I have a very simple request, but warn me Parse Error:
var http = require('http');
var url = require('url');
var opts = {
host: 'www.appletreebooks.com',
path: 'www.appletreebooks.com/appIndex.php?c=eshop&m=get_hot_new_book_list&per_page=1&devid=c4c8874d16d84cde8fc7b9037ad8e26465bd1560&uid=1&ln=sn',
}
var req = http.request(opts, function (res) {
res.setEncoding('utf8');
var data = ""
res.on('data', function(d) {
data += d;
})
res.on('end', function() {
console.log(data);
})
})
req.on('error', function(e) {
console.log('problem with request: ' + e.message);
});
req.end();
But the response me Parse Error
What's wrong with my code? How can I get the data correctly?
Your opts.path should not include the hostname.
var opts = {
host: 'www.appletreebooks.com',
path: '/appIndex.php?c=eshop&m=get_hot_new_book_list&per_page=1&devid=c4c8874d16d84cde8fc7b9037ad8e26465bd1560&uid=1&ln=sn',

Hi I am trying to do a http POST request to send some blob data. But I also need to send some string values with it for authentication (jwt).
let options = {uname: user.uname, authKey: user.authKey, video: qde.debrief.blob}
let xhr = await xhrRequest(`${serverIp}/api/file`, "POST", options, 'none');
prom.push(xhr);
And the xhrRequest method is
//xhr function with url input and isValid and data output
function xhrRequest(url, type, body, header) {
return new Promise((resolve, reject) => {
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
if (xhr.readyState === 4 && xhr.status === 200) {
resolve({ error: false, body: JSON.parse(xhr.response) });
} else if (xhr.readyState === 4 && xhr.status !== 200) {
resolve({ error: true, body: JSON.parse(xhr.response) });
}
}
xhr.timeout = 5000;
xhr.ontimeout = () => {
resolve({ error: true, body: "Error Connecting to server" });
}
xhr.onerror = function () {
resolve({ error: true, body: "Error Connecting to server" });
}
xhr.open(type, url, true);
if (type == "POST") {
if(!header){
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
}
xhr.send(body)
} else {
xhr.send();
}
})
}
I am currently building a microservice that is responsible to communicate with Microsoft Graph, I have already made one with Loopback 3 and this was not a problem.
Except now, I am trying to do the same thing but with Loopback 4, but since the language changes from JavaScript to TypeScript I don't know if it's still possible to achieve this.
This was the code I used for Loopback 3 in my root server file:
'use strict';
const express = require('express');
const erouter = require('express').Router();
var session = require('express-session');
var passport = require('passport');
var OIDCStrategy = require('passport-azure-ad').OIDCStrategy;
const request = require('request');
var querystring = require('querystring');
const graph = require('./graph.service');
const getBookings = require('./getBookings.service');
const cors = require('cors');
var compression = require('compression');
module.exports = function(server) {
// Install a `/` route that returns server status
var router = server.loopback.Router();
router.get('/', server.loopback.status());
// Configure simple-oauth2
const oauth2 = require('simple-oauth2').create({
client: {
id: process.env.OAUTH_APP_ID,
secret: process.env.OAUTH_APP_PASSWORD
},
auth: {
tokenHost: process.env.OAUTH_AUTHORITY,
authorizePath: process.env.OAUTH_AUTHORIZE_ENDPOINT,
tokenPath: process.env.OAUTH_TOKEN_ENDPOINT
}
});
passport.serializeUser(function(user, done) {
var MSUser = server.models.MSUser;
var id = user.profile.oid;
MSUser.find({ where: { oid: id } }, function(err, msu) {
if (err) return done(err, null);
if (!msu) {
MSUser.create(user);
} else {
done(null, id);
}
});
});
passport.deserializeUser(function(id, done) {
var MSUser = server.models.MSUser;
MSUser.findById(id, function(err, user) {
if (err) return next(err);
done(null, user);
});
});
async function signInComplete(iss, sub, profile, accessToken, refreshToken, params, done) {
if (!profile.oid) {
return done(new Error("No OID found in user profile."), null);
}
try {
const user = await graph.getUserDetails(accessToken);
if (user) {
profile['email'] = user.mail ? user.mail.toLowerCase() : user.userPrincipalName.toLowerCase();
}
} catch (err) {
done(err, null);
}
let oauthToken = oauth2.accessToken.create(params);
var AuthUser = server.models.AuthUser;
var user = {};
AuthUser.find({ where: { email: profile['email'] } }, function(err, au) {
if (err) return done(err, null);
if (au.length != 1) return done(new Error("User was not found with that email address."), null);
user = au[0];
const dataMsAuth = querystring.stringify({
"created": new Date().toDateString(),
"token_type": oauthToken.token.token_type,
"expires_in": oauthToken.token.expires_in,
"access_token": oauthToken.token.access_token,

