Expressjs中的Paypal REST SDK集成不在沙箱中显示事务

Question

router.post('/buy' , ( req , res ) => {
    const amt = req.body.quantity*req.body.price

    /**
     * Paypal payment json to be passed
     */
    const payment_json = {
        "intent": "sale",
        "payer": {
            "payment_method": "paypal"
        },
        "redirect_urls": {
            "return_url": "https://localhost:4200/success",
            "cancel_url": "https://localhost:4200/err"
        },
        "transactions": [{
            "amount": {
                "total": '' + Math.round((amt)*100)/100,
                "currency": "CAD",
                "details": {
                    "subtotal": '' + Math.round((amt)*100)/100,
                    "tax": "0.00",
                    "shipping": "0.00"
                }
            },
            "description": "This is payment description.",
            "item_list": { 
                "items":[
                    {
                        "quantity": req.body.quantity, 
                        "name": "collection", 
                        "price": '' + req.body.price,  
                        "sku": req.body.collid, 
                        "currency":"CAD"
                    }
                ]
            }
        }]
    }

    /**
     * Paypal payment object created
     */
    paypal.paypal.payment.create(payment_json, function (error, payment) {
        if (error) {
            res.status(500).send({message: error})
        } else {
            console.log('payment:', payment)
            for(let i=0; i<payment.links.length; i++) {
                if(payment.links[i].rel === 'approval_url') {
                    res.json({forwardLink: payment.links[i].href});
                }
            }
        }
    });
}); 

我做错了什么？

您使用的是旧的、不推荐使用的v1 SDK。并且缺少必需的“execute”API步骤,该步骤必须在批准后发生,并被重定向到return_url。

您应该切换到使用checkout-nodejs-sdk的当前v2集成。您需要的API调用是“set Up transaction”，然后是批准后的“capture transaction”（捕获transaction），文档记录在这里：https://developer.paypal.com/docs/checkout/reference/server-integration/

用于审批的最佳web流如下:https://developer.paypal.com/demo/checkout/#/patter/server，因为它不涉及重定向，并且将站点加载到后台
