开发人员反馈：
No ‘Access-Control-Allow-Origin’ header is present on the requested resource
vi httpd.conf 取消如下注释#
LoadModule headers_module [...] 然后VirtualHost服务中添加 Header set Access-Control-Allow-Origin \"*\"
##全局配置如下
vi httpd.conf 最下面添加如下配置：
Header set Access-Control-Allow-Origin: \"*\"
Header set Access-Control-Allow-Methods: \"GET,POST,PUT,DELETE,OPTIONS\"
Header set Access-Control-Allow-Headers: \"Content-Type\"
