How to POST a request using data from console.log in the URL

I am receiving a response code which I receive as follows:
function(res) {
console.log("Response from the authorize call:")
console.log(res)
The console.log(res) returns the following:
approved: true
​
authorization_token: "sometoken"
​
finalize_required: false
​
show_form: true
I want to use the authorization_token to send a POST request I have tried the following:
function(res) {
console.log("Response from the authorize call:")
console.log(res)
var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");
myHeaders.append("Authorization", "Basic mypw-usn");
var raw = JSON.stringify({
"intent": "buy",
"purchase_country": "GB",
"purchase_currency": "GBP",
"locale": "en-GB",
"order_amount": 10,
"order_tax_amount": 0,
"order_lines": [{
"type": "physical",
"reference": "19-402",
"name": "Battery Power Pack",
"quantity": 1,
"unit_price": 10,
"tax_rate": 0,
"total_amount": 10,
"total_tax_amount": 0
}],
"merchant_urls": {
"confirmation": "http://localhost:8888/jcart/mypage1.php",
"authorization": "http://localhost:8888/jcart/mypag1e.php"
}
});
var requestOptions = {
method: 'POST',
headers: myHeaders,
body: raw,
redirect: 'follow'
};
fetch("https://api.example//payments/v1/authorizations/res.authorization_token/order", requestOptions)
.then(response => response.text())
.then(result => console.log(result))
.catch(error => console.log('error', error));
}
The error I get is TypeError: NetworkError when attempting to fetch resource.
I think I am not showing the res.authorization_token correctly in the fetch url, however I do not know how to do this correctly.
Any help welcome

Lambda Times Out Writing to DynamoDB

I have a simple function that puts an item into the database. I have enabled a role that has a policy attached to allow puts for this table.
Here is the code below. I have even tired hard coding all the information still it times out. I have also tried increasing the timeout to 30 seconds and the Memory to 512 MB but it still just times out. any help would be greatly appreciated.
const AWS = require(`aws-sdk`);
AWS.config.update({region: `eu-east-2`});
const dynamo = new AWS.DynamoDB.DocumentClient();
exports.handler = function(event, context, callback){
var TableName ="MyFirstExamAnswers";
var Item = {};
Item["Student"] = event.params.Student;
Item[event.params.Question] = event.params.Answer;
console.log("theItem: "+ JSON.stringify( Item));
dynamo.put({TableName,Item}, function (err, data) {
if (err) {
console.log(`error`, err);
callback(err, null);
} else {
var response = {
statusCode: 200,
headers: {
'Access-Control-Allow-Methods': `GET,POST,OPTIONS`,
'Access-Control-Allow-Origin': `*`,
'Access-Control-Allow-Credentials': `true`
},
body: JSON.stringify(data),
isBase64Encoded: false
};
console.log(`success: returned ${data.Item}`);
callback(null, response);
}
});
};
With the following policy attached to the role that the Lambda is running under

Expressjs Post-request is not getting recognized | 404-Error

I want to implement paypal to my website, but I am stuck with this. Always when I try to do a post request (also tried with postman), I dont get an answer which is just the normal 404 error-page. The console is showing no error, so I guess the post request is not getting recognized.
What could be the problem and how can I fix it?
server.js
//payment
app.post("/pay", (req, res) => {
// payment data
const create_payment_json = {
"intent": "sale",
"payer": {
"payment_method": "paypal"
},
"redirect_urls": {
"return_url": "http://localhost:3000/success",
"cancel_url": "http://localhost:3000/cancel"
},
"transactions": [{
"item_list": {
"items": [{
"name": "product1",
"sku": "001",
"price": "350.00",
"currency": "USD",
"quantity": 1
}]
},
"amount": {
"currency": "USD",
"total": "350.00"
},
"description": "test"
}]
};
// create payment
paypal.payment.create(create_payment_json, (error, payment) => {
if(error) {
console.log("payment not successful");
console.log(error)
} else {
console.log("payment successful");
console.log(payment);
}
})
})
products.ejs
<form action="/pay" method="post">
<input type="submit" value="add to cart" onclick="window.location.href='/pay'"/>
</form>

Couple of things you need to make sure
Make sure you are sending the post request to the correct port, just incase your express server isn't hosting the actual site as well. If it is then don't worry about the port
You can use js to send the request to prevent the page from refreshing.
const form = document.querySelector('form')
form.addEventListener('submit', async function(e) {
e.preventDefault()
const port = 3000 //make sure this is the port your express erver is listening on
const formData = new FormData(e.target)
const itemId = formData.get('itemId')// You can store the items id in the name attribute of an input
const response = await fetch(`http://localhost:${port}/pay`, {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({itemId})
})
})
const data = await response.json()
console.log(data) // The response you would get from the server

