网页API 2：4 OData的：操作返回404 [英] Web API 2: OData 4: Actions returning 404

问题描述

我有一个的OData V4 操作方法，它不能正常工作;不过要注意的是在的OData V3 工作正常（我明明在尝试更新我的项目过程中）

I have an OData v4 action method which is not working; note however that it was working fine in OData v3 (I am obviously in the process of trying to update my project)

OData的行动方式：

[HttpPost]
public Translation Translate(ODataActionParameters parameters)
{
    // Implementation
}

配置：

ODataModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Page>("Pages");
//etc (Other Entity Sets)

var pageEntityType = builder.EntityType<Page>();
var translateAction = pageEntityType.Collection.Action("Translate");
translateAction.Parameter<Guid>("pageId");
translateAction.Parameter<string>("cultureCode");
translateAction.Returns<Translation>();

//etc (Other Actions)

var route = config.MapODataServiceRoute("OData_CMS", "odata/cms", builder.GetEdmModel());

客户端AJAX调用：

var data = {
    pageId: $("#CultureSelector_PageId").val(),
    cultureCode: $("#CultureSelector_CultureCode").val()
};

$.ajax({
    url: "/odata/cms/Pages/Translate",
    type: "POST",
    contentType: "application/json; charset=utf-8",
    data: JSON.stringify(data),
    dataType: "json",
    async: false
})
.done(function (json) {
    //etc

我想看看是否有什么改变了关于安装在4版本的OData行动，但似乎（指同一：<一href=\"http://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/odata-v4/odata-actions-and-functions\"相对=nofollow>动作和功能的OData V4使用的ASP.NET Web API 2.2 ）

修改

我发现的OData V4 使用默认命名空间并实现了，具体如下：

I found out that OData v4 uses a Default namespace and implemented that, as follows:

首先，只是通过改变我的AJAX调用：

Firstly, just by changing my AJAX call to:

URL：/odata/cms/Pages/Default.Translate，

这没有工作，所以我也补充道：

That didn't work, so I also added:

[ODataRoute（Default.Translate）] 和

[EnableQuery（AllowedQueryOptions = AllowedQueryOptions.All）]

我的行动，按照这个链接的说明：的http://damienbod.word$p$pss.com/2014/06/16/web-api-and-odata-v4-crud-and-actions-part-3/..

to my action, as per the instructions at this link: http://damienbod.wordpress.com/2014/06/16/web-api-and-odata-v4-crud-and-actions-part-3/..

也没有工作。我已经按照步骤的信......无论我是盲目的，在这里失去了一些东西，或有与最新版本的一个严重的问题的OData 为的Web API 。

Also not working.. I have followed the steps to the letter... either I'm being blind and missing something here or there's a serious problem with the latest version of OData for Web API.

推荐答案

嗯，这是近一年这个问题，我真的试图移动到的OData V4 再次有同样的问题了。我忘了我原来的问题在这里，并要求一个新的，然后找到了答案。请参见的OData v4的函数总是返回更多细节404 。我很高兴地说，所有目前运作良好。

Well, it was almost a year after this question that I actually tried moving to OData v4 again and had the same problem. I forgot about my original question here and asked a new one and then found the answer. See OData v4 Function always returns 404 for more details. I'm glad to say all is working well now.
