Laravel 想要显示欢迎页面，尽管定义了“/”路由

Question

我正在学习 Laravel，完成后 this to-do task tutorial，我的应用程序仍然继续显示默认的欢迎页面。

为了防止开发人员摆脱默认内容的机制，我还删除了 resources/views/welcome.blade.php 文件。但这没有帮助。现在唯一不同的是我得到了：

InvalidArgumentException View [welcome] not found.

由 FileViewFinder 抛出。

根据教程，我的路线在 app/Http/routes.php 中定义为：

/**
 * Display all tasks
 */
Route::get('/', function(){
    $tasks = Task::orderBy('created_at', 'asc')->get();

    return view('tasks', [
        'tasks' => $tasks
    ]);
});

视图是在 resources/views/layouts/tasks.blade.php 中创建的。

不知道少了什么...

完整堆栈跟踪：

Answer 1

首先将 routes/web.php 的内容从 Route::get('/', function () { return view('welcome'); }); 到 Route::get('/', 'YourControllerName@functionName');

然后在控制器中：

public function functionName(){
$tasks = Task::orderBy('created_at', 'asc')->get();

    return view('layouts.tasks', [
        'tasks' => $tasks
    ]);
}

或者在同一个文件中 web.php 你可以这样做：

Route::get('/', function () { 
$tasks = \DB::table('tasks')->orderBy('created_at', 'desc')->get();
return view('layouts.tasks', [
        'tasks' => $tasks
    ]); 

});

希望有所帮助

Answer 2

return view('layouts.tasks', [
    'tasks' => $tasks
]);

因为您的视图在内部文件夹中，即布局

Answer 3

您没有遗漏任何内容，但您需要在视图函数中将任务替换为 return layouts.tasks'。

return view('layouts.tasks', [
    'tasks' => $tasks
]);

Answer 4

有一个 web.php 文件，确保将所有路由放在那里

另外，我遇到了和你一样的问题，通过清除路由缓存解决了这个问题运行

Answer 5

我遇到了同样的问题，刚刚解决了。运行这个命令应该有帮助：

php artisan optimize:clear

清除所有缓存。
