Explain Blade Service Injection in Laravel.
Blade service injection is a function in Laravel for directly calling service class methods in the view layer. Through the @inject directive, such as @inject('variable name','namespace\class name'), you can get the service instance in the view and call its public methods. It is suitable for scenarios such as obtaining global configuration, displaying cache statistics, displaying widget content, verifying permissions or status. When using it, you should pay attention to keeping the view logic concise, ensuring that the service class has bound containers, avoiding repeated calls to affect performance, and prioritizing unified management of data through components, instructions or view composer.

Protecting against Mass Assignment in Laravel.
MassAssignment refers to the assignment of multiple attributes to the model at one time by requesting, which may bring security risks. Prevention methods include: 1. Use the $fillable whitelist to explicitly allow fields to be filled, such as name, email, password; 2. Use the $guarded blacklist to exclude unfilled sensitive fields, such as is_admin; 3. Avoid using $request->all() directly. It is recommended to verify and filter out the required fields first; 4. Use the form request verification to enhance security; 5. Simulate illegal field submission during testing to ensure security. Reasonable use of whitelists or blacklists and cooperation with data verification can effectively prevent such hidden dangers.

Explain Laravel Passport vs Sanctum.
Sanctum is lighter and suitable for SPA or mobile, while Passport is more powerful and suitable for OAuth2 services. 1. Passport supports third-party authorization for open API scenarios such as GitHub login, and Sanctum is suitable for front-end separation or mobile-side self-use APIs. 2. Passport is complex to install and configure client ID/Secret and token policies. Sanctum is simple to configure and publish migration and modify guard drivers. 3. Passport uses JWT to encrypt tokens without checking the library and verifying it. Sanctum plaintext storage tokens requires each query, but the management is more intuitive. 4. Passport is naturally stateless and suitable for cross-domain deployment, Sanc

Handling HTTP Requests and Responses in Laravel.
The core of handling HTTP requests and responses in Laravel is to master the acquisition of request data, response return and file upload. 1. When receiving request data, you can inject the Request instance through type prompts and use input() or magic methods to obtain fields, and combine validate() or form request classes for verification; 2. Return response supports strings, views, JSON, responses with status codes and headers and redirect operations; 3. When processing file uploads, you need to use the file() method and store() to store files.

Difference between Eloquent ORM and the Query Builder in Laravel.
The main difference between EloquentORM and QueryBuilder in Laravel is the operation method and applicable scenarios. 1. Eloquent is based on the model and provides object-oriented data interaction methods, suitable for processing model logic and relationships; QueryBuilder directly operates database tables, suitable for quickly obtaining or manipulating data. 2.QueryBuilder has higher performance because it does not instantiate a complete model object and is suitable for large data volumes or complex connections; Eloquent is suitable for scenarios where model functions are required. 3.Eloquent supports defining and using model relationships (such as hasMany, belongsTo) and provides lazy loading functions; QueryBuil

How to perform Request Validation in Laravel?
There are two main methods for request verification in Laravel: controller verification and form request classes. 1. The validate() method in the controller is suitable for simple scenarios, directly passing in rules and automatically returning errors; 2. The FormRequest class is suitable for complex or reusable scenarios, creating classes through Artisan and defining rules in rules() to achieve code decoupling and reusing; 3. The error prompts can be customized through messages() to improve user experience; 4. Defining field alias through attributes() to make the error message more friendly; the two methods have their advantages and disadvantages, and the appropriate solution should be selected according to project needs.
