将 ArrayPool 对象提供给 JsonOutputFormatter 构造函数
Provide ArrayPool object to JsonOutputFormatter constructor
从 .net RC2 升级到 RTM 后,我发现我需要为派生自 ArrayPool 的 JsonOutputFormatter 的构造函数提供一个参数。我如何获得这个对象?我正在手动更新 JsonOutputFormatter,因为我需要配置 ReferenceLoopHandling。
我能找到的其他相关信息是:
https://github.com/aspnet/Mvc/issues/4562
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...
}
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。
var formatter = new JsonOutputFormatter(formatterSettings, ArrayPool<Char>.Create());
