ASP.NET Core 1.0 Web API不返回XML

Question

如何让我的vnext API返回XML和JSON？

我认为使用带有application/xml的content-type可以像以前一样工作.请注意,我尝试使用Accept:application/xml.

但似乎没有.

编辑:

这是我的project.json文件:

{
  "webroot": "wwwroot",
  "version": "1.0.0-*",

  "dependencies": {
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta4",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta4",
    "Microsoft.AspNet.Mvc": "6.0.0-beta4",
    "Microsoft.AspNet.Mvc.Xml": "6.0.0-beta4"
  },

  "commands": {
      "web": "Microsoft.AspNet.Hosting --server     Microsoft.AspNet.Server.WebListener --server.urls http://localhost:5000"
  },

  "frameworks": {
    "dnx451": { },
    "dnxcore50": { }
  },

  "publishExclude": [
    "node_modules",
    "bower_components",
    "**.xproj",
    "**.user",
    "**.vspscc"
  ],
  "exclude": [
    "wwwroot",
    "node_modules",
    "bower_components"
  ]
}

这是我的startup.cs:

public class Startup
{
    // For more information on how to configure your application, visit http://go.microsoft.com/fwlink/?LinkID=398940
    public void ConfigureServices(IServiceCollection services)
    {
        services.ConfigureMvc(options =>
        {
            //options.AddXmlDataContractSerializerFormatter();

            options.InputFormatters.Add(new XmlSerializerInputFormatter());
            options.OutputFormatters.Add(new XmlSerializerOutputFormatter());
        });
        services.AddMvc();
    }

    public void Configure(IApplicationBuilder app)
    {
        app.UseMvc();
    }
}

发布.Net Core 1.0.0后更新了详细信息

startup.cs

public void ConfigureServices(IServiceCollection services)
{
    // Add framework services.
    services.AddMvc(config =>
    {
        // Add XML Content Negotiation
        config.RespectBrowserAcceptHeader = true;
        config.InputFormatters.Add(new XmlSerializerInputFormatter());
        config.OutputFormatters.Add(new XmlSerializerOutputFormatter());
    });

project.json

"dependencies": {
    "Microsoft.AspNetCore.Mvc": "1.0.0",
    "Microsoft.AspNetCore.Mvc.Formatters.Xml": "1.0.0",

默认情况下,Xml格式化程序不包含在Microsoft.AspNet.Mvc程序包中.您需要引用另一个Microsoft.AspNet.Mvc.Xml为此调用的包.

有关如何添加格式化程序的示例:

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    services.ConfigureMvc(options =>
    {
        // This adds both Input and Output formatters based on DataContractSerializer
        options.AddXmlDataContractSerializerFormatter();

        // To add XmlSerializer based Input and Output formatters.
        options.InputFormatters.Add(new XmlSerializerInputFormatter());
        options.OutputFormatters.Add(new XmlSerializerOutputFormatter());
    });
