Laravel 4.2:在控制器中包含一个PHP文件(库)

Question

我正在使用Laravel 4.2做一个项目,我需要在控制器中包含一个PHP文件(一个将PDF转换为文本的库),然后返回带有文本的变量,任何想法如何？

这是我的控制器:

public function transform() {
    include ('includes/vendor/autoload.php');
}

还有我的/app/start/global.php文件:

ClassLoader::addDirectories(array(
    app_path().'/commands',
    app_path().'/controllers',
    app_path().'/models',
    app_path().'/database/seeds',
    app_path().'/includes',

));

这是错误:

include(includes/vendor/autoload.php): failed to open stream: No such file or directory

您可以在app目录中的某个位置创建新目录,例如, app/libraries

然后在您的composer.json文件中,您可以包含app/libraries在自动加载类图中:

{
    "name": "laravel/laravel",
    "description": "The Laravel Framework.",
    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "require": {
        "laravel/framework": "4.2.*",
    },
    "autoload": {
        "classmap": [
            "app/commands",
            "app/controllers",
            "app/models",
            "app/libraries", <------------------ YOUR CUSTOM DIRECTORY
            "app/database/migrations",
            "app/database/seeds",
            "app/tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-install-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "php artisan clear-compiled",
            "php artisan optimize"
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ]
    },
    "config": {
        "preferred-install": "dist"
    },
    "minimum-stability": "stable",
}

确保composer dump-autoload在修改composer.json之后运行.

假设你的类名被调用CustomClass.php,它位于app/libraries目录中(所以完整的路径是app/libraries/CustomClass.php).如果按照惯例对类进行了正确命名,则可能会命名您的命名空间libraries.为了清楚起见,我们将调用我们的命名空间custom以避免与目录混淆.

$class = new \custom\CustomClass();

或者,您可以在app/config/app.php文件中为其指定别名:

/*
|--------------------------------------------------------------------------
| Class Aliases
|--------------------------------------------------------------------------
|
| This array of class aliases will be registered when this application
| is started. However, feel free to register as many as you wish as
| the aliases are "lazy" loaded so they don't hinder performance.
|
*/

'aliases' => array(
    ...
    'CustomClass'   => 'custom\CustomClass',
    ...
)

您可以像应用任何其他类一样在应用程序的任何位置实例化该类:

$class = new CustomClass();

希望这可以帮助!

我认为你是对的兄弟,但是,我找到了另一种方式,也许不是正确的方式,但它有效.

就像这样,我创建了一个名为Includes的新文件夹并将我的文件放在那里,然后在/app/start/global.php中添加了这一行:

require app_path().'/includes/vendor/autoload.php';

现在正在努力:D
