使用 Laravel Notifynder 扩展轻松实现 Laravel 应用的消息通知功能
1、简介
Notifynder 以简单的方式提供了强大的消息通知管理功能:其提供的完整API可用于对消息通知的各种处理,比如存储、检索以及组织处理成百上千条通知的代码库。有了Notifynder,你可以在几分钟内在你的Laravel项目中“启用”消息通知功能。
目前支持的数据库包括MySQL、Postgres和SQLite。
2、安装
使用Composer安装该扩展:
composer require fenos/notifynder
然后到 config/app.php 中注册服务提供者:
Fenos\Notifynder\NotifynderServiceProvider::class,
以及门面:
'Notifynder' => Fenos\Notifynder\Facades\Notifynder::class,
发布该扩展包的配置文件到 config 目录:
php artisan vendor:publish --provider="Fenos\Notifynder\NotifynderServiceProvider"
最后运行数据库迁移生成相应数据表:
php artisan migrate
3、快速上手
创建分类
在开始使用Notifynder之前,我们需要简单了解“分类”这一术语在Notifynder中的职责,分类是消息通知的主体,通过唯一的名称来区分,并且拥有对应的通知文本,每个通知都要绑定到一个分类上,以便于管理和维护。
首先我们使用Notifynder提供的Artisan命令来创建一个分类 :
php artisan notifynder:create:category "user.following" "{from.username} started to follow you"
这会在数据库 notification_categories 表中创建一条新纪录:
功能实现
接下来确定要被通知的模型,通常我们选择 User 模型,这个被选择的模型类要使用 Notifable Trait:
use Fenos\Notifynder\Notifable;class User extends Model{ use Notifable;}
这样我们的模型实体就可以处理消息通知了:
$user = User::find(1);$user->getNotifications($limit = null, $paginate = null, $order = 'desc');$user->getNotificationsNotRead($limit = null, $paginate = null, $order = 'desc');$user->getLastNotification();$user->countNotificationsNotRead($category = null);$user->readAllNotifications();
注:如果你不想使用 Notifable Trait,也可以直接使用 Notifynder 门面上的对应方法。
4、发送通知
发送通知非常简单:
$from_user_id = 1;$to_user_id = 2;Notifynder::category('user.following') ->from($from_user_id) ->to($to_user_id) ->url('http://laravelacademy.org/notifications') ->send();
发送通知后我们来检索通知:
$userNotified = User::find($to_user_id);dd($userNotified->getNotificationsNotRead());
还可以一次发送多个通知,这里我们给多个用户发送通知:
// It send a notification to all the userstry { $this->notifynder->loop($users, function(NotifynderBuilder $builder, $user) { $builder->category('sayhello') ->from(1) ->to($user->id) ->url('http://localhost') ->extra(compact('period_day')); })->send();} catch (EntityNotIterableException $e) {} catch (IterableIsEmptyException $e) {}

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
