title: init方法
|
|
||||||
---
|
|
||||||
这节分析这一行代码的作用
|
|
||||||
```php
|
|
||||||
Hyperf\Di\ClassLoader::init();
|
|
||||||
```
|
|
||||||
`init`方法有三个可选参数，默认是不传参数进来
|
|
||||||
```php
|
|
||||||
public static function init(?string $proxyFileDirPath = null, ?string $configDir = null, ?ScanHandlerInterface $handler = null): void
|
|
||||||
{
|
|
||||||
// 代理文件目录
|
|
||||||
if (! $proxyFileDirPath) {
|
|
||||||
$proxyFileDirPath = BASE_PATH . '/runtime/container/proxy/';
|
|
||||||
}
|
|
||||||
|
|
||||||
// 配置文件目录
|
|
||||||
if (! $configDir) {
|
|
||||||
$configDir = BASE_PATH . '/config/';
|
|
||||||
}
|
|
||||||
|
|
||||||
// 扫描器，用来扫描类文件并生成类映射
|
|
||||||
// 利用 PHP 的 pcntl 扩展提供的功能来进行并发扫描，以加快扫描速度
|
|
||||||
if (! $handler) {
|
|
||||||
$handler = new PcntlScanHandler();
|
|
||||||
}
|
|
||||||
// 获取composer的自动加载器实例
|
|
||||||
$composerLoader = Composer::getLoader();
|
|
||||||
|
|
||||||
// 这就没啥说的， 如果.env文件存在，就加载.env文件
|
|
||||||
// 使用vlucas/phpdotenv库
|
|
||||||
if (file_exists(BASE_PATH . '/.env')) {
|
|
||||||
static::loadDotenv();
|
|
||||||
}
|
|
||||||
|
|
||||||
// Scan by ScanConfig to generate the reflection class map
|
|
||||||
$config = ScanConfig::instance($configDir);
|
|
||||||
$composerLoader->addClassMap($config->getClassMap());
|
|
||||||
|
|
||||||
$scanner = new Scanner($config, $handler);
|
|
||||||
$composerLoader->addClassMap(
|
|
||||||
$scanner->scan($composerLoader->getClassMap(), $proxyFileDirPath)
|
|
||||||
);
|
|
||||||
|
|
||||||
// Initialize Lazy Loader. This will prepend LazyLoader to the top of autoload queue.
|
|
||||||
LazyLoader::bootstrap($configDir);
|
|
||||||
}
|
|
||||||
|
|
||||||
protected static function loadDotenv(): void
|
|
||||||
{
|
|
||||||
$repository = RepositoryBuilder::createWithNoAdapters()
|
|
||||||
->addAdapter(Adapter\PutenvAdapter::class)
|
|
||||||
->immutable()
|
|
||||||
->make();
|
|
||||||
|
|
||||||
Dotenv::create($repository, [BASE_PATH])->load();
|
|
||||||
}
|
|
||||||
```
|
|
||||||
### instance方法
|
|
||||||
看这行，`instance`方法创建一个`ScanConfig`实例，用于加载并解析目录下的配置文件，并生成类映射等扫描相关的配置信息。不理解可以往下看，
|
|
||||||
```php
|
|
||||||
$config = ScanConfig::instance($configDir);
|
|
||||||
```
|
|
||||||
进入该方法，
|
|
||||||
```php
|
|
||||||
public static function instance(string $configDir): self
|
|
||||||
{
|
|
||||||
// 如果该实例存在，则直接返回该实例
|
|
||||||
if (self::$instance) {
|
|
||||||
return self::$instance;
|
|
||||||
}
|
|
||||||
|
|
||||||
$configDir = rtrim($configDir, '/');
|
|
||||||
|
|
||||||
[$config, $serverDependencies, $cacheable] = static::initConfigByFile($configDir);
|
|
||||||
// 这里返回该实例
|
|
||||||
return self::$instance = new self(
|
|
||||||
$cacheable,
|
|
||||||
$configDir,
|
|
||||||
$config['paths'] ?? [],
|
|
||||||
$serverDependencies ?? [],
|
|
||||||
$config['ignore_annotations'] ?? [],
|
|
||||||
$config['global_imports'] ?? [],
|
|
||||||
$config['collectors'] ?? [],
|
|
||||||
$config['class_map'] ?? []
|
|
||||||
);
|
|
||||||
}
|
|
||||||
```
|
|
||||||
#### initConfigByFile方法
|
