Composer 失败

问题：

The "https://packagist.laravel-china.org/packages.json" file could not be downloaded: Peer certificate CN=*.phphub.org' did not match expected CN=packagist.laravel-china.org'
Failed to enable crypto
failed to open stream: operation failed
https://packagist.laravel-china.org could not be fully loaded, package information was loaded from the local cache and may be out of date

按说明是镜像地址请求出错，于是去https://packagist.laravel-china.org查看，发现Laravel China在一个月前发了篇文章《Laravel China 镜像完成历史使命，将于两个月后停用》，所以很明白了，你需要换镜像。

阿里云Composer全量镜像
Packagist 官方实时同步，推荐使用最新的 Composer 版本。

• 镜像类型：全量镜像
• 更新时间：1 分钟
• 镜像说明：阿里云 CDN 加速，更新速度快，推荐使用

全局配置（推荐）

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
