Play Framework 2.5 Form submit using POST method Error

Question

I have new to Play Framework 2.5. I am using Play in Java. Created a normal HTML form and want to submit the form using POST method but it throws error. I googled a lot but not succeed.

routes:

POST     /output     controllers.HomeController.result

HTML Code:

    <form name="form1" action="/output" method="post">
        <div id="content">
            <label>Enter Sentence/Paragraph.</label></br>
            <textarea id="para" name="para" rows="15" cols="100"></textarea></br>
            <input id="submit_btn" name="submit_btn" type="submit" value="Submit" />
        </div>
    </form>

Controller:

package controllers;

import com.google.inject.Inject;
import play.data.DynamicForm;
import play.data.FormFactory;
import play.mvc.Controller;
import play.mvc.Result;
import views.html.index;
import views.html.output;.

public class HomeController extends Controller {

    @Inject
    FormFactory formFactory;

    public Result index() {
        return ok(index.render("NLP Pipeline."));
    }

    public Result result() {
        DynamicForm requestData = formFactory.form().bindFromRequest();
        System.out.println("form: " + requestData.get("para"));
        return ok();
    }

}

Error:

I want to use normal HTML form to submit request using POST method. Any help please ?

Answer 1

I have the solution of my answer.

We can get the form post data in Play framework 2.5 by

final Map<String, String[]> form_values = request().body().asFormUrlEncoded();

and then get the form name parameter value by:

form_values.get("<key_name>")[0];
