-ErrorAction停止後腳本處理不會停止

Question

我正在編寫一個腳本，用於寫入並調用某些自己的函數。第一個功能我打電話是我記錄設置功能，在這裏我設置了這樣的日誌文件：

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 

如果該文件無法創建我想整個下面的腳本處理停止，但所有以下調用仍然處理。事件其他函數調用仍舊執行:(如果日誌文件創建失敗，我不想要任何東西去爲日誌文件是強制性的。

Answer 1

既然你捕獲try catch塊中的終止錯誤，則必須在write-host命令後添加終止語句。根據您的需要（例如，退出，中斷等）有多種選擇（例如，退出，中斷等）

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，您可以拋出自己的終止錯誤，如下所示：

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

Answer 2

你需要重新拋出錯誤..

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
