.NET 4.8 ASP.NET Swagger Swagger swashbuckle请求包含一个实体主体，但没有内容类型的标头。媒体类型应用程序/不支持八位钟

Question

您好，我在配置/测试 swashbuckle/Swagger 5.6.0使用.NET Framework 4.8 （asp.net [不是ASP.NET Core！]）

测试从Webui Swagger抛出了一个错误。

与Postman进行相同的操作是：

• content -type：“ application/json” - ok

• content-type：“ application/ocet-stream” - 相同错误

响应主体错误：

Message: "The request contains an entity body but no Content-Type header. The inferred media type 'application/octet-stream' is not supported for this resource.",
ExceptionMessage: "No MediaTypeFormatter is available to read an object of type 'SomeParams' from content with media type 'application/octet-stream'.",
ExceptionType: "System.Net.Http.UnsupportedMediaTypeException",
StackTrace: "   w System.Net.Http.HttpContentExtensions.ReadAsAsync[T](HttpContent content, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)\r\n   w System.Web.Http.ModelBinding.FormatterParameterBinding.ReadContentAsync(HttpRequestMessage request, Type type, IEnumerable`1 formatters, IFormatterLogger formatterLogger, CancellationToken cancellationToken)"

缺少请求内容类型标头的问题，我无法在SwaggerWebui内正确设置它。

没有在Asp.net swashbuckle中产生/消费属性，因此我按照说明在以下说明中手动添加它们（customAttribute + CustomFilters + CustomFilters +注册）。 但是它不起作用，参数内容类型combobox却没有出现。

我还尝试了编辑 webapiconfig.cs 带有/没有全局/正常格式的添加/清算支持的介质类型等。

    //config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new System.Net.Http.Headers.MediaTypeHeaderValue("application/json"));

    var mediaType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/json");

    var formatter = new System.Net.Http.Formatting.JsonMediaTypeFormatter();
    formatter.SupportedMediaTypes.Clear();
    formatter.SupportedMediaTypes.Add(mediaType);

    
    config.Formatters.Clear();
    config.Formatters.Add(formatter);

    var jsonFormatter = new System.Net.Http.Formatting.JsonMediaTypeFormatter();
    jsonFormatter.SupportedMediaTypes.Clear();
    jsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/json"));

    GlobalConfiguration.Configuration.Formatters.Add(jsonFormatter);

    config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/json"));
    config.Formatters.JsonFormatter.SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/xml"));

样品控制器代码：

using System.Collections.Generic;
using System.Linq;
using System.Web.Http;
namespace MainClass
{
    public class xxx_V1Controller : ApiController
    {
        [HttpGet]
        [SwaggerConsumes("application/json")]
        [SwaggerProduces("application/json")]
        [Route("api/xxx_V1/GetAll/", Name = "xxx_V1_GetAll")]
        public Rxxx_V1 GetAll(SomeParamsXyz)
        {
            return AuthorizationController.MainClass.yyy_GetAll_V1(SomeParams xyz);
        }

        [HttpGet]
        [Route("api/xxx_V1/GetAll2/", Name = "xxx_V1_GetAll2")]
        public Rxxx_V1 GetAll2(SomeParams xyz)
        {
            return AuthorizationController.MainClass.yyy_GetAll2_V1(SomeParams xyz);
        }
    }
}

SomeParams类

public class SomeParams : IXyz, IFilters
{
   public string XXX { get; set; }
   public bool GetCountOnly { get; set; }
   public bool YYY{ get; set; }
   public LoadOptions Options { get; set; }
   public List<Filter> Filters { get; set; }
}

我找到了一个网站，说Swashbuckler团队决定不支持尸体接听电话。我尝试了以上所有解决方案，但没有一个对我有用。对我来说，解决方案是将动作更改为帖子。抱歉，我没有讨论的链接。但是这是Github报告的错误，但已关闭。 https://github.com/swagger.com/swagger-appi-appi/swagger-appi/swagger/swagger-ui/issues/- 5388
