在Userfrosting

Question

我试图使用内置的Slim编写器，但到目前为止还没有成功。

这就是我正在尝试的，但我收到了错误。

1. 更改为config_userfrosting.php：

   /*Create a log writer */
   
   $logWriter = new \UserFrosting\LogWriter(fopen('C:\xampp\htdocs\userfrosting\log\dev_logfile.log', 'a'));
   
   $app->configureMode('dev', function () use ($app, $public_path, $uri_public_root) {
   $app->config([
       'log.enable' => true,
       'log.writer' => $logWriter,
       'debug' => false,
   

2. 从index.php调用日志编写器：

$ app-＆gt; log-＆gt; debug（＆＃34;这是来自记录器的测试...＆＃34;）;

收到错误：

  PHP Notice:  Undefined variable: logWriter in \\userfrosting\\config-userfrosting.php on line 33

为了在闭包（configureMode）中访问变量，您需要使用use(...)参数列表传递它：

$app->configureMode('dev', function () use ($app, $public_path, $uri_public_root, $logWriter) {

    $app->config([
        'log.enable' => true,
        'log.writer' => $logWriter,
        'debug' => false,
        ...
});
