在 dotnet 6 web wpi 中发布 XML

Question

builder.Services.AddControllers().AddXmlSerializerFormatters(); //I added xml

 public class WeatherForecast
    {
        
        public DateTime Date { get; set; }

       
        public int TemperatureC { get; set; }

        public int TemperatureF => 32 + (int)(TemperatureC / 0.5556);
        
        public string? Summary { get; set; }
    }
    
    public class WeatherForecastList //Class I want to post in xml
    {
       
        public List<WeatherForecast> Forecasts { get; set; }
    }

        [HttpPost] //Experimental method
        public ActionResult<WeatherForecastList> GetWeather([FromBodyAttribute] 
              WeatherForecastList WeatherForecast)
        {
            return Ok(WeatherForecast);
        }

<WeatherForecastList>
   <Forecasts>
      <WeatherForecast>
      .
      .
      </WeatherForecast>
   </Forecasts
</WeatherForecastList>

我目前正在尝试在 dotnet 6 中使用 XML 而不是 JSON 来发布帖子。如果我只发布一个简单的对象，我就可以让它工作。我想了解如何使用嵌套和其他类型的列表发布更复杂的类型。目标是获取 xml 然后返回它。我希望 xml 的结构看起来像上面一样。

您需要在Program.cs中添加xml格式化程序：

builder.Services.AddControllers()
    .AddXmlSerializerFormatters()
    .AddXmlDataContractSerializerFormatters();

并将Produces 属性添加到您的控制器：

[ApiController]
[Route("[controller]")]
[Produces("application/xml")]
public class WeatherForecastController : ControllerBase
{
    private static readonly string[] Summaries = new[]
    {
        "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
    };

    private readonly ILogger<WeatherForecastController> _logger;

    public WeatherForecastController(ILogger<WeatherForecastController> logger)
    {
        _logger = logger;
    }

    [HttpGet(Name = "GetWeatherForecast")]
    public IEnumerable<WeatherForecast> Get()
    {
        return Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),
                TemperatureC = Random.Shared.Next(-20, 55),
                Summary = Summaries[Random.Shared.Next(Summaries.Length)]
            })
            .ToArray();
    }
}

更新

您应该在标头中添加 Content-Type: application/xml，或者如果您是从 swagger 中调用它，只需在此处更改请求正文类型：
