Many issues related to webAPI.getURLQueryParams()

[ctoabidmaqbool]

1. When first load page getURLQueryParams() return empty parms e.g. {}

2. When page is refresh then getURLQueryParams() return correct parms e.g. {category=xyz}

3. When another page is opened e.g. /info?content=abc previous parms are showing e.g. {category=xyz}

Please Try to fix this error / issue

The WebAPI only shows the parameters of the start of the application. If you are using jpro-web (or now named jpro-routing), you can access the changed query-parameters by parsing the URL of the page in the route. But we are currently also redesigning the framework - to directly provide the query parameters as a Map (and many many more improvements)

Hi! Devs, It's a long time of waiting period!

Still issue of webAPI.getURLQueryParams() is not resolved.

Is currently there is only way to get URL Query Parameters using JavaScript? Or there is anything I am missing?

In the above code clicking Get Parm button shows null value, if firstly this URL is opened e.g. 'https://localhost:8080'

package com.jpro.hellojpro;

import com.jpro.routing.LinkUtil;
import com.jpro.routing.Route;
import com.jpro.routing.RouteApp;
import com.jpro.routing.View;
import com.jpro.webapi.WebAPI;
import javafx.geometry.Pos;
import javafx.scene.Node;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

import static com.jpro.routing.RouteUtils.get;
import static com.jpro.routing.RouteUtils.redirect;

public class App extends RouteApp {
    private Stage pStage;

//    public static void main(String[] args) {
//        launch(args);
//    }

    @Override
    public void start(Stage pStage) {
        this.pStage = pStage;
        super.start(pStage);

//        SessionManager sessionManager = SessionManager.getDefault(getRouteNode(), getStage());
//        sessionManager.start();
    }

    @Override
    public Route createRoute() {
        return Route.empty()
                .and(redirect("/", "/info"))
                .and(get("/info", (r) -> new InfoPage(pStage)));
    }
}

class InfoPage extends View {
    private Stage pStage;

    public InfoPage(Stage pStage) {
        this.pStage = pStage;
    }

    @Override
    public String title() {
        return "Sample JPro Page";
    }

    @Override
    public String description() {
        return "This is a simple page where JPro testing done.";
    }

    @Override
    public Node content() {
        VBox root = new VBox(10);
        root.setAlignment(Pos.CENTER);
        root.setPrefSize(500, 1000);

//        Label lblText2 = new Label("Home");
//        LinkUtil.gotoPage(lblText, "/");

        Label lblText2 = new Label("Info with Parm");
        LinkUtil.setLink(lblText2, "/info?q=About");

        Button btnGetParm = new Button("Get Parm");
        btnGetParm.setOnAction(event -> {
            System.out.println("q: " + WebAPI.getWebAPI(pStage).getURLQueryParams().get("q"));
        });

        if (WebAPI.getWebAPI(pStage).getURLQueryParams().get("q") != null) {
            btnGetParm.fire();
        }

        root.getChildren().addAll(lblText2, btnGetParm);

        return root;
    }
}

The Request contains all the information you need.

.and(get("/info", (r) -> new InfoPage(pStage)));

The r parameter is the request. It contains all the query parameters and other information, which might be interesting to you.

Currently, the WebAPI only contains the initial query parameters - which is usually interesting for applications, which don't use the routing.

Okay, Something like this codding solved out the my issues related to Get URL Query Parameters e.g. r.queryParameters()

package com.jpro.hellojpro;

import javafx.geometry.Pos;
import javafx.scene.Node;
import javafx.scene.control.Label;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
import one.jpro.routing.LinkUtil;
import one.jpro.routing.Route;
import one.jpro.routing.RouteApp;
import one.jpro.routing.View;
import simplefx.experimental.parts.FXFuture;

import static one.jpro.routing.RouteUtils.get;
import static one.jpro.routing.RouteUtils.redirect;

public class App extends RouteApp {
    private Stage pStage;

    @Override
    public void start(Stage pStage) {
        this.pStage = pStage;
        super.start(pStage);
    }

    @Override
    public Route createRoute() {
        return Route.empty()
                .and(r -> {
                    System.out.println("prams: " + r.queryParameters());
                    System.out.println("pram: q= " + r.queryParameters().get("q"));
                    System.out.println("pram: email= " + r.queryParameters().get("email"));

                    return FXFuture.unit(null);
                })
                .and(redirect("/", "/info"))
                .and(get("/info", (r) -> new InfoPage(pStage)));
    }
}

class InfoPage extends View {
    private Stage pStage;

    public InfoPage(Stage pStage) {
        this.pStage = pStage;
    }

    @Override
    public String title() {
        return "Sample JPro Page";
    }

    @Override
    public String description() {
        return "This is a simple page where JPro testing done.";
    }

    @Override
    public Node content() {
        VBox root = new VBox(10);
        root.setAlignment(Pos.CENTER);
        root.setPrefSize(500, 1000);

        Label lblText2 = new Label("Info with Parm");
        LinkUtil.setLink(lblText2, "/info?q=About&email=cto.ms@outlook.com");

        root.getChildren().addAll(lblText2);

        return root;
    }
}

I get these values in console when route contains values:

prams: Map(q -> About, email -> cto.ms@outlook.com)
pram: q= Some(About)
pram: email= Some(cto.ms@outlook.com)

The confusion is why r.queryParameters().get("q") returns Some(value) not simple value?

[ctoabidmaqbool]

prams: Map(q -> About, email -> cto.ms@outlook.com) pram: q= Some(About) pram: email= Some(cto.ms@outlook.com)

Okey!

System.out.println("pram: q= " + r.queryParameters().get("q").get());

Solve the issue, e.g. then Some(value) no longer will be returned rather only value will be returned.

For now, it's a Scala collection. It might change at some time, but it is what it is for now.
