node.js making https post request with x-www-form-urlencoded data
This code snippet is a demo of using node’s https and querystring to make a https post request with data encoded in x-www-form-urlencoded. The querystring module encodes the data in x-www-form-urlencoded and it is then passed in the req.write() to make the https post request. In the reqest headers, the Content-type has to be ‘application/x-www-form-urlencoded’ and the Content-Length has to be the length of the data that’s going to be transmitted in the request.
[code language=”javascript”]
var https = require(‘https’);
var querystring = require(‘querystring’);
// form data
var postData = querystring.stringify({
firstanme: "Amy",
lastname: "Li"
});
// request option
var options = {
host: ‘example.com’,
port: 443,
method: ‘POST’,
path: ‘/user’,
headers: {
‘Content-Type’: ‘application/x-www-form-urlencoded’,
‘Content-Length’: postData.length
}
};
// request object
var req = https.request(options, function (res) {
var result = ”;
res.on(‘data’, function (chunk) {
result += chunk;
});
res.on(‘end’, function () {
console.log(result);
});
res.on(‘error’, function (err) {
console.log(err);
})
});
// req error
req.on(‘error’, function (err) {
console.log(err);
});
//send request witht the postData form
req.write(postData);
req.end();
