Magento 使用 geoip2 插件做用户IP定位功能

一. 安装 geoip2 库，并检查ip

第一步：安装 geoip2 库

composer require geoip2/geoip2:~2.0

 

第二步：下载 GeoLite2 数据库
需要注册账户，注册成功后就可以直接下载 GeoLite2 数据库
第三步：调用 ip 检测方法

$reader = new Reader('/var/geoip/GeoLite2-Country.mmdb'); //替换成自己的数据库文件路径
$record = $reader->city('128.101.101.101');
print($record->country->isoCode);

 

 

二. 更新 geoip2 数据库

在 Windows 系统上开发 Shopify 插件（通常称为 Shopify Apps）是完全可行的。Shopify 应用可以是独立的网络应用程序，它与 Shopify 店铺通过 Shopify API 交互。以下是开发 Shopify 应用的完整流程：

1. 环境设置

设置开发环境

首先，确保你的 Windows 机器安装有以下工具：
- 文本编辑器或IDE（如 Visual Studio Code, Sublime Text, JetBrains PhpStorm）
- Ruby（Shopify CLI 需要 Ruby 来运行）
- Node.js（用于 Shopify Node.js 或 React 应用）
- Git（代码版本控制）
- Shopify CLI（命令行工具，用于创建和管理 Shopify 应用）

你可以从 Shopify 的官方网站下载并安装 Shopify CLI。

安装 Shopify CLI

在 Windows 上安装 Shopify CLI，通常可以通过 RubyGems 安装：

gem install shopify-cli

 

2. 注册 Shopify 开发者账号

- 访问 Shopify Partners 网站并注册一个开发者账号。
- 创建一个 Partners 账户后，你可以创建开发商店，用于测试和开发应用。

3. 创建新的 Shopify 应用

- 在 Shopify Partner Dashboard 中创建一个新的应用。
- 设置应用的配置，包括应用名称、URL、回调地址等。

4. 开发应用

使用 Shopify CLI 创建应用

在命令行中运行以下命令来创建一个新的 Shopify 应用（支持 Node.js 和 Ruby on Rails）：

shopify app create node

或

shopify app create rails

 

这些命令将生成一个应用的基础架构，包括用于与 Shopify API 交互的一些初始代码。

开发功能

根据你的应用需求，你可能需要开发以下功能：
- 认证和授权（使用 OAuth）
- 与 Shopify API 交互
- 前端界面（如果是嵌入式应用，使用 Polaris 或其他前端框架）
- Webhooks 处理
- 定期任务处理

5. 测试应用

- 使用你的开发商店测试应用功能。
- 确保所有功能在实际场景下都能正常工作。

6. 部署应用

- 将应用部署到生产环境。通常可以使用云服务平台，如 Heroku、AWS、Azure 等。
- 更新应用的配置，确保所有生产环境的 URL 和回调地址都是正确的。

7. 提交应用审核

- 如果你打算将应用发布到 Shopify App Store，则需要提交给 Shopify 进行审核。
- 遵循 Shopify 的应用审核指南和最佳实践，确保应用符合所有要求。

8. 发布应用

- 审核通过后，你的应用就可以在 Shopify App Store 上架了。
- 根据用户反馈和需求，继续维护和更新应用。

使用 Windows 开发 Shopify 应用完全可行，重要的是遵循开发和部署的最佳实践，并确保提供高质量的用户体验。

前几天逛github，无意中发现了国外大神（magenx）的一键部署命令，然后做了测试，第一次部署因为没细看，导致中途出了很多问题；后面认真理解了部署步骤命令跟着操作后很顺利，总体而言还是比较不错，推荐一下；

环境：debian11/unbuntu20.04（貌似也支持centos，但是我没有实测）；

我的环境是ubuntu20.04，空白环境；

话不多说，直接上命令；

curl -Lo magenx.sh https://magenx.sh && bash magenx.sh 执行操作后，就开始跑了，会自动安装环境所需，自动更改SSH端口，请留意窗口展示,（为啥我不能上传图片） 执行命令过程中每个环境所需的每个软件安装都需要确认，包括magento版本选择等； lemp,magento,database,install,config,执行完成后根据自己的需求可以继续安装webmin和firewell; 最后执行certbot certonly --agree-tos --no-eff-email --email {EMAIL} --webroot -w /home/{USER}/public_html/pub 生成ssl;并修改相关的配置文件

• /etc/nginx/nginx.conf
• /etc/nginx/sites-available/{DOMAIN_NAME}.conf
• /etc/nginx/conf_m2/varnish_proxy.conf
• 然后就可以上线了

