composer 自動加載(php-amqplib)

最近要使用RabbitMQ 作消息隊列,也是剛接觸到.由於用的的TP框架,comoser又下載不下來,因此只能手動下載拓展包,作手動加載,在php-amqplib是我手動下載下來的拓展包,建立一個composer.json文件,在裏面輸入

38   },
39   "autoload": { 40     "psr-4": { 41       "PhpAmqpLib\\": "php-amqplib/PhpAmqpLib/"　　//主要是這裏,他是你加載包的路徑,PhpAmqpLib 是空間命名,遵循的是PSR-4 自動加載原則
42  } 43   },
44   "autoload-dev": { 45     "psr-4": { 46       "PhpAmqpLib\\Tests\\Functional\\": "tests/Functional",

52     "branch-alias": {

54     }
55   }
56 }

php composer.phar dump-autoload 就會生成一個vendor文件夾,使用的時候,你就只需把vendor文件夾裏的autoload.php 文件引入進去就能夠自動加載了
