laravel 实现切 [ web ] 和 [ api ] 前后端分离换语言包,中英文切换

分手后的思念是犯贱 2022-05-14 10:09 437阅读 0赞

**以上的是以 `web` 为例**

第一步:新建所有的语言包文件 `resources/lang`  
![这里写图片描述][70]  
建立global.php文件

中文的:
        return [
            "test" => "这里是测试",
            "test1" => "继续测试",
            ......
        ];
        英文的:
        return [
            "test" => "this is a test...",
            "test1" => "test again...",
        ......
        ];

就是返回一个数组 `return []` 格式

注意: 各种语言中的元素键名是对应  
第二步:配置文件 `app/config/app.php`

'locale' => 'zh',
    'locales' => ['zh','en','cht'],  //包含的语言种类
    'fallback_locale' => 'cht',

第三步:处理多语言切换的控制器 `SetLangController.php` 以及方法

<?php
    
    namespace App\Http\Controllers\Api;
    
    use App\Http\Controllers\Controller;
    use Illuminate\Http\Request;
    use Illuminate\Support\Facades\App;
    use Illuminate\Support\Facades\Session;
    
    
    class SetLangController extends Controller { 
    
        public function language(Request $request){ 
    
                $lang = $request->lang;
    
                App::setLocale($lang);  //配置默认语言
                $request->session()->put('language',$lang);  //存到session
                return App::getLocale();
        }
    
    }

第四步:中间件的设置-`middleware` (每一次请求，每个中间件都会执行) `app/http/middleware`下添加中间件 `Language.php` 内容如下

<?php
    
    namespace App\Http\Middleware;
    
    use Closure;
    use Illuminate\Support\Facades\App;
    use Illuminate\Support\Facades\Config;
    use Illuminate\Support\Facades\Session;
    
    class Language { 
        /** * Handle an incoming request. * * @param \Illuminate\Http\Request $request * @param \Closure $next * @return mixed */
        public function handle($request, Closure $next) { 
    
    
            if (Session::has('language') AND in_array(Session::get('language'), Config::get('app.locales'))) {
    
                App::setLocale(Session::get('language'));
    
            }else {
    
                App::setLocale(Config::get('app.locale'));
    
            }
    
            return $next($request);
        }
    }

配置`app/http/middleware/kernel.php` 添加 `Language`

protected $middlewareGroups = [ 'web' => [ \App\Http\Middleware\EncryptCookies::class, \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class, \Illuminate\Session\Middleware\StartSession::class, // \Illuminate\Session\Middleware\AuthenticateSession::class, \Illuminate\View\Middleware\ShareErrorsFromSession::class, \App\Http\Middleware\VerifyCsrfToken::class, \Illuminate\Routing\Middleware\SubstituteBindings::class, \App\Http\Middleware\Language::class, //这里 ], 'api' => [ 'throttle:60,1', 'bindings', ], ];

基本上就是这样了,试试看,希望可以对你有帮助.告辞

--------------------

**前后端分离,切换语言包**

以下为前后端分离是`laravel`无法使用`session` ,下面讲解如何使用`api`切换语言包

以上不变,在中间中是需要变化一下:  
一、在`Kernel.php`中

protected $routeMiddleware = [
            'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
            'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
            'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
            'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
            ...
            ...
        'switch_lang'=>\Illuminate\Session\Middleware\StartSession::class,//这里开启session
            'lang'=>\App\Http\Middleware\Language::class,  //这里自己定义的切换语言包
    
    
        ];

二、在`api`路由中

<?php
    
    $api = app("Dingo\Api\Routing\Router");
    $api->version('v1', function ($api) { 
    
        $api->group(["namespace" => "App\Http\Controllers\Api",'middleware'=>['auth.token','auth:api','permissions','switch_lang','lang']],
            function ($api) { 
            //用户认证之后在这里写api
            $api->post('college_alterlist','ResourceController@collegeList');
    
        });
    
        $api->group(["namespace" => "App\Http\Controllers\Api"], function ($api) { 
            //不需要做认证在这里写api
            $api->post('login', 'TokenController@login');
        });
    
        //不需要权限认证
        $api->group(["namespace" => "App\Http\Controllers\Api",'middleware'=>['auth.token','auth:api','switch_lang']], function ($api) { 
            $api->post('setLang','SetLangController@language');
        });
    });

到此结束
