API在POSTMAN上有效,但是Angular API没有出现错误

API在Postman中运行良好,但在角度不佳

我试图从API中获取数据,但收到了此消息has been blocked by CORS policy,但是我添加了扩展名来传递问题,但还是如此。

export class ProductsService {
  url = "http://demo.sylius.com/api/v1/products/";
  httpOptions = {
    headers: new HttpHeaders({
      'Content-Type': 'application/json',
      'Authorization': 'Bearer SampleToken'
    })
  };
  constructor(private http: HttpClient) { }
  GetAllProducts() {
    return this.http.get(this.url, this.httpOptions);
  }
}

  

从原点“ http://demo.sylius.com/api/v1/products/”到“ http://localhost:4200”处对XMLHttpRequest的访问已被CORS策略阻止:对预检请求的响应未通过访问控制检查:预检请求不允许重定向

     

core.js:7187错误HttpErrorResponse {headers:HttpHeaders,status:0,statusText:“ Unknown Error”,url:“ http://demo.sylius.com/api/v1/products/”,ok:false,...}
