I'm trying to make an https request from my node server to my main php server but it looks like the request isn't going through. I'm pretty sure there is an issue with the hostname line as I have read people having random issues with it but it could be something else. The php server is secured with ssl and is an amazon ec2.
exports.authenticate = function(request, callback) {
var https = require('https');
var options = {
hostname: 'https://mysite.com',
port: 443,
path: '/ajaxim/auth.php',
method: 'GET',
cookie: exports.cookie + '=' + request.sessionID
};
var req = https.request(options)
req.end();
req.on('response', function (response) {
var data = '';
response.setEncoding('utf8');
response.on('data', function(chunk) {
data += chunk;
});
//console.log (request.sessionID);
response.on('end', function() {
try {
callback(JSON.parse(data));
} catch(e) {
callback();
}
});
});
};
Any suggestions will be insanely helpful. I'm just trying to get hint of the right direction.

I am trying to set the message to "Data Loading.." whenever the data is loading in the grid. It is working fine if I don't make an Ajax call. But, when I try to make Ajax Request, It is not showing up the message "Loading data..", when it is taking time to load the data. Can someone please try to help me with this.. Thanks in Advance.
_loadData: function(x){
var that = this;
if(this.project!=undefined) {
this.setLoading("Loading data..");
this.projectObjectID = this.project.value.split("/project/");
var that = this;
this._ajaxCall().then( function(content) {
console.log("assigned then:",content,this.pendingProjects, content.data);
that._createGrid(content);
})
}
},
_ajaxCall: function(){
var deferred = Ext.create('Deft.Deferred');
console.log("the project object ID is:",this.projectObjectID[1]);
var that = this;
console.log("User Reference:",that.userref,this.curLen);
var userObjID = that.userref.split("/user/");
Ext.Ajax.request({
url: 'https://rally1.rallydev.com/slm/webservice/v2.0/project/'+this.projectObjectID[1]+'/projectusers?fetch=true&start=1&pagesize=2000',
method: 'GET',
async: false,
headers:
{
'Content-Type': 'application/json'
},
success: function (response) {
console.log("entered the response:",response);
var jsonData = Ext.decode(response.responseText);
console.log("jsonData:",jsonData);
var blankdata = '';
var resultMessage = jsonData.QueryResult.Results;
console.log("entered the response:",resultMessage.length);
this.CurrentLength = resultMessage.length;
this.testCaseStore = Ext.create('Rally.data.custom.Store', {
data:resultMessage
});
this.pendingProjects = resultMessage.length
console.log("this testcase store:",resultMessage);
_.each(resultMessage, function (data) {
var objID = data.ObjectID;
var column1 = data.Permission;
console.log("this result message:",column1);
if(userObjID[1]==objID) {
console.log("obj id 1 is:",objID);
console.log("User Reference 2:",userObjID[1]);
if (data.Permission != 'Editor') {
deferred.resolve(this.testCaseStore);
}else{
this.testCaseStore = Ext.create('Rally.data.custom.Store', {
data:blankdata
});
deferred.resolve(this.testCaseStore);
}
}
},this)
},
failure: function (response) {
deferred.reject(response.status);
Ext.Msg.alert('Status', 'Request Failed.');
}
});
return deferred;
},
The main issue comes from your Ajax request which is using
async:false
This is blocking the javascript (unique) thread.
Consider removing it if possible. Note that there is no guarantee XMLHttpRequest synchronous requests will be supported in the future.
