Etsy in Angular：将产品添加到访客购物车

Question

I'm trying to add products to my guest cart, passing the guest_id in the url and the listings_id in the body. This is the method:

addToGuestCart(){
    this.http.post(`https://openapi.etsy.com/v2/guests/${this.guest.guest_id}/carts?api_key=my-api-key`, this.product.listing_id)
      .first()
      .subscribe(()=>this.getGuest());
  }

I get this cors error:

XMLHttpRequest cannot load https://openapi.etsy.com/v2/guests/akye30nuit6ua/carts?api_key=my-api-key . No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://localhost:4200 ' is therefore not allowed access. The response had HTTP status code 500.

Answer 1

Input of HTTP POST body is object so you should use : { listing_id: this.product.listing_id }

I read in https://www.etsy.com/developers/documentation/reference/guestcart , I think you should send [listing_id] via url as :

/guests/:guest_id/carts?api_key=my-api-key&listing_id=listing_id_value
