尝试访问此 URL 'users/login' 时出现该错误，这是我的代码：
View users/login.blade.php :
查看 users/login.blade.php ：
<head>Sign in : </head>
<body>
{{ HTML::ul($errors->all()) }}
<?php echo Form::open(array('url' => 'users'));
echo '<div class="form-group">';
echo Form::label('username', 'User Name');
echo Form::text('ausername', null, array('class' => 'form-control'));
echo '</div>';
echo '<div class="form-group">';
echo Form::label('Password', 'Password');
echo Form::password('apassword', null, array('class' => 'form-control'));
echo '</div>';
echo Form::submit('Sign in', array('class' => 'btn btn-primary'));
echo Form::close();
?>
</body>
Controller Usercontroller.php
控制器 Usercontroller.php
<?php
class UserController extends BaseController {
public function index()
{
$users = User::all();
return View::make('users.index')
->with('users', $users);
}
public function create()
{
return View::make('users.create');
}
public function store()
{
$rules = array(
'username' => 'required|alpha_dash',
'password' => 'required|confirmed',
'name' => 'required|regex:/^[a-zA-Z][a-zA-Z ]*$/',
'email' => 'required|email|unique:users',
'country' => 'required'
);
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails()) {
return Redirect::to('users/create')
->withErrors($validator)
->withInput(Input::except('password'));
} else {
$user = new User;
$user->username = Input::get('username');
$user->password = Hash::make(Input::get('password'));
$user->name = Input::get('name');
$user->email = Input::get('email');
$user->country = Input::get('country');
$user->save();
// redirect
Session::flash('message', 'Successfully created user!');
return Redirect::to('users');
}
}
public function login()
{
$reflector = new ReflectionClass("UserController");
$fn = $reflector->getFileName();
dd($fn);
return View::make('users.login');
}
public function authen()
{
if (Auth::attempt(array('username' => Input::get('ausername'), 'password' => Input::get('apassword'))))
{
return Redirect::intended('users');
}
}
}
and my routes.php
和我的routes.php
<?php
Route::resource('users','UserController');
Route::get('users/login', 'UserController@login');
Route::get('/', function()
{
return View::make('hello');
});
is it a route problem, thank you for the help
是不是路线问题，谢谢帮忙

I have experienced the same problem as you. The problem ends up with rearranging the resource code, i.e.
我遇到了和你一样的问题。问题最终以重新排列资源代码，即
Route::get('masterprices/data', 'MasterPriceController@data');
Route::get( 'masterprices/upload', 'MasterPriceController@upload');
Route::post('masterprices/upload', 'MasterPriceController@do_upload');
Route::get('masterprices/{masterprices}/multipledelete', 'MasterPriceController@multipledelete');
Route::resource('masterprices', 'MasterPriceController');
It checks the other possible handler, if none it will reach the last line which is resource to handle index page.
它检查其他可能的处理程序，如果没有，它将到达处理索引页的资源的最后一行。

This one:
这个：
Route::resource('users','UserController');
defines following routes:
定义以下路由：
| GET|HEAD users | users.index | UsersController@index
| GET|HEAD users/create | users.create | UsersController@create
| POST users | users.store | UsersController@store
| GET|HEAD users/{users} | users.show | UsersController@show
| GET|HEAD users/{users}/edit | users.edit | UsersController@edit
| PUT users/{users} | users.update | UsersController@update
| PATCH users/{users} | | UsersController@update
| DELETE users/{users} | users.destroy | UsersController@destroy
So URI users/login calls users.show route and that's the problem.
所以 URI users/login 调用 users.show 路由，这就是问题所在。
Solution is like Kryten said to remove that route completely, but I suppose you still want to use some of the routes for the resource, like in your controller (create, store, index), so better use this:
解决方案就像 Kryten 所说的完全删除该路由，但我想您仍然希望使用一些路由来获取资源，例如在您的控制器中（创建、存储、索引），所以最好使用这个：
Route::resource('users', 'UserController', ['only'=> ['index','create','store']]);
回答by Kryten
The problem list with the Route::resourcecall. By including that statement, you're telling Laravel that you want to use a RESTful controller for paths that start with users. This means that when you hit the URL 'users/login', the RESTful controller interprets that as a "show" action for the usercontroller and fails, since there's no showmethod. See http://laravel.com/docs/controllers#resource-controllersfor details - the table on that page explains what routes are automatically configured when you implement a resource controller.
Route::resource呼叫的问题列表。通过包含该语句，您告诉 Laravel 您希望对以users. 这意味着当您点击 URL 'users/login' 时，RESTful 控制器会将其解释为控制器的“显示”操作user并失败，因为没有show方法。有关详细信息，请参阅http://laravel.com/docs/controllers#resource-controllers- 该页面上的表格解释了实现资源控制器时自动配置的路由。
The solution is to remove Route::resource('users','UserController');.
解决方法是删除Route::resource('users','UserController');.

Add the custom route before the resource routes in your routes file.
在路由文件中的资源路由之前添加自定义路由。
As per Laravel documentation:
根据 Laravel 文档：
If it becomes necessary to add additional routes to a resource controller beyond the default resource routes, you should define those routes before your call to Route::resource; otherwise, the routes defined by the resource method may unintentionally take precedence over your supplemental routes:
如果需要在默认资源路由之外向资源控制器添加其他路由，则应在调用 Route::resource 之前定义这些路由；否则，资源方法定义的路由可能会无意中优先于您的补充路由：

The simple solution is one I just found after reading your question. Define your ::resourceroutes afterany ::getor ::postroutes. I just tested on 4.2 and it's working (after having the same issue).
简单的解决方案是我在阅读您的问题后刚刚找到的解决方案。定义你的::resource路线后，任何::get或::post途径。我刚刚在 4.2 上进行了测试并且它正在工作（在遇到同样的问题之后）。

I was having same issue but it was weird one. In my routes file I had:
我遇到了同样的问题，但很奇怪。在我的路线文件中，我有：
Route::controller('carts', 'CartsApiController');
When I changed it to:
当我将其更改为：
Route::controller('cart', 'CartsApiController');
Everything was fine and I did not have the error again. I am not sure but seems like some naming issue.
一切都很好，我没有再次出现错误。我不确定，但似乎有些命名问题。
回答by Devil Inside
I also have faced the same problem but i found it very dumb and silly mistake one use route like this : -
我也遇到了同样的问题，但我发现它非常愚蠢和愚蠢的错误使用这样的路线：-
Route::get('users/login', ['uses'=>'UserController@login', 'as'=> 'userLogin']);
and in your view or controller use route('userLogin'); for route to that particular function in your controller
并在您的视图或控制器中使用 route('userLogin'); 用于路由到控制器中的特定功能
