Connect to rest API with Meteor - rest

I want to connect to rest API with auth in Meteor but when I run through their docs cant see anything stuff for connecting to rest API. All I can see it that the HTTP request. So, I tried using it. I need to connect to this:
URL: http://lpgp-dev.mrkt.it/test/oauth/rest/testview2
key: 'mykey'
secret: 'my secret'
For now I have this lines of code:
from server:
Meteor.methods({
getArticles: function () {
check(q, String);
this.unblock();
try {
var result = HTTP.call("GET", "http://lpgp-dev.mrkt.it/test/oauth/rest/testview2",
{params: {key: 's86MopNFA6pwmBXQoEw8k5yBVAVjN8vz', secret: 'cKC2tpXP3ZRQvqAsobCPeK2jB4kjsDos'}});
return result;
} catch (e) {
// Got a network error, time-out or HTTP error in the 400 or 500 range.
return false;
}
}
});
from client which I called the method:
var getResponse = function(){
Meteor.call('getArticles', function (error, result) {
if (!error) {
var res = JSON.parse(result.content);
/*var _res = _(res.response.docs).toArray();*/
/*Session.set('numCount', res.response.numFound);
Session.set('news', _res);*/
console.log(res);
}else{
console.log(error);
}
});
}
When I run it return this error:
errorClass: Internal server error [500] of undefined
hope you can help me. Thanks...

MongoDB GET request returning empty array

I am using nextjs and mongodb. I performed a GET request but Mongodb returned an empty array. The POST request before that has no problem. Both POST and GET request have status 200 tho.
if (req.method === 'GET') {
try {
const getData = await db.collection(peopleData).find({}).toArray(); // peopleData is from query
res.json(getData);
res.status(200).json({ message: getData });
} catch (error) {
return res.status(500).json({ message: error });
}
}
Thanks in advance

AWS Lambda - MongoDB resource optimization

I'm building facebook chatbot using AWS Lambda and MongoDB. At the moment, my application is pretty simple but I'm trying to nail down the basics before I move onto the complex stuff.
I understand AWS Lambda is stateless but I've read adding below line in handler along with variables initialized outside handler, I don't have to establish DB connection on every request.
context.callbackWaitsForEmptyEventLoop = false;
(I've read this from this article; https://www.mongodb.com/blog/post/optimizing-aws-lambda-performance-with-mongodb-atlas-and-nodejs)
I'm adding my entire code below
'use strict'
const
axios = require('axios'),
mongo = require('mongodb'),
MongoClient = mongo.MongoClient,
assert = require('assert');
var VERIFY_TOKEN = process.env.VERIFY_TOKEN;
var PAGE_ACCESS_TOKEN = process.env.PAGE_ACCESS_TOKEN;
var MONGO_DB_URI = process.env.MONGO_DB_URI;
let cachedDb = null;
let test = null;
exports.handler = (event, context, callback) => {
var method = event.context["http-method"];
context.callbackWaitsForEmptyEventLoop = false;
console.log("test :: " + test);
if (!test) {
test = "1";
}
// process GET request --> verify facebook webhook
if (method === "GET") {
var queryParams = event.params.querystring;
var rVerifyToken = queryParams['hub.verify_token']
if (rVerifyToken === VERIFY_TOKEN) {
var challenge = queryParams['hub.challenge'];
callback(null, parseInt(challenge))
} else {
var response = {
'body': 'Error, wrong validation token',
'statusCode': 403
};
callback(null, response);
}
// process POST request --> handle message
} else if (method === "POST") {
let body = event['body-json'];
body.entry.map((entry) => {
entry.messaging.map((event) => {
if (event.message) {
if (!event.message.is_echo && event.message.text) {
console.log("BODY\n" + JSON.stringify(body));
console.log("<<MESSAGE EVENT>>");
// retrieve message
let response = {
"text": "This is from webhook response for \'" + event.message.text + "\'"
}
// facebook call
callSendAPI(event.sender.id, response);
// store in DB
console.time("dbsave");
storeInMongoDB(event, callback);
}
} else if (event.postback) {
console.log("<<POSTBACK EVENT>>");
} else {
console.log("UNHANDLED EVENT; " + JSON.stringify(event));
}
})
})
}
}
function callSendAPI(senderPsid, response) {
console.log("call to FB");
let payload = {
recipient: {
id: senderPsid
},
message: response
};
let url = `https://graph.facebook.com/v2.6/me/messages?access_token=${PAGE_ACCESS_TOKEN}`;
axios.post(url, payload)
.then((response) => {
console.log("response ::: " + response);
}).catch(function(error) {
console.log(error);
});
}
function storeInMongoDB(messageEnvelope, callback) {
console.log("cachedDB :: " + cachedDb);
if (cachedDb && cachedDb.serverConfig.isConnected()) {
sendToAtlas(cachedDb.db("test"), messageEnvelope, callback);
} else {
console.log(`=> connecting to database ${MONGO_DB_URI}`);
MongoClient.connect(MONGO_DB_URI, function(err, db) {
assert.equal(null, err);
cachedDb = db;
sendToAtlas(db.db("test"), messageEnvelope, callback);
});
}
}
function sendToAtlas(db, message, callback) {
console.log("send to Mongo");
db.collection("chat_records").insertOne({
facebook: {
messageEnvelope: message
}
}, function(err, result) {
if (err != null) {
console.error("an error occurred in sendToAtlas", err);
callback(null, JSON.stringify(err));
} else {
console.timeEnd("dbsave");
var message = `Inserted a message into Atlas with id: ${result.insertedId}`;
console.log(message);
callback(null, message);
}
});
}
I did everything as instructed and referenced a few more similar cases but somehow on every request, "cachedDb" value is not saved from previous request and the app is establishing the connection all over again.
Then I also read that there is no guarantee the Lambda function is using the same container on multiple requests so I made another global variable "test". "test" variable value is logged "1" from the second request which means it's using the same container but again, "cachedDb" value is not saved.
What am I missing here?
Thanks in advance!
In short AWS Lambda function is not a permanently running service of any kind.
So, far I know AWS Lambda works on idea - "one container processes one request at a time".
It means when request comes and there is available running container for the Lambda function AWS uses it, else it starts new container.
If second request comes when first container executes Lambda function for first request AWS starts new container.
and so on...
Then there is no guarantee in what container (already running or new one) Lambda function will be executed, so... new container opens new DB connection.
Of course, there is an inactivity period and no running containers will be there after that. All will start over again by next request.

