I'm trying to allow javascript to communicate with a Node.js server.
POST request (web browser)
var http = new XMLHttpRequest(); var params = "text=stuff"; http.open("POST", "http://someurl.net:8080", true); http.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http.setRequestHeader("Content-length", params.length); http.setRequestHeader("Connection", "close"); alert(http.onreadystatechange); http.onreadystatechange = function() { if (http.readyState == 4 && http.status == 200) { alert(http.responseText); } } http.send(params); Right now the Node.js server code looks like this. Before it was used for GET requests. I'm not sure how to make it work with POST requests.
Server (Node.js)
var server = http.createServer(function (request, response) { var queryData = url.parse(request.url, true).query; if (queryData.text) { convert('engfemale1', queryData.text, response); response.writeHead(200, { 'Content-Type': 'audio/mp3', 'Content-Disposition': 'attachment; filename="tts.mp3"' }); } else { response.end('No text to convert.'); } }).listen(8080); Thanks in advance for your help.

POST request (web browser) var http = new XMLHttpRequest(); var params = "text=stuff"; http. open("POST", "http://someurl.net:8080", true); http. setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http. setRequestHeader("Content-length", params.
Example code: var request = require('request') var options = { method: 'post', body: postData, // Javascript object json: true, // Use,If you are sending JSON data url: url, headers: { // Specify headers, If any } } request(options, function (err, res, body) { if (err) { console. log('Error :', err) return } console.
Your code is non-blocking because it uses non-blocking I/O with the request() function. This means that node. js is free to service other requests while your series of http requests is being fetched.
Node. js uses JavaScript on the server. The task of a web server is to open a file on the server and return the content to the client.
The following code shows how to read values from an HTML form. As @pimvdb said you need to use the request.on('data'...) to capture the contents of the body.
const http = require('http') const server = http.createServer(function(request, response) { console.dir(request.param) if (request.method == 'POST') { console.log('POST') var body = '' request.on('data', function(data) { body += data console.log('Partial body: ' + body) }) request.on('end', function() { console.log('Body: ' + body) response.writeHead(200, {'Content-Type': 'text/html'}) response.end('post received') }) } else { console.log('GET') var html = ` <html> <body> <form method="post" action="http://localhost:3000">Name: <input type="text" name="name" /> <input type="submit" value="Submit" /> </form> </body> </html>` response.writeHead(200, {'Content-Type': 'text/html'}) response.end(html) } }) const port = 3000 const host = '127.0.0.1' server.listen(port, host) console.log(`Listening at http://${host}:${port}`) If you use something like Express.js and Bodyparser then it would look like this since Express will handle the request.body concatenation
var express = require('express') var fs = require('fs') var app = express() app.use(express.bodyParser()) app.get('/', function(request, response) { console.log('GET /') var html = ` <html> <body> <form method="post" action="http://localhost:3000">Name: <input type="text" name="name" /> <input type="submit" value="Submit" /> </form> </body> </html>` response.writeHead(200, {'Content-Type': 'text/html'}) response.end(html) }) app.post('/', function(request, response) { console.log('POST /') console.dir(request.body) response.writeHead(200, {'Content-Type': 'text/html'}) response.end('thanks') }) const port = 3000 app.listen(port) console.log(`Listening at http://localhost:${port}`) Receive POST and GET request in nodejs :
1).Server
var http = require('http'); var server = http.createServer ( function(request,response){ response.writeHead(200,{"Content-Type":"text\plain"}); if(request.method == "GET") { response.end("received GET request.") } else if(request.method == "POST") { response.end("received POST request."); } else { response.end("Undefined request ."); } }); server.listen(8000); console.log("Server running on port 8000"); 2). Client :
var http = require('http'); var option = { hostname : "localhost" , port : 8000 , method : "POST", path : "/" } var request = http.request(option , function(resp){ resp.on("data",function(chunck){ console.log(chunck.toString()); }) }) request.end(); If you love us?
