在開發的時候，需要把依賴的服務更新到最新，然後 手動composer update一下，提示如下：

 1 failed)    Update failed (The "e "https://api.github.com/repos/illuminate/validation/zipball/6590d61858f78c301bced7308593abfcd1c7e527" fi" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:

 5     Would you like to try reinstalling the package instead [yes]? no

如下圖所示：

其實主要就是提示：

file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO

經過排查，發現composer.json裡面的“config”項中的"secure-http": false 意思就是禁用了https請求：

於是將這個配置項改為true，然後重新composer update依賴，成功解決了這個問題！
