I am very new to the node js and I get the following error:
Cannot read property 'price' of undefined
I used this package: https://github.com/paypal/PayPal-node-SDK
Code works without line
amount = req.body.price;
But I need to post data
Here is the code:
var paypal = require('paypal-rest-sdk');
var express = require('express');
var app = express();
var amount = 5;
paypal.configure({
'mode': 'sandbox', //sandbox or live
'client_id': 'AV-UFzoT7Ccua-ubSQwUGx96qVq46ySVLTHGPyMiK4CA6HP2gHNW61-cvN__sIoyxQD-xX9zZupCNi',
'client_secret': 'ELAElfR-2pjX5PWJpW3iCW0Yd-WQ_0u2LUk3BDO6v6dcSHgYv1mJG3wg6_gWaR3IwGnVvrZ8pFoRz-'
});
app.post('/pay',(req,res)=>{
amount = req.body.price;
var create_payment_json = {
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"redirect_urls": {
"return_url": "http://localhost:8000/success",
"cancel_url": "http://localhost:8000/pay"
},
"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(payment);
for (let i = 0; i < payment.links.length; i++) {
if (payment.links[i].rel == 'approval_url') {
console.log(payment.links[i].href);
res.redirect(payment.links[i].href);
}
}
}
});
})
Thank you in advance
Also, this is how I post argument price in dart:
String _loadHTML() {
return '''
<html>
<body onload="document.f.submit();">
<form id="f" name="f" method="post" action="http://10.0.2.2:8000/pay">
<input type="hidden" name="ok" value="$price" />
</form>
</body>
</html>
''';
}

Thank You
I have multiple paypal configurations ~15 users
[
...,
{ environment: "sandbox", accKey: "xxxxx", secretKey: "xxxxxxx" },
....
]
I want to instantiate a paypal for each user and return the object
The problem with nodejs is that paypal-rest-sdk export default object, unlike stripe that export stripe
// paypal
const paypal = require("paypal-rest-sdk")
paypal.config({
// config goes here
})
// stripe
const { Stripe } = require("stripe")
const stripe = new Stripe("secret key")
PROBLEM: If I will wrap paypal.configure in for-loop it will overwrite the old config.
You could wrap into your own module and export it, the key here is wrapping paypal into it own scope
// my-paypal-module.js
module.exports = config => {
const paypal = require("paypal-rest-sdk")
paypal.configure(config)
return paypal
}
// main-file.js
const Paypal = require('./my-paypal-module')
const paypal = new Paypal({ /* config */ })
Well I figured it out myself only.
While executing any request, there is optional second parameter in the functions, passing in new configuration object would override the old configuration set by .configure function.
This code has been taken from the official paypal-rest-sdk, original link here
var first_config = {
'mode': 'sandbox',
'client_id': '<FIRST_CLIENT_ID>',
'client_secret': '<FIRST_CLIENT_SECRET>'
};
var second_config = {
'mode': 'sandbox',
'client_id': '<SECOND_CLIENT_ID>',
'client_secret': '<SECOND_CLIENT_SECRET>'
};
//This sets up client id and secret globally
//to FIRST_CLIENT_ID and FIRST_CLIENT_SECRET
paypal.configure(first_config);
var create_payment_json = {
"intent": "authorize",
"payer": {
"payment_method": "paypal"
},
"redirect_urls": {
"return_url": "http://return.url",
"cancel_url": "http://cancel.url"

