Problema con JavaFx WebView

dev_java · 10 Novembre 2019

Buongiorno a tutti!!
Sono qui per esporvi un problema che sto avendo con la WebView di JavaFX:
Sto sviluppando una piccola applicazione in Java tramite la quale devo accedere al sito Nike Sneakrs (non sono sicuro di poterlo citare, nel caso non lo possa fare chiedo venia)
Il problema è che quando eseguo l'applicazione mi viene caricato il sito in una sua versione piuttosto scarna ed inoltre non riesco ad accedere dal sito principale (il quale però viene caricato correttamente)

lascio le immagini per rendere l'idea

Vi lascio qui il codice:

Main.java

Java:

package nikesnkrs;
import java.io.IOException;


import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;

public class Main extends Application{
    private static Stage primaryStage;
    private BorderPane rootLayout;
    @Override
    public void start(Stage primaryStage) {
        this.primaryStage=primaryStage;
        this.primaryStage.setTitle("Nike Sneakers 2019");
        initLayout();
    }
   
    public void initLayout(){
        try{
            FXMLLoader loader= new FXMLLoader();
            loader.setLocation(Main.class.getResource("view/layout.fxml"));
            rootLayout=(BorderPane) loader.load();
            Scene scene=new Scene(rootLayout);
            primaryStage.setScene(scene);
            primaryStage.show();
        }catch (IOException e){
            e.printStackTrace();
        }
    }
    public static Stage getPrimaryStage() {
        return primaryStage;
    }
    public static void main(String[] args){
        launch(args);
    }

}

layoutController.java

Java:

package nikesnkrs.view;

import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebHistory;
import javafx.scene.web.WebView;

import java.net.URL;
import java.util.ResourceBundle;

import javafx.collections.ObservableList;
import javafx.event.ActionEvent;

public class layoutController implements Initializable{
    @FXML
    private WebView webview;

   
    private WebEngine webEngine;
    private WebHistory history;
    private ObservableList<WebHistory.Entry> entries;
   
    @Override
    public void initialize(URL location, ResourceBundle resources) {
        loadSite();
       
    }
   
    @FXML
    public void ricarica(ActionEvent event) {
        loadSite();
    }
   
   
   
    @FXML
    public void indietro(ActionEvent event) {
        history = webEngine.getHistory();
        entries = history.getEntries();
        history.go(-1);
    }
   
   
    private void loadSite() {


        webEngine = webview.getEngine();
        webEngine.setUserAgent("Mozilla/5.0 (X11; Linux x86_64)");
        webEngine.setJavaScriptEnabled(true);
        webEngine.load("https://www.nike.com/it/launch/");  
       
       
       
    }
   
}

Spero di essere stato chiaro e ringrazio infinitamente tutti coloro che mi aiuteranno
:thanks:

Riscrivi in questo modo il metodo loadSites() della classe layoutController.java

Java:

private void loadSite() {


        webEngine = webview.getEngine();
        webEngine.setUserAgent("Mozilla/5.0 (X11; Linux x86_64)");
        webEngine.setJavaScriptEnabled(true);
        //Log del sito
        com.sun.javafx.webkit.WebConsoleListener.setDefaultListener(
                    (webView, message, lineNumber, sourceId)-> System.out.println("Console: [" + sourceId + ":" + lineNumber + "] " + message)
               );
        webEngine.load(site);  
       
       
       
    }

Poi posta quello che ti verrà stampato nel terminale (il log del sito) quando carichi la pagina

Allora questo è quello che mi viene quando provo a caricare la pagina "scarna":

Questo invece è quello che mi viene quando provo ad accedere:

Mmmm prova a inserire questo codice nel Main del programma:

Java:

System.setProperty("sun.net.http.allowRestrictedHeaders", "true");

Niente da fare, non cambia nulla :cry:

Allora non quale sia il problema...
Attendi l'opinione di qualcun'altro
