C# 在ASP.NET核心Web API中创建返回OData的enbdpoint

我正在尝试在ASP.NET核心Web API中创建OData端点

我使用该模板创建了一个新的ASP.NET Core Web API，并将Microsoft.AspNetCore.OData包（v7.0.0-beta1）添加到其中（假设需要）

我找不到任何关于如何开始这项工作的文档。如果有人能告诉我如何简单地将默认值控制器转换为返回OData而不是Json，那就太好了

根据您的描述，我建议您可以尝试按照以下步骤创建net core odata web api

1.安装Microsoft.AspNetCore.OData 7.0.0-beta1

2.安装Microsoft.EntityFrameworkCore

3.创建模型类和DBContext类

public class Person
{
    [Key]
    public int Id { get; set; }
    [Required]
    public string Name { get; set; }
    [Required]
    public int Age { get; set; }
}

public class ApplicationDbContext : DbContext
{
    public ApplicationDbContext(DbContextOptions options)
        : base(options)
    {
    }


    public DbSet<Person> Persons { get; set; }

}

5.修改启动类代码，添加OData中间件和OData路由

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.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
        services.AddOData();
        services.AddMvc();

    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //Adding Model class to OData
        var builder = GetEdmModel(app.ApplicationServices);
        builder.EntitySet<Person>(nameof(Person));

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseMvc((routebuilder =>
        {
            routebuilder.MapODataServiceRoute("odata","odata", builder.GetEdmModel());
        }));
    }

    private static ODataConventionModelBuilder GetEdmModel(IServiceProvider serviceProvider)
    {
        var builder = new ODataConventionModelBuilder(serviceProvider);
       
      return builder;
    }
}

公共类启动
{
公共启动（IConfiguration配置）
{
配置=配置；
}
公共IConfiguration配置{get；}
//此方法由运行时调用。请使用此方法将服务添加到容器中。
public void配置服务（IServiceCollection服务）
{
services.AddDbContext
谢谢！这一切工作需要实体框架吗？假设我想使用Dapper或其他ORM来访问我的数据。与@BlakeRivell有相同的问题，我正在尝试将OData与Dapper一起使用。有可能吗？我可以编写自己的数据访问逻辑吗？
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.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
        services.AddOData();
        services.AddMvc();

    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        //Adding Model class to OData
        var builder = GetEdmModel(app.ApplicationServices);
        builder.EntitySet<Person>(nameof(Person));

        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseMvc((routebuilder =>
        {
            routebuilder.MapODataServiceRoute("odata","odata", builder.GetEdmModel());
        }));
    }

    private static ODataConventionModelBuilder GetEdmModel(IServiceProvider serviceProvider)
    {
        var builder = new ODataConventionModelBuilder(serviceProvider);
       
      return builder;
    }
}
