やりたいこと

Nginx で特定のパスにおいて固定のレスポンス (ステータスコード, ボディ) を返す.

諸注意

動作確認環境は以下の通り.

やったこと

こんな感じで設定を書いて /etc/nginx/conf.d/ 以下に置いた.

server {
    listen 80;
    server_name localhost;

    location ~ ^/(patha/aa/*|pathb/*|pathc/*)/ {
        default_type text/plan;
        return 400 'バッドリクエスト！！';
    }
(略)
}