新人报道magento，多多关照

magento的代码高度模块化，阅读时一般分模块阅读。在阅读某个模块的代码的时候可以把代码大致分成三类：

1. 实现/继承了其他模块的接口/类的代码

2. 本模块对外定义的接口/类

3. 本模块内部使用的接口/类

对于第1类代码，需要在熟悉关联模块的代码的基础之上再阅读（或者说在读之前，先要阅读关联模块的代码。）。这类代码一般处于和关联模块名同名的文件夹下。

对于第2类代码，模块可能会定义多个类和接口，这些类与接口之间的组合关系可能会用到行为型模式，比如：策略模式、状态模式、观察者模式等等。（通常都只是简单组合，行为型模式本质就是低耦合，只是组合之外符合特定行为定义而已。）

对于第3类代码，模块之所以定义这些接口/类是为第2类代码服务的，这类代码定义的接口/类与第1类代码定义的接口/类要么是继承关系，要么是组合关系。如果是组合关系，通常会用到结构型模式，比如：桥接模式、组合模式、装饰模式、代理模式等等。这类代码一般处于模块子目录文件夹里。（结构型模式本质是高内聚，涉及的类都将实现同一个接口）

看magento自带一套restapi，看了作者写的api章节要用这个restapi要先在后台建立一个用户，但是我们网站上都已经有很多用户了，怎么直接用网站上现有的用户？

本文介绍两种方式:

1. 本地手动运行测试
2. push到Github时利用Github Actions 自动测试

 

1. 本地手动测试（本地需安装php 8.1 运行环境）

#切换到项目根目录运行以下命令

! find . -not \( -path ./.phpstorm.meta.php -prune \) -type f -name "*.php" -exec php -d error_reporting=32767 -l {} \; 2>&1 1> /dev/null | grep "^"

效果如图：

2. Github Actions 自动测试

1. 在项目根目录新建.github/workflows/文件夹
2. 在.github/workflows/下新建php-syntax-check.yml并添加以下代码

   name: "PHP Syntax Check"
   on:
     push:
     pull_request:
   
   jobs:
     php_syntax_check:
       name: PHP Syntax ${{ matrix.php-versions }} Check
       runs-on: ${{ matrix.operating-system }}
       needs: php_syntax
       strategy:
         max-parallel: 1
         fail-fast: false
         matrix:
           operating-system: [ubuntu-latest]
           php-versions: ["8.1"]
       steps:
         - uses: actions/checkout@v1
         - name: Setup PHP
           uses: shivammathur/setup-php@master
           with:
             php-version: ${{ matrix.php-versions }}
             extension-csv: mbstring #optional, setup extensions
             ini-values-csv: post_max_size=256M, short_open_tag=On #optional, setup php.ini configuration
             coverage: none #optional, setup coverage driver
             pecl: true #optional, setup PECL
         - name: Check PHP Version
           run: php -v
         - name: Check .php files
           continue-on-error: true
           run: '! find . -not \( -path ./.phpstorm.meta.php -prune \) -type f -name "*.php" -exec php -d error_reporting=32767 -l {} \; 2>&1 1> /dev/null | grep "^"'

一. vps系统：Linux CentOS 7.7.1908 64bit

二. yum -y update 更新一下centos系统

三. oneinstack自动安装，生成安装命令如下链接：https://oneinstack.com/auto/
【 备注：apache2.4, Mariadb10.4, php7.4(默认）, php8.0（第二安装）, 勾选php扩展（fileinfo, redis, memcached, swoole), 下面再勾选：node.js(根据以后需要打勾）, .... iptables 】

四. 修改默认的php.ini的配置文件并保存
vi /usr/local/php/etc/php.ini
找到下面这些项进行修改 ( vi下面按esc, 然后： /查找的字符）
1. memory_limit = 1024M
2. max_execution_time = 18000
3. max_input_time = 1800
4. zlib.output_compression = on
5. 找到这项 disable_functions=... 删除3个禁止的函数：exec, proc_open, proc_get_status

五. 重启php-fpm, httpd
service php-fpm restart
service httpd restart

六. 安装elasticsearch (magento必装插件）
【 首先安装 JDK 环境 】
1. 本机是否已经安装，ElasticSearch 最低支持 jdk 1.7
yum list installed | grep java

2. 查看 yum 库中的 java 安装包
yum list java*

3. 安装 java-1.8.0
yum install -y java-1.8.0-openjdk

4. 安装完成后查看 java 版本
java -version (出现以下信息则安装成功）
//openjdk version "1.8.0_212"
//OpenJDK Runtime Environment (build 1.8.0_212-b04)
//OpenJDK 64-Bit Server VM (build 25.212-b04, mixed mode)
------------------------------------------------------------
【 安装 elasticsearch（当前为 7.2）】

5. 下载并安装公共签名密钥
rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch

6. 创建 yum 源文件
vim /etc/yum.repos.d/elasticsearch.repo

把下面这段粘上去进行保存即可
[elasticsearch-7.x]
name=Elasticsearch repository for 7.x packages
baseurl=https://artifacts.elastic.co/packages/7.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

7. 安装 elasticsearch
yum install -y elasticsearch

8. 配置 elasticsearch

8.1 配置文件都在 /etc/elasticsearch/ 目录下
vim /etc/elasticsearch/elasticsearch.yml

**集群名称
cluster.name: jhxxb
节点名称
node.name: node-1
数据文件与日志文件存放目录
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
网络设置
network.host: 0.0.0.0 //改为127.0.0.1 或者 localhost
http.port: 9200
集群设置
cluster.initial_master_nodes: ["node-1"]**

8.2 修改配置中目录的用户与用户组，不然无法启动
chown -R elasticsearch:elasticsearch /var/lib/elasticsearch
chown -R elasticsearch:elasticsearch /var/log/elasticsearch

【 启动 elasticsearch 】

9. 启动
systemctl start elasticsearch.service

10. 开机自启
systemctl enable elasticsearch.service

11. 查看状态
systemctl status elasticsearch.service

七. 创建新站点信息
./vhost.sh
./pureftpd_vhost.sh

八. 创建新站点数据库
通过phpMyAdmin完成建库

九. 为数据库添加用户权限
mysql -uroot -p
提示输入密码进入
执行：（换成你自己的数据库名，用户，密码）
MySQL [(none)]> grant all privileges on db_name.* to db_user@'%' identified by 'db_pass';
MySQL [(none)]> flush privileges;
MySQL [(none)]> exit;

十. 将magento下载的2.4.3数据样本上传到站点目录下面进行解压
tar -zxvf magento*******.tar.gz

十一. 给目录相应的用户组及权限, 根目录下面执行
chown -R www *
chown -R :www *

十二. 进入站点目录执行以下安装命令：
php bin/magento setup:install --base-url=https://www.域名.com/ --db-host=127.0.0.1 --db-name=数据库名 --db-user=数据库用户 --db-password=数据库密码 --admin-firstname=Admin --admin-lastname=User --admin-user=admin --admin-password=后台登陆密码 --language=en_US --currency=USD --timezone=America/Chicago --use-rewrites=1 --backend-frontname=后台名称 --search-engine=elasticsearch7 --elasticsearch-host=localhost --elasticsearch-port=9200

十三. 关闭双重验证模块
php bin/magento module:disable Magento_TwoFactorAuth

十四. 上传useful_commands.sh(由群里的大佬提示）文件到根目录下面执行一下
sh useful_commands.sh

sh文件内容如下：
find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 755 {} \;
find ./var -type d -exec chmod 777 {} \;
find ./pub/media -type d -exec chmod 777 {} \;
find ./pub/static -type d -exec chmod 777 {} \;
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento indexer:reindex
php bin/magento cache:clean
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

十五, 登陆后台 大功告成。

events事件在magento2里是核心内容，用于监听某个事件来执行相关操作。类似于jquery的on或者wp的钩子hook。

在修改核心代码逻辑时非常方便 也不会产生模块间的冲突。

 

events监听例子

比如监听下单成功后事件：

假设你的插件是 Vendor/Extension

1，在events.xml里定义

在 app/code/Vendor/Extension/etc/ 创建events.xml文件。

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="sales_order_place_after">
        <observer name="place_order_after" instance="Vendor\Extension\Observer\Orderplaceafter"/>
    </event>
</config>

2，实现处理逻辑方法

在app/code/Vendor/Extension/Observer/里创建Orderplaceafter.php

<?php

namespace Vendor\Extension\Observer;

use Magento\Framework\Event\ObserverInterface;
use Psr\Log\LoggerInterface;

class Orderplaceafter implements ObserverInterface
{
    protected $logger;

    public function __construct(LoggerInterface $logger)
    {
        $this->logger = $logger;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        try {
            $order = $observer->getEvent()->getOrder();
            //在这里做你想做的事
        } catch (\Exception $e) {
            $this->logger->info($e->getMessage());
        }
    }
}

 

 

常用的events事件如下

具体event代表什么意思，需要你自己去分析，等用到的时候就会懂了。

 

文件位置	Event事件名
vendor/magento/module-backend/Block/System/Store/Edit/AbstractForm.php	adminhtml_store_edit_form_prepare_form
vendor/magento/module-backend/Block/Template.php	adminhtml_block_html_before
vendor/magento/module-backend/Block/Widget/Grid.php	backend_block_widget_grid_prepare_grid_before
vendor/magento/module-backend/Console/Command/CacheCleanCommand.php	adminhtml_cache_flush_system
vendor/magento/module-backend/Console/Command/CacheFlushCommand.php	adminhtml_cache_flush_all
