dodata路由引起了使用版本的API端点

Question

带有相同名称'odata/v {版本：apiversion}/parts'的Attribute路由必须具有相同的模板： 操作：'... v2.controllers.partscontroller.get' - 模板：'odata/v {版本：apiversion}/parts/parts/odata/v {版本：apiversion}/parts' 操作：'... v2.controllers.partscontroller.get' - 模板：'odata/v {版本：apiversion}/parts' 操作：'... v1.controllers.partscontroller.get' - 模板：'odata/v {版本：apiversion}/parts' 操作：'... v1.controllers.partscontroller.get' - 模板：'odata/v {版本：apiversion}/parts'

我的控制器看起来像：

namespace ...Api.Versions.v1.Controllers
{
    [ApiController]
    [ApiExplorerSettings(GroupName = "v1")]
    [ApiVersion("1")]
    [Route("odata/v{version:apiVersion}/[controller]")]
    public class PartsController : ODataController
    {
        [Produces("application/json")]
        [EnableQuery]
        [HttpGet]
        public async Task<IQueryable<Part>> Get()
        {
            ...
        }
    }
}

和

namespace ...Api.Versions.v2.Controllers
{
    [ApiController]
    [ApiExplorerSettings(GroupName = "v2")]
    [ApiVersion("2")]
    [Route("odata/v{version:apiVersion}/[controller]")]
    public class PartsController : ODataController
    {
        [Produces("application/json")]
        [EnableQuery]
        [HttpGet]
        public async Task<IQueryable<Part>> Get()
        {
            ...
        }
    }
}

我的startup.cs具有以下配置：

public void ConfigureServices(IServiceCollection services)
{
   ...
    services.AddControllers()
    .AddOData(options =>
    {
        options.EnableQueryFeatures(maxTopValue: 8000);
        options.TimeZone = TimeZoneInfo.Utc;
    });

    services.AddApiVersioning(options =>
    {
        options.AssumeDefaultVersionWhenUnspecified = true;
        options.DefaultApiVersion = new ApiVersion(1);
        options.ReportApiVersions = true;
        options.ApiVersionReader = new UrlSegmentApiVersionReader();
    })
    .AddMvc()
    .AddOData(options =>
    {
        options.AddRouteComponents("odata/v{version:apiVersion}");
    })
    .AddODataApiExplorer(options =>
    {
        options.GroupNameFormat = "'v'V";
        options.SubstituteApiVersionInUrl = true;
    });
    ...
}

public void Configure(IApplicationBuilder app)
{
    ...
    app.UseRouting();

    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllers();
    });
    ...
}

我的EDM配置如下：

namespace ...Api.Utilities.ModelConfiguration
{
    using Asp.Versioning;
    using Asp.Versioning.OData;
    using Microsoft.OData.ModelBuilder;

    public class PartModelConfiguration : IModelConfiguration
    {
        public void Apply(ODataModelBuilder builder, ApiVersion apiVersion, string routePrefix)
        {
            switch (apiVersion.MajorVersion)
            {
                case 1:
                    ConfigureV1(builder);
                    break;
                case 2:
                    ConfigureV2(builder);
                    break;
                default:
                    ConfigureCurrent(builder);
                    break;
            }
        }

        private void ConfigureV1(ODataModelBuilder builder) =>
            ConfigureCurrent(builder);

        private void ConfigureV2(ODataModelBuilder builder) =>
            ConfigureCurrent(builder);

        private EntityTypeConfiguration<Part> ConfigureCurrent(ODataModelBuilder builder)
        {
            var part = builder.EntitySet<Part>("Parts").EntityType;
            part.HasKey(p => p.IdPart);
            return part;
        }
    }
}

现在，V1和V2模型之间没有区别，这纯粹是用于测试功能。 我相信，按照本页面上的最后一节自动为DI注册上述配置：

我觉得我错过了一些很小的配置，但是努力寻找可能是什么。

您可以从默认控制器base继承您的控制器例如：

[ApiController]
[ApiExplorerSettings(GroupName = "v1")]
[ApiVersion("1")]
[Route("odata/v{version:apiVersion}/[controller]")]
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")]
    [EnableQuery]
    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();
    }
}
