带有xml输入的.net Core 2.0 Web API httppost作为null出现

Question

尝试获取.net core 2.0 Web API HttpPost方法以使用xml输入。

预期结果：从Postman调用测试端点时，输入参数（以下代码中的xmlMessage）应具有从Postman HttpPost主体发送的值。

实际结果：输入参数为空。

在Web api项目的startup.cs中，我们具有以下代码：

public class Startup
{
   public Startup(IConfiguration configuration)
   {
      Configuration = configuration;
   }

   public IConfiguration Configuration { get; }

   // This method gets called by the runtime. Use this method to add services to the container.
   public void ConfigureServices(IServiceCollection services)
   {
      services.AddMvc()
      .AddXmlDataContractSerializerFormatters();
   }

   // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
   public void Configure(IApplicationBuilder app, IHostingEnvironment env)
   {
      if (env.IsDevelopment())
      {
         app.UseDeveloperExceptionPage();
      }
      app.UseMvc();
   }
}

在控制器中：

[HttpPost, Route("test")]
public async Task<IActionResult> Test([FromBody] XMLMessage xmlMessage)
{
    return null; //not interested in the result for now
}

XMLMessage类：

[DataContract]
public class XMLMessage
{
    public XMLMessage()
    {
    }

    [DataMember]
    public string MessageId { get; set; }
}

在邮递员标题中：

Content-Type:application/xml

Http Post正文：

<XMLMessage>
  <MessageId>testId</MessageId>
</XMLMessage>

感谢任何可以帮助我指出正确方向的帮助。提前致谢..

启动.cs

using System.IO;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Mvc.Formatters;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

namespace test
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc(config =>
            {
                config.InputFormatters.Add(new XmlSerializerInputFormatter());
            }).AddXmlDataContractSerializerFormatters();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseMvc();
        }
    }
}

控制器.cs

using System.Runtime.Serialization;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;

namespace test.Controllers
{
    [DataContract]
    public class TestClass
    {
        [DataMember]
        public string Message { get; set; }
    }

    [Route("[controller]")]
    public class TestController : Controller
    {
        [HttpPost, Route("test")]
        public async Task<IActionResult> Test([FromBody]TestClass test)
        {
            return Ok("OK");
        }

    }

}

程序.cs

使用 Microsoft.AspNetCore；使用 Microsoft.AspNetCore.Hosting；

namespace test
{
    public class Program
    {
        public static void Main(string[] args)
        {
            BuildWebHost(args).Run();
        }

        public static IWebHost BuildWebHost(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .Build();
    }
}

测试.csproj

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.9" />
  </ItemGroup>
</Project>
