英文:

laravel Method Illuminate\\Validation\\Validator::false does not exist

问题

I can help you with the translation:

（我是新手使用 Laravel）
Postman API 测试一直出现以下错误：
```plaintext
"status": false,
"message": "Illuminate\\Validation\\Validator 类中不存在 false 方法。"

用于注册新用户测试的函数：

<?php

namespace App\Http\Controllers\Api;

use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Support\Carbon;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;

class UserController extends Controller
{
    /**
     * 创建用户
     * @param Request $request
     * @return Response
     */

    public function createUser(Request $request)
    {
        try {

             $validateUser = Validator::make($request->all(),
            [      
                'name' => 'required',
                'email' => 'required|email|unique:users,email',
                'password' => 'required'
            ]);

            if($validateUser->fails()){
                return response()->json([
                    'status' => false,
                    'message' => '验证错误',
                    'errors' => $validateUser->errors()
                ], 401);
            }

          $user = User::create([
            'name' => $request->name,
            'email' => $request->email,
            'password' => $request->password
          ]);
           
            return response()->json([
                'status' => true,
                'message' => '用户创建成功',
                'token' => $userInfo
            ], 200);

        } catch(\Throwable $th){
            return response()->json([
                'status' => false,
                'message' => $th->getMessage()
            ], 401);
        }
    }

}

请问有人可以帮我吗？我使用了 use Validator; 但仍然收到相同的错误消息！

使用`$validateUser->fails()`代替`$validateUser->false()`。

Use `$validateUser-&gt;fails()` instead of `$validateUser-&gt;false()`

I believe you are looking for the translation of the provided code snippets. Here they are:
```php
我相信你正在寻找来自Laravel文档中的失败，而不是false：
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class PostController extends Controller
{
/**
* 存储新博客文章。
*/
public function store(Request $request): RedirectResponse
{
$validator = Validator::make($request->all(), [
'title' => 'required|unique:posts|max:255',
'body' => 'required',
]);
if ($validator->fails()) {
return redirect('post/create')
->withErrors($validator)
->withInput();
}
}
}

所以你的代码将是：

namespace App\Http\Controllers\Api;

use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Support\Carbon;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;

class UserController extends Controller
{
    /**
     * 创建用户
     * @param Request $request
     * @return Response
     */

    public function createUser(Request $request)
    {
        try {

             $validateUser = Validator::make($request->all(),
            [      
                'name'=> 'required',
                'email' => 'required|email|unique:users,email',
                'password' => 'required'
            ]);

            if($validateUser->fails()){
                return response()->json([
                    'status' => false,
                    'message' => '验证错误',
                    'errors' => $validateUser->errors()
                ], 401);
            }

          $user = User::create([
            'name' => $request->name,
            'message' => $request->email,
            'password' => $request->password
          ]);
           
            return response()->json([
                'status' => true,
                'message' => '用户创建成功',
                'token' => $userInfo
            ], 200);

        } catch(\Throwable $th){
            return response()->json([
                'status' => false,
                'message' => $th->getMessage()
            ], 401);
        }
    }
}

I believe you are looking for fails, not false, from the Laravel documentation:
```php
&lt;?php
namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\RedirectResponse;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
class PostController extends Controller
{
/**
* Store a new blog post.
*/
public function store(Request $request): RedirectResponse
{
$validator = Validator::make($request-&gt;all(), [
&#39;title&#39; =&gt; &#39;required|unique:posts|max:255&#39;,
&#39;body&#39; =&gt; &#39;required&#39;,
]);
if ($validator-&gt;fails()) {
return redirect(&#39;post/create&#39;)
-&gt;withErrors($validator)
-&gt;withInput();
}

so your code is going to be:

<?php

namespace App\Http\Controllers\Api;

use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Support\Carbon;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\ِAuth;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;


class UserController extends Controller
{
    /**
     * Create User
     * @param Request $request
     * @return Response
     */

    public function createUser(Request $request)
    {
        try {

             $validateUser = Validator::make($request->all(),
            [      
                'name'=> 'required',
                'email' => 'required|email|unique:users,email',
                'password' => 'required'
            ]);

            if($validateUser->fails()){
                return response()->json([
                    'status' => false,
                    'message' => 'validation error',
                    'errors' => $validateUser->errors()
                ], 401);
            }

          $user = User::ceate([
            'name' => $request->name,
            'message' => $request->email,
            'password' => $request->password
          ]);
           
            return response()->json([
                'status' => true,
                'message' => 'User Created Succssfully',
                'token' => $userInfo
            ], 200);

        } catch(\Throwable $th){
            return response()->json([
                'status' => false,
                'message' => $th->getMessage()
            ], 401);
        }
    }

}
