提供的OData服务文档基本U​​RL中的WebAPI的OData一个斜线 [英] Give OData service document base URL a trailing slash in WebApi OData

问题描述

我如何控制基础URL属性在OData服务文档的根元素？

How can I control the base URL attribute in the root element of an OData service document?

我设置使用的WebAPI，在<一个OData服务href=\"http://msdn.microsoft.com/en-us/library/system.web.http.odata.builder.odataconventionmodelbuilder%28v=vs.111%29.aspx\"><$c$c>System.Web.Http.OData.Builder.ODataConventionModelBuilder和控制器从<一个继承href=\"http://msdn.microsoft.com/en-us/library/system.web.http.odata.odatacontroller%28v=vs.111%29.aspx\"><$c$c>System.Web.Http.OData.ODataController

I'm setting up an OData service using WebApi, the System.Web.Http.OData.Builder.ODataConventionModelBuilder and controllers inheriting from System.Web.Http.OData.ODataController

这一切精美的作品和Excel 2013愉快地访问数据。

It all works beautifully and Excel 2013 happily accesses the data.

问题尝试使用Excel 2010和PowerPivot的出现时。我知道了JSON格式的响应修复的在没有接受头部被发送，但我无法找到与基本URL问题的任何讨论。

The problem arises when trying to use Excel 2010 and PowerPivot. I'm aware of the fix for JSON formatted responses being sent in the absence of an Accept header, but I can't find any discussion of problems with the base URL.

我已经建立了我的ODATA路线与 config.Routes.MapODataRoute（ODATA，ODATA，builder.GetEdmModel（））; 和我打这个时网址我得到℃的响应;服务XML：基地=HTTP：//本地主机/ ODATA的xmlns =htt​​p://www.w3.org/2007/app的xmlns：原子= http://www.w3.org/2005/Atom/＆GT;

I have set up my odata route with config.Routes.MapODataRoute("odata", "odata", builder.GetEdmModel()); and when I hit this URL I get a response of <service xml:base="http://localhost/odata" xmlns="http://www.w3.org/2007/app" xmlns:atom="http://www.w3.org/2005/Atom"/>

Excel 2010中的PowerPivot +读取此URL，并决定，因为在基础URI上没有尾随斜线，应该要求与集合的URI的根，例如的http：//本地主机/产品而不是的http：//本地主机/ ODATA /产品，因为它应该

Excel 2010 + PowerPivot reads this URL and decides that because there is no trailing slash on the base URI, it should request collections with URIs in the root, e.g. http://localhost/Products instead of http://localhost/odata/Products as it should.

我已经访问服务文件的静态版本，修改结尾的斜线添加到基证实了我的怀疑属性值，然后正确的URL请求的收集资源。

I have confirmed my suspicion by accessing a static version of the service document, modified to add the trailing slash to the base attribute value and the correct URL is then requested for the collection resource.

我试图通过ASP.Net WebStack源$ C ​​$ C工作，看看我是否可以覆盖格式化或东西，但迷路了。任何建议将不胜AP preciated。

I've tried working through the ASP.Net WebStack source code to see if I can override a formatter or something, but got lost. Any suggestions would be greatly appreciated.

推荐答案

我和PowerPivot的同样的问题，我设法修复XML：基地与之兼容。这里需要code部分：

I had the same problem with PowerPivot and I managed to fix the xml:base to be compatible with it. Here's the part of the code needed:

class MyODataPathHandler : DefaultODataPathHandler
{
    public override string Link(ODataPath path)
    {
        if (path.PathTemplate == "~")
        {
            return path.ToString() + "/";
        }
        return base.Link(path);
    }
}

和

config.Routes.MapODataRoute("odata", "odata", builder.GetEdmModel(), new MyODataPathHandler(), ODataRoutingConventions.CreateDefault());

自定义ODataPathHandler会增加额外的斜杠的默认路径，这将导致一个xml：基地周围PowerPivot中的bug工作。第二个问题是在PowerPivot的XML数据的预期，而不是​​JSON。 //aspnetwebstack.$c$cplex.com/workitem：对于一个解决方法可以在 HTTP找到/ 820
