在项目下执行一下更新命令时报错：
composer update
[Composer\Exception\NoSslException]
The openssl extension is required for SSL/TLS protection but is not available. If you can not enable the openssl extension, you can disable this error, at your own risk, by setting the ‘disable-tls’ option to true. 
=======================
解决方法
进入php.ini 修改配置打开ssl
//将这行代码前的 ; 去掉 extension=php_openssl.dll
