我遇到一些问题，这些问题与使用.NET Core Web API和Entity Framework Core进行自我引用有关.添加时，我的Web API开始令人窒息.包括一些导航属性.

I'm having some issues which I'm guessing are related to self-referencing using .NET Core Web API and Entity Framework Core. My Web API starting choking when I added .Includes for some navigation properties.

我发现在较旧的Web API中似乎是一种解决方案，但我不知道如何为.NET Core Web API实施相同的事情(我仍处于早期学习阶段).

I found what appears to be a solution in the older Web API but I don't know how to implement the same thing for .NET Core Web API (I'm still in the early learning stages).

较早的解决方案将其保留在Global.asax的Application_Start()中:

The older solution was sticking this in the Application_Start() of the Global.asax:

GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Serialize;

我怀疑这是在StartUp的ConfigureService()方法中处理的，但是我对此并不了解.

I suspect this is handled in the StartUp's ConfigureService() method but I don't know much beyond there.

还是有一种更合适的方法来解决此问题?

Or is there a more appropriate way to handle this issue?

推荐答案

好吧...我终于找到了一些参考资料.解决方案是:

Okay... I finally found some reference material on this. The solution is:

public void ConfigureServices(IServiceCollection services) { ... services.AddMvc() .AddJsonOptions( options => options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore ); ... }

我从此处