|
||||||
配置的获取在该方法中，
|
|
||||||
```php
|
|
||||||
private static function initConfigByFile(string $configDir): array
|
|
||||||
{
|
|
||||||
$config = [];
|
|
||||||
$configFromProviders = [];
|
|
||||||
$cacheable = false;
|
|
||||||
// 该class是hyperf config包中带的
|
|
||||||
if (class_exists(ProviderConfig::class)) {
|
|
||||||
$configFromProviders = ProviderConfig::load();
|
|
||||||
}
|
|
||||||
|
|
||||||
//...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
继续往下看，`ProviderConfig::load()`进入该方法，
|
|
||||||
```php
|
|
||||||
public static function load(): array
|
|
||||||
{
|
|
||||||
// 如果未赋值，则进行赋值
|
|
||||||
if (! static::$providerConfigs) {
|
|
||||||
// 该行是从composer.json中获取配置信息，并返回数组
|
|
||||||
// 这里会获得所有的服务提供者信息
|
|
||||||
$providers = Composer::getMergedExtra('hyperf')['config'] ?? [];
|
|
||||||
static::$providerConfigs = static::loadProviders($providers);
|
|
||||||
}
|
|
||||||
return static::$providerConfigs;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
这里用到了[ConfigProvider 机制](https://hyperf.wiki/3.1/#/zh-cn/component-guide/configprovider)，参考官网讲解。
|
|
||||||
`Composer::getMergedExtra`获取`composer.json`文件中的配置信息，内容如下
|
|
||||||
|
|
||||||
打印获取的内容如下，是所有服务提供者的数组
|
|
||||||
|
|
||||||
接下来查看`loadProviders`方法
|
|
||||||
```php
|
|
||||||
protected static function loadProviders(array $providers): array
|
|
||||||
{
|
|
||||||
$providerConfigs = [];
|
|
||||||
// 循环所有服务提供者
|
|
||||||
foreach ($providers as $provider) {
|
|
||||||
// 如果是字符串，且存在该类，且该类存在__invoke方法
|
|
||||||
if (is_string($provider) && class_exists($provider) && method_exists($provider, '__invoke')) {
|
|
||||||
// 当通过方法调用类时，会触发__invoke方法
|
|
||||||
// 所以(new $provider())()相当于执行服务提供者的__invoke方法
|
|
||||||
$providerConfigs[] = (new $provider())();
|
|
||||||
}
|
|
||||||
}
|
|
||||||
|
|
||||||
return static::merge(...$providerConfigs);
|
|
||||||
}
|
|
||||||
```
|
|
||||||
我们以`hyperf/config`包为例，打开目录下`ConfigProvider`类，打开`__invoke`方法，会发现，这里返回的是一个配置数组，代码如下，
|
|
||||||
```php
|
|
||||||
class ConfigProvider
|
|
||||||
{
|
|
||||||
public function __invoke(): array
|
|
||||||
{
|
|
||||||
return [
|
|
||||||
'dependencies' => [
|
|
||||||
ConfigInterface::class => ConfigFactory::class,
|
|
||||||
],
|
|
||||||
'aspects' => [
|
|
||||||
ValueAspect::class,
|
|
||||||
],
|
|
||||||
'listeners' => [
|
|
||||||
RegisterPropertyHandlerListener::class,
|
|
||||||
],
|
|
||||||
];
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
最终生成的`$providerConfigs`数组格式如下，每个服务提供者都会生成一个数组。
|
|
||||||
```php
|
|
||||||
array(22) {
|
|
||||||
[0]=>
|
|
||||||
array(5) {
|
|
||||||
["dependencies"]=>
|
|
||||||
array(1) {
|
|
||||||
["Psr\SimpleCache\CacheInterface"]=>
|
|
||||||
string(18) "Hyperf\Cache\Cache"
|
|
||||||
}
|
|
||||||
["listeners"]=>
|
|
||||||
array(1) {
|
|
||||||
[0]=>
|
|
||||||
string(36) "Hyperf\Cache\Listener\DeleteListener"
|
|
||||||
}
|
|
||||||
["annotations"]=>
|
|
||||||
array(1) {
|
|

["scan"]=>
|
|
||||||
array(1) {
|
|
||||||
["collectors"]=>
|
|
