旧版asp的json序列化程序设置.net核心应用程序是通过增加AddMvc().AddJsonOptions()来设置的，但我没有在asp.net core 3中使用AddMvc().那么如何设置全局json序列化设置呢？

AddMvc returns an IMvcBuilder implementation, which has a corresponding AddJsonOptions extension method. The new-style methods AddControllers, AddControllersWithViews, and AddRazorPages also return an IMvcBuilder implementation. Chain with these in the same way you would chain with AddMvc:
services.AddControllers()
.AddJsonOptions(options =>
{
// ...
});
Note that options here is no longer for Json.NET, but for the newer System.Text.Json APIs. If you still want to use Json.NET, see tymtam's answer
