Try/Catch/Finnaly with ESLint Expected to return 异步箭头函数末尾的值

Question

我的代码中有这个 ESLint 错误：

function(productId: any): 承诺预期 return 异步箭头函数末尾的值

export const getGooglePlayPayment = async (productId) => {
  await InAppBilling.close();
  try {
    await InAppBilling.open();

    if (!await InAppBilling.isSubscribed(productId)) {
      const details = await InAppBilling.subscribe(productId);
      console.log('You purchased: ', details);
      return details.purchaseState === PAYMENT_STATE.PurchasedSuccessfully;
    }
  } catch (err) {
    console.log(err);
    return false;
  } finally {
    await InAppBilling.consumePurchase(productId);
    await InAppBilling.close();
  }
};

有人可以帮我解决这个问题，而不必禁用 ESLing 规则:)

谢谢

这里的规则是consistent-return.

如果 try 块中的 if 语句未实现，则您没有 returning 任何内容。如果 isSubscribed 调用是真实的，你应该 return 一些东西：

export const getGooglePlayPayment = async (productId) => {
  await InAppBilling.close();
  try {
    await InAppBilling.open();

    if (!await InAppBilling.isSubscribed(productId)) {
      const details = await InAppBilling.subscribe(productId);
      console.log('You purchased: ', details);
      return details.purchaseState === PAYMENT_STATE.PurchasedSuccessfully;
    }
    return 'Already subscribed';
  } catch (err) {
    console.log(err);
    return false;
  } finally {
    await InAppBilling.consumePurchase(productId);
    await InAppBilling.close();
  }
};

（当然，把Already subscribed替换成任何最有意义的。如果你只是想表明交易成功，也许return true。重要的是把它和return false 在 catch.)
