之前用預設的composer配置，安裝了laravel，現在切換會國內鏡像，安裝一個三方包，就提示這個

[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 

網上的解決方案都不行，我嘗試多次，總是有這個錯誤，也在該加的地方加了

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

是不是證書問題，我需要到哪裡修改呢？
