Question

我有composer.json文件：

{
    "name": "marko/art-empire",
    "description": "Social network",
    "type": "project",
    "authors": [
        {
            "name": "Marko Ilic",
            "email": "markowebdeveloper@gmail.com"
        }
    ],
    "require": {},
    "autoload": {
      "psr-4": {
        "Songs\\": "songs/"
      }
    }
}

autoload_psr4.php文件：

$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);

return array(
    'Songs\\' => array($baseDir . '/songs'),
);

歌曲文件夹（位于根目录中）中的RandomSong.php文件：

namespace Song;

class RandomSong
{
    public function songName()
    {
        return 'Random Song';
    }
}

test.php文件：

require 'vendor/autoload.php';

use Songs\RandomSong;

$randomSong = new RandomSong();
echo $randomSong->songName();

如您所见，我正在尝试自动加载RandomSong类，但我一直在获取：

Fatal error: Uncaught Error: Class 'Songs\RandomSong' not found in test.php

请帮助，谢谢。

Answer 1

您的命名空间称为{"error":{"code":"UnsupportedApiVersion","message":"The HTTP resource that matches the request URI 'http://localhost:27713/api/v1.0/vt' does not support the API version '1.0'.","innerError":null}}，但您将其称为Song

Answer 2

您的RandomSong使用Song命名空间，而您的加载程序用于Songs命名空间。

Composer PSR-4自动加载完全被忽略
