-ErrorAction停止后脚本处理不会停止

Question

我正在编写一个脚本，用于写入并调用某些自己的函数。第一个功能我打电话是我记录设置功能，在这里我设置了这样的日志文件：

function Create-Logfile { 
    if (!(Test-Path $Path)) { 

     try { 
      Write-Verbose "Write-Log: Creating $Path" 
      $NewLogFile = New-Item $Path -Force -ItemType File -ErrorAction stop 
     } catch { 
      Write-Verbose "Write-Log: Creating $Path failed: $($error[0].Exception.Message)" 
     } 

    } 

    write-host 'i do still execute' 
} 

function Do-Something{ 
    write-host 'doing something' 
} 

Create-LogFile #create the file 
write-host 'processing didnt stop' 
Do-Something 

如果该文件无法创建我想整个下面的脚本处理停止，但所有以下调用仍然处理。事件其他函数调用仍旧执行:(如果日志文件创建失败，我不想要任何东西去为日志文件是强制性的。

Answer 1

既然你捕获try catch块中的终止错误，则必须在write-host命令后添加终止语句。根据您的需要（例如，退出，中断等）有多种选择（例如，退出，中断等）

例如：

try 
{ 
    Write-Verbose "Write-Log: Creating $Path" 
    $NewLogFile = New-Item $Path -Force -ItemType File -ErrorAction stop 
} 
catch 
{ 
    Write-Verbose "Write-Log: Creating $Path failed: $($error[0].Exception.Message)" 
    exit 
} 

或者，您可以抛出自己的终止错误，如下所示：

throw "Write-Log: Creating $Path failed: $($error[0].Exception.Message)" 

Answer 2

你需要重新抛出错误..

function Create-Logfile { 
    if (!(Test-Path $Path)) { 

     try { 
      Write-Verbose "Write-Log: Creating $Path" 
      $NewLogFile = New-Item $Path -Force -ItemType File -ErrorAction stop 
     } catch { 
      Write-Verbose "Write-Log: Creating $Path failed: $($error[0].Exception.Message)" 
      Throw 
     } 

    } 

    write-host 'i do still execute' 
} 

function Do-Something{ 
    write-host 'doing something' 
} 

Create-LogFile #create the file 
write-host 'processing didnt stop' 
Do-Something