"id_token": oauthToken.token.id_token,
"expires_at": new Date(oauthToken.token.expires_at).toDateString()
});
const postMSAuth = {
url: process.env.API_URL + "api/Companies/" + user.companyId + "/msauth",
method: 'POST',
body: dataMsAuth,
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}
request(postMSAuth, function(err, resp, body) {
if (err) return done(err, null);
var MSUser = server.models.MSUser;
var id = profile.oid;
var msuser = { profile, oauthToken, oid: id, email: profile.email }
MSUser.findById(id, function(err, msu) {
if (err) return done(err, null);
if (!msu) {
MSUser.create(msuser);
}
});
return done(null, msuser);
});
});
}
passport.use(new OIDCStrategy({
identityMetadata: `${process.env.OAUTH_AUTHORITY}${process.env.OAUTH_ID_METADATA}`,
clientID: process.env.OAUTH_APP_ID,
responseType: 'code id_token',
responseMode: 'form_post',
redirectUrl: process.env.OAUTH_REDIRECT_URI,
allowHttpForRedirectUrl: true,
clientSecret: process.env.OAUTH_APP_PASSWORD,
validateIssuer: false,
passReqToCallback: false,
scope: process.env.OAUTH_SCOPES.split(' ')
},
signInComplete
));
var app = express();
app.use(compression());
app.use(session({
secret: process.env.BOOKINGS_LOOPBACK_SECRET,
resave: false,
saveUninitialized: false,
unset: 'destroy'
}));
app.use("/result", express.static('client'));
app.use(passport.initialize());
app.use(passport.session());
app.use(cors({
origin: '*'
}));
erouter.get('/API/bookings/:companyid', getBookings());
erouter.get('/auth/signin',
function(req, res, next) {
passport.authenticate('azuread-openidconnect', {
response: res,
prompt: 'login',
state: req.query.state,
failureRedirect: process.env.WEBSITE_URL + 'settings?error=incorrect_request',
successRedirect: process.env.WEBSITE_URL + 'settings?auth=success'
})(req, res, next);
}
);
erouter.post('/auth/callback',
function(req, res, next) {
passport.authenticate('azuread-openidconnect', {
response: res,
failureRedirect: process.env.WEBSITE_URL + 'settings?error=permission_denied',
successRedirect: process.env.WEBSITE_URL + 'settings?auth=success'
})(req, res, next);
}
);
app.use(erouter);
server.use(app);
server.use(router);
};
So my question is: "Is it possible to implement Microsoft Graph API in TypeScript using Loopback 4 or should I keep using Loopback 3 In JavaScript?"
Thanks in advance,

I am trying to integrate a POST API call from a lambda function using Node.js 12.x.
I tried like below:
var posturl = "My post api path";
var jsonData = "{'password':'abcdef','domain':'www.mydomain.com','username':'abc.def'}";
var req = require('request');
const params = {
url: posturl,
headers: { 'jsonData': jsonData }
};
req.post(params, function(err, res, body) {
if(err){
console.log('------error------', err);
} else{
console.log('------success--------', body);
}
});
But when I am execute it using state machine, I am getting the below exception:
{
"errorType": "Error",
"errorMessage": "Cannot find module 'request'\nRequire stack:\n- /var/task/index.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js",
"trace": [
"Error: Cannot find module 'request'",
"Require stack:",
"- /var/task/index.js",
"- /var/runtime/UserFunction.js",
"- /var/runtime/index.js",
" at Function.Module._resolveFilename (internal/modules/cjs/loader.js:815:15)",
" at Function.Module._load (internal/modules/cjs/loader.js:667:27)",

" at Runtime.exports.handler (/var/task/index.js:8:14)",
" at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"
]
}
Here the posturl is my api path and jsondata is my key value pair data.
So How can I call a POST API from lambda function? How can I pass the entire jsondata key when call API? How can I parse the response after the service call?
Update: I have tried like below
All my details are passing with a key jsonData, where I can specify that? Without that key, it will not work.
exports.handler = (event, context, callback) => {
const http = require('http');
const data = JSON.stringify({
password: 'mypassword',
domain: 'www.mydomain.com',
username: 'myusername'
});
const options = {
hostname: 'http://abc.mydomain.com',
path: 'remaining path with ticket',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Content-Length': data.length
}
};
const req = http.request(options, (res) => {
let data = '';
console.log('Status Code:', res.statusCode);
res.on('data', (chunk) => {
data += chunk;
});
res.on('end', () => {
console.log('Body: ', JSON.parse(data));
});
}).on("error", (err) => {
console.log("Error: ", err.message);
});
req.write(data);
req.end();
};

