FTP 7.5 自定义扩展功能
参考:
http://gzzhang.blog.51cto.com/5312382/1125092
随着IIS7的发布,IIS自带的FTP终于能自定义验证了.
目前知道的自定义接口共三个 自定义校验, 自定义主目录,自定义日志
分别是 Microsoft.Web.FtpServer的
IFtpAuthenticationProvider,
IFtpRoleProvider 主目录:
IFtpHomeDirectoryProvider 日志的没测试, 可以在WWW.IIS.NET直接找到的
步骤:
1. 首先创建 C#类库 (要选择 2.0 / 3.5 框架) ,有说 .NET 4.0不支持 ,但是这个没做验证,需要后期继续测试
2. 然后增加生成事件 后期处理 VS2012版本:
net stop ftpsvc
call "%VS110COMNTOOLS%\vsvars32.bat">null
gacutil.exe /if "$(TargetPath)"
net start ftpsvc VS2013 =vs120 ,其他版本递减
3. 添加签名(无密码)
4. 代码
namespace FtpHomeDirectory
{
public class FtpHomeDirDemo : BaseProvider,
IFtpHomeDirectoryProvider
{
string IFtpHomeDirectoryProvider.GetUserHomeDirectoryData(
string sessionId,
string siteName,
string userName)
{
// Note: You would add your own custom logic here.
// Return the user's home directory based on their user name.
string homedir = @" D:\Ftptest\ " + userName;
VASLog.WriteLog_day( @" d:\Ftptest ", " ftplog ", " siteName: " + siteName + " 用户想要得到的目录是: "+homedir+ " ; ");
return homedir;
}
}
{
public class FtpHomeDirDemo : BaseProvider,
IFtpHomeDirectoryProvider
{
string IFtpHomeDirectoryProvider.GetUserHomeDirectoryData(
string sessionId,
string siteName,
string userName)
{
// Note: You would add your own custom logic here.
// Return the user's home directory based on their user name.
string homedir = @" D:\Ftptest\ " + userName;
VASLog.WriteLog_day( @" d:\Ftptest ", " ftplog ", " siteName: " + siteName + " 用户想要得到的目录是: "+homedir+ " ; ");
return homedir;
}
}
}

尽量两个分开吧
生成后,在输出里可以看到
1>
1> Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.17929
1> 版权所有(C) Microsoft Corporation。保留所有权利。

1> 程序集已成功添加到缓存中
1> Microsoft FTP Service 服务正在启动 .
1> Microsoft FTP Service 服务已经启动成功。
然后要做的,就是配置IIS了
1. 在IIS的根基目录中,配置 FTP身份验证,禁用其他选项,在右侧自定义提供程序中,注册刚才的DLL,
2. FTP规则里,允许所有账户
3. 同样的注册主目录DLL
4. 跟密码验证不同,主目录的DLL,还需要设置两个地方
http://www.iis.net/learn/develop/developing-for-ftp/how-to-use-managed-code-c-to-create-a-simple-ftp-home-directory-providercd %systemroot%/system32/Inetsrv/
AppCmd set site "YourFTP" /+ftpServer.customFeatures.providers.[name='FtpHomeDirectoryDemo',enabled='true']
AppCmd set site "YourFTP" /ftpServer.userIsolation.mode:Custom
注意: 第一个appcmd 里面的 name = ftphomedirectorydemo 这个name,是在上面注册在IIS里的名称,跟DLL的空间类名没关系,一定要注意
禁用缓存，以管理员身份运行：
cd /d "%SystemRoot%\System32\Inetsrv"
Appcmd.exe set config -section:system.ftpServer/caching /credentialsCache.enabled:"False" /commit:apphost
这个一定要执行,不然,修改了数据库的密码之后,依然旧密码要保留一点时间,但是原因是什么,不理解.
现象,好像是登录时,直接就过了验证,进入到了目录获取的地方去了.
这样设置之后,才能启用主目录的设置
5. 在FTP用户隔离里,选择 下面的 用户名目录(禁用全局虚拟目录) ,这个用不用,还不知道,有待测试! 原理上考虑,这个其实没作用了,毕竟主目录在DLL里,已经可以定义了