||||||
array(1) {
|
|
||||||
[0]=>
|
|
||||||
string(35) "Hyperf\Cache\CacheListenerCollector"
|
|
||||||
}
|
|
||||||
}
|
|
||||||
}
|
|
||||||
["aspects"]=>
|
|
||||||
array(5) {
|
|
||||||
[0]=>
|
|
||||||
string(35) "Hyperf\Cache\Aspect\CacheableAspect"
|
|
||||||
[1]=>
|
|
||||||
string(36) "Hyperf\Cache\Aspect\CacheAheadAspect"
|
|
||||||
[2]=>
|
|
||||||
string(36) "Hyperf\Cache\Aspect\CacheEvictAspect"
|
|
||||||
[3]=>
|
|
||||||
string(34) "Hyperf\Cache\Aspect\CachePutAspect"
|
|
||||||
[4]=>
|
|
||||||
string(35) "Hyperf\Cache\Aspect\FailCacheAspect"
|
|
||||||
}
|
|
||||||
["publish"]=>
|
|
||||||
array(1) {
|
|
||||||
[0]=>
|
|
||||||
array(4) {
|
|
||||||
["id"]=>
|
|
||||||
string(6) "config"
|
|
||||||
["description"]=>
|
|
||||||
string(21) "The config for cache."
|
|
||||||
["source"]=>
|
|
||||||
string(74) "/data/project/hyperf-skeleton/vendor/hyperf/cache/src/../publish/cache.php"
|
|
||||||
["destination"]=>
|
|
||||||
string(55) "/data/project/hyperf-skeleton/config/autoload/cache.php"
|
|
||||||
}
|
|
||||||
}
|
|
||||||
}
|
|
||||||
//...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
最后再看`return static::merge(...$providerConfigs);`这一行，查看`static::merge`方法，该方法是将所有服务提供者的配置数组进行合并，最终返回一个数组。
|
|
||||||
```php
|
|
||||||
protected static function merge(...$arrays): array
|
|
||||||
{
|
|
||||||
if (empty($arrays)) {
|
|
||||||
return [];
|
|
||||||
}
|
|
||||||
// 递归地合并一个或多个数组,
|
|
||||||
// 如果输入的数组中有相同的字符串键名，则这些值会被合并到一个数组中去
|
|
||||||
$result = array_merge_recursive(...$arrays);
|
|
||||||
// 如果存在dependencies key，则对依赖进行合并
|
|
||||||
if (isset($result['dependencies'])) {
|
|
||||||
$result['dependencies'] = [];
|
|
||||||
foreach ($arrays as $item) {
|
|
||||||
foreach ($item['dependencies'] ?? [] as $key => $value) {
|
|
||||||
$depend = $result['dependencies'][$key] ?? null;
|
|
||||||
if (! $depend instanceof PriorityDefinition) {
|
|
||||||
$result['dependencies'][$key] = $value;
|
|
||||||
continue;
|
|
||||||
}
|
|
||||||
|
|
||||||
if ($value instanceof PriorityDefinition) {
|
|
||||||
$depend->merge($value);
|
|
||||||
}
|
|
||||||
}
|
|
||||||
}
|
|
||||||
}
|
|
||||||
// 返回合并后的配置数组
|
|
||||||
return $result;
|
|
||||||
}
|
|
||||||
```
|
|
||||||
以上，`ProviderConfig::load()`方法走完。
|
|
||||||
往下看，以下是将config目录下配置与上面获取的配置进行合并，存在重复则配置文件优先
|
|
||||||
```php
|
|
||||||
$serverDependencies = $configFromProviders['dependencies'] ?? [];
|
|
||||||
if (file_exists($configDir . '/autoload/dependencies.php')) {
|
|
||||||
$definitions = include $configDir . '/autoload/dependencies.php';
|
|
||||||
$serverDependencies = array_replace($serverDependencies, $definitions ?? []);
|
|
||||||
}
|
|
||||||
|
|
||||||
$config = static::allocateConfigValue($configFromProviders['annotations'] ?? [], $config);
|
|
||||||
|
|
||||||
// 这里是注解相关的配置，回来在分析
|
|
||||||
if (file_exists($configDir . '/autoload/annotations.php')) {
|
|
||||||
$annotations = include $configDir . '/autoload/annotations.php';
|
|
||||||
$config = static::allocateConfigValue($annotations, $config);
