Transitioning: Reasons for a rapid, systematic transition to Go engineering:
To improve CRUD operations.
To gain experience with self-developed frameworks.
For colleagues aiming to deepen technical expertise, specializing and refining requirements.
To advance engineering practices, developing good coding standards and management capabilities.

The Importance of Engineering

Expectations for Senior Developers:
Good code standards.
Deep understanding of underlying principles.
Familiarity with architecture.
Familiarity with K8s basic architecture.
Expanding knowledge breadth and depth, and a standardized development system.

Four Major Stages:
Go language fundamentals.
Microservice development (e-commerce project practical experience).
Self-developed microservices.
Self-developed, then re...

grpc grpc grpc-go grpc seamlessly integrates protobuf protobuf. For those of you accustomed to using JSON and XML data storage formats, I believe most have never heard of Protocol Buffer. Protocol Buffer is actually a lightweight & efficient structured data storage format developed by Google, and its performance is truly much, much stronger than JSON and XML! protobuf…

For microservice development, create a microservice project where all project microservices will reside. Create `joyshop_srv`. We need to create user login and registration services, so we will create another directory `user_srv` under the project directory, along with `user_srv/global` (for global object creation and initialization), `user_srv/handler` (for business logic code), `user_srv/model` (for user-related models), `user_srv/pro...`

Project Structure Description: The user-web module is the user service Web layer module within the joyshop_api project, responsible for handling user-related HTTP requests, parameter validation, business routing, and calling backend interfaces. Below is the directory structure description: user-web/ ├── api/ # Controller layer, defines business interface processing logic ├── config/ # Configuration module, contains system configuration structs and reading logic ...

Orders and Shopping Cart
First, copy the service code framework of 'srv' from the inventory service, then find and replace the corresponding name (order_srv).

Fundamentals of Encryption Technology
Symmetric Encryption
Principle:
Uses the same key for encryption and decryption.
Like a single key that can both lock and unlock a door.
Fast encryption speed, suitable for large data transfers.
Use cases:
Local file encryption
Database content encryption
Content encryption during large data transfers
Fast communication between internal systems...

Install Elasticsearch (understand as a database) and Kibana (understand as a connection tool). The versions of ES and Kibana (port 5601) must be consistent.