Slack interactive message getting invalid_payload for response_url sent back

I've been doing some work with the Slack API and with their
interactive messages
I post a message with the interactive message attachment here:
export const postMessage = (msg, channel) => {
request({
method: 'POST',
uri: 'https://slack.com/api/chat.postMessage',
headers: {
'content-type': 'application/json;charset=UTF-8',
Authorization: `Bearer ${process.env.SLACKTOKEN}`,
},
body: JSON.stringify({
token: process.env.SLACKTOKEN,
attachments: [
{
"text": "",
"fallback": "If you could read this message, you'd be choosing something fun to do right now.",
"color": "#3AA3E3",
"attachment_type": "default",
"callback_id": "command_selection",
"actions": [
{
"name": "command_list",
"text": "Choose a command",
"type": "select",
"options": [
{
"text": "Register Team",
"value": "registerTeam"
},
{
"text": "Edit Team",
"value": "editTeam"
},
{
"text": "Get By Url",
"value": "getByUrl"
},
{
"text": "Report Issue",
"value": "reportIssue"
},
{
"text": "Find Team",
"value": "findTeam"
},
{
"text": "List Teams",
"value": "listTeams"
}
]
}
]
}
],
text: msg,
channel,
as_user: true,
})
}, (err, res, body) => {
if (err) {
console.log('error posting msg: ', err);
} else {
console.log('post message to channel: ', body);
}
})
}
Slack then sends a POST request to this URL with a response_url parameter in their payload. This is where I'm getting the payload from in my code:
api.post('/interactivity', (req, res) => {
const { body } = req;
const { payload } = body;
const parsedPayload = JSON.parse(payload)
res.send(parsedPayload.response_url)
var message = {
"text": payload.user.name+" clicked: "+payload.actions[0].name,
"replace_original": false,
}
util.sendMessageToSlackResponseURL(parsedPayload.response_url, message)
})
export const sendMessageToSlackResponseURL = (responseURL, JSONmessage) => {
var postOptions = {
uri: responseURL,
method: 'POST',
headers: {
'content-type': 'application/json'
},
json: JSONmessage
}
request(postOptions, (error, res, body) => {
if (error){
console.log(error)
} else {
console.log('post message to channel: ', body);
}
})
}
For some reason though, the response_url is giving an invalid_payload error when I click on the link and I can't figure out if its the payload I'm sending in the original message I posted or something's up with the POST request that Slack sent

The issue is with utility method on line json: JSONmessage which should be body: JSONmessage
Updated code,
export const sendMessageToSlackResponseURL = (responseURL, JSONmessage) => {
var postOptions = {
uri: responseURL,
method: 'POST',
headers: {
'content-type': 'application/json'
},
body: JSONmessage
}
request(postOptions, (error, res, body) => {
if (error){
console.log(error)
} else {
console.log('post message to channel: ', body);
}
})
}
Hope this works!

FCM data messages doesn't load in firefox

I am working on cloud messaging using Web FCM. When I send a notification with title and body, both firefox and chrome shows notification and works fine. But when I trying to send FCM Data Message, firefox doesn't receive and log Messages.
I am using a HTTPS secure url and also this template.
This is my javascript function:
function sendMSG()
{
var _ID = $("#user_id").val();
var ServerKey = "SERVER_KEY";
var msg = {
"to": _ID,
"data": {
"Nick": "Mario",
"body": "great match!",
"Room": "PortugalVSDenmark"
}
}
;
$.ajax({
type: 'POST',
url: "https://fcm.googleapis.com/fcm/send",
headers: {
Authorization: 'key=' + ServerKey
},
contentType: "application/json",
data: JSON.stringify(msg),
success: function (response) {
console.log(response);
},
error: function (xhr, status, error) {
console.log(xhr.error);
}
});
}
And my service worker:
importScripts('/script/firebase.js');
importScripts('/script/firebase-app.js');
importScripts('/script/firebase-messaging.js');
firebase.initializeApp({ 'messagingSenderId': 'MY_ID' });
const messaging = firebase.messaging()
messaging.setBackgroundMessageHandler(function (payload) {
console.log('FIREBASE call', payload);
if (payload.data.status == 'calling') {
channel.postMessage(payload.data)
return self.registration.showNotification('Nuevo pedido', { body: "Llamada para transporte de un pedido" })
}
})
chrome responses message in console like this:
But there is no any response from firefox.
Can anyone help me to solve this issue?

finally i found where is the problem:
the contentType must be placed in the headers brackets like this:
headers: {
'Content-Type': 'application/json',
Authorization: 'key=' + ServerKey
},
now, all functions works fine in firefox
