這篇文章主要為大家詳細介紹了如何利用PowerShell一鍵下載Nuget某個包的所有版本,文中的示例代碼講解詳細,感興趣的小伙伴可以參考一下

一轉(zhuǎn)眼好幾年沒有寫博客了，來博客園冒個泡，最近由于工作需要，內(nèi)網(wǎng)辦公，幸運的是只需要上傳一個*.nupkg一個包信息就可以在私有nuget下載到了，下面就用PowerShell編寫下載腳本，需要注意的是PowerShell后綴ps1（最后一個數(shù)字1），以Newtonsoft.Json為例：

下載地址

# 設(shè)置NuGet包列表的URL
$packageName = "Newtonsoft.Json"
$targetHttp = "https://www.nuget.org/packages/"
$targetUrl = "{0}{1}" -f $targetHttp, $packageName

保存地址

# 設(shè)置保存已下載包的目錄
$outputDirectory = "D:\nuget_packages"
if (-not (Test-Path $outputDirectory)) {
    New-Item -Path $outputDirectory -ItemType Directory
}

解析下載版本地址

定義下載需要解析的包地址

# 定義下載前綴
$httpPrefix = "https://www.nuget.org/api/v2/package/"
# 下載html文件內(nèi)容
$htmlContent = Invoke-WebRequest -Uri $targetUrl -UseBasicParsing | Select-Object -ExpandProperty Content
# 匹配標簽
$pattern = "<.*?>"
$matches = [regex]::Matches($htmlContent, $pattern)

獲取所有a標簽

foreach ($match in $matches) {
　　$tag = $match.Value
　　# 獲取a標簽
　　if ($tag -like "<a href=*") {
　　　　Write-Host $tag
　　}
}

輸出結(jié)果

<a href="#" rel="external nofollow" rel="external nofollow" id="skipToContent" class="showOnFocus" title="Skip To Content">
...
<a href="/packages/System.Xml.XmlDocument/" rel="external nofollow" >
<a href="/packages/Newtonsoft.Json/13.0.3" rel="external nofollow" rel="external nofollow" title="13.0.3">
...
<a href="/packages/Newtonsoft.Json/3.5.8" rel="external nofollow" rel="external nofollow" title="3.5.8">
<a href="/stats/packages/Newtonsoft.Json?groupby=Version" rel="external nofollow" rel="external nofollow" title="Package Statistics">
...
<a href="/packages/Newtonsoft.Json/13.0.3/ReportAbuse" rel="external nofollow" rel="external nofollow" title="Report the package as abusive">
<a href="/packages/Newtonsoft.Json/13.0.3/ContactOwners" rel="external nofollow" rel="external nofollow" title="Ask the package owners a question">
...

觀察上一步結(jié)果可以看出來每一個版本都有title，且title內(nèi)容是版本

# 獲取含有title的a標簽
if ($tag -like "*title=*") {
  Write-Host $tag        
}

輸出結(jié)果

<a href="#" rel="external nofollow" rel="external nofollow" id="skipToContent" class="showOnFocus" title="Skip To Content">
<a href="/packages/Newtonsoft.Json/13.0.3" rel="external nofollow" rel="external nofollow" title="13.0.3">
...
<a href="/packages/Newtonsoft.Json/3.5.8" rel="external nofollow" rel="external nofollow" title="3.5.8">
<a href="/stats/packages/Newtonsoft.Json?groupby=Version" rel="external nofollow" rel="external nofollow" title="Package Statistics">
<a href="https://www.newtonsoft.com/json" rel="external nofollow" data-track="outbound-project-url" title="Visit the project site to learn more about this package" >
...
<a href="/packages/Newtonsoft.Json/13.0.3/ReportAbuse" rel="external nofollow" rel="external nofollow" title="Report the package as abusive">
<a href="/packages/Newtonsoft.Json/13.0.3/ContactOwners" rel="external nofollow" rel="external nofollow" title="Ask the package owners a question">
<a href="/packages?q=Tags%3A%22json%22" rel="external nofollow" title="Search for json" class="tag">

