在.NET Core应用程序中使用OData,您可以按照以下步骤进行操作:
using Microsoft.AspNet.OData.Builder;
using Microsoft.AspNet.OData.Extensions;
using Microsoft.AspNetCore.Mvc;
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(options =>
{
options.EnableEndpointRouting = false;
}).SetCompatibilityVersion(CompatibilityVersion.Version_3_0);
services.AddOData();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseMvc(routeBuilder =>
{
routeBuilder.Select().Expand().Filter().OrderBy().MaxTop(100).Count();
routeBuilder.MapODataServiceRoute("odata", "odata", GetEdmModel());
});
}
private static IEdmModel GetEdmModel()
{
ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Product>("Products");
return builder.GetEdmModel();
}
using Microsoft.AspNet.OData;
using Microsoft.AspNetCore.Mvc;
using System.Linq;
public class ProductsController : ODataController
{
private readonly MyDbContext _context;
public ProductsController(MyDbContext context)
{
_context = context;
}
[EnableQuery]
public IQueryable<Product> Get()
{
return _context.Products;
}
[EnableQuery]
public SingleResult<Product> Get([FromODataUri] int key)
{
IQueryable<Product> result = _context.Products.Where(p => p.Id == key);
return SingleResult.Create(result);
}
// 添加其他操作...
}
至此,您已经成功在.NET Core应用程序中使用OData。您可以根据您的实际需求自定义OData控制器和路由,并使用OData查询语言来过滤、排序和分页数据。如果您需要更多关于OData的信息,可以参考以下链接:
