laravel - Laravel API：Illuminate\Contracts\Container\BindingResolutionException：目标类

问题描述

我正在研究 API。我想创建登录 api。我在控制器中的 API 文件夹中创建了 UsersController。当我在邮递员中运行时，我显示错误

Illuminate\Contracts\Container\BindingResolutionException: Target class [App\Http\Controllers\App\Http\Controllers\API\UsersController] does not exist. in file F:\University_Data\xamp\htdocs\stylooworld\vendor\laravel\framework\src\Illuminate\Container\Container.php on line 835`

我现在不明白为什么它重复了路由路径目标类[App\Http\Controllers\App\Http\Controllers\API\UsersController]

api.php

<?php

use Illuminate\Http\Request;

use Illuminate\Support\Facades\Route;
/*
|--------------------------------------------------------------------------
| API Routes
|--------------------------------------------------------------------------
|
| Here is where you can register API routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| is assigned the "api" middleware group. Enjoy building your API!
|
*/

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});


Route::namespace('App\Http\Controllers\API')->group(function () {

    Route::post('login', 'UsersController@loginUser');
});

用户控制器.php

<?php

namespace App\Http\Controllers\API;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Http\Controllers\UserController;

class UsersController extends Controller
{
    //
    public function loginUser(Request $request)
    {
        if ($request->isMethod('post')) {
            $data = $request->all();
            echo "<pre>";
            print_r($data);
            die;
            if (Auth::attempt(['email' => $data['email'], 'password' => $data['password']])) {

                // check email is activated or not (Only Work Online Server)
                /*   $userStatus = User::where('email', $data['email'])->first();
                if ($userStatus->status == 0) {
                    Auth::logout();
                    $message = "Your account is not activated yet! Please confirm your email to activate!";
                    Session::flash('error_message', $message);
                    return redirect()->back();
                }*/

                //update user cart with user id
                if (!empty(Session::get('session_id'))) {
                    $user_id = Auth::user()->id;
                    $session_id = Session::get('session_id');
                    Cart::where('session_id', $session_id)->update(['user_id' => $user_id]);
                }

                return redirect('/');
            } else {
                $message = "Invalid Username or Password";
                Session::flash('error_message', $message);
                return redirect()->back();
            }
        }
    }
}

我不知道为什么会这样？

解决方案

更新路线。有关详细信息，请查看（参考链接）https://laravel.com/docs/8.x/upgrade和https://laravel.com/docs/8.x/releases#routing-namespace-updates

像这样使用

api.php

如果不工作

Route::namespace('App\Http\Controllers\API')->group(function () {
Route::post('login', 'UsersController@loginUser');
});

然后像这样使用

use App\Http\Controllers\API\UsersController;
Route::post('login', [UsersController::class, 'loginUser']);
