nginx配置允许跨域请求
http {......
add_header Access-Control-Allow-Origin *;
add_header Access-Control-Allow-Headers X-Requested-With;
add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
......
}
或者
http {
if ($http_origin ~ https://xxx.com) {
add_header 'Access-Control-Allow-Origin' "$http_origin";
add_header 'Access-Control-Allow-Credentials' "true";
add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
}
....
}
这样就可以实现GET,POST,OPTIONS的跨域请求的支持
也可以 add_header Access-Control-Allow-Origin http://xxx.com; --指定允许的url;
