获取XML中的Web API OData v4的OData目录 [英] Get the OData catalog for Web API OData v4 in XML

问题描述

我正在尝试启动并运行Web API OData V4端点.

I am trying to get a Web API OData V4 endpoint up and running.

我终于做到了(从端点中删除了所有DateTime属性后)，现在实体列表在JSON中.

I got it going finally (after removing all the DateTime properties from my endpoint) and now the listing of the entities is in JSON.

我喜欢JSON，但是我使用LinqPad来测试我的端点.它不了解供稿中列出的实体的JSON.

I love JSON, but I use LinqPad to test my endpoints. It does not understand the JSON for the listing of the entities that are in my feed.

我已经看过，而且似乎找不到找到将其更改回XML的方法，所以我在这里问.

I have looked and can't seem to find a way to change this back to XML, so I am asking here.

是否可以使用XML而不是JSON来提供Web API OData v4提要的实体列表?

推荐答案

很抱歉再次发布另一个答案，但是我的第一个答案太冗长了. 我找到了此链接: V4始终返回Json ，并且可以肯定的是，最后的建议确实有效:

Sorry to post another answer, but my first one was getting too lengthy. I found this link: V4 always returns Json and sure enough, the very last suggestion does work:

在WebAPiConfig中，将命名空间引用添加到:

In WebAPiConfig, add namespace references to:

using System.Net.Http.Formatting;
using System.Web.OData.Formatter;

，然后添加类似内容:

var formatters = ODataMediaTypeFormatters.Create();
config.Formatters.InsertRange(0, formatters);

实体列表现在以xml返回.

The entity listing now gets returned as xml.

不利的一面是，所有响应现在默认为次要的，冗长的xml/atom.

The downside, is now all the responses default to the less preferred, verbose xml/atom.

好处是，现在在v4中满足了$format请求.因此，要返回json，您可以将url发出(不弄乱标题): http://<myodataurl>?$format=application/json;odata.metadata=full(或最小或无)

The upside, is that the $format request is now honored in v4. So to get back to json, you can issue the url (without messing with headers) as: http://<myodataurl>?$format=application/json;odata.metadata=full (or minimal or none)

但是，如前所述，LinqPad仍然无法识别v4模式，并且将无法正确连接到此端点.

However, as stated previous, LinqPad still does not recognize the v4 schema, and will not connect correctly to this endpoint.
