从.net RC2
升级到RTM后,我发现需要为从ArrayPool派生的JsonOutputFormatter的构造
函数提供参数.我如何获得此对象？我正在手动创建JsonOutputFormatter,因为我需要配置ReferenceLoopHandling.
我能找到的其他相关信息是这样的：
https://github.com/aspnet/Mvc/issues/4562
@H_
301_5@public IServiceProvider ConfigureServices(IServiceCollection services)
{
// Add framework services.
services.AddMemoryCache();
services.AddSession();
services.AddMvc();
var formatterSettings = JsonSerializerSettingsProvider.CreateSerializerSettings();
formatterSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
JsonOutputFormatter formatter = new JsonOutputFormatter(formatterSettings,???);
services.Configure<MvcOptions>(options =>
{
options.OutputFormatters.RemoveType<JsonOutputFormatter>();
options.OutputFormatters.Insert(0,formatter);
});
//etc...
}
@H_
301_5@var formatter = new JsonOutputFormatter(formatterSettings,ArrayPool<Char>.Shared);

在评论中：
The JsonOutputFormatter now needs a ArrayPool when creating it,you
can pass in ArrayPool.Shared.
我还注意到ArrayPool上有一个.Create()方法.
@H_
301_5@var formatter = new JsonOutputFormatter(formatterSettings,ArrayPool<Char>.Create());