|
|
||||||
}
|
|
||||||
|
|
||||||
// Load the config/config.php and merge the config
|
|
||||||
if (file_exists($configDir . '/config.php')) {
|
|
||||||
$configContent = include $configDir . '/config.php';
|
|
||||||
$appEnv = $configContent['app_env'] ?? 'dev';
|
|
||||||
$cacheable = value($configContent['scan_cacheable'] ?? $appEnv === 'prod');
|
|
||||||
if (isset($configContent['annotations'])) {
|
|
||||||
$config = static::allocateConfigValue($configContent['annotations'], $config);
|
|
||||||
}
|
|
||||||
}
|
|
||||||
|
|
||||||
return [$config, $serverDependencies, $cacheable];
|
|
||||||
```
|
|
||||||
`instance`方法的三个返回值都已经清楚，接下来返回自身实例
|
|
||||||
```php
|
|
||||||
return self::$instance = new self(
|
|
||||||
$cacheable,
|
|
||||||
$configDir,
|
|
||||||
$config['paths'] ?? [],
|
|
||||||
$serverDependencies ?? [],
|
|
||||||
$config['ignore_annotations'] ?? [],
|
|
||||||
$config['global_imports'] ?? [],
|
|
||||||
$config['collectors'] ?? [],
|
|
||||||
$config['class_map'] ?? []
|
|
||||||
);
|
|
||||||
```
|
|
||||||
现在，`config`文件配置已经得到，
|
|
||||||
```php
|
|
||||||
$config = ScanConfig::instance($configDir);
|
|
||||||
```
|
|
||||||
分析下一行，
|
|
||||||
```php
|
|
||||||
// 将提供的类映射添加到 Composer 的自动加载器中
|
|
||||||
$composerLoader->addClassMap($config->getClassMap());
|
|
||||||
```
|
|
||||||
由上面配置文件可知，默认情况下，`class_map`为空。

## 初始化依赖注入 (DI) 容器
|
||||||
|
```php
|
||||||
|
(function () {
|
||||||
|
|
||||||
|
Hyperf\Di\ClassLoader::init(); // [!code focus]

|
||||||
|
$application->run();
|
||||||
|
})();
|
||||||
|
```
|
||||||
|
`init`方法有三个可选参数，默认是不传参数进来
|
||||||
|
```php
|
||||||
|
public static function init(?string $proxyFileDirPath = null, ?string $configDir = null, ?ScanHandlerInterface $handler = null): void
|
||||||
|
{
|
||||||
|
// 代理文件目录
|
||||||
|
if (! $proxyFileDirPath) {
|
||||||
|
$proxyFileDirPath = BASE_PATH . '/runtime/container/proxy/';
|
||||||
|
}
|
||||||
|
|
||||||
|
// 配置文件目录
|
||||||
|
if (! $configDir) {
|
||||||
|
$configDir = BASE_PATH . '/config/';
|
||||||
|
}
|
||||||
|
|
||||||
|
// 扫描器，用来扫描类文件并生成类映射
|
||||||
|
// 利用 PHP 的 pcntl 扩展提供的功能来进行并发扫描，以加快扫描速度
|
||||||
|
if (! $handler) {
|
||||||
|
$handler = new PcntlScanHandler();
|
||||||
|
}
|
||||||
|
// 获取composer的自动加载器实例
|
||||||
|
$composerLoader = Composer::getLoader();
|
||||||
|
|
||||||
|
// 加载.env文件 // [!code focus:17]
|
||||||
|
// 使用的是vlucas/phpdotenv库
|
||||||
|
if (file_exists(BASE_PATH . '/.env')) {
|
||||||
|
static::loadDotenv();
|
||||||
|
}
|
||||||
|
|
||||||
|
// 通过 ScanConfig 扫描并生成反射类映射
|
||||||
|
$config = ScanConfig::instance($configDir);
|
||||||
|
$composerLoader->addClassMap($config->getClassMap());
|
||||||
|
|
||||||
|
$scanner = new Scanner($config, $handler);
|
||||||
|
$composerLoader->addClassMap(
|
||||||
|
$scanner->scan($composerLoader->getClassMap(), $proxyFileDirPath)
|
||||||
|
);
|
||||||
|
|
||||||
|
// Initialize Lazy Loader. This will prepend LazyLoader to the top of autoload queue.
