nginx支持跨域访问资源

server {
listen 80;
server_name localhost;

location /static {
   root /var/www/webpage;
   expires 30d;
   add_header Cache-Control public;
   access_log off;

   # 加入如下内容，即可允许跨域访问static资源
   add_header Access-Control-Allow-Origin $http_origin;
   add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
   add_header Access-Control-Allow-Credentials true;
