I tried to integrate node js with my application, I have just test the http server It works well, but when I use https server as following with my index.php to subscribe the message, This does not work.
Start a server
var https = require('https'),
faye = require('faye');
var fs = require('fs');
var options = {
key: fs.readFileSync('/etc/apache2/ssl/apache.key'),
cert: fs.readFileSync('/etc/apache2/ssl/apache.crt')
};
var server = https.createServer(options),
bayeux = new faye.NodeAdapter({mount: '/'});
bayeux.attach(server);
server.listen(1337);
Create a client
<script src="faye-browser-min.js"></script>
<script>
var client = new Faye.Client('https://localhost:1337/');
client.subscribe('/messages/*', function(message) {
alert('Got a message:');
});
</script>
Send messages
I used Faye client to push message in test.php .
$adapter = new \Nc\FayeClient\Adapter\CurlAdapter();
$client = new \Nc\FayeClient\Client($adapter, 'https://localhost:1337/');
$client->send("/messages/test", array("name" => "foo"), array("token" => "456454sdqd"));
Thank you,
Please tell me how to check is there any error on server side.
I fixed issue my self, The issue was not in server side. It was in php Faye Client side. That Php Client works fine for HTTP server, but I need to use it for HTTPS server. I have done following changes then It works fine.
/vendor/nc/faye-client/src/Nc/FayeClient/Adapter/CurlAdapter.php
public function postJSON($url, $body)
{
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_POSTFIELDS, $body);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($body),
));
curl_exec($curl);
curl_close($curl);

I want send post request from php to python and get answer
I write this script which the send post
$url = 'http://localhost:8080/cgi-bin/file.py';
$body = 'hello world';
$options = array('method'=>'POST',
'content'=>$body,
'header'=>'Content-type:application/x-ww-form-urlencoded');
$context = stream_context_create(array('http' => $options));
print file_get_contents($url, false,$context);
I'm use custom python server
from http.server import HTTPServer, CGIHTTPRequestHandler
server_address = ("", 8080)
httpd = HTTPServer(server_address, CGIHTTPRequestHandler)
httpd.serve_forever()
And python script which the takes post request
print('Content-type: text/html\n')
import cgi
form = cgi.FieldStorage()
text2 = form.getfirst("content", "empty")
print("<p>TEXT_2: {}</p>".format(text2))
And then I get
write() argument must be str, not bytes\r\n'
How can it be solved?
P.S Sorry for my bad english
Check curl extension for php http://php.net/manual/en/book.curl.php
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://localhost:8080/cgi-bin/file.py");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"postvar1=value1&postvar2=value2&postvar3=value3");
// in real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS,
// http_build_query(array('postvar1' => 'value1')));
// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec ($ch);
curl_close ($ch);
You can also use a library like guzzle that may have some other bells and whistles you may want to use.
Example usage can be found on this other answer here:

I tried to make a request to my nodeJS using CURL from PHP.
Here is my code:
$host = 'http://my_ip:8080/ping';
$json = '{"id":"13"}';
$ch = curl_init($host);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($json))
);
$data = curl_exec($ch);
var_dump($data);
But it doesn't work. I received bool(FALSE) in data var.
NodeJS:
app.use(router(app));
app.post('/ping', bodyParser, ping);
port = 8080;
app.listen(port, webStatus(+port));
function* ping() {
console.log(this.request.body);
this.body = 1;
}
I tried with NodeJS Http-post and it works:
http.post = require('http-post');
http.post('http://my_ip:8080/ping', { id: '13' }, function (res) {
res.on('data', function (chunk) {
console.log(chunk);
});
});
Is it something wrong with PHP code?
PS: The CURL is included in PHP.
Your ping function is not well implemented I think.
Also, you need to call the send method in order to send the HTTP response.
You should declare the function like this :
app.use(bodyParser); // You can use a middleware like this too.
app.post('/ping', ping);
function ping (req, res) {
console.log(req.body); // Since you use `bodyParser` middleware, you can get the `body` directly.
// Do your stuff here.
res.status(200).send('toto');
}
I have a Flask app, with a basic function, where I have exposed app.run() to a public ip, so that it is accessible from an external server;[ using Flask - Externally Visible Dev Server ]
#app.route('/')
def hello_world():
return 'Hello World!'
if __name__ == '__main__':
app.run(host = '0.0.0.0', port = 8080)
The curl request I have written in my php code is:
$signed_url = "http://my-ip-address:8080/";
$ch = curl_init($signed_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data= curl_exec($ch);
echo $data;
I can do a curl request :
curl http://my-ip-address:8080/
from command line. However, when the curl request is embedded within my PHP code, it gives me an error "Connection refused".
Kindly help!
If the PHP code is on another server, but your command line cURL request is on the same server, then you aren't comparing apples to apples.
Two things that might be wrong:
Your Flask server has a firewall that doesn't allow external connections.
You are connecting using an private network IP address rather than a public IP address.