|
||||||
|
LazyLoader::bootstrap($configDir);
|
||||||
|
}
|
||||||
|
|
||||||
|
protected static function loadDotenv(): void
|
||||||
|
{
|
||||||
|
$repository = RepositoryBuilder::createWithNoAdapters()
|
||||||
|
->addAdapter(Adapter\PutenvAdapter::class)
|
||||||
|
->immutable()
|
||||||
|
->make();
|
||||||
|
|
||||||
|
Dotenv::create($repository, [BASE_PATH])->load();
|
||||||
|
}
|
||||||
|
```
|
||||||
|
### 读取配置目录
|
||||||
|
看这行，`instance`方法创建一个`ScanConfig`实例，用于加载并解析目录下的配置文件，并生成类映射等扫描相关的配置信息。
|
||||||
|
```php
|
||||||
|
$config = ScanConfig::instance($configDir);
|
||||||
|
|
||||||
|
public static function instance(string $configDir): self // [!code focus:20]
|
||||||
|
{
|
||||||
|
// 如果该实例存在，则直接返回该实例
|
||||||
|
if (self::$instance) {
|
||||||
|
return self::$instance;
|
||||||
|
}
|
||||||
|
|
||||||
|
$configDir = rtrim($configDir, '/');
|
||||||
|
|
||||||
|
[$config, $serverDependencies, $cacheable] = static::initConfigByFile($configDir);
|
||||||
|
// 这里返回该实例
|
||||||
|
return self::$instance = new self(
|
||||||
|
$cacheable,
|
||||||
|
$configDir,
|
||||||
|
$config['paths'] ?? [],
|
||||||
|
$serverDependencies ?? [],
|
||||||
|
$config['ignore_annotations'] ?? [],
|
||||||
|
$config['global_imports'] ?? [],
|
||||||
|
$config['collectors'] ?? [],
|
||||||
|
$config['class_map'] ?? []
|
||||||
|
);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
从`initConfigByFile`方法中，在指定目录解析出对应的`$config`、`$serverDependencies` 和 `$cacheable`三个变量。该方法具体实现如下，
|
||||||
|
```php
|
||||||
|
private static function initConfigByFile(string $configDir): array
|
||||||
|
{
|
||||||
|
$config = [];
|
||||||
|
$configFromProviders = [];
|
||||||
|
$cacheable = false;
|
||||||
|
if (class_exists(ProviderConfig::class)) { // [!code warning:3]
|
||||||
|
$configFromProviders = ProviderConfig::load();
|
||||||
|
}
|
||||||
|
|
||||||
|
$serverDependencies = $configFromProviders['dependencies'] ?? [];
|
||||||
|
if (file_exists($configDir . '/autoload/dependencies.php')) {
|
||||||
|
$definitions = include $configDir . '/autoload/dependencies.php';
|
||||||
|
$serverDependencies = array_replace($serverDependencies, $definitions ?? []);
|
||||||
|
}
|
||||||
|
|
||||||
|
$config = static::allocateConfigValue($configFromProviders['annotations'] ?? [], $config);
|
||||||
|
|
||||||
|
// Load the config/autoload/annotations.php and merge the config
|
||||||
|
if (file_exists($configDir . '/autoload/annotations.php')) {
|
||||||
|
$annotations = include $configDir . '/autoload/annotations.php';
|
||||||
|
$config = static::allocateConfigValue($annotations, $config);
|
||||||
|
}
|
||||||
|
|
||||||
|
// Load the config/config.php and merge the config
|
||||||
|
if (file_exists($configDir . '/config.php')) {
|
||||||
|
$configContent = include $configDir . '/config.php';
|
||||||
|
$appEnv = $configContent['app_env'] ?? 'dev';
|
||||||
|
$cacheable = value($configContent['scan_cacheable'] ?? $appEnv === 'prod');
|
||||||
|
if (isset($configContent['annotations'])) {
|
||||||
|
