调试Crypt_GPG的过程

在浏览器端的错误输出信息：

命令行输出的错误信息：

第一个browser中报的错我分析是权限问题，第二个在shell中运行才是其真正的问题所在，根据提示，使用brew安装gpg-agent。

之后我编写代码如下：

<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">'

;var_dump($data);exit;

终于解密成功！！！
