我在这行代码“返回this.http.get('../ data / products.json');”中收到404 not found错误。

其中service.ts文件的路径为“ src \ app \ shared \ services \ product.service.ts”。 json文件的路径为“ src \ data \ products.json”

这是service.ts代码:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';

export interface Product {
  id: number;
  title: string;
  price: number;
  imageUrl: string;
  description: string;
}

@Injectable()
export class ProductService {
  constructor(private http: HttpClient) {}

  getAll(): Observable<Product[]> {
    return this.http.get<Product[]>('../data/products.json');
  }

  getById(productId: number): Observable<Product> {
    return this.http.get<Product[]>('../data/products.json')
      .pipe(
        map(products => <Product>products.find(p => p.id === productId))
      );
  }
}

答案 0 :(得分:1)

尝试将json文件夹放在资产文件夹下,如下所示:

src\assets\mock\products.json

,然后在方法中修改路径:

getAll(): Observable<Product[]> {
    return this.http.get<Product[]>('assets/mock/products.json')
}
