PowerShell调试调用命令

Question

我试图找到一个简单的方法来达到ScriptBlock的Invoke-Command。我已阅读Hey Scripting Guy博客，但他们只调用脚本文件，我对如何做到这一点感到困惑。

有人可以告诉我如何让调试器停止在线说$Var = 5？我试过Set-PSBreakpoint，但总是失败。这对于检查值和所有代码是否正确都很方便。

代码示例：

$session = New-PSSession -ComputerName localhost 

Invoke-Command -Session $session -ScriptBlock $LoadFunctions 

# Do other stuff 

Invoke-Command -Session $session -ScriptBlock { 

    $Time = Get-Date 
    $Var = '5' # Stop debugger here 

    Set-PSBreakpoint -Variable $Var 
} 

Remove-PSSession $Session 

谢谢您的帮助。

这是我的工作。顺便说一句，我在PowerShell 4.0中。

首先，我把设置psbreakpoint早些时候脚本块：

Invoke-Command -ComputerName . -ScriptBlock { 
    Set-PSBreakpoint -Variable metoo; 
    $test="foo"; 
    $one="1"; 
    $metoo="metoo"; 
} -Credential (Get-Credential) 

当我跑这我得到了以下信息：

WARNING: Session Session8 with instance ID 4a02c5f4-b333-4e58-85b7-78ccd4f31318 on computer localhost has been 
disconnected because the script running on the session has stopped at a breakpoint. Use the Enter-PSSession cmdlet on 
this session to connect back to the session and begin interactive debugging. 
WARNING: Session Session8 with instance ID 4a02c5f4-b333-4e58-85b7-78ccd4f31318 has been created for reconnection. 

所以看到会话还在那里，我做了一个Get-PSSession：

> Get-PSSession 

Id Name   ComputerName State   ConfigurationName  Availability 
-- ----   ------------ -----   -----------------  ------------ 
    9 Session8  localhost  Disconnected Microsoft.PowerShell   None 

太棒了，会议在那里，只需要重新连接并输入：

> Get-PSSession | Connect-PSSession 

Id Name   ComputerName State   ConfigurationName  Availability 
-- ----   ------------ -----   -----------------  ------------ 
    9 Session8  localhost  Opened  Microsoft.PowerShell RemoteDebug 

，并输入会议：

> Get-PSSession | Enter-PSSession 
WARNING: You have entered a session that is currently stopped at a debug breakpoint inside a running command or script. 
    Use the Windows PowerShell command line debugger to continue debugging. 
Entering debug mode. Use h or ? for help. 

Hit Variable breakpoint on ':$metoo' (Write access) 

At line:1 char:59 
+ Set-PSBreakpoint -Variable metoo; $test="foo"; $one="1"; $metoo="metoo"; 
+               ~ 
[localhost]: [DBG]: PS C:\Users\Foo\Documents>> 

大，所以现在我在我的远程调试会话！只要按照提示进行操作，如键入“H”的帮助或“K”来获得，psscallstack等

[localhost]: [DBG]: PS C:\Users\Foo\Documents>> h 

s, stepInto   Single step (step into functions, scripts, etc.) 
v, stepOver   Step to next statement (step over functions, scripts, etc.) 
o, stepOut   Step out of the current function, script, etc. 

c, continue   Continue operation 
q, quit    Stop operation and exit the debugger 

k, Get-PSCallStack Display call stack 

l, list    List source code for the current script. 
        Use "list" to start from the current line, "list <m>" 
        to start from line <m>, and "list <m> <n>" to list <n> 
        lines starting from line <m> 

<enter>    Repeat last command if it was stepInto, stepOver or list 

?, h    displays this help message.
