Controller.json 设置 Serialization.ReferenceLoopHandling [英] Controller.json set Serialization.ReferenceLoopHandling

问题描述

有没有办法设置 Controller.Json ReferenceLoopHandling 属性?

is there a way to set Controller.Json ReferenceLoopHandling property?

在解析两端定义导航属性的实体时，当前会导致自引用循环.这个问题通过设置解决了

It is currently causing a self referencing loop when parsing entities with navigation properties defined on both ends. This problem is solved by setting

ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;

有没有办法为 Controller.Json 方法做到这一点?

Is there a way to do this for Controller.Json method?

我找到了这段代码，但它似乎不起作用.

I found this piece of code, but it does not seem to work.

services.Configure<MvcOptions>(option =>
        {
            option.OutputFormatters.Clear();
            var jsonOutputFormatter = new JsonOutputFormatter();
            jsonOutputFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;

            option.OutputFormatters.Insert(0, jsonOutputFormatter);
        });

推荐答案

我认为一个更漂亮的解决方案是在您的 ConfigureServices 中添加 JsonOptions，例如:

I think that a prettier solution for this is to add JsonOptions in your ConfigureServices like:

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