在ASP.NET Core 3.1+中,要实现OData动态每请求EDM创建和端点路由,可以使用以下步骤:
首先,确保安装了以下NuGet包:
在Startup.cs文件的ConfigureServices方法中添加以下代码,以配置OData服务和路由:
services.AddControllers().AddNewtonsoftJson();
services.AddOData(opt =>
{
opt.Count().Filter().OrderBy().Expand().Select().SetMaxTop(100)
.AddRouteComponents("odata", GetEdmModel());
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_3_0);
private static IEdmModel GetEdmModel()
{
var builder = new ODataConventionModelBuilder();
// 添加实体集和实体类型
builder.EntitySet("Products");
builder.EntitySet("Categories");
return builder.GetEdmModel();
}
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
endpoints.MapODataRoute("odata", "odata", GetEdmModel());
});
[ApiController]
[Route("odata/[controller]")]
public class ProductsController : ControllerBase
{
private readonly List _products;
public ProductsController()
{
_products = new List
{
new Product { Id = 1, Name = "Product 1", CategoryId = 1 },
new Product { Id = 2, Name = "Product 2", CategoryId = 2 },
// 添加更多产品
};
}
[HttpGet]
[EnableQuery]
public IActionResult Get()
{
return Ok(_products.AsQueryable());
}
[HttpGet("{id}")]
[EnableQuery]
public IActionResult Get(int id)
{
var product = _products.FirstOrDefault(p => p.Id == id);
if (product == null)
{
return NotFound();
}
return Ok(product);
}
// 添加其他操作,如Create,Update,Delete等
}
通过这些步骤,您将能够在ASP.NET Core 3.1+中实现OData动态每请求EDM创建和端点路由。您可以根据自己的需要添加更多的实体集和实体类型,并在控制器中实现相应的操作。
