Add parameters to HTTP POST request in Node.JS

Question

I've known the way to send a simple HTTP request using Node.js as the following:

var http = require('http');

var options = {
  host: 'example.com',
  port: 80,
  path: '/foo.html'
};

http.get(options, function(resp){
  resp.on('data', function(chunk){
    //do something with chunk
  });
}).on("error", function(e){
  console.log("Got error: " + e.message);
});

I want to know how to embed parameters in the body of POST request and how to capture them from the receiver module.

Solution

Would you mind using the request library. Sending a post request becomes as simple as

var options = {
url: 'https://someurl.com',
'method': 'POST',
 'body': {"key":"val"} 

};

 request(options,function(error,response,body){
   //do what you want with this callback functon
});

The request library also has a shortcut for post in request.post method in which you pass the url to make a post request to along with the data to send to that url.

Edit based on comment

To "capture" a post request it would be best if you used some kind of framework. Since express is the most popular one I will give an example of express. In case you are not familiar with express I suggest reading a getting started guide by the author himself.

All you need to do is create a post route and the callback function will contain the data that is posted to that url

app.post('/name-of-route',function(req,res){
 console.log(req.body);
//req.body contains the post data that you posted to the url 
 });

if you are new to this, don't even try to accomplish this with http code module instead more friendly frameworks like express or other modules.

That's is great but how to capture these body parameter in the receiver side ?