接著上一步的結(jié)果繼續(xù)過濾

# 截取href的內(nèi)容
$substr = $tag.Substring(9)
if ($substr -like "/packages/*") {
    Write-Host $substr
}

輸出結(jié)果

/packages/Newtonsoft.Json/13.0.3" title="13.0.3">
...
/packages/Newtonsoft.Json/3.5.8" title="3.5.8">
/packages/Newtonsoft.Json/13.0.3/ReportAbuse" title="Report the package as abusive">
/packages/Newtonsoft.Json/13.0.3/ContactOwners" title="Ask the package owners a question">

有完沒完，又來了？看上面的結(jié)果就還差過濾兩個不相關(guān)的了，

獲取href完整內(nèi)容

# 查找第一個雙引號的位置
$index = $substr.IndexOf('"')
# 獲取部分/packages/Newtonsoft.Json/13.0.3
$substr = $substr.Substring(0,$index)

剔除最后兩個版本無關(guān)的a標簽

# 排除報告濫用a標簽
if ($substr -notlike "*/ReportAbuse") {
　　# 排除聯(lián)系作者a標簽
　　if ($substr -notlike "*/ContactOwners") {
　　　　# 匹配版本
　　　　$endIndex = $substr.LastIndexOf('/')
　　　　$startPackageIndex = $endIndex + 1
　　　　$packageVersion = $substr.Substring($startPackageIndex)
　　}
}

Invoke-WebRequest命令下載并保存文件

# 下載地址nupkg
$packageUrl = "{0}{1}/{2}" -f $httpPrefix,$packageName,$packageVersion
# 生成保存文件的路徑
$packageFile = Join-Path -Path $outputDirectory -ChildPath "$packageName.$packageVersion.nupkg"
# 下載 .nupkg 文件
Write-Host "Downloading $packageName version $packageVersion from $packageUrl"
Invoke-WebRequest -Uri $packageUrl -OutFile $packageFile

全部代碼

# 設(shè)置NuGet包列表的URL
$packageName = "Newtonsoft.Json"
$targetHttp = "https://www.nuget.org/packages/"
$targetUrl = "{0}{1}" -f $targetHttp, $packageName
# 設(shè)置保存已下載包的目錄
$outputDirectory = "D:\nuget_packages"
if (-not (Test-Path $outputDirectory)) {
    New-Item -Path $outputDirectory -ItemType Directory
}
# 定義下載前綴
$httpPrefix = "https://www.nuget.org/api/v2/package/"
# 下載html文件內(nèi)容
$htmlContent = Invoke-WebRequest -Uri $targetUrl -UseBasicParsing | Select-Object -ExpandProperty Content
# 匹配標簽
$pattern = "<.*?>"
$matches = [regex]::Matches($htmlContent, $pattern)
foreach ($match in $matches) {
    $tag = $match.Value
        # 獲取a標簽
        if ($tag -like "<a href=*") {
            # 獲取含有title的a標簽
            if ($tag -like "*title=*")
            {
                # 截取href的內(nèi)容
                $substr = $tag.Substring(9)
                if ($substr -like "/packages/*")
                {
                    # 查找第一個雙引號的位置
                    $index = $substr.IndexOf('"')
                    # 獲取部分/packages/Newtonsoft.Json/13.0.3
                    $substr = $substr.Substring(0,$index)
                    # 排除報告濫用a標簽
                    if ($substr -notlike "*/ReportAbuse")
                    {
                        # 排除聯(lián)系作者a標簽
                        if ($substr -notlike "*/ContactOwners")
                        {
                            # 匹配版本
                            $endIndex = $substr.LastIndexOf('/')
                            $startPackageIndex = $endIndex + 1
                            $packageVersion = $substr.Substring($startPackageIndex)
                            # 下載地址nupkg
                            $packageUrl = "{0}{1}/{2}" -f $httpPrefix,$packageName,$packageVersion
                            # 生成保存文件的路徑
                            $packageFile = Join-Path -Path $outputDirectory -ChildPath "$packageName.$packageVersion.nupkg"
                            # 下載 .nupkg 文件
                            Write-Host "Downloading $packageName version $packageVersion from $packageUrl"
              Invoke-WebRequest -Uri $packageUrl -OutFile $packageFile
                            
                        }
                        
                    }
                    
                }
                
            }
            
        }
}
# 執(zhí)行結(jié)束暫停
$null = Read-Host