$config = static::allocateConfigValue($configContent['annotations'], $config);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
return [$config, $serverDependencies, $cacheable];
|
||||||
|
}
|
||||||
|
```
|
||||||
|
#### 获取项目配置信息
|
||||||
|
使用`ProviderConfig::load()`方法，获取项目配置信息，该方法实现如下，
|
||||||
|
```php
|
||||||
|
namespace Hyperf\Config;
|
||||||
|
|
||||||
|
use Hyperf\Di\Definition\PriorityDefinition;
|
||||||
|
use Hyperf\Support\Composer;
|
||||||
|
|
||||||
|
use function class_exists;
|
||||||
|
use function is_string;
|
||||||
|
use function method_exists;
|
||||||
|
/**
|
||||||
|
* Provider config allow the components set the configs to application.
|
||||||
|
*/
|
||||||
|
class ProviderConfig // [!code focus:4]
|
||||||
|
{
|
||||||
|
// 项目配置数组
|
||||||
|
private static array $providerConfigs = [];
|
||||||
|
|
||||||
|
/**
|
||||||
|
* 从组件中加载和合并所有的服务提供者
|
||||||
|
*/
|
||||||
|
public static function load(): array // [!code focus:8]
|
||||||
|
{
|
||||||
|
if (! static::$providerConfigs) {
|
||||||
|
$providers = Composer::getMergedExtra('hyperf')['config'] ?? [];
|
||||||
|
static::$providerConfigs = static::loadProviders($providers);
|
||||||
|
}
|
||||||
|
return static::$providerConfigs;
|
||||||
|
}
|
||||||
|
|
||||||
|
public static function clear(): void
|
||||||
|
{
|
||||||
|
static::$providerConfigs = [];
|
||||||
|
}
|
||||||
|
|
||||||
|
protected static function loadProviders(array $providers): array // [!code focus:11]
|
||||||
|
{
|
||||||
|
$providerConfigs = [];
|
||||||
|
foreach ($providers as $provider) {
|
||||||
|
if (is_string($provider) && class_exists($provider) && method_exists($provider, '__invoke')) {
|
||||||
|
$providerConfigs[] = (new $provider())();
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
return static::merge(...$providerConfigs);
|
||||||
|
}
|
||||||
|
|
||||||
|
protected static function merge(...$arrays): array
|
||||||
|
{
|
||||||
|
if (empty($arrays)) {
|
||||||
|
return [];
|
||||||
|
}
|
||||||
|
$result = array_merge_recursive(...$arrays);
|
||||||
|
if (isset($result['dependencies'])) {
|
||||||
|
$result['dependencies'] = [];
|
||||||
|
foreach ($arrays as $item) {
|
||||||
|
foreach ($item['dependencies'] ?? [] as $key => $value) {
|
||||||
|
$depend = $result['dependencies'][$key] ?? null;
|
||||||
|
if (! $depend instanceof PriorityDefinition) {
|
||||||
|
$result['dependencies'][$key] = $value;
|
||||||
|
continue;
|
||||||
|
}
|
||||||
|
|
||||||
|
if ($value instanceof PriorityDefinition) {
|
||||||
|
$depend->merge($value);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
return $result;
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
这里用到了[ConfigProvider 机制](https://hyperf.wiki/3.1/#/zh-cn/component-guide/configprovider)，参考官网讲解。
|
||||||
|
|
||||||
|
简单来说，`Hyperf`会读取每个组件包`composer.json`中指定的信息，作为数组返回。`Composer::getMergedExtra`获取`composer.json`文件中的配置信息
|
||||||
|
，打印获取的内容如下
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
接下来查看`loadProviders`方法，
|
||||||
|
```php
|
||||||
|
