报错提示：getimagesize(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed
解决方案：
1、下载证书文件：https://curl.se/ca/cacert.pem
2、找到php.ini配置文件，搜索【curl.cainfo】和【openssl.cafile】，将内容更改如下：
curl.cainfo = /usr/local/openssl/cacert.pem openssl.cafile=/usr/local/openssl/cacert.pem
