[英]Post files from ASP.NET Core web api to another ASP.NET Core web api
[英]ASP.net core Web API post array as a property
我使用一個數組來存儲問題標簽,但是當我從 Chrome POST 數據時,我沒有在 TagId 數組上收到任何數據。 其他屬性正常,我收到它們 onlu TagId 為null
這是我的代碼:
問題.cs
public partial class Question
{
[Key]
public int Id { get; set; }
...
[Display(Name = "Tags")]
[NotMapped]
public int[] TagId
{
get
{
Some Code Here
}
set
{
Tag = "";
if(value==null)
return;
foreach (var i in value)
{
Tag = i + ",";
}
Tag = Tag.Trim(',');
}
}
[ScaffoldColumn(false)]
public string Tag { get; set; }
...
}
這是帶有虛擬數據Chrome 帖子數據的chrome 帖子,我在 asp.net 帖子數據中收到 null: Visual Studio Trace on Data receive
這是我的控制器郵政編碼:
QuestionsController.cs
[Route("adminapi/[controller]")]
[ApiController]
public class QuestionsController : BaseRControllerWithFile<Question,QuestionAdminRepository>
{
...
public override async Task<ActionResult<Question>> Post(Question entity)
{
return await base.Post(entity);
}
...
}
將問題類更改為:
public class Question
{
private int[] tagId;
private string tag;
[Key]
public int Id { get; set; }
[Display(Name = "Tags")]
[NotMapped]
public int[] TagId
{
get => tagId;
set
{
tagId = value;
tag = "";
if (value == null)
return;
foreach (var i in tagId)
{
tag += i + ",";
}
tag = tag.Trim(',');
}
}
[ScaffoldColumn(false)]
public string Tag => tag;
}
或者正如@Paul 所說; 你可以使用加入:
tag = value != null ? string.Join(',', tagId) : null;
