阿里云 Composer 全量镜像【下载速度超快，亲测~】
全局配置（推荐）
所有项目都会使用该镜像地址：
composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/取消配置：
composer config -g --unset repos.packagist项目配置
- 仅修改当前工程配置，仅当前工程可使用该镜像地址：
composer config repo.packagist composer https://mirrors.aliyun.com/composer/ - 取消配置：
composer config --unset repos.packagist
调试
- composer 命令增加 -vvv 可输出详细的信息，命令如下：
composer -vvv require alibabacloud/sdk
