POST to PHP from Node.js

Solution
Since you are sending the data with `Content-Type: application/json` you would need to read the raw input as php does not know how to read json into their globals like _GET and _POST unless you have some php extension that does it.
You can use the querystring library to parse a object into a name-value pair query string that you could than transmit with `Content-Type:application/x-www-form-urlencoded` so that the data will be parsed into the globals
var data = {
var1:"something",
var2:"something else"
};
var querystring = require("querystring");
var qs = querystring.stringify(data);
var qslength = qs.length;
var options = {
hostname: "example.com",
port: 80,
path: "some.php",
method: 'POST',
headers:{
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': qslength
}
};
var buffer = "";
var req = http.request(options, function(res) {
res.on('data', function (chunk) {
buffer+=chunk;
});
res.on('end', function() {
console.log(buffer);
});
});
req.write(qs);
req.end();
Problem
I am trying to POST some data from a Node.js application to a PHP script. For the time being I am just building a proof of concept but I am unable to get the actual data over to the PHP side. The request goes through and I get 200 back but PHP thinks the $_POST array is empty. Here is my node code: ``` // simple end point just for testing exports.testPost = function(request, response) { data = request.body.data; postToPHP(data); response.end(data); } function postToPHP (data) { var http = require('http'); var options = { host : 'localhost', port : 8050, path : '/machines/test/index.php', method : 'POST', headers : { 'Content-Type' : 'application/json', 'Content-Length' : Buffer.byteLength(data) } }; var buffer = ""; var reqPost = http.request(options, function(res) { console.log("statusCode: ", res.statusCode); res.on('data', function(d) { console.info('POST Result:\n'); //process.stdout.write(d); buffer = buffer+data; console.info('\n\nPOST completed'); }); res.on('end', function() { console.log(buffer); }); }); console.log("before write: "+data); reqPost.write(data); reqPost.end(); } ``` Again, the request makes it to localhost:8050/machines/test/index.php but when I do a var_dump of $_POST it is an empty array. ``` [29-Jan-2014 21:12:44] array(0) { } ``` I suspect I am doing something wrong with the .write() method but I can't quite figure out what. Any input on what I am missing or doing incorrectly would be greatly appreciated. * Update: As some of the comments indicate using file_get_contents('php://input'); does work to get the data on the PHP side but I would still prefer to be able to access the $_POST array directly.