How to use the login credentials with php in ionic project

I want to authenticate the user_name and password field. the user_name and password field is stored in database with php. how to get the data from the server in ionic project.
Thanks in advance.
You can create a service script that can send post data to PHP and receive a JSON response.
Post data should be sent as an object containing element name and values in the following format:
var myObj = {username: 'username', password:'password'};
Below is a service example:
yourApp.service('YourService', function ($q, $http) {
return {
login: function (data) {
var deferred = $q.defer(),
promise = deferred.promise;
$http({
url: 'http://www.example.com/yourPHPScript.php',
method: "POST",
data: data,
headers: {'Content-Type': 'application/json'}
})
.then(function (response) {
if (response.data.error.code === "000") {
deferred.resolve(response.data.appointments);
} else {
deferred.reject(response.data);
}
}, function (error) {
deferred.reject(error);
});
promise.success = function (fn) {
promise.then(fn);
return promise;
};
promise.error = function (fn) {
promise.then(null, fn);
return promise;
};
return promise;
}
};
});
From your login controller you call the following code to use the service (make sure you add the name of the service to your controller declaration)
YourService.login(loginData)
.then(function (data) {
// on success do sthg
}, function (data) {
//log in failed
// show error msg
});

How to catch a 401 (or other status error) in an angular service call?

Using $http I can catch errors like 401 easily:
$http({method: 'GET', url: 'http://localhost/Blog/posts/index.json'}).
success(function(data, status, headers, config) {
$scope.posts = data;
}).
error(function(data, status, headers, config) {
if(status == 401)
{
alert('not auth.');
}
$scope.posts = {};
});
But how can I do something similar when using services instead. This is how my current service looks:
myModule.factory('Post', function($resource){
return $resource('http://localhost/Blog/posts/index.json', {}, {
index: {method:'GET', params:{}, isArray:true}
});
});
(Yes, I'm just learning angular).
SOLUTION (thanks to Nitish Kumar and all the contributors)
In the Post controller I was calling the service like this:
function PhoneListCtrl($scope, Post) {
$scope.posts = Post.query();
}
//PhoneListCtrl.$inject = ['$scope', 'Post'];
As suggested by the selected answer, now I'm calling it like this and it works:
function PhoneListCtrl($scope, Post) {
Post.query({},
//When it works
function(data){
$scope.posts = data;
},
//When it fails
function(error){
alert(error.status);
});
}
//PhoneListCtrl.$inject = ['$scope', 'Post'];
in controller call Post like .
Post.index({},
function success(data) {
$scope.posts = data;
},
function err(error) {
if(error.status == 401)
{
alert('not auth.');
}
$scope.posts = {};
}
);
Resources return promises just like http. Simply hook into the error resolution:
Post.get(...).then(function(){
//successful things happen here
}, function(){
//errorful things happen here
});
AngularJS Failed Resource GET
$http is a service just like $resource is a service.
myModule.factory('Post', function($resource){
return $http({method: 'GET', url: 'http://localhost/Blog/posts/index.json'});
});
This will return the promise. You can also use a promise inside your factory and chain that so your factory (service) does all of the error handling for you.
