基于 yiisoft/yii2-app-advanced，在 GitHub 上新建仓库 yii2-app-advanced，UUID 的实现 (十)
1、在 Github 上搜索 yii2 uuid，选择 wartron/yii2-uuid，如图1
2、基于 Composer 安装，报错
composer require wartron/yii2-uuid "*"
./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - The requested package wartron/yii2-uuid * is satisfiable by wartron/yii2-uuid[dev-master] but these conflict with your requirements or minimum-stability. Installation failed, reverting ./composer.json to its original content.
3、基于 Composer 安装，安装成功，如图2
composer require wartron/yii2-uuid "dev-master"
./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Package operations: 3 installs, 0 updates, 0 removals - Installing paragonie/random_compat (v2.0.17): Downloading (100%) - Installing ramsey/uuid (2.9.0): Downloading (100%) - Installing wartron/yii2-uuid (dev-master 2202443): Cloning 2202443ac7 from cache paragonie/random_compat suggests installing ext-libsodium (Provides a modern crypto API that can be used to generate ran dom bytes.) ramsey/uuid suggests installing moontoast/math (Support for converting UUID to 128-bit integer (in string form).) ramsey/uuid suggests installing doctrine/dbal (Allow the use of a UUID as doctrine field type.) Writing lock file Generating autoload files
4、新建数据库迁移，添加 uuid 字段到 page 模型
.\yii migrate/create add_uuid_to_page
5、编辑数据库迁移文件，\console\migrations\m180807_032326_add_uuid_to_page.php，设置 uuid 为唯一索引
<?php
use yii\db\Migration;
/**
* Class m180807_032326_add_uuid_to_page
*/
class m180807_032326_add_uuid_to_page extends Migration
{
/**
* {@inheritdoc}
*/
public function safeUp()
{
$this->addColumn('{{%page}}', 'uuid', $this->string(64)->notNull()->comment('通用唯一识别码')->after('id'));
$this->createIndex('uc_uuid', '{{%page}}', 'uuid', $unique = true);
}
/**
* {@inheritdoc}
*/
public function safeDown()
{
$this->dropColumn('{{%page}}', 'uuid');
}
/*
// Use up()/down() to run migration code without a transaction.
public function up()
{
}
public function down()
{
echo "m180807_032326_add_uuid_to_page cannot be reverted.\n";
return false;
}
*/
}
6、执行数据库迁移，查看表结构，基于 Gii 重新生成模型文件，如图3
.\yii migrate
7、附加行为 wartron\yii2uuid\behaviors\UUIDBehavior，编辑 \common\logics\Page.php
<?php
namespace common\logics;
use Yii;
use yii\behaviors\SluggableBehavior;
use yii\behaviors\TimestampBehavior;
use yii2tech\ar\softdelete\SoftDeleteBehavior;
use wartron\yii2uuid\behaviors\UUIDBehavior;
use yii\helpers\ArrayHelper;
class Page extends \common\models\Page
{
const STATUS_DELETED = -1; //状态：删除
const STATUS_DISABLED = 0; //状态：禁用
const STATUS_DRAFT = 1; //状态：草稿
const STATUS_PUBLISHED = 2; //状态：发布
const SCENARIO_CREATE = 'create';
/**
* @inheritdoc
*/
public function behaviors()
{
return [
'timestampBehavior' => [
'class' => TimestampBehavior::className(),
'attributes' => [
self::EVENT_BEFORE_INSERT => ['created_at', 'updated_at'],
self::EVENT_BEFORE_UPDATE => 'updated_at',
SoftDeleteBehavior::EVENT_BEFORE_SOFT_DELETE => 'updated_at',
]
],
'slug' => [
'class' => SluggableBehavior::className(),
'attribute' => 'title',
'ensureUnique' => true,
'immutable' => true
],
'uuid' => [
'class' => UUIDBehavior::className(),
'column' => 'uuid'
],
'softDeleteBehavior' => [
'class' => SoftDeleteBehavior::className(),
'softDeleteAttributeValues' => [
'status' => self::STATUS_DELETED
],
],
];
}
/**
* {@inheritdoc}
*/
public function scenarios()
{
$scenarios = parent::scenarios();
$scenarios[self::SCENARIO_CREATE] = ['slug', 'title', 'body', 'view', 'status'];
return $scenarios;
}
/**
* @inheritdoc
*/
public function rules()
{
$rules = [
[['title', 'body'], 'required'],
[['slug'], 'unique'],
['view', 'default', 'value' => 0],
['status', 'default', 'value' => self::STATUS_DRAFT],
];
$parentRules = parent::rules();
unset($parentRules[0]);
return ArrayHelper::merge($rules, $parentRules);
}
/**
* {@inheritdoc}
* @return PageQuery the active query used by this AR class.
*/
public static function find()
{
return new PageQuery(get_called_class());
}
}
8、在 Postman 中 POST http://api.github-shuijingwan-yii2-app-advanced.localhost/v1/pages ，报错：iconv(): Detected an illegal character in input string
{
"name": "Exception",
"message": "iconv(): Detected an illegal character in input string",
"code": 0,
"type": "Exception",
"file": "E:\\wwwroot\\github-shuijingwan-yii2-app-advanced\\vendor\\hprose\\hprose\\src\\Hprose\\Client.php",
"line": 383,

"#13 E:\\wwwroot\\github-shuijingwan-yii2-app-advanced\\api\\web\\index.php(17): yii\\base\\Application->run()",
"#14 {main}"
]
}
9、实现行为 \common\behaviors\UUIDBehavior.php，继承至 \wartron\yii2uuid\behaviors\UUIDBehavior，将包含数据的二进制字符串转换为十六进制值，且转化为大写
<?php
namespace common\behaviors;
use wartron\yii2uuid\helpers\Uuid;
class UUIDBehavior extends \wartron\yii2uuid\behaviors\UUIDBehavior
{
public function createUUID()
{
return Uuid::uuid2str(parent::createUUID());
}
}
10、附加行为 common\behaviors\UUIDBehavior，编辑 \common\logics\Page.php
use common\behaviors\UUIDBehavior;
11、在 Postman 中 POST http://api.github-shuijingwan-yii2-app-advanced.localhost/v1/pages ，响应成功
{
"code": 10000,
"message": "创建页面成功",
"data": {
"id": 1,
"uuid": "8F73EF349A0911E8AB1B54EE75D2EBC1",
"slug": "title-20180807-1",
"title": "title-20180807-1",
"body": "body-20180807-1",
"view": 0,
"status": 1,
"created_at": 1533622648,
"updated_at": 1533622648
}
}
12、查看生成的 SQL 语句，符合预期
INSERT INTO `page` (`slug`, `title`, `body`, `view`, `status`, `created_at`, `updated_at`, `uuid`) VALUES ('title-20180807-1', 'title-20180807-1', 'body-20180807-1', 0, 1, 1533622648, 1533622648, '8F73EF349A0911E8AB1B54EE75D2EBC1')
