安装 ADFS 会抛出“空参数”
这是我用于安装 ADFS 的脚本的一部分。非常简单，但 Start-Process 似乎正在以一种有趣的方式解析开关。我有什么遗漏的吗？
write-host "Installing ADFS - process should take 30-45 seconds"
$installtime=get-date -uformat "%Y_%h_%d_%H_%M"
$logfile="$pwd\adfssetup_$installtime.log"
$ADFSInstall = "AdfsSetup.exe"
$ADFSInstallParams = '/quiet /logfile '+$logfile
Start-Process $ADFSInstall $ADFSInstallParams -wait
if ({gc -path $logfile | select-string -pattern "AD FS 2.0 is already installed on this computer"} -eq $null){write-host -ForegroundColor Cyan "ADFS Installed"} Else{write-host -ForegroundColor "There was an error Installing ADFS, please check the log file: $logfile;break}
如果我执行上述脚本，我会在日志文件中得到以下内容：
Microsoft.IdentityServer.Setup Error: 5124 : 6 [ 2070099085 ]: System.FormatException: Index (zero based) must be greater than or equal to zero and less than the size of the argument list. at System.Text.StringBuilder.AppendFormat(IFormatProvider provider, String format, Object[] args) at Microsoft.IdentityServer.Setup.Diagnostics.TraceLog.WriteLine(TraceEventType eventType, String msg, Object[] args)
如果我手动执行完全相同的命令（来自 write-host 的输出），则一切正常。
有什么想法吗？ 谢谢。
This is a portion of my script for installing ADFS. Pretty straightforward, but it seems Start-Process is parsing switches in a funny way. Is there something I'm missing?
write-host "Installing ADFS - process should take 30-45 seconds"
$installtime=get-date -uformat "%Y_%h_%d_%H_%M"
$logfile="$pwd\adfssetup_$installtime.log"
$ADFSInstall = "AdfsSetup.exe"
$ADFSInstallParams = '/quiet /logfile '+$logfile
Start-Process $ADFSInstall $ADFSInstallParams -wait
if ({gc -path $logfile | select-string -pattern "AD FS 2.0 is already installed on this computer"} -eq $null){write-host -ForegroundColor Cyan "ADFS Installed"} Else{write-host -ForegroundColor "There was an error Installing ADFS, please check the log file: $logfile;break}
If I Execute the above script I get the following in a log file:
Microsoft.IdentityServer.Setup Error: 5124 : 6 [ 2070099085 ]: System.FormatException: Index (zero based) must be greater than or equal to zero and less than the size of the argument list. at System.Text.StringBuilder.AppendFormat(IFormatProvider provider, String format, Object[] args) at Microsoft.IdentityServer.Setup.Diagnostics.TraceLog.WriteLine(TraceEventType eventType, String msg, Object[] args)
If I execute the exact same command manually (from the output of write-host), everything works fine.
Any ideas?
Thank you.

我无法删除这个问题，但通过调查较旧的日志发现，即使我以常规方式运行命令，也会发生错误。所以上面的脚本实际上是按预期工作的。
I cant delete the question, but what I found by investigating older logs is that the error occurs even when I run the command the regular way. So the above script is actually working as intended.
（我不太明白这里发生了什么，但有两种可能性。）
一种选择是您的
get-date无法按您的预期工作。结果是$logfile包含百分号 (%)，这会导致 AD FS 2.0 安装程序中出现“格式字符串注入”。错误消息指向该方向。但是，如果我在自己的系统上运行您的 PowerShell 脚本，我将无法重现该情况。
另请注意，您似乎在一个参数中传递了三个命令行参数（
/quiet、/logfile和日志文件名）。尝试像这样传递它们：但是，如果这是问题的原因，那么我预计
adfssetup.exe会抱怨类似command line argument '/quiet /logfile .. .' 无法识别。(I don't really understand what is happening here, but here are two possibilities.)
One option is that your
get-datedoes not work as you intend. The result is that$logfilecontains a percent sign (%), which causes 'format string injection' in the AD FS 2.0 installer. The error message points in that direction.However, I cannot reproduce that if I run your PowerShell script on my own system.
Also note that it looks like you're passing three command line arguments (
/quiet,/logfile, and the log file name) in one argument. Try passing them like so:However, if this were the cause of the problem then I would have expected
adfssetup.exeto complain with an error likecommand line argument '/quiet /logfile ...' not recognized.