For now your PHP code looks correct, so I would narrow down the problem a little bit. Ignore that PHP code and try to connect using cURL on the command line from the same server you are running your PHP code on.
try to set your port with curl options like this:
curl_setopt($ch, CURLOPT_PORT, 8080);
so your signed url will be:
$signed_url = "http://my-ip-address";
I use this code for my work and worked :)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://localhost:5000/spmi/api/1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\"teks_analysis\":\"tidak ada skor nol\"}");
curl_setopt($ch, CURLOPT_POST, 1);
$headers = array();
$headers[] = 'Content-Type: application/json';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$result = curl_exec($ch);
if (curl_errno($ch)) {
echo 'Error:' . curl_error($ch);
}
curl_close($ch);
the key is CURLOPT_POSTFIELDS
Im trying to send a GET or POST request from PHP (CLI), to a Node.js/Sockets.IO application, using only basic cURL. This is what i have so far, i can see the response coming in to node.js (from the cli), but can not get any farther. Currently i only want the parameters sent to the console. (I can expand on that later)
Any help would be great!
(FYI: I did look at this, Socket.io from php source, but need more help. Exact code would be great)
PHP
$qry_str = "?msg_from_php=This_is_a_test123&y=20";
$ServerAddress = 'http://10.1.1.69/socket.io/1/websocket/TICWI50sbew59XRE-O';
$ServerPort = '4000';
$TimeOut = 20;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $ServerAddress. $qry_str);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
curl_setopt($ch, CURLOPT_PORT, $ServerPort);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $TimeOut);
curl_setopt($ch, CURLOPT_TIMEOUT, '3');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);
// not sure if it should be in an array
//$data = array('msg_from_php' => 'simple message!');
//curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$content = trim(curl_exec($ch));
curl_close($ch);
echo " Sent! Content: $content \r\n";
Node.JS
var express = require('express'), http = require('http');
var app = express();
var server = http.createServer(app);
var io = require('socket.io').listen(server);
io.configure('production', function(){
io.enable('browser client minification');
io.enable('browser client etag');
io.enable('browser client gzip');
io.set('log level', 1);
io.set('transports', ['websocket', 'flashsocket', 'htmlfile', 'xhr-polling', 'jsonp-polling']);
io.set("polling duration", 30);
});
server.listen(4000); // 80,443, 843, 4000, 4001
io.sockets.on('connection', function (socket) {
socket.on('msg_from_php, function (data) {
console.log(data);
});
});
You're trying to make an ordinary HTTP connection to a socket.io server, but socket.io doesn't speak plain HTTP; it uses at the very least a specialized handshaking protocol, and if it uses websocket transport it won't be using HTTP at all. AFAIK there's no PHP implementation of a socket.io client.
Fortunately, it looks like your PHP application needs to send to your node application on its own terms, not the other way around, so all you need to do is use express to define a couple routes to implement a RESTful interface; your PHP app can then use cURL to POST to the URL corresponding to the appropriate route.
I am trying to send a post request through PHP cURL to my node.js server to then emit a message to the client. The server is working and setup as follows:
var app = require('http').createServer(handler)
, io = require('socket.io').listen(app)
, fs = require('fs')
, qs = require('querystring')
app.listen(8000);
function handler(req, res) {
// set up some routes
switch(req.url) {
case '/push':
if (req.method == 'POST') {
console.log("[200] " + req.method + " to " + req.url);
var fullBody = '';
req.on('data', function(chunk) {
fullBody += chunk.toString();
if (fullBody.length > 1e6) {
// FLOOD ATTACK OR FAULTY CLIENT, NUKE REQUEST
req.connection.destroy();
}
});
req.on('end', function() {
// Send the notification!
var json = qs.stringify(fullBody);
console.log(json.message);
io.sockets.emit('push', { message: json.message });
// empty 200 OK response for now
res.writeHead(200, "OK", {'Content-Type': 'text/html'});
res.end();
});
}
break;
default:
// Null
};
}
and my PHP is as follows:
$curl = curl_init();
$data = array('message' => 'simple message!');
curl_setopt($curl, CURLOPT_URL, "http://localhost:8000/push");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_exec($curl);
The console says that json.message is undefined. Why is it undefined?
You're using querystring.stringify() incorrectly. See the documentation on querystring's methods here:
http://nodejs.org/docs/v0.4.12/api/querystring.html
I believe what you want is something like JSON.stringify() or querystring.parse(), as opposed to querystring.stringify() which is supposed to serialize an existing object into a query string; which is the opposite of what you are trying to do.
What you want is something that will convert your fullBody string into a JSON object.
If your body simply contains a stringified version of the JSON blob, then replace
var json = qs.stringify(fullBody);
With
var json = JSON.parse(fullBody);
try this code
<?php
$data = array(
'username' => 'tecadmin',
'password' => '012345678'
);
$payload = json_encode($data);
// Prepare new cURL resource
$ch = curl_init('https://api.example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
// Set HTTP Header for POST request
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($payload))
);
// Submit the POST request
$result = curl_exec($ch);
// Close cURL session handle
curl_close($ch);
