I’m building REST web app and my server side Java code expects request body

  • 0

I’m building REST web app and my server side Java code expects request body to have pure JSON string.
My goal is to use regular HTTP POST method (not ajax) and set JSON into request body message.

If I use ajax, it is very simple. Something like:

var jsonInput = '{"foo":"bar"}';
ajaxRequest.setRequestHeader("Content-Type", "application/json");
ajaxRequest.send(jsonInput)

But I want to use regular HTTP POST.

Looking at the thread below, the answer is to create a form with hidden input field and put JSON in to the input field and have server side code handle the rest.

JavaScript post request like a form submit

I tried that and it works just fine but do I really have to bother creating new form and input field to accomplish this? Or is there any other way available?

NOTE: I don’t want to use JQuery or Prototype framework. Just simple Javascript.

    FORMs only allow for name-value pairs to be submitted, and so your JSON needs to be inserted into one such pair.

    Yout can read about this at w3.org

    As a solution, what about using xhr to send the data to the server, exchange it for some token, and then direct the user via a regular GET to a url passing the token?

    This should fit with the REST paradigm too.
