Java post http request (express) REST api

Having some troubles communicating with a Express REST api through Java.

A simple route which is online at: http://localhost:5555/test

router.post('/test', function (req, res, next) {
  console.log("recived request");
  res.sendStatus(200);
});

As you can see, this route doesn't do much tho, only for connection testing purpose.

Spending like hours searching but didn't find a good example yet.

Still got this peace of code but got exception.

URL url = new URL("http://localhost:5555/test");
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("POST");
connection.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
writer.write("test");

If someone knows a peace of code I could work, that would be great!

Thanks

Edit Server is running:

> node index.js
server running on port: 5555
connection open

Exception from Java:

System.err: null

Because your route accepts POST method, you may have 2 options.

  1. Change your request method in Java code to POST 

    connection.setRequestMethod("POST");

  2. Change your route accepts GET

Your Express route is expecting a POST and your code does a GET request (openConnection). Try to change it to get an retry your operation.
