ブラウザで報告される最初のエラーは権限の問題で、実際の問題はシェルでの 2 番目のエラーの実行です。プロンプトに従い、brew を使用して gpg-agent をインストールします。

その後、次のようにコードを書きました:

<code><span>require_once</span><span>'./Crypt/GPG.php'</span>;

<span>$gpg</span> = <span>new</span> Crypt_GPG();
<span>$key</span> = getKey();
<span>$gpg</span>->addDecryptKey(<span>'zhangsanfeng'</span>,<span>'123456'</span>);
<span>$encrypted</span> = file_get_contents(<span>'wait_for_decrpyt.txt.gpg'</span>);
<span>$data</span> = <span>$gpg</span>->decrypt(<span>$encrypted</span>);
<span>echo</span><span>'<pre class="brush:php;toolbar:false">'</span>;var_dump(<span>$data</span>);<span>exit</span>;</code>
