Question

我正在使用ASP.NET核心Web API，并且我不知道如何在将数据插入数据库时返回某些信息，然后在响应类型上显示相关的错误或成功。我创建了一个接口，在其中定义方法，然后在服务中实现接口方法，并将数据插入数据库，然后创建连接到angular的控制器。

接口方法

void AddMurderComplian(Complians complians);

服务方法

public void AddMurderComplian(Complians complians)
{
    var complianMurder = new Complians()
    {
        Dead = complians.Dead,
        Wounded = complians.Wounded,
        CriminalsInvolved = complians.CriminalsInvolved,
        CriminalAppearence = complians.CriminalAppearence,
        VehiclesUsed = complians.VehiclesUsed,
        WeaponsDescription = complians.WeaponsDescription,
        SubType = complians.SubType,
        ApplicationUserId = complians.ApplicationUserId
    };
    try
    {

        _appDbContext.Complians.Add(complianMurder);
        _appDbContext.SaveChanges();
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

控制器

[HttpPost]
[Route("complianMurder")]
public void Post(Complians complian)
{
    _complians.AddMurderComplian(complian);
}

角度

submitMurderInfo()
{
    this.formModelMurder.SubType = "Murder";
    this.formModelMurder.ApplicationUserId = sessionStorage.getItem("Id");
    this.murderService.murderQuestionnaire(this.formModelMurder).subscribe(
        (res: any)=>{
        if (res.succeeded)
        {
            //   this.toastr.success("Welome ");
            //  this.formModelMurder.Dead = '',
            //  this.formModelMurder.Wounded ='',
            //  this.formModelMurder.CriminalsInvolved = '',
            //  this.formModelMurder.CriminalAppearence = '',
            //  this.formModelMurder.VehiclesUsed = '',
            //  this.formModelMurder.WeaponsDescription ='',
            //  this.formModelMurder.SubType = '',
            //  this.formModelMurder.ApplicationUserId = ''
        }
        else
        {
            // this.toastr.error('Sorry Check your complian');
        }
    });
}

我会这样：

public bool AddMurderComplian(Complians complians)
{
  bool succeeded = false;
  var complianMurder = new Complians()
  {
      Dead = complians.Dead,
      Wounded = complians.Wounded, 
      CriminalsInvolved = complians.CriminalsInvolved, 
      CriminalAppearence = complians.CriminalAppearence, 
      VehiclesUsed = complians.VehiclesUsed, 
      WeaponsDescription = complians.WeaponsDescription,
      SubType = complians.SubType,
      ApplicationUserId = complians.ApplicationUserId
  };
  try
  {
      _appDbContext.Complians.Add(complianMurder);
      _appDbContext.SaveChanges();
      succeeded = true;
      return succeeded;
  }
  catch (Exception ex)
  {
      succeeded = false;
      return succeeded;
  }
}

在控制器方法中：

[HttpPost]
[Route("complianMurder")]
public bool Post(Complians complian)
{
    return _complians.AddMurderComplian(complian);
}

成角度：

submitMurderInfo()
{
  this.formModelMurder.SubType = "Murder";
  this.formModelMurder.ApplicationUserId = sessionStorage.getItem("Id");
  this.murderService
    .murderQuestionnaire(this.formModelMurder)
    .subscribe((res: any) => {
      if (res) {
        // Successfully inserted
      } else {
        // this.toastr.error('Sorry Check your complian');
      }
    });
}
