Preventing XSS attacks in Laravel.
To prevent XSS attacks, you must always use double braces to output content, verify and filter user input, and use CSP to enhance protection. Use {{}} to automatically escape variables in Blade templates to avoid using {!!!!!!} unless the content is trustworthy; the backend needs to verify the user input format and clean up HTML tags, and you can use strip_tags or third-party libraries; finally configure the CSP policy through HTTP headers to limit the script source and prevent inline script execution, thus forming a multi-layer defense system.

Explain Model Observers in Laravel.

It can centrally manage model events such as operations during creation, update, and deletion, keeping the code neat. For example, send a welcome email after the user is created. The steps to use include: 1. Use the Artisan command to generate the Observer class; 2. Bind the Observer to the model in the service provider; 3. Define the method of handling events in the Observer. Applicable scenarios include data cleaning, logging, notification triggering, cache management, etc. When using it, you should pay attention to avoid time-consuming operations, listen to events on demand, and ensure correct binding and testing.

Explain Laravel Authentication mechanisms.
Laravel's certification mechanism is flexible and powerful, which can not only meet common needs, but also supports deep customization. 1. The default authentication is based on Session, and the login, logout and status check are handled through the Auth facade. The user model is App\Models\User, and the configuration is located in config/auth.php; 2. Custom logic can be distinguished by modifying controller methods (such as attemptLogin), writing middleware, or using multiple Guards to distinguish different authentication scenarios; 3. API authentication is recommended for Sanctum for SPA or mobile terminals, Passport is suitable for complex scenarios requiring OAuth2; 4. Notes include running migration files, setting the validity period of the token, and correctly configuring it.

How to create API versioning in Laravel routes?
The core method of implementing API versioning in Laravel is to distinguish versions by routing grouping and controller directory structure. 1. Use routing packets to set v1 and v2 prefixes to point to different versions of controllers; 2. Press V1 and V2 to organize the controller directory under app/Http/Controllers/Api to keep the structure clear; 3. You can use middleware to parse the Accept request header to achieve version control, but the URL explicitly specifies the version more intuitively; at the same time, you should pay attention to keeping the version independent, updating the document synchronously, and prompting the current version in the response header.

What are migrations in Laravel and how to use them?
Laravel migration is a database version control tool that uses code to manage database structure changes. 1. Migrate Git like "Database" to record operations such as creating tables, adding columns, etc., to facilitate team collaboration and rollback. 2. Use the Artisan command to create a migration file, such as phpartisanmake:migrationcreate_users_table, and you can specify the operation type through --create or --table. 3. In the migration file, the up() method defines structure changes, and down() is used for rollback. 4. Use phpartisanmigrate to perform migration, and you can use --path to specify a specific file. 5. Roll back the last migration with mig

Explain Laravel Database Migrations.
Database migration is a version control tool in Laravel for managing database structure changes. It allows the use of PHP code to define and synchronize table structures to avoid manual operation of the database. 1.

Use the Schema builder and Blueprint class to create tables and fields, and support common types and constraints; 3. Common Artisan commands include migrate run, rollback rollback, reset reset, refresh refresh, and make:migration to generate new files; 4.

What is the N 1 query problem and how to solve it in Laravel?
The N 1 query problem refers to the execution of additional query on each piece of data after obtaining a set of data, resulting in a large number of repeated requests. For example, after taking out 100 article records, each article will query the author information separately, and a total of 101 queries will be performed. Discovery methods include using the LaravelDebugbar plugin, enabling query logs to observe duplicate SQL, and using IDE or static analysis tools to detect unpreloaded relationships. The solution is to use EagerLoading to preload, such as Post::with('author')->get(), which can load the associated data at one time to reduce the number of queries; supports multi-layer nesting with('author.socialMedia'); can also load l dynamically