I have been trying to implement Paypal's IPN using AWS Api Gateway to get an IPN handler url. the api is integrated with a Lambda function as the "receiver".
I have tested the api gateway url using Paypal's IPN simulator.It works for the first step and I get this message "IPN was sent and the handshake was verified".
My problem is now with the next step,where I have to send the recived message back to Paypal using HTTPS post. I have tried a number of times and keep getting this error:
{
"code": "ECONNREFUSED",
"errno": "ECONNREFUSED",
"syscall": "connect",
"address": "127.0.0.1",
"port": 443
}
I really would appreciate some help in getting this to work.
I'm using node.js 8.10.Here's my Lambda function:
exports.handler = (event, context, callback) => {
console.log('Received event:', JSON.stringify(event, null, 2));
// Return 200 to caller
console.log('sending 200 back to paypal');
callback(null, {
statusCode: '200'
});
// Read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
console.log('modifying return body...');
var body = 'cmd=_notify-validate&' + event.body;
callHttps(body, context);};
function callHttps(body, context) {
console.log('in callHttp()....');
var https = require('https');
var options = {
url: 'https://ipnpb.sandbox.paypal.com/cgi-bin/webscr',
method: 'POST',
headers: {
"user-agent": "Nodejs-IPN-VerificationScript"
},
body: body
};
const req = https.request(options, (res) => {
res.on('data', (chunk) => {
// code to execute
console.log("on data - can execute code here....");
});
res.on('end', () => {
// code to execute
console.log("on end - can execute code here....");
});
});
req.on('error', (e) => {
console.log("Error has occured: ", JSON.stringify(e, null, 2));
});
req.end();}
managed to sort it out.i was using url instead of breaking it down to host and path.here's the full code that worked for me:
exports.handler = (event, context, callback) => {
console.log('Received event:', JSON.stringify(event, null, 2));
// Return 200 to caller
console.log('sending 200 back to paypal');
callback(null, {
statusCode: '200'
});
callHttps(event.body, context);};
function callHttps(body, context) {
console.log('in callHttp()....');
// Read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
console.log('modifying return body...');
var bodyModified = 'cmd=_notify-validate&' + body;
var https = require('https');
var options = {
host: "ipnpb.sandbox.paypal.com",
path: "/cgi-bin/webscr",
method: 'POST',
headers: {
'user-agent': 'Nodejs-IPN-VerificationScript',
'Content-Length': bodyModified.length,
}
};
const req = https.request(options, (res) => {
console.log('statusCode:', res.statusCode);
console.log('headers:', res.headers);
var result = '';
res.on('data', (d) => {
// get the result here
result += d;
});
res.on('end', (end) => {
// check the result
if (result === 'VERIFIED') {
// process the message
// split the message
var res = body.split("&");
// create an object
var paypalMessageObject = new Object();
// loop through split array
res.forEach(element => {
// split element
var temp = (element.toString()).split("=");
// add to the object
paypalMessageObject[temp[0]] = temp[1];
});
console.log('paypalMessageObject: ' + JSON.stringify(paypalMessageObject, null, 2));
var checkItems = {
payment_status: paypalMessageObject.payment_status,
mc_gross: paypalMessageObject.mc_gross,
mc_currency: paypalMessageObject.mc_currency,
txn_id: paypalMessageObject.txn_id,
receiver_email: paypalMessageObject.receiver_email,
item_number: paypalMessageObject.item_number,
item_name: paypalMessageObject.item_name
};
console.log('checkItems: ', JSON.stringify(checkItems, null, 2));
}
else { console.log('not verified, now what?'); }
});
});
req.on('error', (e) => {
console.log("Error has occured: ", JSON.stringify(e, null, 2));
});
req.write(bodyModified);
req.end();}
I am calling a Twilio Studio Flow Rest API from a Twilio function.
Following is the function code:
exports.handler = function(context, event, callback) {
const request = require('request');
to = event.to;
to = to.replace(/[()-.]/g, '');
to = to.replace(/ /g, '');
var postoptions = {
headers: {'AC' : 'b1xx'},
url: 'https://studio.twilio.com/v1/Flows/FWxxx8/Executions',
method: 'POST',
data: { 'from': '+1814xxx',
'to': to
}
};
request(postoptions, function(error, response, body){
callback(null, response);
});
};
The function keeps saying the Account SID adn auth token are incorrect. However sid and token are correct.
What I am missing?
You'll need to "base64" encode the Account SID and auth token when you pass them in headers.
Try something like this:
exports.handler = function (context, event, callback) {
const request = require('request');
to = event.to;
to = to.replace(/[()-.]/g, '');
to = to.replace(/ /g, '');
var username = "AC";
var password = "b1xx";
var auth = "Basic " + new Buffer(username + ":" + password).toString("base64");
var postoptions = {
headers: { 'Authorization': auth },
url: 'https://studio.twilio.com/v1/Flows/FWxxx8/Executions',
method: 'POST',
data: {
'from': '+1814xxx',
'to': to
}
};
request(postoptions, function (error, response, body) {
callback(null, response);
});
};
