Php 如何在laravel中使用psr-0添加外部类

我正在laravel为Amaezone S3服务添加我自己的类。 这是我的作曲文件

"psr-0":{"App\\": "app/src/"}

我已在

app/src/app

并将amezone的所有lib放入此目录中

现在创建一个类

Amezones3.php

，并放入一些我自己的代码，在这个类中我想添加一个类，它是Amezones3服务类

在class

Amezones3.php中，我的构造函数如下

<?php namespace App;

class Amezones3 extends \BaseController{


/**
 *  Decalare Bucket Variable for S3
 *  default public
 */
public $bucketName;



/**
 *  Decalare Filename Variable for S3,this file name goes on the S3 server
 *  default public
 */
public $fileName;

/**
 *  Decalare Amezone S3 Object
 *  default public
 */
public $amazones3Obj;


/**
 *  Construct Fucntion for creating object of the AmezoneS3 Object
 *  Assign the created Object to @amazones3Obj variable
 *  @include the 'sdk.class.php' which is amezone PHP SDK for Serveice S3

 */

    require_once __DIR__.'/sdk.class.php';

    if($deletebukets){

    }else{

    }

但是当我运行页面时，会出现错误

Symfony \ Component \ Debug \ Exception \ FatalErrorException
"Class 'App\AmazonS3' not found"

我正在关注这段视频，它在这里运行良好

http://philsturgeon.co.uk/blog/2014/01/autoloading-laravel-application-code-with-psr4

注意：每件事都很好，但当我试图将一个类包含到ctructor中时，它将不起作用

请帮忙

提前谢谢。

您需要教授PHP AmazonS3名称空间：

<?php namespace App;

use The\Namespace\Of\Your\Class\AmazonS3; // <---- add a USE clause to do that

class Amezones3 extends \BaseController{


    /**
     *  Decalare Bucket Variable for S3
     *  default public
     */
    public $bucketName;

    ...

}

或者，您可以直接在线执行：

public function __construct()
{
    require_once __DIR__.'/sdk.class.php';

    $s3 = new The\Namespace\Of\Your\Class\AmazonS3();

    $this->amazones3Obj=$s3;

    pr($this->amazones3Obj);
}

$s3 = new AmazonS3();

public function __construct()
{
    require_once __DIR__.'/sdk.class.php';

    $s3 = new The\Namespace\Of\Your\Class\AmazonS3();

    $this->amazones3Obj=$s3;

    pr($this->amazones3Obj);
}
