Question

我遇到TypeScript错误：

类型'（data：Products）=> void'的参数不能分配给类型'（value：Products []）=> void'的参数。参数“数据”和“值”的类型不兼容。类型“产品[]”不可分配给类型“产品”。类型'Products []'中缺少属性'id'。

这是我的模式：

export class Products {
  id: number;
  prodImage: any;
  catid: number;
  catId: number;
}

这是我得到错误的ts代码：

import { Component, OnInit } from '@angular/core';
import { Router, Params, ActivatedRoute  } from '@angular/router';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import {Products } from '../Admin/products/products';
import {ProductsService } from '../Admin/products/products.service';


@Component({
  selector: 'app-cart',
  templateUrl: './cart.component.html',
  styleUrls: ['./cart.component.css']
})
export class CartComponent implements OnInit {
  sess_id: any;
  prods: Products;
  cartList: Products;

  constructor(
    private router: Router,
    private productsService: ProductsService,
    private routes: ActivatedRoute,
  ) { }

  ngOnInit() {
    this.sess_id = localStorage.getItem('sess_key');

    this.productsService.viewCart(this.sess_id)
    .subscribe((data: Products) => {      //getting error over here
      this.cartList = data;
      console.log(this.cartList);

    });}}

我要去哪里错了？预先感谢

您正在从服务而不是Products元素中获取Products数组。将cardList设置为：cartList :Products[]

类型'（data：Products）=> void'的参数不能分配给类型'（value：Products []）=> void的参数
