有时候composer install/update的时候会报错:[Composer\Downloader\TransportException] Your configuration does not allow connection to http://ooxx/xxoo.Git. See https://getcomposer.org/doc/06-config.md#secure-httpfor details.
解决方法是设置一个本地或全局的composer配置:
composer config secure-http false
全局设置: composer config -g secure-http false
意义是默认禁用https请求,就可以了
