在开发的时候，需要把依赖的服务更新到最新，然后 手动composer update一下，提示如下：
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:
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version
Failed to enable crypto
failed to open stream: operation failed)
Would you like to try reinstalling the package instead [yes]? no [Composer\Downloader\TransportException]
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:
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version
Failed to enable crypto
failed to open stream: oper
如下图所示：
其实主要就是提示：
file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO
经过排查，发现composer.json里面的“config”项中的"secure-http": false 意思就是禁用了https请求：
于是将这个配置项改为true，然后重新composer update依赖，成功解决了这个问题！
