XmlSerializerInputFormatter已过时-ASP.NET Core 2.1 [英] XmlSerializerInputFormatter is obsolete - ASP.NET Core 2.1

问题描述

我正在使用以下代码接受在我的Core API应用中序列化的XML.

I am using the following to accept XML serialized in my Core API App.

services.AddMvc(options =>
{
    // allow xml format for input
    options.InputFormatters.Add(new XmlSerializerInputFormatter());
}).SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

更新到ASP.NET Core 2.1之后，我收到以下警告:

After updating to ASP.NET Core 2.1 I receive the following warning:

'XmlSerializerInputFormatter.XmlSerializerInputFormatter()'已过时:'此构造函数已过时，将在以后的版本中删除.'

'XmlSerializerInputFormatter.XmlSerializerInputFormatter()' is obsolete: 'This constructor is obsolete and will be removed in a future version.'

处理此问题的新方法是什么?

What is the new way to handle this?

推荐答案

根据

According to the source code, there's a constructor that has not been marked as Obsolete:

public XmlSerializerInputFormatter(MvcOptions options)

此构造函数采用MvcOptions的实例，因此您可以通过现有的options参数:

This constructor takes an instance of MvcOptions, so you can pass through your existing options argument:

services.AddMvc(options =>
{
    // allow xml format for input
    options.InputFormatters.Add(new XmlSerializerInputFormatter(options));
}) ...

从ASP.NET Core 3.0开始，此构造函数是唯一可用的构造函数.那些标记为过时的标记现在已被删除.

As of ASP.NET Core 3.0, this constructor is the only one available. Those that were marked obsolete have now been removed.