protected static function loadProviders(array $providers): array
|
||||||
|
{
|
||||||
|
$providerConfigs = [];
|
||||||
|
// 循环所有服务提供者 // [!code focus:11]
|
||||||
|
foreach ($providers as $provider) {
|
||||||
|
// 如果是字符串，且存在该类，且该类存在__invoke方法
|
||||||
|
if (is_string($provider) && class_exists($provider) && method_exists($provider, '__invoke')) {
|
||||||
|
// 当通过方法调用类时，会触发__invoke魔术方法
|
||||||
|
// 所以(new $provider())()相当于执行服务提供者的__invoke方法
|
||||||
|
$providerConfigs[] = (new $provider())();
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
return static::merge(...$providerConfigs);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
我们以`hyperf/config`包为例，打开目录下`ConfigProvider`类，打开`__invoke`方法，会发现，这里返回的是一个配置数组，代码如下，
|
||||||
|
```php
|
||||||
|
class ConfigProvider
|
||||||
|
{
|
||||||
|
public function __invoke(): array
|
||||||
|
{
|
||||||
|
return [
|
||||||
|
'dependencies' => [
|
||||||
|
ConfigInterface::class => ConfigFactory::class,
|
||||||
|
],
|
||||||
|
'aspects' => [
|
||||||
|
ValueAspect::class,
|
||||||
|
],
|
||||||
|
'listeners' => [
|
||||||
|
RegisterPropertyHandlerListener::class,
|
||||||
|
],
|
||||||
|
];
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
`$providerConfigs`数组格式如下，每个服务提供者都会生成一个数组。
|
||||||
|
```php
|
||||||
|
array(3) {
|
||||||
|
["dependencies"]=>
|
||||||
|
array(1) {
|
||||||
|
["Hyperf\Contract\ConfigInterface"]=>
|
||||||
|
string(27) "Hyperf\Config\ConfigFactory"
|
||||||
|
}
|
||||||
|
["aspects"]=>
|
||||||
|
array(1) {
|
||||||
|
[0]=>
|
||||||
|
string(36) "Hyperf\Config\Annotation\ValueAspect"
|
||||||
|
}
|
||||||
|
["listeners"]=>
|
||||||
|
array(1) {
|
||||||
|
[0]=>
|
||||||
|
string(54) "Hyperf\Config\Listener\RegisterPropertyHandlerListener"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
最后通过`static::merge`方法，将所有服务提供者的配置数组进行合并，最终返回一个数组。
|
||||||
|
```php
|
||||||
|
protected static function merge(...$arrays): array
|
||||||
|
{
|
||||||
|
if (empty($arrays)) {
|
||||||
|
return [];
|
||||||
|
}
|
||||||
|
// 递归地合并一个或多个数组,
|
||||||
|
// 如果输入的数组中有相同的字符串键名，则这些值会被合并到一个数组中去
|
||||||
|
$result = array_merge_recursive(...$arrays);
|
||||||
|
// 如果存在dependencies key，则对依赖进行合并
|
||||||
|
if (isset($result['dependencies'])) {
|
||||||
|
$result['dependencies'] = [];
|
||||||
|
foreach ($arrays as $item) {
|
||||||
|
foreach ($item['dependencies'] ?? [] as $key => $value) {
|
||||||
|
$depend = $result['dependencies'][$key] ?? null;
|
||||||
|
if (! $depend instanceof PriorityDefinition) {
|
||||||
|
$result['dependencies'][$key] = $value;
|
||||||
|
continue;
|
||||||
|
}
|
||||||
|
|
||||||
|
if ($value instanceof PriorityDefinition) {
|
||||||
|
$depend->merge($value);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
}
|
||||||
|
// 返回合并后的配置数组
|
||||||
|
return $result;
|
||||||
|
}
|
||||||
|
```
|
||||||
|
以上，`ProviderConfig::load()`方法走完。
|
||||||
|
|
||||||
|
|
||||||
|
回到`initConfigByFile`方法，往下看，将`config`目录下配置与上面获取的配置进行合并，存在重复则配置文件优先
|
||||||
|
```php
|
||||||
|
private static function initConfigByFile(string $configDir): array
|
||||||
