“需要对象"在作业中使用 Set 时 [英] "Object required" when using Set in an assignment

问题描述

call main()
sub main()
    Dim scmd
    Set scmd = "c:windowssystem32cscript.exe //nologo c:s.vbs"
    createobject("wscript.shell").run scmd,0,false
end sub

它给了我错误:

需要对象:'[string: "c:windowssystem32"]' 代码 800A01A8

推荐答案

更新

由于不清楚，最好指出您的 Object Required 问题是由于这一行

As it's not clear feel it best to point out your Object Required issue is due to this line

Set scmd = "c:windowssystem32cscript.exe //nologo c:s.vbs"

这是因为需要一个对象，但您为其分配了一个字符串，通过删除 Set 您的代码将起作用(如 Ekkehard.Horner指出).

This is because an Object is expected but you are assigning it a string, by removing the Set your code will work (As Ekkehard.Horner has pointed out).

以下是我对情况的解释.首先查看您的代码，它几乎看起来像是将 WScript.Shell 对象的实例化与 .Run() 方法的命令行混合在一起.这是我第一次尝试分解代码，重新排列然后将其重新组合在一起.

Below is my interpretation of situation. First looking at your code it almost looked like it had mixed the instantiation of the WScript.Shell object with the command line for the .Run() method. It was my first stab at breaking down the code, rearranging it then putting it back together.

原答案

1. 您的 Set scmd 应该实例化 WScript.Shell(如 Ekkehard.Horner 指出您可以使用 Server.CreateObject("WScript.Shell").Run 作为一次性参考，但我不推荐它).

1. Your Set scmd should be instantiating the WScript.Shell (As Ekkehard.Horner points out you can use Server.CreateObject("WScript.Shell").Run for a one off reference but I wouldn't recommend it).

.Run()应该由实例化的scmd对象执行，并通过命令行执行.

The .Run() should be executed by the instantiated scmd object and passed the command line to execute.

这是一个示例，我已将一些变量重命名(例如 scmd 为 cmd).

Here is an example I've renamed some of the variables (scmd to cmd for example).

Call main()

Sub main()
    'Renamed variables to cmd is your object and cmdline is your file path.
    Dim cmd, cmdline
    'Instantiate WshShell object
    Set cmd = Server.Createobject("WScript.Shell")
    'Set cmdline variable to file path
    cmdline = "c:windowssystem32cscript.exe //nologo c:s.vbs"
    'Execute Run and return immediately
    Call cmd.Run(cmdline, 0, False)
End Sub

需要考虑的事项

在经典 ASP 中使用 WScript.Shell 运行可执行文件时，需要考虑一些事项；

When using WScript.Shell in Classic ASP to run executables there are some things to consider;

1. 运行命令将使用当前的应用程序池身份执行.

1. Run command will execute using the current Application Pool identity.

Run 将在服务器而不是客户端(服务器端)上执行可执行文件.

Run will execute the executable on the server not at the client (server side).
