我尝试了很多次，以至于我在使用braintree-angular和braintree-web并使用angularjs fullstack的时候变得秃顶，但是当我在chekout页面中时，我遇到了令牌错误，并且没有付款选项没有显示...
<div class="container">
<div class="row">
<h1>Cart</h1>
<ngcart-cart template-url="components/ngcart/cart.html"></ngcart-cart>
</div>
<div class="row">enter code here
<h1>Choose a payment method</h1>
<p class="help-block">{{ errors }}</p>
<br>
<div class="col-md-6">
<form>
<braintree-dropin options="paymentOptions">Loading...</braintree-dropin>
<input type="submit" value="Purchase" />
</form>
</div>
</div>
</div>
（我认为Braintree-dropin不再起作用，因为它已弃用）

后来我从Braintree-Angular存储库中发现它不再维护了...所以请有人建议我可以使用另一种方法，因为我浪费了太多时间。
