Send URL-encoded parameters in Node.js using request module

Rename the qs key to form in the object. The qs key is for specifying the query string on the end of the URL (e.g. For GET requests). The form key is for specifying the form URL encoded request body (e.g. For a POST request).

the same issue for me and my resolution which is perfectly working for me is.

request.post({
headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
},
url : "http://pastebin.com/api/api_post.php",
body : "api_dev_key=MY_DEV_KEY&api_option=paste&api_paste_code=andom text"},function(err,res,body){  ...});
