調試Crypt_GPG的過程

在瀏覽器端的錯誤輸出資訊：

( ! ) Fatal error: Uncaught <tablestyle="border: 1px"cellspacing="0"><tr><tdcolspan="3"style="background: #ff9999"><b>Crypt_GPG_FileExceptionb>: The 'homedir' "/Library/WebServer/.gnupg" is not readable or does not exist and cannot be created.

命令列輸出的錯誤資訊：

PHP Fatal error:  Uncaught PEAR_Exception: gpg-agent binary not found.If you are sure the gpg-agent is installed, please specify the location of the gpg-agent binary using the 'agent' driver option.in /usr/local/webdata/andy/fanli/citic/Crypt/GPGAbstract.php on line 278#0 /usr/local/webdata/andy/fanli/citic/Crypt/GPGAbstract.php(278): Crypt_GPG_Engine->__construct(Array)#1 /usr/local/webdata/andy/fanli/citic/gpg2.php(9): Crypt_GPGAbstract->__construct()#2 {main}  thrown in /usr/local/webdata/andy/fanli/citic/Crypt/GPG/Engine.php on line 601Fatal error: Uncaught PEAR_Exception: gpg-agent binary not found.If you are sure the gpg-agent is installed, please specify the location of the gpg-agent binary using the 'agent' driver option.in /usr/local/webdata/andy/fanli/citic/Crypt/GPGAbstract.php on line 278#0 /usr/local/webdata/andy/fanli/citic/Crypt/GPGAbstract.php(278): Crypt_GPG_Engine->__construct(Array)#1 /usr/local/webdata/andy/fanli/citic/gpg2.php(9): Crypt_GPGAbstract->__construct()#2 {main}  thrown in /usr/local/webdata/andy/fanli/citic/Crypt/GPG/Engine.php on line 601

第一個browser中報的錯我分析是許可權問題，第二個在shell中運行才是其真正的問題所在，根據提示，使用brew安裝gpg-agent。

之後我編寫代碼如下：

require_once'./Crypt/GPG.php';$gpg = new Crypt_GPG();$key = getKey();$gpg->addDecryptKey('zhangsanfeng','123456');$encrypted = file_get_contents('wait_for_decrpyt.txt.gpg');$data = $gpg->decrypt($encrypted);echo'
';var_dump($data);exit;
終於解密成功！！！