You'll also have to add in your success and failure callbacks:
that.setLoading(false);
In my app, I send a post request to the server with data containing a CSV file:
$.ajax({
type:"POST",
contentType: "application/json",
url:"/",
data: JSON.stringify({fileData:My_CSV_FILE}),
success: function(csvJson) {
console.log('in the done block!');
//can use csvJson in this handler
});
});
Note: I'm posting to the home route, and I am able to get a response with the data converted from the server. The problem is that whether I run on localhost or Heroku, I am only able to trigger the POST request once, then I have to restart the server (even if I refresh the page). So I know the issue is with my route somewhere:
UPDATED TO INCLUDE FULL SERVER FILE:
'use strict';
const express = require('express');
const csvtojson = require('csvtojson');
const PORT = process.env.PORT || 3000;
const bodyParser = require('body-parser');
const Converter = require('csvtojson').Converter;
var converter = new Converter({});
let app = express();
app.use(bodyParser.json({limit: '300kb'}));
app.use(express.static(__dirname +'/public'));
app.post('/',function(req,res) {
var csvFile = (req.body.fileData);
converter.fromString(csvFile, function(err, result) {
if(!err) {
console.log(result);
res.json(result);
}else {
res.json({error: 'Could not convert'});
}
})
});
app.listen(PORT, () => {
console.log(`app listening on port ${PORT}`);
});
I'm using Express 4. Again, everything works, but only once. When I run Heroku logs, or check the console on localhost I get:
Error: Can't set headers after they are sent.
But I don't understand how I'm re-setting them.
If wanting to run on localhost, here is a link to the projects github: https://github.com/qctimes/calendar_export
You should move the converter instantiation to be done inside the app.post callback method. This way it will instantiate a new object at every request.
This is is how your code should be:
'use strict';
const express = require('express');
const csvtojson = require('csvtojson');
const PORT = process.env.PORT || 3000;
const bodyParser = require('body-parser');
const Converter = require('csvtojson').Converter;
let app = express();
app.use(bodyParser.json({limit: '300kb'}));
app.use(express.static(__dirname +'/public'));
app.post('/',function(req,res) {
var csvFile = (req.body.fileData);
var converter = new Converter({}); // instantiation is done here
converter.fromString(csvFile, function(err, result) {
if(!err) {
console.log(result);
res.send(result);
}else {
res.send({error: 'Could not convert'});
}
});
});
app.listen(PORT, () => {
console.log(`app listening on port ${PORT}`);
});
How do I send data (via ajax post or get) from BeagleBone Black to a web server using BoneScript?
As I understand, XMLHttpRequest does not exist. Is there another approach?
I found the solution: In fact, I see this operation is not related to beaglebone. It relates to nodejs. So, the key is require('http') by node.
var http = require('http');
http.get('http://www.example.com', function(response) {
var response_data = '';
response.on('data', function(chunk) {
response_data += chunk;
})
.on('end', function() {
console.log(response_data);
})
.on('error', function(e) {
console.log('Error: ' + e.message);
});
});
OR if you want to do that simpler, you can use Requistify
npm install requestify
After installed you can use it like:
var requestify = require('requestify');
// GET Example
requestify.get('http://example.com').then(function(response) {
// Get the response body (JSON parsed - JSON response or jQuery object in case of XML response)
response.getBody();
// Get the response raw body
response.body;
});
// POST example
requestify.post('http://example.com', {
hello: 'world'
})
.then(function(response) {
// Get the response body
response.getBody();
});
I'm trying to write proxy server that will proxy (almost) all http/s requests. Almost all because I need catch requests for some specific https url's and as response send the file from hdd instead of real response from the web.
Whole solution should works as proxy in the browser and have to work on windows 7. I started with my own proxy based on express.js. It works great ... but unfortunately not via https. Then I was trying to use several existing node.js proxy servers from github (https://github.com/horaci/node-mitm-proxy, https://github.com/Hypermediaisobar/hyperProxy and few other) but any of them worked in windows environment on https (or I don't know how to congiure them).
Finally I found somewhere in internet code (don't have the link to source) which works via https (see code below). The problems with this code is, that I can't find right way to check the incoming request url and depending on the request url handle them in different ways.
I will be grateful if someone could help me with that.

are you asking for
http://expressjs.com/4x/api.html#req.secure
req.secure -> https
http://expressjs.com/4x/api.html#req.protocol
req.protocol -> http
http://expressjs.com/4x/api.html#req.host
req.host
req.url
this should all be on your userRequest
I probably did not understand your question correctly.
Just add this line:
var https = require('https');
And when you are making regular http requests, use http.request, and for the ssl requests, https.request.
