如何声明参数作为OData的preFIX [英] How to declare a parameter as prefix on OData

问题描述

使用的WebAPI正常ApiController，我做了如下code定义每个ApiControllers动态地图路径模板：

Using a normal ApiController in WebApi, I made the following code to define a dynamic map route template for every ApiControllers:

config.Routes.MapHttpRoute(
        name: "Sample",
        routeTemplate: "{sessionId}/{controller}"
     );

我要实现类似行为，但每ODataController。
我试过以下code，但它不工作：

I want to achieve a similar behaviour but for every ODataController. I've tried the following code, but it doesn't work:

 config.MapODataServiceRoute(
        routeName: "HSODataRoute",
        routePrefix: "{sessionId}/",
        model: GetEdmModel());

任何想法，这是如何的OData做？我有点新的它和互联网是缺乏这方面的信息。

Any idea how this is made in OData? I'm kinda new to it and the internet is lack of information about this.

要更具体地：{的sessionId}不应该是一个常数，而是用一个GUID值的参数

To be more specific: {sessionId} isn't supposed to be a constant, but a parameter with a Guid value.

推荐答案

一些测试后，我发现，声明MapODataServiceRoute是不够的！
您需要还添加MapHttpRoute此外，由于ODataController从ApiController派生

After a few tests I've found out that declaring MapODataServiceRoute is not enough! You need also to add MapHttpRoute also, since ODataController derives from ApiController

config.Routes.MapHttpRoute(
    name: "Sample",
    routeTemplate: "{sessionId}/{controller}"
 );

config.MapODataServiceRoute(
    routeName: "HSODataRoute",
    routePrefix: "{sessionId}/",
    model: GetEdmModel());

我发现了这一点，因为我删除MapHttpRoute后，我已经开始得到404没有发现，当我加入MapHttpRoute资源可能被发现。

I discovered this because after I removed MapHttpRoute, I've started to get 404 not found, and when I added MapHttpRoute the resource could be found.

更新：

这是我想出解决这个问题的最终解决方案是张贴在这里：传递参数在OData的的WebAPI网址。

The final solution that I've come up to solve this issue was posted here: Pass Parameters in OData WebApi Url.
