composer常用技巧集锦

1、增加公共函数

新建app/common.php文件

 function test(){}

composer.json新增如下配置

"autoload": {
        "classmap": [
            "database/seeds",
            "database/factories"
        ],
        "psr-4": {
            "App\\": "app/"
        },
        "files": [
            "app/common.php"
        ]
  },

执行命令

composer dump-autoload

2、回滚到1.*版本

composer self-update --1

3、升级到2.*版本

composer self-update --2

3、查看配置列表

composer config -l -g

4、配置国内镜像

composer config -g repos.packagist composer https://mirrors.cloud.tencent.com/composer/
