Question

我的控制器代码：

public static async Task AuthenticationFailed(this AuthenticationFailedContext context)
{
    ILoggerFactory loggerFactory = context.HttpContext.RequestServices.GetService<ILoggerFactory>();
    ILogger logger = loggerFactory.CreateLogger(nameof(JwtBearerExtensions));

    string refreshToken = context.HttpContext.Request.Cookies[Defaults.RefreshTokenCookie];

    if (string.IsNullOrEmpty(refreshToken))
    {
        logger.LogWarning("No refresh token supplied with invalid JWT, Cookies are {0}", string.Join(", ", context.HttpContext.Request.Cookies.Keys));
        return;
    }

    logger.LogInformation("Processing refresh token '{0}'.", refreshToken);

    IConfiguration configuration = context.HttpContext.RequestServices.GetService<IConfiguration>();
    IUserService userService = context.HttpContext.RequestServices.GetService<IUserService>();
    ITokenHandler handler = context.HttpContext.RequestServices.GetService<ITokenHandler>();

    long? userId = await handler.ValidateRefreshToken(refreshToken);

    if (userId.HasValue)
    {
        User user = await userService.GetUserAsync(userId.Value);
        refreshToken = await handler.GenerateRefreshToken(userId.Value);
        string jwtToken = BuildJwtToken(user, configuration);
        context.HttpContext.Response.AddBearerAuthorization(jwtToken);
        context.HttpContext.Response.AddRefreshTokenCookie(refreshToken);
        context.Principal = new ClaimsPrincipal(BuildClaimsIdentity(user));
        context.Success();
    }
}

Response

我的请求参数：

public function addGroup(Request $request)
{
    $validator = UserValidations::validateGroups($request->all());

    if($validator->fails()) {
        return response(['status' => false, 'message' => 'Validation Errors', 'errors' => $validator->errors()->all()], 500);
    }

    try {

        $request->request->add(['created_by' => Auth::user()->id]);
        $group = $this->group->create($request->only($this->group->getModel()->fillable));

        if(!empty($request->get('group_members')))
        {
            $groupMembers = Group::where('id', $group->id);
            $groupMembers->users()->attach($request->get('group_members'));
        }


        return response(['status' => true, 'message' => 'Group added', 'data' => $group], 500);

    } catch (\Exception $ex) {
        return response(['status' => false, 'message' => 'Validation Errors', 'errors' => $ex->getMessage()], 500);
    }
}

我想用组成员（用户）分配组名并创建组名，但是我遇到了public function users() { return $this->belongsToMany('App\Models\Users\User', 'group_members'); }

错误

我在哪里做错了？非常感谢您的帮助！

您必须以这种方式获取组：

$groupMembers = Group::where('id', $group->id)->first();

要能够将Users附加到Group，首先需要使用first()获取实例。您无法在attach()上致电Query\Builder

“使用laravel调用未定义的方法Illuminate \\ Database \\ Query \\ Builder :: users（）
