PowerShell script - Extract, Copy and delete zip file not working

问题

# 创建 Java 版本目录，如果不存在的话，位于 C:\Users\$env:UserName\test\java

if (-not (Test-Path $Folder)) {
    try {
        New-Item -Path $Folder -ItemType Directory -ErrorAction Stop | Out-Null
    }
    catch {
        Write-Error -Message "无法创建目录 'C:\Program Files\test'。错误信息: $_" -ErrorAction Stop
    }
}

# 从内网下载文本文件
Invoke-WebRequest http://10.1.48.25/test/version.txt -OutFile "C:\Users\$env:UserName\test\java\version.txt"

# 从 version.txt 文件中检查 Java 版本
If (Get-Content $IntranetTextFile | %{$_ -match $JavaVersion}) {
    echo "版本相同"
}
else {
    # 下载 Java 文件
    Invoke-WebRequest $JavaDownloadPath -OutFile $JavaZipFilePath
}

# 在 C:\Users\$env:UserName\test\java\jdk-11.0.6 中解压缩 zip 文件
if (-not (Test-Path "C:\Users\$env:UserName\test\java\jdk-11")) {
    Expand-Archive "C:\Users\$env:UserName\test\java\openjdk-11+28_windows-x64_bin.zip" -DestinationPath "C:\Users\$env:UserName\test\java"
}

# 将 JDK zip 文件复制到 C:\Program Files\Java
Copy-Item -Path .\*.zip -Destination $ExpandArchiveDestinationPath -Force

# 在解压缩后删除 zip 文件
Remove-Item $JavaZipFilePath -Force

问题：

  1. 当 Java 版本相同时，脚本会下载 Java zip 文件，但实际上我不想要这个行为！
    目标是检查版本是否相同，如果相同，则显示 "相同版本"；如果不同，则下载 zip 文件。

  2. 当版本不同时，脚本没有执行解压缩、复制和删除操作。
    我对 PowerShell 完全不熟悉，请问如何解决上述问题？

  1. when java version is same above script is downloading java zip file which I didn't want!

  1. When version not same it is not extracting the zip file, not copying the file and not deleting it.

如果无论如何都在下载，那么验证功能未按预期运行。

我进行了一些更改，如您所见，一些语法修复等。

然而，当然，我无法测试这个，因为我不知道您的$IntranetTextFile中有什么，也没有类似的环境可以进行检查。

$JavaVersion                  = 'java.version=11.0.6'
$Folder                       = "C:\Users\$env:UserName\test\java"
$IntranetUrl                  = 'http://10.1.48.25/test/version.txt'
$IntranetTextFile             = "C:\Users\$env:UserName\test\java\version.txt"
$JavaDownloadPath             = 'http://10.1.48.25/test/install/Inst_20.05.00.01/testDesktop/OpenJDK11U-jdk_x64_windows_hotspot_11.0.6_10.zip'
$JavaZipFilePath              = "C:\Users\$env:UserName\test\java\openjdk-11+28_windows-x64_bin.zip"
$ExpandArchivePath            = "C:\Users\$env:UserName\test\java\*.zip"
$ExpandArchiveDestinationPath = "C:\Users\$env:UserName\test\java"

# 如果不存在，则在C:\Users\$env:UserName\test\java中创建java版本目录

if (-not (Test-Path $Folder)) 
{
    try 
    {
        New-Item -Path $Folder -ItemType Directory -ErrorAction Stop | 
        Out-Null #-Force
    }
    catch 
    {
        $WriteErrorSplat = @{
            Message     = "无法创建目录C:\Program Files\$Folder。错误是：$_"
            ErrorAction = 'Stop'
        }
        Write-Error @WriteErrorSplat
    }
} 

# 从内部下载文本文件
$InvokeWebRequestSplat = @{
    Uri     = 'http://10.1.48.25/test/version.txt'
    OutFile = "C:\Users\$env:UserName\test\java\version.txt"
}
Invoke-WebRequest @InvokeWebRequestSplat

# 检查version.txt中的java版本
如果 ((Get-Content $IntranetTextFile) -match $JavaVersion) 
{Write-Warning -Message 'Java版本已存在。不需要下载。'}
else {Invoke-WebRequest $JavaDownloadPath -OutFile $JavaZipFilePath}

# 在C:\Users\$env:UserName\test\java\jdk-11.0.6中提取zip文件

if (-not (Test-Path "C:\Users\$env:UserName\test\java\jdk-11")) 
{
    $ExpandArchiveSplat = @{
        Path            = "C:\Users\$env:UserName\test\java\openjdk-11+28_windows-x64_bin.zip" 
        DestinationPath = "C:\Users\$env:UserName\test\java"
    }
}
Expand-Archive @ExpandArchiveSplat

# 将JDK zip文件复制到C:\Program Files\Java
Copy-Item -Path '.\*.zip' -Destination $ExpandArchiveDestinationPath -force

# 提取后删除zip文件
Remove-Item $JavaZipFilePath -Force

If it is downloading anyway, then the validation is not functioning as expected.

I made a few changes, as you can see, some syntax fixups, etc.

Yet, of course, I can't test this as I don't know what is in your $IntranetTextFile, nor do I have a similar environment to check against.

$JavaVersion                  = 'java.version=11.0.6'
$Folder                       = "C:\Users\$env:UserName\test\java"
$IntranetUrl                  = 'http://10.1.48.25/test/version.txt'
$IntranetTextFile             = "C:\Users\$env:UserName\test\java\version.txt"
$JavaDownloadPath             = 'http://10.1.48.25/test/install/Inst_20.05.00.01/testDesktop/OpenJDK11U-jdk_x64_windows_hotspot_11.0.6_10.zip'
$JavaZipFilePath              = "C:\Users\$env:UserName\test\java\openjdk-11+28_windows-x64_bin.zip"
$ExpandArchivePath            = "C:\Users\$env:UserName\test\java\*.zip"
$ExpandArchiveDestinationPath = "C:\Users\$env:UserName\test\java"

# create java version directory in C:\Users\$env:UserName\test\java if it does not exist

if (-not (Test-Path $Folder)) 
{
    try 
    {
        New-Item -Path $Folder -ItemType Directory -ErrorAction Stop | 
        Out-Null #-Force
    }
    catch 
    {
        $WriteErrorSplat = @{
            Message     = "Unable to create directory C:\Program Files\$Folder. Error was: $_"
            ErrorAction = 'Stop'
        }
        Write-Error @WriteErrorSplat
    }
} 

# Download text file from intranet 
$InvokeWebRequestSplat = @{
    Uri     = 'http://10.1.48.25/test/version.txt'
    OutFile = "C:\Users\$env:UserName\test\java\version.txt"
}
Invoke-WebRequest @InvokeWebRequestSplat

# Check java version from version.txt
If ((Get-Content $IntranetTextFile) -match $JavaVersion) 
{Write-Warning -Message 'Java Version already exits. Download not needed.'}
else {Invoke-WebRequest $JavaDownloadPath -OutFile $JavaZipFilePath}

#Extract the zip file in C:\Users\$env:UserName\test\java\jdk-11.0.6

if (-not (Test-Path "C:\Users\$env:UserName\test\java\jdk-11"))

        DestinationPath = "C:\Users\$env:UserName\test\java"
    }
}
Expand-Archive @ExpandArchiveSplat

# Copy the JDK zip file to C:\Program Files\Java
Copy-Item -Path '.\*.zip' -Destination $ExpandArchiveDestinationPath -force

#Delete the zip file after extraction
Remove-Item $JavaZipFilePath -Force
