我试图创建一个Packagist / Composer包,用于一些训练,如果名称空间和作曲家。我无法弄清楚如何允许vendor/autoload.php
进行自动加载。
可在此处查看实际代码:https://github.com/ThomasKasper/Passthrough
或以下示例。
这是我的文件结构:
root
|---composer.json
|---src
|----Passthrough
|----Folder1
|SomeClass.php
|----Folder2
|----Folder3
|----Folder4
composer.json:
{
"name": "passthrough/passthrough",
"description": "A simple MVC framework",
"license": "MIT",
"keywords": ["passthrough", "framework"],
"require": {
"php": ">=5.3.0"
},
"autoload": {
"psr-4": {
"Passthrough\\": "src/Passthrough"
}
},
"autoload-dev": {
"psr-4": {
"Passthrough\\": "src/Passthrough"
}
}
}
示例类:
<?php
namespace Passthrough\Folder1;
class SomeClass
{
}
App.php
require 'vendor/autoload.php';
use Passthrough\Folder1\SomeClass;
$route = new SomeClass();
var_dump($route);
Fatal error: Class 'Passthrough\Folder1\SomeClass' not found in C:\wamp\www\PassthroughTester\app.php on line 7
答案 0 :(得分:0)
由于您的示例脚本没有失败,包括vendor/autoload.php
,我们可以放心地假设您确实已经运行
$ composer dump-autoload
但是,如果您在运行上述命令后修改了自动加载配置,那么这可能就是无法找到该类的原因。
此外,假设已正确设置自动加载,则脚本失败的唯一原因可能是Passthrough\Folder1\SomeClass
中的src/Passthrough/Folder1/SomeClass.php
类不存在,自动加载器实际上正在寻找它
猜测,从您的示例脚本和到您的存储库的链接,该示例实际上可能如下所示:
require 'vendor/autoload.php';
use Passthrough\Routing\Route\Route;
$route = new Route('foo', function () {
// . . .
});
var_dump($route);
然后输出是这样的:
PHP Fatal error: Class 'Passthrough\Base\Data\Callback' not found in /Users/am/Sites/stackoverflow/34509692/src/Passthrough/Routing/Route/Route.php on line 92
PHP Stack trace:
PHP 1. {main}() /Users/am/Sites/stackoverflow/34509692/app.php:0
PHP 2. Passthrough\Routing\Route\Route->__construct() /Users/am/Sites/stackoverflow/34509692/app.php:7
Fatal error: Class 'Passthrough\Base\Data\Callback' not found in /Users/am/Sites/stackoverflow/34509692/src/Passthrough/Routing/Route/Route.php on line 92
原因是Passthrough\Routing\Route\Route::__construct()
中引用的课程Passthrough\Base\Data\Callback
实际上并不存在于您的项目中。
与您的问题无关,但为开发和非开发环境设置相同的自动加载没有意义,您应相应调整composer.json
并删除autoload-dev
部分:
{
"name": "passthrough/passthrough",
"description": "A simple MVC framework",
"license": "MIT",
"keywords": ["passthrough", "framework"],
"require": {
"php": ">=5.3.0"
},
"autoload": {
"psr-4": {
"Passthrough\\": "src/Passthrough"
}
}
}
