Laravel 在null上调用成员函数createToken（）

我是laravel api和laravel passport的新手，我知道这是一个老问题，但没有答案帮助我。我正在使用laravel passport进行api 注册，登录工作正常，但注销和错误

这是我的注册代码

 public function register (Request $request) {
    $validator = Validator::make($request->all(), [
            'UserName' => 'required|string|max:255',
            'UserFullName' => 'string|max:255',
            'UserEmail' => 'required|string|email|max:255|unique:users',
            'UserPhone' => 'required|string|max:255|unique:users',
            'Password' => 'required|string|min:6|confirmed',
        ]);
        if ($validator->fails())
        {
            return response(['errors'=>$validator->errors()->all()], 422);
        }
        if ($request['UserPhone']==Null) { // will check for empty string, null values, see php.net about it
            $request['UserPhone'] = NULL;
        }
        $request['Password']=Hash::make($request['Password']);
        $request['remember_token'] = Str::random(10);
        $request['UserType'] = $request['UserType'] ? $request['UserType']  : 1;
        //return response($request, 200);
        $user = User::create($request->toArray());
        $token = $user->createToken('Laravel Password Grant Client')->accessToken;
        //return response($token, 200);
        $response['data']= $user;
        $response['data']['token'] = $token;
        return response($response, 200);
    }

    public function login (Request $request) {
        $validator = Validator::make($request->all(), [
            'UserEmail' => 'required|string|email|max:255',
            'Password' => 'required|string|min:6',
        ]);
        if ($validator->fails())
        {
            return response(['errors'=>$validator->errors()->all()], 422);
        }
        $user = User::where('UserEmail', $request->UserEmail)->first();
        if ($user) {
            if (Hash::check($request->Password, $user->Password)) {
                $token = $user->createToken('Laravel Password Grant Client')->accessToken;
                $response['data']= $user;
                $response['data']['token'] = $token;
                return response($response, 200);
            } else {
                $response = ["message" => "Password mismatch"];
                return response($response, 422);
            }

            $response = ["message" =>'User does not exist'];
            return response($response, 422);
        }
    }

public function logout (Request $request) {
        //return $request->Authorization;
        $token = $request->user()->token();
        //return $token;
        $token->revoke();
        $response = ['message' => 'You have been successfully logged out!'];
        return response($response, 200);
    }

问题是授权，似乎所有带有授权头的post api都应该通过身份验证检查，我将注销路径移动到中间件中

Route::group(['middleware'=>['auth:api']],function(){
Route::get('/companies', 'CompanyController@index')->name('companies');
});

但是我不确定为什么它不能与if（Auth:check）一起工作{ …进一步撤销代码 ...

}

您可以使用此路由组，它将正常工作

Route::group(['middleware'=>['auth:api']],function(){
    Route::post('/logout', 'Api\AuthController@logout');    
});

看起来您的注销API不是在调用注销函数，而是在调用登录/注册函数。检查是否调用了注销函数，如果是，则检查函数执行到哪一点时没有任何错误。因此，您可以找到抛出错误的确切行谢谢您的帮助。我不确定您所说的注销功能是什么意思，如果我没有记错您所说的laravel Auth:：logout，我想这是用于web会话的。谢谢你。