My node app posts an object (consisting of data collected in a form on the client) to Salesforce via their API. On receiving a success or error message, I would like to send it to the client-side, then display it. Socket.io seemed like the tool for this in my simple node/express3 app, but beyond the simple demo I'm not able to get data to pass between my server and my client.
My relevant server side code:
var express = require('express');
var port = 5432;
var app = module.exports = express();
var server = require('http').createServer(app);
var nforce = require('nforce');
var org = nforce.createConnection({
clientId: 'MY_CLIENT_ID',
clientSecret: 'MY_CLIENT_SECRET',
redirectUri: 'http://localhost:5432/oauth/_callback'
});
var io = require('socket.io').listen(server);
// here I authenticate with Salesforce, this works fine
app.post('/salesforce', function(req, res){
var lead = nforce.createSObject('Lead');
// here I construct the lead object, which also works fine
org.insert(lead, oauth, function(err, res) {
if (err === null) {
console.log(res);
leadSuccessMessage(res);
}
else {
console.log(err);
var error = {
errorCode: err.errorCode,
statusCode: err.statusCode,
messageBody: err.messageBody
};
console.log(error);
leadErrorMessage(error);
}
});
}
function leadSuccessMessage(res) {
var resp = res;
console.log('called success message from server');
io.sockets.on('connection', function (socket) {
socket.emit('sfRes', resp);
socket.on('thanks', function (data) {
console.log(data);
});
});
}
function leadErrorMessage(error) {
var err = error;
console.log('called error message from server');
io.sockets.on('connection', function (socket) {
console.log("socket is: " + socket);
socket.emit('sfRes', err);
socket.on('thanks', function (data) {
console.log(data);
});
});
}
And my relevant client side scripts:
<script src="/socket.io/socket.io.js"></script>
<script>
current.page = document.URL;
console.log("current page is: " + current.page);
var socket = io.connect(current.page);
socket.on('sfRes', function (data) {
console.log("client received: " + data);
fst.showLeadStatus(data);
socket.emit('thanks', {message: "received server feedback"});
});
</script>
When I post the form containing valid data using a spicy little AJAX call:
postToSF: function(){
$('#submitLead').on('click', function(e){
e.preventDefault();
var formData = $('#lead_form').serialize();
$.ajax({
type: 'POST',
url: '/salesforce',
data: formData,
success: function(){
fst.log('success!');
},
error: function(xhr, ajaxOptions, thrownError){
console.error(xhr.status); // 0
console.error(thrownError);
}
});
});
}
All I get are tears, and these in the server-side console:
// the result of `console.log(res)`
{ id: '00Qa000001FZfhKEAT', success: true, errors: [] }
// and proof that `leadSuccessMessage()` got called
called success message from server
Instead of calling this function from a client-side object as it's supposed to:
showLeadStatus: function(response){
if (response.success) {
fst.log("showing lead status as: " + response);
$('#leadStatus').addClass('success').removeClass('error').fadeIn().delay(4000).fadeOut();
}
else {
fst.log("showing lead status as: " + response);
$('#leadStatus').text(response.messageBody).addClass('error').removeClass('success').fadeIn().delay('4000').fadeOut();
}
$('#startOver').click();
}
Which works fine if I call it in the console passing it the data the server is supposed to be socketing over:
// this works, gosh darn it
fst.showLeadStatus({ id: '00Qa000001FZfhKEAT', success: true, errors: [] });
The Salesforce post error case doesn't surface anything to the client either. And there are no errors in the client or server console to contend with.
I'm stumped. Please help!
I would do something like this -
var mysocket = null;
var io = require('socket.io').listen(server);
io.sockets.on('connection', function (socket) {
mysocket = socket;
socket.on('thanks', function (data) {
console.log(data);
});
});
app.post('/salesforce', function(req, res){
....
....
})
function leadSuccessMessage(res) {
var resp = res;
console.log('called success message from server');
if(mysocket)
mysocket.emit('sfRes', resp);
}
function leadErrorMessage(error) {
var err = error;
console.log('called error message from server');
if(mysocket)
mysocket.emit('sfRes', err);
}
