问题描述
我发现我的项目在使用ng服务的本地计算机上可以正常工作，但是当我使用ng build prod时，它不会返回模型字段
我使用以下由api node.js填充的模型
export class Tenders {
public licitacion: string
public fecha: string
public finaliza: string
public producto: number
public descrip: string
public cantidad: number
public unidad: string
public costo: number
public ultcompra: string
public proveedor: number
public provenom: string
public estado: number
}
我使用下面的代码填充表格。
async pedirTenders(user) {
if (user) {
// console.log('Tenders')
this.tenderService.getTenders()
.subscribe((resp: Tenders[]) => {
console.log(resp.Tenders)
this.dataSource.data = resp.Tenders
this.dataSource.sort = this.sort
this.dataSource.paginator = this.paginator
this.table.dataSource = this.dataSource
})
}
}
GetHTTP服务
getActives(): Observable<Tenders[]> {
return this.http.get<Tenders[]>(this.url.baseApiUrl + 'tendersactives',this.getHttpOptions())
}
当我在本地计算机上运行ng服务时，它会返回模型中声明的licitacion字段 并可以在下面的控制台屏幕截图中看到
但是当我运行ng --prod时，licitacion字段不会显示为以下屏幕截图
两个请求使用的api相同
package.json的使用方式是

预先感谢您的任何建议
亲切的问候
解决方法
谢谢大家花时间回答我。 但是，将await添加到异步请求后不能解决问题。 我已经更改了get函数，但是“ licitacion”字段和所有与报价相关的文件仍然丢失
async pedirTenders(user) {
if (user) {
let resp: any = await this.tenderService.getTenders().toPromise()
console.log(resp.Tenders)
this.dataSource.data = resp.Tenders
this.dataSource.sort = this.sort
this.dataSource.paginator = this.paginator
this.table.dataSource = this.dataSource
}
这是请求的HTML代码。我试图用一张折叠的行制成一张席子表，该行显示offers子查询。 电线的东西在我的本地机器上一切正常，但在生产环境中却没有。
再次感谢
