Asp.Net Core odata无法识别控制器中的Get操作方法

如何解决Asp.Net Core odata无法识别控制器中的Get操作方法

我们在Asp.Net Core 3.1上使用了Odata 7.4.1，当我们使用Get操作方法添加新控制器时，它将无法正常工作。

Odata路由构建器：

app.UseMvc(
            routeBuilder =>
            {
                // the following will not work as expected
                // BUG: https://github.com/OData/WebApi/issues/1837
                // routeBuilder.SetDefaultODataOptions( new ODataOptions() { UrlKeyDelimiter = Parentheses } );
                routeBuilder.ServiceProvider.GetRequiredService<ODataOptions>().UrlKeyDelimiter = Parentheses;

                // global odata query options
                routeBuilder.Count();

                routeBuilder.MapVersionedODataRoutes("odata","api/v{version:apiVersion}",modelBuilder.GetEdmModels());
            });

模型配置：

public class ServiceModelConfiguration : IModelConfiguration
{
    /// <summary>
    /// Applies model configurations using the provided builder for the specified API version.
    /// </summary>
    /// <param name="builder">The <see cref="ODataModelBuilder">builder</see> used to apply configurations.</param>
    /// <param name="apiVersion">The <see cref="ApiVersion">API version</see> associated with the <paramref name="builder"/>.</param>
    public void Apply(ODataModelBuilder builder,ApiVersion apiVersion)
    {
        var services = builder.EntitySet<Service>("SM").EntityType;

        services.HasKey(p => p.Id);

        if (apiVersion <= ApiVersions.V1)
        {
            // This is how we maintain backwards compatibility without having to explicitly
            // version our contract api models
            //store.Ignore(p => p.Email);
        }

        // see https://github.com/microsoft/aspnet-api-versioning/tree/master/samples/aspnetcore/SwaggerODataSample
        // for more examples
    }
}

模型类别：

public class Service
{
    public int Id { get; set; }
    public string name { get; set; }
}

Odata安装程序-Api Explorer选项：

options.QueryOptions.Controller<V1.ServicesController>()
                                    .Action(f => f.Get(default))
                                        .Allow(Skip | Count)
                                        .AllowTop(100)
                                        .AllowOrderBy("name");

ServiceController：

 /// <summary>
    /// Gets all services
    /// </summary>
    /// <param name="options">The current OData query options.</param>
    /// <returns>All available stores.</returns>
    /// <response code="200">The successfully retrieved stores.</response>
    [Produces("application/json")]
    [ProducesResponseType(typeof(Service),Status200OK)]
    //[Cached(600)]
    public async Task<IActionResult> Get(ODataQueryOptions<Models.Service> options)
    {
        _logger.LogInformation($"Hit: Stores: Get()");
        
        return Ok(new Service { Id = 123,name = "qqq" });
    }

当我们运行此代码时，会突然打开，但无法识别GET方法，也无法在邮递员中使用：

预期：

获取/ api / v1 /服务

解决方法

问题为实体集名称应指向控制器名称。 在下面的行中修复它： var services = builder.EntitySet（“ Services”）。EntityType;
