使用说明

1. 环境准备

# 安装PHP依赖
composer require symfony/http-foundation doctrine/orm predis/predis
composer require elasticsearch/elasticsearch easywechat-composer/easywechat-composer
composer require firebase/php-jwt ramsey/uuid aws/aws-sdk-php
composer require endroid/qr-code intervention/image web3/web3
composer require php-ai/php-ml opencv/opencv

# 启动支持服务
docker run -d -p 3306:3306 mysql
docker run -d -p 6379:6379 redis
docker run -d -p 9200:9200 elasticsearch
docker run -d -p 8545:8545 ethereum/client-go
docker run -d -p 9000:9000 minio/minio

2. 数据库初始化

CREATE DATABASE pet_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

CREATE TABLE pets (
    id VARCHAR(36) PRIMARY KEY,
    owner_id VARCHAR(36) NOT NULL,
    name VARCHAR(100) NOT NULL,
    type ENUM('dog', 'cat', 'bird', 'other') NOT NULL,
    breed VARCHAR(100),
    birth_date DATE,
    chip_id VARCHAR(100) UNIQUE,
    created_at DATETIME NOT NULL
);

CREATE TABLE pet_health (
    id VARCHAR(36) PRIMARY KEY,
    pet_id VARCHAR(36) NOT NULL,
    health_data JSON NOT NULL,
    analysis_results JSON NOT NULL,
    recorded_at DATETIME NOT NULL,
    FOREIGN KEY (pet_id) REFERENCES pets(id)
);

CREATE TABLE pet_devices (
    id VARCHAR(36) PRIMARY KEY,
    pet_id VARCHAR(36) NOT NULL,
    type VARCHAR(50) NOT NULL,
    mac_address VARCHAR(17) UNIQUE,
    registered_at DATETIME NOT NULL,
    FOREIGN KEY (pet_id) REFERENCES pets(id)
);

3. 配置系统

创建.env.pet文件：

# 数据库配置
DB_HOST=localhost
DB_NAME=pet_db
DB_USER=pet_admin
DB_PASSWORD=secure_password_123

# Redis配置
REDIS_HOST=redis
REDIS_PORT=6379
REDIS_PASSWORD=redis_password

# 微信配置
WECHAT_APPID=wx_pet_appid
WECHAT_SECRET=wx_pet_secret
WECHAT_TOKEN=pet_token

# 区块链配置
BLOCKCHAIN_PROVIDER=http://localhost:8545
BLOCKCHAIN_CONTRACT=0xYourContractAddress
BLOCKCHAIN_ACCOUNT=0xYourAccountAddress

# 文件存储
AWS_BUCKET=pet-resources
AWS_REGION=us-east-1
AWS_CLOUD_FRONT=https://your.cloudfront.net

# OpenCV配置
OPENCV_DATA_DIR=/usr/share/opencv

4. 启动系统

# 启动PHP开发服务器
php -S 0.0.0.0:8080 -t public/

# 启动队列处理器
php bin/console messenger:consume async -vv

# 启动定时任务
php bin/console schedule:run
