宝塔解决跨域的问题

宝塔的nginx配置里面加入：

    add_header Access-Control-Allow-Origin * always;
	add_header Access-Control-Allow-Methods GET,POST,DELETE; 
	add_header Access-Control-Allow-Header Content-Type,*;

最终效果：

server
{
    listen 80;
	listen 443 ssl http2;
    server_name jsyzmzdq.com *.uq728.cn uq728.cn;
    index index.php index.html index.htm default.php default.htm default.html;
    root /www/wwwroot/jsyzmzdq.com/public;
    add_header Access-Control-Allow-Origin * always;
    add_header Access-Control-Allow-Methods GET,POST,DELETE;  
    add_header Access-Control-Allow-Header Content-Type,*;
