使用HttpClient消费odata web api [英] Consume odata web api with a HttpClient

问题描述

嘿伙计们！

我开发了一个支持odata的ASP.NET Web Api（2.2）。 API运行正常，我用fiddler来发布，发布东西，api处理好一切。



现在我正在尝试编写一个消耗API的C＃库。现在我曾经有一个没有odata支持的API，下面的代码工作正常：

Hey guys!
I developed a ASP.NET Web Api (2.2) with odata support. The API works fine, I use fiddler to get, post stuff and the api handles everything fine.

Now I'm trying to write a C# library that consumes the API. Now I used to have a API without odata support and the following code works just fine :

var url = "Support/Tickets";
HttpResponseMessage response = client.GetAsync(url).Result;
if (response.IsSuccessStatusCode)
{
    var list = response.Content.ReadAsAsync<List<Tickets>>).Result;
}

（此处客户端是System.Net.Http.HttpClient对象）



但是，由于我实现了odata解决方案，因此从API返回的JSON发生了变化：

(client here is a System.Net.Http.HttpClient object)

However, since I implemented the odata solution, the JSON returned from the API is changed :

{
  "odata.metadata":"http://url.to/Support/$metadata#Tickets","value":[
    {

    }
  ]
}

现在粗线是新的并且导致线

var list = response.Content.ReadAsAsync< List< Tickets>>）。

失败。我明白这条线路失败的事实，但我无法弄清楚正确处理新JSON响应的方法。我需要使用某种odata解串器吗？



谢谢！

Now the bold line is new and causes the line
var list = response.Content.ReadAsAsync<List<Tickets>>).Result;
to fail. The fact that the line fails I understand, but I can't figure out what way to handle the new JSON response correctly. Do I need to use some kind of odata deserializer or something?

Thanks!
