.NET7下Odata基础配置

依赖包 Microsoft.AspNetCore.OData     Microsoft.Data.Services

1.Program

//注入OData,启动一些常规linq过滤方法支持
  builder.Services.AddControllers().AddOData(options => options.AddRouteComponents("v1", GetEdmModel()).Filter().Select().Expand());

static IEdmModel GetEdmModel()
{
ODataConventionModelBuilder builder = new();
builder.EntitySet<Address>("AddRess");
return builder.GetEdmModel();
}

//swagger配置

builder.Services.AddSwaggerGen(options =>
{
options.OperationFilter<ODataParameterAttributeFilter>();
});

2.ODataParameterAttributeFilter

照搬这里,其实这里反而是最重要的,我在自己尝试拼装语法的时候总是不成功并且没有提示。

3.Controller

[ApiController]
[Route("/[controller]/")]
public class HomeController : ODataController
{
  [HttpGet, EnableQuery]

  //不要加FromODataUri 这玩意接的参数有毒
  public SingleResult<Address> Get( int Id)
  {
    var result = new List<Address>() { new() { City = "CD", Street = "HG", Id = 1 } };
    return SingleResult.Create(result.AsQueryable());
  }

  [HttpPost, EnableQuery]
  public async Task<IActionResult> Post([FromBody] Address address)
  {
    //add logic
    return Created(address);
  }

  [HttpPut, EnableQuery]
  public async Task<IActionResult> Patch(int Id, Delta<Address> newAddress)
  {
    if (!ModelState.IsValid)
    {
    return BadRequest(ModelState);
    }
    var existingAddress = new List<Address>().FirstOrDefault(s => s.Id == Id);
    if (existingAddress == null)
    {
      return NotFound();
    }

    newAddress.Patch(existingAddress);
    try
    {
      //save
    }
    catch (Exception ex)//DbUpdateConcurrencyException
    {
      if (!NoteExists(Id))
      {
        return NotFound();
      }
      else
      {
        throw;
      }
    }
    return Updated(existingAddress);
  }

  [HttpDelete, EnableQuery]
  public async Task<IActionResult> Delete( int Id)
  {
    var existingAddress = new List<Address>().FirstOrDefault(s => s.Id == Id);
    if (existingAddress == null)
    {
      return NotFound();
    }

    //remove
    return StatusCode(StatusCodes.Status204NoContent);
  }

  private bool NoteExists(int Id)
  {
    return true;
  }
}
