我遇到了类似的问题，对我有用的是我使用了createOrder的基本集成，因为我需要的驻留在客户端中。

https://developer.paypal.com/docs/checkout/integrate/#4-set-up-the-transaction

paypal.Buttons({
createOrder: function(data, actions) {
return actions.order.create({
purchase_units: [{
amount: {
currency_code: "USD",
value: '100.00'
}
}]
});
},
onApprove: function(data, actions) {
return fetch('paypalGetExpressCheckout.html', {
method: 'post'
}).then(function(res) {
return res.json();
}).then(function(details) {
// Show a success message to the buyer
alert('Transaction completed by ' + details.payer.name.given_name + '!');
});
}
}).render('#paypal-button-container');
