调研方向

Start by tracing fetchSubscriptions and fetchItems, focusing on how _fetchedItems, _fetchedSubscriptions, and _fetchedProducts are populated and whether consecutive calls overwrite shared state. Confirm the behavior with a project that loads both subscription and in-app-purchase products; done means both product types remain available without polling or manually merging arrays.

描述

I have a situation where I offer two subscriptions and an additional "lifetime" subscription (which is really an in-app purchase, consumable). I may easily be mistaken, but the way the plugin implementation is designed, you can't really offer both subs and purchases because of an overwrite of _fetchedItems when calling both fetchSubscriptions and fetchItems consecutively?

My very hacky workaround is to:

  1. fetchSubscriptions where I normally would
  2. Call a separate method, like loadAll() after that:
  async loadAll() {
      await this.waitForSubscriptions();
      fetchItems(["com.nativescript.whatever.item]);
  }
  1. This will await subscriptions being loaded and waitForSubscriptions returns a promise when there is something in the array (yeah this isn't perfect):
  waitForSubscriptions(): Promise<void> {
      return new Promise<void>((resolve) => {
          const check = setInterval(() => {
              if (this._fetchedSubscriptions.length > 0) {
                  clearInterval(check);
                  resolve();        // now valid, since T is void
              }
          }, 500);
      });
  }
  1. After subscriptions are confirmed, then call fetchItems (see step 2).
  2. Finally merge the two arrays:
    if (this._fetchedSubscriptions.length > 0 && this._fetchedProducts.length > 0) {
        this._fetchedItems = [
            ...this._fetchedSubscriptions,
            ...this._fetchedProducts,
        ];
        console.log('Fetched subscription items:', this._fetchedItems);
    }

It's a little more complicated than this and I'd be happy to share my full code if anyone is curious.
