基本API

• 获取存储库中发布的所有产品的列表

 //GET api/items
[ HttpGet ]
public IEnumerable < Item > Get ( ) => itemRepository . Items . ToList ( ) ;

• 通过唯一标识符接收产品

Get(Guid id) { var item = itemRepository.Items.First(g => g.Id == id); if (item != null) return item; return BadRequest(); }">

 //GET api/items/F74349D5-52B4-4A4A-0382-08DA02C684C5
[ HttpGet ( "{id:guid}" ) ]
 public ActionResult < Item > Get ( Guid id )
{
  var item = itemRepository . Items . First ( g => g . Id == id ) ;
  if ( item != null )
    return item ;
  return BadRequest ( ) ;
}

• 根据指定页面接收 15 个产品

Get(int productPage)=>itemRepository.Items .Skip((productPage - 1) * PageSize) .Take(PageSize);">

 //GET api/items/take/2
[ HttpGet ( "take/{productPage:int}" ) ]
public IEnumerable < Item > Get ( int productPage ) => itemRepository . Items
  . Skip ( ( productPage - 1 ) * PageSize )
  . Take ( PageSize ) ;

• 添加新产品或更改现有产品

> Post(Item item) { try { if (item == null) { return BadRequest(); } var repitem = itemRepository.Items.FirstOrDefault(i => i.Id == item.Id); if (repitem != null) { repitem.Description = item.Description; repitem.Category = item.Category; repitem.Price = item.Price; repitem.Name = item.Name; repitem.addedTime = item.addedTime; itemRepository.SaveItem(repitem); } itemRepository.SaveItem(item); return Ok(); } catch (Exception ex) { return StatusCode(StatusCodes.Status500InternalServerError, "Error retrieving data from the database"); } }">

 //POST api/items/add/{item}
[ HttpPost ( "add" ) ]
public async Task < ActionResult < Item > > Post ( Item item )
{
  try
  {
    if ( item == null )
    {
      return BadRequest ( ) ;
    }
    var repitem = itemRepository . Items . FirstOrDefault ( i => i . Id == item . Id ) ;
    if ( repitem != null )
    {
      repitem . Description = item . Description ;
      repitem . Category = item . Category ;
      repitem . Price = item . Price ;
      repitem . Name = item . Name ;
      repitem . addedTime = item . addedTime ;
      itemRepository . SaveItem ( repitem ) ;
    }
    itemRepository . SaveItem ( item ) ;
    return Ok ( ) ;
  }
  catch ( Exception ex )
  {
    return StatusCode ( StatusCodes . Status500InternalServerError , "Error retrieving data from the database" ) ;
  }
}
