Question

我有一个问题，我如何从两个实体发帖。我说我已创建类别现在发布我想使用类别帖子作为下拉菜单，然后通过从角度2/4中的数据库中提取类别来发布产品。我将不胜感激任何帮助。先感谢您。请看下面我遇到的问题

我的服务

if(Test-Path HKLM:\SOFTWARE\ODBC\ODBC.INI\user){
Set-Location HKLM:\SOFTWARE\ODBC\ODBC.INI\user
$server = (Get-ItemProperty HKLM:\SOFTWARE\ODBC\ODBC.INI\user).SERVER
if($server-eq "user"){
Set-ItemProperty . SERVER "user.app"
"Set1"}
}
if(Test-Path HKLM:\SOFTWARE\Wow6432Node\ODBC\ODBC.INI\user){
Set-Location HKLM:\SOFTWARE\Wow6432Node\ODBC\ODBC.INI\user
$server = (Get-ItemProperty HKLM:\SOFTWARE\Wow6432Node\ODBC\ODBC.INI\user).SERVER
if($server-eq "user"){
Set-ItemProperty . SERVER "user.app"
"Set2"}
}

下面是我尝试通过预先填充具有id，类别类型为字段的类别中的某些字段来创建产品的组件产品组件

import { Injectable } from '@angular/core';
import { Http, Headers, RequestOptions, Response}  from '@angular/http';
import 'rxjs/add/operator/map';
import 'rxjs/add/observable/throw';
import { Observable }     from 'rxjs/Observable';


@Injectable()

export class myService {

 addProduct(prod){



 const body = JSON.stringify(prod);

 const headers = new Headers({'Content-Type': 'application/json'});


 let Url= "https://localhost/v1/products";

 return this.http.post(Url, body, {headers: headers}).map(res=>res.json())



}


addCat(cat){ 

  const body = JSON.stringify(cat);

 const headers = new Headers({'Content-Type': 'application/json'});


let catUrl= "https://localhost/v1/cat";

 return this.http.post(Url, body, {headers: headers}).map(res=>res.json())


}

 getCat(){
     this.http.get(catUrl).map(res => res.json())
 }
}

html内容就是这个

import { Component, OnInit } from '@angular/core';
import {MyService} from '../myservice'; 

 @Component({


 selector: 'app-report',
  templateUrl: './product.component.html',
  styleUrls: ['./product.component.css']
})

export class ProductComponent implements OnInit {

  cat: any = [];
   proName: any;
   proPrice: any;

  constructor(){}

ngOnInit(){

 this.cat =   this.myService.getCat().subscribe(rescat => this.cat = rescat)
  }

  addProduct(){
       let produc ={
               name: this.proName,
               price: this.proPrice,
               catType: this.cat.name,
               catId : this.cat.id 



           }


       this.myService.addProduct(produc).subscribe(data => 
       console.log(data))
  }

}

我不确定如何在产品创建中包含该类别，我们将不胜感激

从后端预填充表格并在Angular 2/4中发布
