uni.requestPayment支付成功，且回调成功，但是没有调用success和fail中的回调函数

分类：uni-app

uni.requestPayment执行完了，

点击“完成后”，

没执行success或fail回调，又返回到了

this.$api.request.alipayApp({
orderId: this.payId,
totalAmount: this.order.money
}, res => {
if (res.success === true) {
let alipayForm = res.data;
uni.requestPayment({
provider: 'alipay',//支付宝支付
orderInfo: alipayForm,
success: function (res) {
this.$api.msg(res);
setTimeout(() => {
uni.redirectTo({
url: '/pages/money/paySuccess'
});
}, 1000);
},
fail: function (err) {
this.$api.msg(err);
setTimeout(() => {
uni.redirectTo({
url: '/pages/order/order'
});
}, 1000);
},
})
} else {
this.$api.msg(res.data);
}
});
