如何在所需的PHP文件中使用Illuminate数据库实例

标签: php slim illuminate-container

我正在尝试使用Slim PHP设置一个restful API。这是我第一次使用微框架,我正在尝试用它构建一个应用程序,以便它可以保持可维护状态。

我正在尝试构建我的应用程序:

root
- index.php
- composer.json
- app
- - routes
- - - session.php
- - lib
- - - functions.php
- - vendor
- - - Composer Vendor dirs and files

我正在使用illuminate访问我的MySQL数据库,而我在index.php文件中的所有代码都工作正常。当我试图将我的身份验证功能分解到session.php时,我无法再访问illuminate实例。我按照github页面中的标准设置

use \Slim\Slim;
use Illuminate\Database\Capsule\Manager as Capsule;

$capsule = new Capsule;

$capsule->addConnection([
'driver'    => 'mysql',
'host'      => 'localhost',
'database'  => 'database',
'username'  => 'root',
'password'  => 'password',
'charset'   => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix'    => '',
]);

// Set the event dispatcher used by Eloquent models... (optional)
use Illuminate\Events\Dispatcher;
use Illuminate\Container\Container;
$capsule->setEventDispatcher(new Dispatcher(new Container));

// Make this Capsule instance available globally via static methods... (optional)
$capsule->setAsGlobal();

// Setup the Eloquent ORM... (optional; unless you've used setEventDispatcher())
$capsule->bootEloquent();

$app = new Slim();

//get login routes
require 'app/routes/session.php';

$app->get("/", function() use ($app){

$app->render(200,array(
        'msg' => 'welcome',
    ));
});

这是我的session.php:

$app->post("/login", function() use ($app){
    $postVarsAll = $app->request->post();
    if( isset($postVarsAll['password']) && isset($postVarsAll['username']))
    {
        //Get associated user
        $app->render(200,array(
            'msg' => print_r(Capsule,true)
        ));
        $user = Capsule::table('user')->where('username','=',$postVarsAll['username'])-  >first();
    }else{
    $app->render(200, array(
        "msg" => "no params",
        "params" => $postVarsAll
    ));
    }

});

这会引发500错误并告诉我:

"msg": "NOTICE: Use of undefined constant Capsule - assumed 'Capsule'",

我希望在session.php中使用Capsule实例。有谁知道怎么做?

如果我取出Capsule,则路线可以正常工作。

感谢您的帮助!

修改

$app->post("/login", function() use ($app,$capsule){
    $postVarsAll = $app->request->post();
    if( isset($postVarsAll['password']) && isset($postVarsAll['username']))
    {
        //Get associated user
        $app->render(200,array(
            'msg' => print_r($capsule,true)
        ));
     return;
     ...

用这个我得到完整的胶囊对象。

感谢volkinc寻找答案。 我可以使用$capsule->table("user")->...来满足我的查询需求。

'msg' => print_r(Capsule,true)

尝试

'msg' => print_r($capsule,true)
