如何解决如何将Node.js应用程序托管到Firebase托管和Paypal SDK和Flutter
嗨,大家好,我正在使用扑扑的Firebase Cloud Firestore开发食品交付应用程序,我想在我的应用程序中使用Paypal付款方式来结帐订单,所以当我使用我的应用程序时,我的node.js的Paypal SDK运行良好要结帐单, 我现在遇到的问题是他拥有http://10.0.2.2:8000/pay的贝宝结帐的网址,该网址仅适用于模拟器,我想要的解决方案是使用Firebase托管此网址,以便为实际设备工作,此问题的任何帮助或者,如果您有任何想法,我将不胜感激地告诉我, 顺便说一句,我是移动应用程序开发人员的新手
这是我在app.js中的代码
var paypal = require("paypal-rest-sdk");
var express = require("express");
var amount = 0; var app = express();
var bodyParser = require("body-parser");
app.use(
bodyParser.urlencoded({
extended:false
}) ); app.use(bodyParser.json())
paypal.configure({
'mode': 'sandBox',//sandBox or live
'client_id': 'client id here','client_secret': 'secret key here' });
app.post("/pay",(req,res)=>{
console.log(req.body);
amount = req.body.price;
var create_payment_json = {
"intent": "sale","payer": {
"payment_method": "paypal"
},"redirect_urls": {
"return_url": "http://10.0.2.2:8000/success","cancel_url": "http://cancel.url"
},"transactions": [{
"item_list": {
"items": [{
"name": "item","sku": "item","price": amount,"currency": "USD","quantity": 1
}]
},"amount": {
"currency": "USD","total": amount
},"description": "This is the payment description."
}]
};
paypal.payment.create(create_payment_json,(error,payment)=> {
if (error) {
throw error;
} else {
console.log("Create Payment Response");
console.log(payment);
for(let i = 0 ; i < payment.links.length ; i++){
if(payment.links[i].rel == 'approval_url'){
res.redirect(payment.links[i].href);
}
}
}
}); })
app.get("/success",res)=>{
var execute_payment_json = {
"payer_id": req.query.PayerID,"transactions": [{
"amount": {
"currency": "USD","total": amount
}
}]
};
var paymentId = req.query.paymentId;
paypal.payment.execute(paymentId,execute_payment_json,function (error,payment) {
if (error) {
console.log(error.response);
throw error;
} else {
console.log("Get Payment Response");
console.log(JSON.stringify(payment));
}
}); })
app.listen(8000,"127.0.0.1",res)=>{
console.log("server started") });
