1. nginx设置iframe页面跨域限制
可以使用 web 服务器配置来解决这个问题，在服务器端设置 X-Frame-Options 标头，以指示浏览器是否允许该页面在 iframe 中加载。还可以考虑使用 CORS（跨域资源共享）来解决跨域问题如2 .
X-Frame-Options: SAMEORIGIN
X-Frame-Options http响应头是用来给浏览器 指示允许一个页面可否在<frame>, <iframe>, <embed> 或者 <object> 中展现的标记, 可以通过确保网站没有被嵌入到别人的站点里，避免 clickjacking 攻击。
X-Frame-Options 语法:
# 该页面不允许在frame中展示，同域名页面中嵌套也不被允许
X-Frame-Options: deny
# 该页面可以在相同域名的页面的frame中展示
X-Frame-Options: sameorigin
# 该页面可以在指定来源的frame中展示
X-Frame-Options: allow-from https://example.com/

2. 设置 Nginx 解决跨域问题
可以使用 Nginx 的 add_header 指令设置相应的响应头来允许跨域请求,如下例子；
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
# 允许请求地址跨域 * 做为通配符
add_header 'Access-Control-Allow-Origin' '*';
# 允许跨域的请求方法
add_header 'Access-Control-Allow-Methods' 'GET, POST, PUT, DELETE, OPTIONS';
# 允许自定义的 'X-Custom-Header' 头部
add_header 'Access-Control-Allow-Headers' 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';
# 或者如下配置 设置基本的 CORS 处理器
if ($request_method = 'OPTIONS') {
# add_header 'Access-Control-Allow-Origin' '*';
# 配置基本的 CORS 处理器，允许指定域名跨域请求
# add_header 'Access-Control-Allow-Origin' 'http://example.com';
# add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
# add_header 'Access-Control-Allow-Headers' 'X-Requested-With,Content-Type,Authorization';
# add_header 'Access-Control-Max-Age' 1728000;
# add_header 'Content-Type' 'text/plain charset=UTF-8';
# add_header 'Content-Length' 0;
return 204;
}
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#

}
