【中文标题】使用powershell下载jdk【英文标题】：Downloading jdk using powershell 【发布时间】：2014-08-17 06:48:47 【问题描述】：

我正在尝试使用下面链接中给出的 powershell 脚本下载 java jdk

http://poshcode.org/4224

。正如作者所指定的，如果我更改存在最新 jdk 的源 url 即，

http://download.oracle.com/otn-pub/java/jdk/8u5-b13/jdk-8u5-windows-x64.exe

内容没有被加载，只有大约 6KB 被下载。我有一个疑问，powershell脚本的下载限制是否只有6KB？

代码如下：

$source = "http://download.oracle.com/otn-pub/java/jdk/8u5-b13/jdk-8u5-windows-i586.exe"
      $destination = "C:\Download\Java\jdk-7u60-windows-i586.exe"
      $client = new-object System.Net.WebClient
      $client.DownloadFile($source, $destination)

【问题讨论】：

作者可能不是从oracle网站下载的... 【参考方案1】：

在检查 oracle 站点上的会话时，以下 cookie 引起注意：oraclelicense=accept-securebackup-cookie。考虑到这一点，您可以运行以下代码：

$source = "http://download.oracle.com/otn-pub/java/jdk/8u5-b13/jdk-8u5-windows-i586.exe"
$destination = "C:\Download\Java\jdk-7u60-windows-i586.exe"
$client = new-object System.Net.WebClient 
$cookie = "oraclelicense=accept-securebackup-cookie"
$client.Headers.Add([System.Net.HttpRequestHeader]::Cookie, $cookie) 
$client.downloadFile($source, $destination)

编辑：这是您的问题的原因：您不能在没有接受条款之前直接下载文件。

我正在使用以下脚本下载文件。它与 HTTP 以及 FTP 一起使用。这对您的任务来说可能有点矫枉过正，因为它还会显示下载进度，但您可以对其进行修剪，直到它适合您的需要为止。

    $eventDataComplete = Register-ObjectEvent $client DownloadFileCompleted `
        -SourceIdentifier WebClient.DownloadFileComplete `
        -Action $Global:downloadComplete = $true
    $eventDataProgress = Register-ObjectEvent $client DownloadProgressChanged `

        -Action  $Global:DPCEventArgs = $EventArgs     


process 
    Write-Progress -Activity 'Downloading file' -Status $url
    $client.DownloadFileAsync($url, $localFile)

感谢代码，但不幸的是它没有下载完整的 exe，只下载了 6KB。我使用的网址是：download.oracle.com/otn-pub/java/jdk/8u5-b13/… 这就是我打开 URL 时遇到的问题：对不起！要从 Oracle 技术网下载产品，您必须同意 OTN 许可条款。请确保... 您的浏览器启用了“cookies”和 javascript。您为要下载的产品单击了“接受许可”。您在接受许可后 30 分钟内尝试下载。从这里你可以去... 返回上一页 站点地图 OTN 主页 所以这就是你的问题的原因：你不能在不接受之前的条款的情况下直接下载文件。 但现在我确定问题出在条款协议上。如果您保存错误网站，它的大小与您正在下载的文件的大小完全相同。您甚至可以将下载的文件从 .exe 重命名为 .html 并在浏览器中打开。 有一个想法，但它很脏。您可以使用 JMeter 之类的工具来记录 HTTP 调用的宏，从而引导您接受下载条款，并尝试通过直接发送 HTTP 请求来重现路径。不知道它是否有效。【参考方案3】：

在需要 JDK 作为依赖项的平台安装程序需要此脚本后：

<# Config #>
$DownloadPageUri = 'https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html';
$JavaVersion = '8u201';

<# Build the WebSession containing the proper cookie 
   needed to auto-accept the license agreement. #>
$Cookie=New-Object -TypeName System.Net.Cookie; 
$Cookie.Domain='oracle.com';
$Cookie.Name='oraclelicense';
$Cookie.Value='accept-securebackup-cookie'; 
$Session= `
   New-Object -TypeName Microsoft.PowerShell.Commands.WebRequestSession;
$Session.Cookies.Add($Cookie);

<# Fetch the proper Uri and filename from the webpage. #>
$JdkUri = (Invoke-WebRequest -Uri $DownloadPageUri -WebSession $Session -UseBasicParsing).RawContent `
    -split "`n" | ForEach-Object  `
        If ($_ -imatch '"filepath":"(https://[^"]+)"'  `
            $Matches[1] `
         `
     | Where-Object  `
        $_ -like "*-$JavaVersion-windows-x64.exe" `
    [0];
If ($JdkUri -imatch '/([^/]+)$')  
    $JdkFileName=$Matches[1];


