Question

我是laravel的新手，我正在尝试制作自己的登录和注册表单，以便用户可以登录和注册，我的注册表单可以正常工作，它可以收集数据并将其存储在数据库中，但是每当我尝试使用相同的数据，它也给我这个错误。我可以尝试多种方法，但失败了。谢谢。...

错误：找不到“ App \ Controllers \ controller”类

我的HTML：

@extends("layouts.master")

@section('title')
My page
@endsection

@section('content')
<div class="row">
<div class="col-md-6">
<h3>Sign-Up</h3>
<form action="{{route('signup')}}" method="post">

<div class="form-group">
<label for="email">Your email</label>
<input class="form-control" type="text" name="email" id="email">
</div>

<div class="form-group">
<label for="first_name">First Name</label>
<input class="form-control" type="text" name="first_name" id="first_name">
</div>

<div class="form-group">
<label for="password">Password</label>
<input class="form-control"  type="password" name="password" id="password">
</div>

<button type="sumbit" class="btn btn-primary">sumbit</button>
<input type="hidden" name="_token" value="{{ Session::token() }}">

</form>
</div>

<div class="col-md-6">
<h3>Login </h3>

控制器：

<?php
namespace App\Controllers;

use App\Http\Requests;
use App\User;
use App\UserTypes;

use Auth;
use Hashids;
use Redirect;
use Request;

Answer 1

您的名称空间对于访问Controllers文件夹是错误的，控制器文件上的代码的第一行更改了：

namespace App\Controllers;

到

namespace App\Http\Controllers;

如果有此错误（Cannot use object of type Illuminate\Support\Facades\Request as array），也请更改此部分：

use Request;  to  use Illuminate\Http\Request;

和

$email = $request['email'];
$first_name = $request['first_name'];
$password = bcrypt($request['password']);

到

$email = $request->email;
 $first_name = $request->first_name;
 $password = bcrypt($request->password);

Answer 2

默认情况下，laravel将控制器放在

下

app\Http\Controllers

因此，将namespace App\Controllers;替换为namespace App\Http\Controllers;

编辑：

访问请求变量，如下所示：

 $email = $request->input('email');
 $first_name = $request->input('first_name');
 //similar way for other inputs

Answer 3

$request是一个对象，因此您可以使用->获取属性。如下更改控制器代码：

<?php
namespace App\Http\Controllers; // HERE

use Illuminate\Http\Request; // FOR YOUR COMMENT
use App\Http\Requests;
use App\User;
use App\UserTypes;

use Auth;
use Hashids;
use Redirect;
use Request;
use Hash;



class UserController extends controller
{
    public function getdashboard()
    {
        return view('dashboard');
    }

    public function postSignUp(Request $request)
    {
        $email = $request->email;// HERE
        $first_name = $request->first_name;// HERE
        $password = bcrypt($request->password);// HERE


        $user = new User();
        $user->email = $email;
        $user->first_name = $first_name;
        $user->password = $password;

        $user->save();
        return redirect()->route('dashboard');
    }
    public function postSignIn(Request $request)
    {
        if(Auth::attempt([ 'email' => $request->email,'password' => $request->password])){// HERE
            return redirect()->route('dashboard');
        }
        return redirect()->back();
    }
}

我想在此处链接一些laravel usage samples，并且在Controller有一个名为App\Http\Controllers\Controller的类，您需要将其用作基类。，但总之，只需将控制器名称空间从App\Controllers更改为App\Http\Controllers，或者甚至可以为自己实现Controller类，如下所示：

<?php
namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

use App\User;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\File;
use Illuminate\Support\Facades\Storage;

class UserController extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    public function postSignUp(Request $request)
    {
        $this->validate($request, [
            'email' => 'required|email|unique:users',
            'first_name' => 'required|max:120',
            'password' => 'required|min:4'
        ]);
        $email = $request['email'];
        $first_name = $request['first_name'];
        $password = bcrypt($request['password']);
        $user = new User();
        $user->email = $email;
        $user->first_name = $first_name;
        $user->password = $password;
        $user->save();
        Auth::login($user);
        return redirect()->route('dashboard');
    }
    public function postSignIn(Request $request)
    {
        $this->validate($request, [
            'email' => 'required',
            'password' => 'required'
        ]);
        if (Auth::attempt(['email' => $request['email'], 'password' => $request['password']])) {
            return redirect()->route('dashboard');
        }
        return redirect()->back();
    }
    public function getLogout()
    {
        Auth::logout();
        return redirect()->route('home');
    }
    public function getAccount()
    {
        return view('account', ['user' => Auth::user()]);
    }
    public function postSaveAccount(Request $request)
    {
        $this->validate($request, [
           'first_name' => 'required|max:120'
        ]);
        $user = Auth::user();
        $old_name = $user->first_name;
        $user->first_name = $request['first_name'];
        $user->update();
        $file = $request->file('image');
        $filename = $request['first_name'] . '-' . $user->id . '.jpg';
        $old_filename = $old_name . '-' . $user->id . '.jpg';
        $update = false;
        if (Storage::disk('local')->has($old_filename)) {
            $old_file = Storage::disk('local')->get($old_filename);
            Storage::disk('local')->put($filename, $old_file);
            $update = true;
        }
        if ($file) {
            Storage::disk('local')->put($filename, File::get($file));
        }
        if ($update && $old_filename !== $filename) {
            Storage::delete($old_filename);
        }
        return redirect()->route('account');
    }
    public function getUserImage($filename)
    {
        $file = Storage::disk('local')->get($filename);
        return new Response($file, 200);
    }
}

请注意，PHP对于类命名不区分大小写，但是您可以使用和扩展\App\Http\Controllers\Controller而不是仅仅controller

“找不到类'App \ Controllers \ controller'”
