尝试Yii2使用该basic app示例，但在路由方面遇到了一些问题。我有一个简单的登录表单，提交时调用了正确的控制器操作，但 $_POST 数据为空。在 Yii 调试器中，日志中的一切看起来都正常，除了这一行：
3 18:57:49.307 trace yii\web\Application::handleRequest Route requested: ''
路线处理不当，但我不知道下一步该尝试什么。“基本应用程序”带有一个登录表单视图，并且该表单的路由工作正常。这是我的表格：
<form class="navbar-form navbar-right" role="form" id="du-lts-rm-login-form" method="post">
<div class="form-group">
<input type="text" class="form-control" placeholder="DU ID number">
</div><br>
<div class="form-group">
<input type="text" class="form-control" placeholder="DU Password">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
这是完整的跟踪：
1 18:57:49.306 trace yii\base\Module::getModule Loading module: debug
2 18:57:49.307 trace yii\web\UrlManager::parseRequest Pretty URL not
enabled. Using default URL parsing logic.
3 18:57:49.307 trace yii\web\Application::handleRequest Route requested:
''
4 18:57:49.307 trace yii\base\Controller::runAction Route to run: site/index
5 18:57:49.307 trace yii\base\InlineAction::runWithParams Running action:
app\controllers\SiteController::actionIndex()
6 18:57:49.307 trace yii\base\View::renderFile Rendering view file:
/home/t/Documents/records/views/site/index.php
/home/t/Documents/records/controllers/SiteController.php (59)
7 18:57:49.307 trace yii\base\View::renderFile Rendering view file:
/home/t/Documents/records/views/layouts/main.php
/home/t/Documents/records/controllers/SiteController.php (59)
请求正文为空，但路由看起来正确：
Route 'site/index'
Action 'app\\controllers\\SiteController::actionIndex()'
同样在响应标头中，您可以在下面看到引用者不正确。应该看起来像'https://localhost/records/web/index.php?r=site/index'.
