Android WebView无法正常加载wolt登录页https://wolt.com/sk/login求助

我尝试在Android应用中加载https://wolt.com/sk/login页面并实现自动登录，但该URL无法在WebView中正常加载。我也尝试使用Android-AdvancedWebView，问题依旧。以下是我的WebView配置代码：

WebSettings webSettings = webView.getSettings();
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);

webView.getSettings().setSupportZoom(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setDisplayZoomControls(false);
webView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
webView.setScrollbarFadingEnabled(false);
if (android.os.Build.VERSION.SDK_INT >= 21) {
    CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
} else {
    CookieManager.getInstance().setAcceptCookie(true);
}

webView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
String ua = "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/20100101 Firefox/4.0";
webView.getSettings().setUserAgentString(ua);
webSettings.setDomStorageEnabled(true);
webSettings.setJavaScriptEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
webView.getSettings().setDomStorageEnabled(true); // enable DOM storage
webView.getSettings().setAllowFileAccess(true); // allow access to file system
webView.getSettings().setAllowFileAccessFromFileURLs(true); // allow access to file system from file URLs
webView.getSettings().setAllowUniversalAccessFromFileURLs(true); // allow access to file system from any URLs
webView.getSettings().setBuiltInZoomControls(false);
webView.getSettings().setSupportZoom(false);
webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webView.getSettings().setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);

CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);

WebViewClientImpl webViewClient = new WebViewClientImpl(this);
webView.setWebViewClient(new WebViewClient() {

    @SuppressWarnings("deprecation")
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        Log.i("webview", "loading: deprecation");
        return  true;
        //return super.shouldOverrideUrlLoading(view, url);
    }

    @Override
    @TargetApi(Build.VERSION_CODES.N)
    public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
        view.loadUrl(request.getUrl().toString());
        Log.i("webview", "loading: build.VERSION_CODES.N");
        return true;
        //return super.shouldOverrideUrlLoading(view, request);
    }

    @Override
    public void onPageStarted(
            WebView view, String url, Bitmap favicon) {
       Log.i("webview", "page started:"+url);
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public void onPageFinished(WebView view, final String url) {

        Log.i("webview", "page finished:"+url);

    }

    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError er) {
        handler.proceed();
    }

});
webView.setWebChromeClient(new WebChromeClient());

CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);

webView.loadUrl("https://wolt.com/sk/login");
// use cookies to remember a logged in status
 cookieManager.setAcceptCookie(true);

以下是针对性的修复建议：

• 清理重复配置：移除代码中重复的设置项（如两次setJavaScriptEnabled(true)、先开启缩放后关闭的冲突配置），避免配置逻辑冲突。
• 更新User-Agent：当前使用的老旧Firefox UA可能被网站拦截，建议使用系统默认UA或贴近现代浏览器的UA：

  String ua = webView.getSettings().getUserAgentString() + " YourAppName/1.0";
  webView.getSettings().setUserAgentString(ua);
  

• 修正URL拦截逻辑：当前强制拦截所有URL并重新加载会破坏页面跳转逻辑，仅拦截非HTTP/HTTPS的自定义Scheme链接即可：

  @SuppressWarnings("deprecation")
  @Override
  public boolean shouldOverrideUrlLoading(WebView view, String url) {
      if (!url.startsWith("http://") && !url.startsWith("https://")) {
          // 处理自定义Scheme逻辑
          return true;
      }
      return super.shouldOverrideUrlLoading(view, url);
  }
  
  @TargetApi(Build.VERSION_CODES.N)
  @Override
  public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
      String url = request.getUrl().toString();
      if (!url.startsWith("http://") && !url.startsWith("https://")) {
          // 处理自定义Scheme逻辑
          return true;
      }
      return super.shouldOverrideUrlLoading(view, request);
  }
  

• 规范Cookie与存储配置：简化Cookie设置逻辑，补充低版本Android的数据库路径配置：

  webSettings.setDomStorageEnabled(true);
  webSettings.setDatabaseEnabled(true);
  if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
      webSettings.setDatabasePath(getApplicationContext().getFilesDir().getPath() + "/databases");
  }
  CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
  

• 修复SSL错误处理：避免直接忽略SSL错误，添加用户确认逻辑保障安全：

  @Override
  public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError er) {
      new AlertDialog.Builder(view.getContext())
          .setTitle("SSL证书异常")
          .setMessage("该网站证书存在问题，是否继续访问？")
          .setPositiveButton("继续", (dialog, which) -> handler.proceed())
          .setNegativeButton("取消", (dialog, which) -> handler.cancel())
          .show();
  }
  

• 确认网络权限：确保Manifest中已添加网络权限：

  <uses-permission android:name="android.permission.INTERNET" />
