Access-Control-Allow-Origin ヘッダーの追加方法

Access-Control-Allow-Originとは:https://qiita.com/att55/items/2154a8aad8bf1409db2b

from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

ともかくJavascriptからデータをロードする際出てくる上記エラーの対処のためにサーバー側にAccess-Control-Allow-Origin ヘッダー追加する。

$ cd /var/www/html
#htaccessに書く
$ sudo nano .htaccess
Header set Access-Control-Allow-Origin "*"
#apache2のモジュール有効化
$ sudo a2enmod headers
#apache2再起動
$ systemctl restart apache2
