hyperf 十四 国际化

news 2025/8/6 11:13:31

一 安装

composer require hyperf/translation:v2.2.33

二 配置

1、设置语言文件

文件结构：

        /storage/languages/en/messages.php

        /storage/languages/zh_CH/messages.php

// storage/languages/en/messages.php
return ['welcome' => 'Welcome to our application :test :test2','test' => '{2} TEST1|[3,10] TEST2|[20,*] TEST3',
];// storage/languages/zh_CH/messages.php
return ['welcome' => '欢迎-使用  :test :test2',
];

2、设置配置文件

创建文件 /config/autoload/translation.php。

#/config/autoload/translation.php
return [// 默认语言'locale' => 'zh_CN',// 回退语言，当默认语言的语言文本没有提供时，就会使用回退语言的对应语言文本'fallback_locale' => 'en',// 语言文件存放的文件夹'path' => BASE_PATH . '/storage/languages',
];

三 使用

1、临时设置语言

// storage/languages/zh_CH/messages.php
return ['welcome' => '欢迎-使用',
];#/config/autoload/translation.php
return [// 默认语言'locale' => 'en',// 回退语言，当默认语言的语言文本没有提供时，就会使用回退语言的对应语言文本'fallback_locale' => 'en',// 语言文件存放的文件夹'path' => BASE_PATH . '/storage/languages',
];//App\Controller\TestController
use Hyperf\Di\Annotation\Inject;
use Hyperf\Contract\TranslatorInterface;class TestController
{/*** @Inject* @var TranslatorInterface*/private $translator;public function index(){$value = $this->translator->trans('messages.welcome', [], 'zh_CN');var_dump($value);}
}# 输出
string(26) "欢迎-使用"

 

2、全局函数

// storage/languages/zh_CH/messages.php
return ['welcome' => '欢迎-使用','test1' => '测试',
];// config/autoload/translation.php
return [// 默认语言'locale' => 'zn_CH',// 回退语言，当默认语言的语言文本没有提供时，就会使用回退语言的对应语言文本'fallback_locale' => 'en',// 语言文件存放的文件夹'path' => BASE_PATH . '/storage/languages',
];// App\Controller\TestController
class TestController
{/*** @Inject* @var TranslatorInterface*/private $translator;public function test2(){echo __('message.welcome') . "\n"; //欢迎-使用echo trans('message.welcome') . "\n";//欢迎-使用}
}

4、自定义占位符

// storage/languages/en/messages.php
return ['welcome' => 'Welcome to our application :test :test2',
];// config/autoload/translation.php
return [// 默认语言'locale' => 'en',// 回退语言，当默认语言的语言文本没有提供时，就会使用回退语言的对应语言文本'fallback_locale' => 'en',// 语言文件存放的文件夹'path' => BASE_PATH . '/storage/languages',
];// App\Controller\TestController
class TestController
{/*** @Inject* @var TranslatorInterface*/private $translator;public function test2(){echo __('message.welcome',['test'=>'qqq','test2':'aaa']) . "\n"; //Welcome to our application qqq aaaecho trans('message.welcome',['test'=>'qqq','test2':'aaa']) . "\n";//Welcome to our application qqq aaa}
}

5、复数处理

// storage/languages/en/messages.php
return ['test' => '{2} TEST1|[3,10] TEST2|[20,*] TEST3',
];// config/autoload/translation.php
return [// 默认语言'locale' => 'en',// 回退语言，当默认语言的语言文本没有提供时，就会使用回退语言的对应语言文本'fallback_locale' => 'en',// 语言文件存放的文件夹'path' => BASE_PATH . '/storage/languages',
];// App\Controller\TestController
class TestController
{/*** @Inject* @var TranslatorInterface*/private $translator;public function test2(){echo $this->translator->transChoice('message.test',0)."\n";echo trans_choice('message.test',0) . "\n"; echo trans_choice('message.test',2) . "\n"; echo trans_choice('message.test',4) . "\n";echo trans_choice('message.test',22) . "\n";  }
}//输出TEST1TEST1
TEST1
TEST2
TEST3

四 详解

1、调用

多语言的调用从注入开始，即Hyperf\Translation\Translator::__construct(TranslatorLoaderInterface $loader, string $locale)方法。根据配置文件TranslatorLoaderInterface 对应Hyperf\Translation\FileLoaderFactory类。读取配置文件/storage/languages/translation.path，并返回Hyperf\Translation\FileLoader类。即注入到Translator的构造的TranslatorLoaderInterface 实体类是FileLoader。

若无/storage/languages/translation.path配置文件，可使用默认配置vendor\hyperf\translation\publish\translation.php生成。

php bin/hyperf.php vendor:publish hyperf/translation

使用的语言标志比如en、zn_ch,在上下文中读取和设置。

Translator内调用顺序：

Translator::trans()->Translator::get()->Translator::getLine()->Translator::load()->FileLoader::load()

根据FileLoader::load()调用FileLoader::loadJsonPaths(),可以将不同语言的不同文件统一放到json文件中，使用FileLoader::addJsonPath()设置对应文件。会便利对应文件加载内容，就是对应语言的全部内容。

根据FileLoader::load()调用FileLoader::loadPath(),加载对应文件。比如翻译a.b，a是对应语言的组名，b对应是键名，文件是/storage/languages/对应语言/a.php。

根据FileLoader::load()调用FileLoader::loadNamespaced()，用命名空间加载。这里所谓命名空间就是，对比默认路径，设置一个键名对应非默认路径。也是调用loadPath()实现，不过传入非默认路径，用命名空间获取路径值，用FileLoader::addNamespace()设置命名空间和路径值。

Translator::trans()->Translator::get()->Translator::getLine()->Translator::makeReplacements()->sTranslator::ortReplacements()

根据Translator::ortReplacements(),查询字符串中":占位符"或":占位符全大写"或":占位符首字母大写"。

Translator::transChoice()->Translator::choice()->Translator::makeReplacements()->Translator::getSelector()->MessageSelector::choose()

Translator::choice()也调用Translator::get()但是中心加载了本地语言的标识。Translator::getSelector()将替换值作为数字，MessageSelector::choose()解析字符串、替换字符换中对应数字条件字符，并根据不同语言处理数字，返回最终结果。

全局函数在vendor\hyperf\translation\src\Function.php中，在其composer.json中自动加载。
