Question

我正在使用laravel 4.2（PHP 5.4.25）开发一个Web应用程序作为后端框架。

当我从IDE运行我的索引页面时，它会返回我预期的第一个视图，但是当我从浏览器中调用它时，它会向我显示此错误：

substr() expects parameter 1 to be string, object given

这是错误的屏幕

enter image description here

这是我的路线档案：

<?php

// Route to home page
Route::get('/', array('as' => 'home', function () {
    Log::debug('**** Load home page view');
    if ( Auth::check() ) {
        return View::make('dashboard');
    } else {
        return View::make('login');
    }
}));

我已经在根目录中提取了laravel的公共文件夹的内容，并在我更新了启动文件的路径之后。但是，如果在IDE（PHPStorm）中运行索引文件，则可以正常工作并返回登录视图。

登录视图：

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Login</title>
</head>
<body>

</body>
</html>

仪表板视图：

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Dashboard</title>
</head>
<body>

</body>
</html>

我错了什么？

编辑：问题出在app/config/session.php文件中，我使用原始laravel文件更改了该文件，一切正常。

这是我错误的配置会话文件：

由于

Answer 1

通过转储错误，这在您的视图中不是问题，但在某种程度上，在您的数据库连接中。数据库管理器无法解析您的数据库连接名称。这可能是由Auth::check()引起的。检查数据库是否配置正确。

Answer 2

问题发生在app/config/session.php。

我已将'connection' => DB::connection('mysql'),替换为'connection' => null,，一切正常。

Laravel不加载我的观点
