[英]Angular HttpResponse<boolean> returns boolean value, not the expected HttpResponse
[英]boolean value returns undefined on the client in angular
我有一个 asp.net 核心后端,在那里我通过 api 调用获取数据。 我有这个对象模型:
public class CostGroup
{
public long Id { get; set; }
public string Name { get; set; }
public int Rank { get; set; }
public bool HcPlanning { get; set; }
public bool OtherPlantCost { get; set; }
public bool DirectLabCost { get; set; }
public long CompanyId { get; set; }
public Company Company { get; set; }
}
这个api调用:
[HttpGet("{id}")]
public CostGroup GetCostGroup(long Id)
{
return DataContext.CostGroups.Find(Id);
}
这是 angular 中的相应服务:
getCostGroup(id: number) {
return this.http.get<CostGroup>('api/masterdata/costaccounting/costgroups/' + id);
}
一切正常,我在客户端得到这样的结果:
{"id":24,"name":"ss","rank":123,"hcPlanning":true,"otherPlantCost":true,"directLabCost":true,"companyId":1,"company":null}
如您所见,布尔值被正确识别。 但是如果我想读取布尔值,我会得到未定义。 我以CostGroup
的角度读取CostGroup
对象:
this.service.getCostGroup(e.key).subscribe(costGroup => {
this.costGroup = costGroup;
this.companyId = costGroup.companyId;
this.hcplanning = costGroup.hcplanning;
this.otherplantcost = costGroup.otherplantcost;
this.directlabcost = costGroup.directlabcost;
alert(costGroup.directlabcost);
this.editMode = true;
this.name = costGroup.name;
this.popup.instance.show();
});
所有布尔字段都是未定义的。 为什么? 如何克服这个问题?
您的对象属性是驼峰式的:
"otherPlantCost":true
但是,您以小写形式访问它们:
this.otherplantcost = costGroup.otherplantcost;
您必须在骆驼情况下正确访问它们:
this.otherplantcost = costGroup.otherPlantCost;
