nginx配置支持跨域

将下面的一段配置放入项目的nginx配置文件的location区域里面；

location ~ \.php($|/) {
	#满足规则的域名判断
	if ($http_origin ~* "^https?://[a-z0-9]+\.domain\.com$" ) {
      	add_header access-control-allow-credentials true always;
        add_header access-control-allow-headers 'Authorization, x-requested-with, Content-Type' always;
        add_header access-control-allow-methods 'OPTIONS, GET, POST, PUT, PATCH, DELETE' always;
        add_header access-control-allow-origin $http_origin always;
	}
	#...
}
