php Laravel 框架之建立后台文件夹
今天研究了在Laravel框架中的控制器中添加后台的文件夹.发现了一些小的规律,拿来和大家分享一下吧.
通常情况下,我们是直接在controllers文件夹中添加我们的控制器,然后再routes.php 路由表中寻找相应的控制器和action进行处理.但是现在有个问题,如果我们的前台和后台同在一个项目中,也就是说前台和后台的控制器会在一块.当然不是没有办法进行区分.我们可以在控制器前面加上Front,Admin等标记来分别前台控制器和后台控制.
这里我给大家提供一种方法来将前后台的控制器进行分离.
首先我们在controllers文件夹中建立一个admin文件夹.
第一种方法:直接在后台建立控制器,比如AdminController.php 里面正常的写上我们的内容.
在路由表中,
Route::get('admin',[email protected]');
我们发现程序报错,说无法找到控制器AdminController.
我们打开命令行工具,进入到该项目的更目录中,也就是artisan,composer.json所在的目录中,
运行命令 composer dumpautoload 或者 composer dump-autoload
这是对自动加载进行优化.
我们运行完命令之后,进入vendor目录的composer目录中,
我们查看一下我们的autoload_classmap.php文件,发现里面多了个AdminController的一条记录.
对了,然后我们刷新一下浏览器,就能够看到该后台控制器的内容了.
但是这个有个缺点,就是每次添加新的控制器的时候都必须要运行一下这个命令才行..
还有一点需要注意的是:如果你的后台文件夹中出现了和前台相同的控制器的时候,这是的程序会报错.
提示后台和前台有个控制器名字相冲突.
这里的解决方案是在后台使用名字空间进行处理.
比如我们我的后台同样有个IndexController控制器
namespace Controllers\Admin;
class IndexController extends \BaseController{
public function index(){
}
}
?>
这里还是要注意一点了,当使用名字空间之后,我们在里面使用的所有静态类都默认是当前名字空间的类.所以有时我们需要使用use View; Use ...等之类的名字空间.
同时在路由表中我们同样要使用 Controllers\Admin\[email protected] 这样的控制器来处理请求.
好了,这就是我学到的内容,拿来和大家分享分享.
Persistence makes life valuable.
Best Wishes.

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
