PowerShell:循环访问 .ini 文件

[英]PowerShell: Looping through an .ini file

I'm working on a PowerShell script that will do the following:我正在编写一个 PowerShell 脚本,它将执行以下操作:

  1. Use a function to grab the ini data and assign it to a hashtable (basically what Get-IniContent does, but I'm using one I found on this site).使用一个函数来获取 ini 数据并将其分配给一个哈希表(基本上是 Get-IniContent 所做的,但我正在使用我在这个站点上找到的一个)。
  2. Check the nested keys (not the sections, but the keys of each section) to see if the value "NoRequest" exists.检查嵌套键(不是部分,而是每个部分的键)以查看值“NoRequest”是否存在。
  3. If a section contains a NoRequest key, and ONLY IF the NoRequest value is false, then I want to return the name of the section, the NoRequest key, and the key's value.如果某个部分包含 NoRequest 键,并且仅当 NoRequest 值为 false,那么我想返回该部分的名称、NoRequest 键和键的值。 For example, something like "Section [DataStuff] has a NoRequest value set to false."例如,“Section [DataStuff] 的 NoRequest 值设置为 false”。 If a section doesn't contain a NoRequest key, or the value is set to true, then it can be skipped.如果某个部分不包含 NoRequest 键,或者该值设置为 true,则可以跳过它。

I believe I've accomplished the first two parts of this, but I'm unsure of how to proceed with the third step.我相信我已经完成了前两部分,但我不确定如何进行第三步。 Here's the code I have so far:这是我到目前为止的代码:

function Get-IniFile 
{  
    param(  
        [parameter(Mandatory = $true)] [string] $filePath  
    )  

    $anonymous = "NoSection"

    $ini = @{}  
    switch -regex -file $filePath  
    {  
        "^\[(.+)\]$" # Section  
        {  
            $section = $matches[1]  
            $ini[$section] = @{}  
            $CommentCount = 0  
        }  

        "^(;.*)$" # Comment  
        {  
            if (!($section))  
            {  
                $section = $anonymous  
                $ini[$section] = @{}  
            }  
            $value = $matches[1]  
            $CommentCount = $CommentCount + 1  
            $name = "Comment" + $CommentCount  
            $ini[$section][$name] = $value  
        }   

        "(.+?)\s*=\s*(.*)" # Key  
        {  
            if (!($section))  
            {  
                $section = $anonymous  
                $ini[$section] = @{}  
            }  
            $name,$value = $matches[1..2]  
            $ini[$section][$name] = $value  
        }  
    }  

    return $ini  
}  

$iniContents = Get-IniFile C:\testing.ini

    foreach ($key in $iniContents.Keys){
    if ($iniContents.$key.Contains("NoRequest")){
        if ($iniContents.$key.NoRequest -ne "true"){
        Write-Output $iniContents.$key.NoRequest
        }
    }
}

When I run the run the above code, it gives me the following expected output, since I know there are four instance of NoRequest in the INI and only one of them is set to false:当我运行上面的代码时,它给了我以下预期的输出,因为我知道 INI 中有四个 NoRequest 实例,其中只有一个设置为 false:

false

I believe I've solved the problem of finding the correct value(s) from the file, but I'm unsure of how to proceed with getting the correct output as mentioned in step 3 above.我相信我已经解决了从文件中找到正确值的问题,但我不确定如何继续获得上面步骤 3 中提到的正确输出。

You were almost there.你快到了。 This will output a string in the form you mentioned:这将以您提到的形式输出一个字符串:

$key = "NoRequest" # They key you're looking for
$expected = "false" # The expected value
foreach ($section in $iniContents.Keys) {
    # check if key exists and is set to expected value
    if ($iniContents[$section].Contains($key) -and $iniContents[$section][$key] -eq $expected) {
        # output section-name, key-name and expected value
        "Section '$section' has a '$key' key set to '$expected'."
    }
}

Of course, since you said..当然,既然你说..

If a section contains a NoRequest key, and ONLY IF the NoRequest value is false, then I want to return the name of the section, the NoRequest key, and the key's value.如果某个部分包含 NoRequest 键,并且仅当 NoRequest 值为 false,那么我想返回该部分的名称、NoRequest 键和键的值。

.. the key-name and -value will always be the same in the output. .. key-name 和 -value 在输出中总是相同的。
