How to write soft connection in laravel

Laravel is an extremely popular PHP framework that provides many convenient features and tools to develop efficient and powerful applications. One of them is soft connection. Soft links can help us reference other files or directories in the project, making the project more structured and easier to manage. In this article, we will introduce how to write soft links in Laravel.

What is a soft connection?

A soft link (Symbolic Link) is a file that allows you to link one file or directory to another file or directory. A soft link is a shortcut to a target file or directory and can save space and time.

In Laravel, soft connections are usually used for the following purposes:

• Sharing files or directories;
• Referencing public resources (such as images, audio and video);
• Deployment environment, such as deploying different environments using different configuration files.

How to create a soft connection?

In Laravel, you can use the Artisan command line tool to create soft connections. Specify the source file or directory to be linked and the target path of the link: For example, the following command will create a soft link linking the "public/images" directory in the application to the "storage/app/public/images" directory:

php artisan storage:link

After executing this command, Laravel will create a "public/storage" soft link for you, which points to the "storage/app/public" directory. Now, you can use the "public/storage" directory to access files or directories in the "storage/app/public" directory.

How to use soft connections in Laravel?

Soft connections in Laravel can be used in the following ways:

1. In templates

In Laravel views, you can use asset( ) function to reference soft links. For example, the following code will reference the "images/logo.png" file in the "public/storage" directory into the view:

<img src="{{ asset('storage/images/logo.png') }}" alt="Logo">

This will generate the following HTML code:

<img src="http://your-app.com/storage/images/logo.png" alt="Logo">

2. In the controller

In addition to the view, you can also use soft links in the controller. The following code loads audio files from the soft link directory:

public function playAudio()
{
    $audioPath = storage_path('app/public/audio/sample.mp3');

    return response()->file($audioPath);
}

This will return a response object, prompting the browser to initiate a request to "public/storage/audio/sample.mp3", and then from "storage/app/ public/audio/sample.mp3" file.

3. In the configuration file

In Laravel's configuration file, you can also use soft links. The following code demonstrates how to use soft links in a ".env" file:

APP_NAME=Laravel
APP_URL=http://your-app.com

FILESYSTEM_DRIVER=local
FILESYSTEM_CLOUD=public

LOG_CHANNEL=stack
LOG_LEVEL=debug

APP_KEY=
APP_DEBUG=true
APP_LOG=daily
APP_LOG_MAX_FILES=30
APP_LOG_LEVEL=debug

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=laravel
DB_USERNAME=root
DB_PASSWORD=

CACHE_DRIVER=file
QUEUE_CONNECTION=sync

SESSION_DRIVER=file
SESSION_LIFETIME=120

# Use a symbolic link to store public files in
PUBLIC_STORAGE_PATH=/var/www/html/your-app/storage/app/public

This will tell Laravel to use the "/var/www/html/your-app/storage/app/public" directory as "public" Soft link to the directory. This way you can store all public resources in the "storage/app/public" directory and access them from the "public" directory.

Summary

In Laravel development, soft connection is a very useful tool, which can easily map a file or directory to another place.
