关于App_Offline.htm的应用实例（及CIM_DataFile的用法）注意Windows下

App_Offline.htm的目的和意义是可以临时控制网页的应用界面显示与否，这里不再细说。微软为了控制页面，特地设置了此名专门处理屏蔽网页。

这两天，突然看到一个用VBS写的脚本语言如下（关键字段）追加App_Offline.htm代码。

Option Explicit

Dim objWbemLocator
Dim oIIS71
Dim fs
Dim f
Dim dwError
Dim nCopy

Const AP101_NAME = "192.168.131.37"
Const AP101_USER = "192.168.131.37Administrator"
Const AP101_PASS = "S3300859!"

Const AP101_FROM = "C:\inetpub\wwwroot\SWSK_NEW2\SWSK_Frame\SWSK_Frame\WebSite\WebFront\Offline.htm"
Const AP101_TO   = "C:\inetpub\wwwroot\SWSK_NEW2\SWSK_Frame\SWSK_Frame\WebSite\App_Offline.htm"


On Error Resume Next
Set objWbemLocator = CreateObject("WbemScripting.SWbemLocator")

Set oIIS71 = objwbemLocator.ConnectServer(AP101_NAME, "", AP101_USER, AP101_PASS)
If Err.Number <> 0 Then
    dwError = Err.Number
    WScript.Quit dwError
End If

nCopy = 0
Set fs = oIIS71.ExecQuery("Select * From CIM_DataFile Where Name = '" & AP101_FROM & "'") 
For Each f in fs
    dwError = f.Copy (AP101_TO) 
    nCopy = 1
    If dwError <> 0 And dwError <> 10 Then
        WScript.Quit dwError
    End If
    Exit For
Next
If nCopy = 0 Then
    WScript.Quit 1 'コピー元ファイルなし
End If

Set fs = Nothing
Set oIIS71 = Nothing
Set objWbemLocator = Nothing

　　

上述代码实现远程Web服务器的目录下追加App_Offline.htm文件，这样正在访问的操作者因为App_Offline.htm的原因，临时操作将会被切换到静态页面

App_Offline.htm中。

反过来，如果要恢复，将将该文件，删除即可。（其实，修改文件名也不失是一种好办法）

这里添加一段，用于删除App_Offline.htm的VBS脚本语言，供参考

Option Explicit

Dim objWbemLocator
Dim oIIS71
Dim fs
Dim f
Dim dwError

Const AP101_NAME = "192.168.131.37"
Const AP101_USER = "192.168.131.37Administrator"
Const AP101_PASS = "S3300859!"

Const AP101_TO = "C:\inetpub\wwwroot\SWSK_NEW2\SWSK_Frame\SWSK_Frame\WebSite\App_Offline.htm"


On Error Resume Next
Set objWbemLocator = CreateObject("WbemScripting.SWbemLocator")

Set oIIS71 = objwbemLocator.ConnectServer(AP101_NAME, "", AP101_USER, AP101_PASS)
If Err.Number <> 0 Then
dwError = Err.Number
WScript.Quit dwError
End If

Set fs = oIIS71.ExecQuery("Select * From CIM_DataFile Where Name = '" & AP101_TO & "'") 
For Each f in fs
dwError = f.Delete
If dwError <> 0 Then
WScript.Quit dwError
End If
Exit For
Next

Set fs = Nothing
Set oIIS71 = Nothing
Set objWbemLocator = Nothing
