之前用默认的composer配置，安装了laravel，现在切换会国内镜像，安装一个三方包，就提示这个

[Composer\Downloader\TransportException] The "https://packagist.phpcomposer.com/packages.json" file could not be downloaded: Peer certificate CN=`*.b0.upaiy un.com' did not match expected CN=`packagist.phpcomposer.com' Failed to enable crypto failed to open stream: operation failed

网上的解决方案都不行，我尝试多次，总有这个错误，也在该加的地方加了

"repositories": { "packagist": { "type": "composer", "url": "https://packagist.phpcomposer.com" } }

是不是证书问题，我需要到哪里修改呢？