"item_list": {

},
"amount": {
"currency": "USD",
"total": "1.00"
},
"description": "This is the payment description."
}]
};
// Overriding the default configuration with "second_config"
paypal.payment.create(create_payment_json, second_config, function (error, payment) {
if (error) {
throw error;
} else {
console.log("Create Payment Response");
console.log(payment);
}
});
I want to pass down the variables I create when hitting the /pay route to the /success_api route. Namely I need to pass down 'content', 'productSelectTotal', 'productSubTotal', and 'shipping'. When I trigger /pay the first time, it sets content which is then passed down when I am redirected to '/success', however on all subsequent requests, the value of content, productSelectTotal, productSubTotal, and shipping in the 'success_api' get function remain the same.
Any ideas how to make sure they are being refreshed every time the value of the variables in the parent function is updated?
router.post('/pay', (req, res, next) => {
fs.readFile('ProductDB.json', function (error, data) {
if (error) {
res.status(500).end()
} else {
const productsJson = JSON.parse(data)
console.log(req.body.items)
let content = [];
let productSelect = req.body.items.map(product => {
const itemJson = productsJson.find(function (i) {
return i.productName === product.productName
}).variations.find(function (i) {
return i.id === product.id
})
product.id != null ?
content.push({
// PUSH TO CONTENT HERE
"name": product.productName,
"sku": product.id,
"price": itemJson.variationPrice / 100,
"currency": "USD",
"quantity": product.qty
}) :
false
})
let tariffObj = {
"uk": 3.6,
"us": 11.6,
"rest-of-world": 11.6,
"eu": 8.2
}
let postalCategory = req.body.postalCategory
let postalTarrif = tariffObj[postalCategory]
let shipping = postalTarrif;
let productSelectPrices = content.map(item => item.price * item.quantity);
let productSelectTotal = productSelectPrices.reduce((acc, val) => acc + val, shipping).toFixed(2)
let productSubTotal = productSelectPrices.reduce((acc, val) => acc + val, 0).toFixed(2)

I am scraping medium.com. I am trying to display all the links present on the website.
var url="https://medium.com/";
request(url,function(error,response,html){
if(!error && response.statusCode==200){
var $=cheerio.load(html);
var json={content:"",link:""};
var jsonObjects=[];
var links=$('a');
//console.log(links);
$(links).each(function(i,link){
json.content=$(link).text();
json.link=$(link).attr('href');
jsonObjects.push(json);
});
}
fs.writeFile('Links.json',JSON.stringify(jsonObjects,null,4),function(err){
if(!err){
res.send("File written successfully!!!!")
}
})
})
When I am using this code, only one link is showing up again an again in Links.json file.
[
{
"content": "About",
"link": "https://about.medium.com"
},
{
"content": "About",
"link": "https://about.medium.com"
},
{
"content": "About",
"link": "https://about.medium.com"

},
{
"content": "About",
"link": "https://about.medium.com"
},
{
"content": "About",
"link": "https://about.medium.com"
},
{
I have tried everything but not getting even the links of main page of medium.com
Please help.
It's because you keep on editing the same object and pushing it into the array again and again.
var json={content:"",link:""};
should be inside your each loop.
var url="https://medium.com/";
request(url,function(error,response,html){
if(!error && response.statusCode==200){
var $=cheerio.load(html);
var jsonObjects=[];
var links=$('a');
//console.log(links);
$(links).each(function(i,link){
var content = $(link).text();
var link = $(link).attr('href');
jsonObjects.push({ content: content, link: link });
});
}
fs.writeFile('Links.json',JSON.stringify(jsonObjects,null,4),function(err){
if(!err){
res.send("File written successfully!!!!")
}
})
})
I have a button in my node.js application to buy the product whatever user wants. I want to know how to pass that product details (amount etc) to paypal so that user can pay me via paypal. Is there any in-built library?
Yes. You can use paypal-rest-sdk module.
https://github.com/paypal/rest-api-sdk-nodejs
Here's a sample code taken from here.
var paypal_api = require('paypal-rest-sdk');
var config_opts = {
'host': 'api.sandbox.paypal.com',
'port': '',
'client_id': 'EBWKjlELKMYqRNQ6sYvFo64FtaRLRR5BdHEESmha49TM',
'client_secret': 'EO422dn3gQLgDbuwqTjzrFgFtaRLRR5BdHEESmha49TM'
};
var create_payment_json = {
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"redirect_urls": {
"return_url": "http:\/\/localhost\/test\/rest\/rest-api-sdk-php\/sample\/payments\/ExecutePayment.php?success=true",
"cancel_url": "http:\/\/localhost\/test\/rest\/rest-api-sdk-php\/sample\/payments\/ExecutePayment.php?success=false"
},
"transactions": [{
"amount": {
"currency": "USD",
"total": "1.00"
},
"description": "This is the payment description."
}]
};
paypal_api.payment.create(create_payment_json, config_opts, function (err, res) {
if (err) {
throw err;
}
if (res) {
console.log("Create Payment Response");
console.log(res);
}
});
