PHP を使って効率的で安全な FTP サーバーを実装する (2)
前回の記事からの続きです。
1. ユーザークラス CUser を実装します。
ユーザーはテキスト形式で保存され、ユーザー配列は json でエンコードされます。
<span style="color: #000000;">用户文件格式： </span>* <span style="color: #0000ff;">array</span><span style="color: #000000;">( </span>* 'user1' => <span style="color: #0000ff;">array</span><span style="color: #000000;">( </span>* 'pass'=>'', * 'group'=>'', * 'home'=>'/home/ftp/', <span style="color: #008000;">//</span><span style="color: #008000;">ftp主目录</span> * 'active'=><span style="color: #0000ff;">true</span>, * 'expired=>'2015-12-12'<span style="color: #000000;">, * </span>'description'=>''<span style="color: #000000;">, * </span>'email' => ''<span style="color: #000000;">, * </span>'folder'<span style="color: #000000;">=>array( * //可以列出主目录下的文件和目录，但不能创建和删除，也不能进入主目录下的目录 * //前1-5位是文件权限，6-9是文件夹权限,10是否继承(inherit) * array(</span>'path'=>'/home/ftp/','access'=>'RWANDLCNDI'<span style="color: #000000;">), * //可以列出/home/ftp/a/下的文件和目录,可以创建和删除，可以进入/home/ftp/a/下的子目录，可以创建和删除。 * array(</span>'path'=>'/home/ftp/a/','access'=>'RWAND-----'<span style="color: #000000;">), * ), * </span>'ip'<span style="color: #000000;">=>array( * </span>'allow'<span style="color: #000000;">=>array(ip1,ip2,...),//支持*通配符: 192.168.0.* * </span>'deny'<span style="color: #000000;">=>array(ip1,ip2,...) * ) * ) * ) * * 组文件格式： * array( * </span>'group1'<span style="color: #000000;">=>array( * </span>'home'=>'/home/ftp/dept1/'<span style="color: #000000;">, * </span>'folder'<span style="color: #000000;">=>array( * * ), * </span>'ip'<span style="color: #000000;">=>array( * </span>'allow'<span style="color: #000000;">=>array(ip1,ip2,...), * </span>'deny'<span style="color: #000000;">=>array(ip1,ip2,...) * ) * ) * )</span>
フォルダーとファイルのアクセス許可の説明:
* 文件权限 * R读 : 允许用户读取（即下载）文件。该权限不允许用户列出目录内容，执行该操作需要列表权限。 * W写: 允许用户写入（即上传）文件。该权限不允许用户修改现有的文件，执行该操作需要追加权限。 * A追加: 允许用户向现有文件中追加数据。该权限通常用于使用户能够对部分上传的文件进行续传。 * N重命名: 允许用户重命名现有的文件。 * D删除: 允许用户删除文件。 * * 目录权限 * L列表: 允许用户列出目录中包含的文件。 * C创建: 允许用户在目录中新建子目录。 * N重命名: 允许用户在目录中重命名现有子目录。 * D删除: 允许用户在目录中删除现有子目录。注意： 如果目录包含文件，用户要删除目录还需要具有删除文件权限。 * * 子目录权限 * I继承: 允许所有子目录继承其父目录具有的相同权限。继承权限适用于大多数情况，但是如果访问必须受限于子文件夹，例如实施强制访问控制（Mandatory Access Control）时，则取消继承并为文件夹逐一授予权限。 *
実装コードは以下の通り：
