解決方法

• 應該是CA證書驗證失敗造成的錯誤，下載個CA證書

  [root@localhost ~]# wget http://curl.haxx.se/ca/cacert.pem
  [root@localhost ~]# mv cacert.pem /usr/local/openssl/ssl/certs/cacert.pem
  [root@localhost ~]# vim /yourpath/php.ini

• 修改cafile路徑，保存

  [openssl]
  ; The location of a Certificate Authority (CA) file on the local filesystem
  ; to use when verifying the identity of SSL/TLS peers. Most users should
  ; not specify a value for this directive as PHP will attempt to use the
  ; OS-managed cert stores in its absence. If specified, this value may still
  ; be overridden on a per-stream basis via the "cafile" SSL stream context
  ; option.
  ;openssl.cafile=
  openssl.cafile=/usr/local/openssl/ssl/certs/cacert.pem
