如何将项目中的文件添加到Composer Classmap AutoLoad？

Question

这是我的项目的结构，

Answer 1

  {
  “自动加载”：{
    “ classmap”：[../ subproject2/classineed.php“]
  }
}
 

是否可以将项目文件添加到Composer AutoLoad ClassMap？

是的，要将项目文件列入Composer AutoLoad ClassMap中，您将其定义为项目（即在其自己的项目中），请使用其自动加载器，然后需要另一个项目。

然后，您将其放在那里。

subproject1/composer.json

{
  "name": "main/sub-1",
  "require": {
    "main/sub-2": "1.0.0"
  },
  "scripts": {
    "post-autoload-dump": [
      "@php -r 'require __DIR__ . \"/vendor/autoload.php\"; var_dump(class_exists(\"Foo\"));'"
    ]
  },
  "repositories": {
    "main/sub-2": {
      "type": "path",
      "url": "../subProject2",
      "options": {
        "versions": {
          "main/sub-2": "1.0.0"
        }
      }
    }
  }
}

subproject2/composer.json

{
  "name": "main/sub-2",
  "description": "File I need",
  "autoload": {
    "classmap": ["classINeed.php"]
  }
}

然后在 subproject1 中运行

$ rm -rf vendor && composer install
Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Package operations: 1 install, 0 updates, 0 removals
  - Installing main/sub-2 (1.0.0): Symlinking from ../subProject2
Generating autoload files
> @php -r 'require __DIR__ . "/vendor/autoload.php"; var_dump(class_exists("Foo"));'
Command line code:1:
bool(true)

非常感谢您的回答，但可悲的是，我在Subproject2

中没有作曲家

- 虽然不建议 - 当然可以提供该作曲家。

因此，另一个项目不得拥有作曲家。这是软件包存储库。

这里是一个扩展变体，此外还显示它：

subproject1/composer.json （ subproject2/not-composer-json hapem coposer .json 文件）

{
  "name": "main/sub-1",
  "require": {
    "main/sub-2-no-composer-json": "1.0.0"
  },
  "scripts": {
    "post-autoload-dump": [
      "# this time autoloader test with composer only",
      "classINeed::hasMagic__callStatic"
    ]
  },
  "repositories": {
    "packagist.org": false,
    "main/sub-2": {
      "type": "path",
      "url": "../subProject2",
      "options": {
        "versions": {
          "main/sub-2": "1.0.0"
        }
      }
    },
    "main/sub-2-no-composer-json": {
      "type": "package",
      "package": {
        "name": "main/sub-2-no-composer-json",
        "version": "1.0.0",
        "dist": {
          "type": "path",
          "url": "../subProject2/no-composer-json"
        },
        "autoload": {
          "classmap": ["classINeed.php"]
        }
      }
    }
  }
}

示例性运行：

$ composer install
Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Nothing to install, update or remove
Generating autoload files
> # this time autoloader test with composer only
> classINeed::hasMagic__callStatic
{
    "name": "hasMagic__callStatic",
    "argv": [
        "object Event: post-autoload-dump"
    ]
}

Answer 2

Composer \ autoload \ classLoader ::

$loader = require PROJECT_DIR . '/vendor/autoload.php';
var_dump($loader->getClassMap());
$loader->addClassMap(['MyClass' => '/path/to/class.php']);
var_dump(new MyClass());