|
{
|
||||||
|
$config = [];
|
||||||
|
$configFromProviders = [];
|
||||||
|
$cacheable = false;
|
||||||
|
if (class_exists(ProviderConfig::class)) {
|
||||||
|
$configFromProviders = ProviderConfig::load();
|
||||||
|
}
|
||||||
|
// 加载 autoload 目录下的 dependencies.php 文件，并合并依赖配置
|
||||||
|
$serverDependencies = $configFromProviders['dependencies'] ?? []; // [!code focus:25]
|
||||||
|
if (file_exists($configDir . '/autoload/dependencies.php')) {
|
||||||
|
$definitions = include $configDir . '/autoload/dependencies.php';
|
||||||
|
$serverDependencies = array_replace($serverDependencies, $definitions ?? []);
|
||||||
|
}
|
||||||
|
// 将 Provider 配置中的 annotations 值分配给 config
|
||||||
|
$config = static::allocateConfigValue($configFromProviders['annotations'] ?? [], $config);
|
||||||
|
|
||||||
|
// 加载 autoload 目录下的 annotations.php 文件，并合并配置
|
||||||
|
if (file_exists($configDir . '/autoload/annotations.php')) {
|
||||||
|
$annotations = include $configDir . '/autoload/annotations.php';
|
||||||
|
$config = static::allocateConfigValue($annotations, $config);
|
||||||
|
}
|
||||||
|
|
||||||
|
// 加载 config 目录下的 config.php 文件，合并
|
||||||
|
if (file_exists($configDir . '/config.php')) {
|
||||||
|
$configContent = include $configDir . '/config.php';
|
||||||
|
$appEnv = $configContent['app_env'] ?? 'dev';
|
||||||
|
$cacheable = value($configContent['scan_cacheable'] ?? $appEnv === 'prod');
|
||||||
|
if (isset($configContent['annotations'])) {
|
||||||
|
$config = static::allocateConfigValue($configContent['annotations'], $config);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
return [$config, $serverDependencies, $cacheable];
|
||||||
|
}
|
||||||
|
```
|
||||||
|
- `$config` 包含合并后的注解配置数组
|
||||||
|
- `serverDependencies` 包含合并后的依赖配置数组
|
||||||
|
- `cacheable` 布尔值，表示扫描结果是否可缓存(由`config`文件中的`scan_cacheable`参数决定)
|
||||||
|
|
||||||
|
接下来返回自身实例
|
||||||
|
```php
|
||||||
|
return self::$instance = new self(
|
||||||
|
$cacheable,
|
||||||
|
$configDir,
|
||||||
|
$config['paths'] ?? [],
|
||||||
|
$serverDependencies ?? [],
|
||||||
|
$config['ignore_annotations'] ?? [],
|
||||||
|
$config['global_imports'] ?? [],
|
||||||
|
$config['collectors'] ?? [],
|
||||||
|
$config['class_map'] ?? []
|
||||||
|
);
|
||||||
|
```
|
||||||
|
现在，`config`文件配置已经得到，
|
||||||
|
|
||||||
|
```php
|
||||||
|
$config = ScanConfig::instance($configDir);
|
||||||
|
```
|
||||||
|
|
||||||
|
|
||||||
|
### 扫描并更新 `composerLoader` 的类映射表
|
||||||
|
```php
|
||||||
|
public static function init(?string $proxyFileDirPath = null, ?string $configDir = null, ?ScanHandlerInterface $handler = null): void
|
||||||
|
{
|
||||||
|
if (! $proxyFileDirPath) {
|
||||||
|
// This dir is the default proxy file dir path of Hyperf
|
||||||
|
$proxyFileDirPath = BASE_PATH . '/runtime/container/proxy/';
|
||||||
|
}
|
||||||
|
|
||||||
|
if (! $configDir) {
|
||||||
|
// This dir is the default proxy file dir path of Hyperf
|
||||||
|
$configDir = BASE_PATH . '/config/';
|
||||||
|
}
|
||||||
|
|
||||||
|
if (! $handler) {
|
