Android WebView App Laravel“该页面由于不活动而过期”



我刚刚为我的平台创建了一个简单的Android应用程序（WebView）。在台式机上的任何浏览器中都可以很好地工作，但我在Android应用程序上有一个问题。

我有以下情况：

  1. 打开应用程序 - 登录仪表板 - 注销（几秒钟或几分钟后） - 重定向到登录页面（这是正常）
  2. 打开应用程序 - 登录仪表板 - 关闭应用程序 - 段（30分钟或更长时间）后再次打开应用 - 无需再次登录，我直接将其重定向到仪表板 - 我正在尝试注销，我被重定向到仪表板 - 我正在尝试再次注销，并且我得到了"由于不活动，该页面已过期"。

注销代码：

<li class="dropdown dropdown-notification nav-item">
              <a class="nav-link nav-link-label" value="{{ csrf_token() }}" href="{{ url('/logout') }}" method="GET" onclick="event.preventDefault(); document.getElementById('logout-form').submit();"><font color="red"><i class="ficon ft-log-out"></i></font></a>
            </li>
            
             <form id="logout-form" action="{{ url('/logout') }}" method="POST" style="display: none;">
                                        {{ csrf_field() }}
                                    </form>

on/resources/views/errors我试图用html meta重定向修改419.blade.php，但问题尚未解决。

我想让我的客户登录仪表板很长时间，同时也可以在他们想要的情况下注销时可以注销。

您应该删除此行：

        webView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);

使用：

webView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
