我想在我的Web API中同时使用OData和Swagger。我正在运行ASP。NET核心3.1。

我找到了这些文章,一篇支持OData,另一篇支持SwaggerUI

• 启用OData: https://devblogs.microsoft.com/odata/enabling-endpoint-routing-in-odata/
• 启用Swagger: https://www.coderjony.com/blogs/adding-swagger-to-aspnet-core-31-web-api/

然而,我似乎无法同时启用这两个功能。看来我把它们混错了。

这是我目前拥有的代码:

Startup.cs

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllers();
        services.AddOData();
        AddSwagger(services);
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseHttpsRedirection();
        app.UseRouting();
        app.UseAuthorization();

        app.UseSwagger();
        app.UseSwaggerUI(c =>
        {
            c.SwaggerEndpoint("/swagger/v1/swagger.json", "Foo API V1");
        });

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllers();
            endpoints.Select().Filter().OrderBy().Count().MaxTop(10);
            endpoints.MapODataRoute("odata", "odata", GetEdmModel());
        });
    }

    private IEdmModel GetEdmModel()
    {
        var odataBuilder = new ODataConventionModelBuilder();
        odataBuilder.EntitySet<WeatherForecast>("WeatherForecast");

        return odataBuilder.GetEdmModel();
    }

    private void AddSwagger(IServiceCollection services)
    {
        services.AddSwaggerGen(options =>
        {
            var groupName = "v1";

            options.SwaggerDoc(groupName, new OpenApiInfo
            {
                Title = $"Foo {groupName}",
                Version = groupName,
                Description = "Foo API",
                Contact = new OpenApiContact
                {
                    Name = "Foo Company",
                    Email = string.Empty,
                    Url = new Uri("https://example.com/"),
                }
            });
        });
    }
}

当我去的时候,它就起作用了https://localhost:44363/odata/weatherforecast 但当我尝试加载Swagger界面时,显示如下:

它什么都没显示!

这是我的控制器:

控制器

[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
    private static readonly string[] Summaries = new[]
    {
        "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
    };
    
    [EnableQuery]
    public IEnumerable<WeatherForecast> Get()
    {
        var rng = new Random();
        return Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Id = Guid.NewGuid(),
                Date = DateTime.Now.AddDays(index),
                TemperatureC = rng.Next(-20, 55),
                Summary = Summaries[rng.Next(Summaries.Length)]
            })
            .ToArray();
    }
}
