I believe I found out what was going on. I am not entirely certain, but at least my problem got fixed.

只需更改 Ajax 调用中数据"字段中的内容，我就为应用程序中的对象创建了一个类来保存整个数据.似乎由于某种原因，该方法不能具有语法Get(int ID)".

Simply by changing what was inside of the "data" field in the Ajax call and I have created a class for an object in the application to hold the whole data. It seems that for some reason the method could not have the syntax "Get(int ID)".

相反，我做了类似Get(object)"的操作，在 Ajax 请求中类似data: obj.ID"，瞧，它奏效了.

Instead, I did something like "Get( object)" and in the Ajax Request something like "data: obj.ID" and voila, it worked.

此外，由于框架对 REST 方法的名称(Get、Post、Put 和 Delete)很挑剔，我将方法的名称更改为其他名称(例如 Retrieve 或其他名称).

Also, since the framework is picky about the names of the REST methods (Get, Post, Put and Delete), I changed the name of the method to something else (like Retrieve or something).

希望这也能帮助到未来的人.

Hopefully this will help someone in the future as well.