<# Use a try/catch to catch the 302 moved temporarily 
   exception generated by oracle from the absance of
   AuthParam in the original URL, piping the exception's
   AbsoluteUri to a new request with AuthParam returned
   from Oracle's servers.  (NEW!) #>

try  
    Invoke-WebRequest -Uri $JdkUri -WebSession $Session -OutFile "$JdkFileName"
 catch  
    $authparam_uri = $_.Exception.Response.Headers.Location.AbsoluteUri;
    Invoke-WebRequest -Uri $authparam_uri -WebSession $Session -OutFile "$JdkFileName"

在 PowerShell 6.0 中工作（Hello 2019！）需要对正则表达式和 -imatch 行扫描的方式进行小幅修复。遵循 302 重定向的解决方法位于此处：https://github.com/PowerShell/PowerShell/issues/2896（fcabralpacheco 重新调整了 302 重定向解决方法以使 Oracle 下载再次正常工作！

此解决方案自动下载适用于 Windows x64 的 8u201。

由于接受的评论不再有效，我无法发表评论，我将把我的方法留在这里。我修改了@steve-coleman 的答案，使其扫描页面以查找以https 而不是http 开头的下载链接。我还需要修改$Response 以拥有-UseBasicParsing 标志，因为我使用的是无头Windows Server。总而言之，我使用的脚本是：

$DownloadPageUri = 'http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html'
$JavaVersion = '8u192'

$Response = Invoke-WebRequest -Uri $DownloadPageUri -UseBasicParsing

$JreUri = @($Response.RawContent -split "`n" | ForEach-Object If ($_ -imatch '"filepath":"(https://[^"]+)"') $Matches[1] | Where-Object $_ -like "*-$JavaVersion-windows-x64.tar.gz")
If (-Not $JreUri.Count -eq 1) 
    throw ('Expected to retrieve only one URI but got 0' -f $JreUri.Count)


If ($JreUri[0] -imatch '/([^/]+)$') 
    $JreFileName = $Matches[1]

$JreFileName = 'jre-windows-x64.tar.gz'

If (-Not (Test-Path -Path "$PSScriptRoot\$JreFileName") -Or -Not (Test-Path -Path "$PSScriptRoot\Java-$JavaVersion.tag")) 
    $Cookie  = New-Object -TypeName System.Net.Cookie
    $Cookie.Domain = 'oracle.com'
    $Cookie.Name   = 'oraclelicense'
    $Cookie.Value  = 'accept-securebackup-cookie'
    $Session = New-Object -TypeName Microsoft.PowerShell.Commands.WebRequestSession
    $Session.Cookies.Add($Cookie)
    Invoke-WebRequest -Uri $JreUri[0] -WebSession $Session -OutFile "$PSScriptRoot\$JreFileName"
    New-Item -Path "$PSScriptRoot\Java-$JavaVersion.tag" -ItemType File | Out-Null

像往常一样，YMMV，特别是如果 Oracle 更改他们的网站。

我将 Robert Smith 的答案修改如下以获得 SDK 8u211

<# Config #>
$DownloadPageUri = 'https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html';
$JavaVersion = '8u211';
<# Build the WebSession containing the proper cookie
   needed to auto-accept the license agreement. #>

$Cookie=New-Object -TypeName System.Net.Cookie;
$Cookie.Domain='oracle.com';
$Cookie.Name='oraclelicense';
$Cookie.Value='accept-securebackup-cookie';
$Session= `
   New-Object -TypeName Microsoft.PowerShell.Commands.WebRequestSession;
$Session.Cookies.Add($Cookie);

# Fetch the proper Uri and filename from the webpage. #>
$i = 0
#echo $i
#$rc = (Invoke-WebRequest -Uri $DownloadPageUri -WebSession $Session     -UseBasicParsing).RawContent
#echo $rc >> Oracle.html
#-split "`n" | ForEach-Object  `
$JdkUri = (Invoke-WebRequest -Uri $DownloadPageUri -WebSession $Session -UseBasicParsing).RawContent `
-split '\r?\n' | ForEach-Object  `
    #echo "$i : $_" >> Oracle.html
    #echo "$i"
    #$i++
    If ($_ -imatch '"filepath":"(https://[^"]+)"')  `
        $Matches[1] `
     `
 | Where-Object  `
    $_ -like "*-$JavaVersion-windows-x64.exe" `
[0];
If ($JdkUri -imatch '/([^/]+)$') 
    $JdkFileName=$Matches[1];

echo "JdkUri: $JdkUri" >> out.txt

<# Use a try/catch to catch the 302 moved temporarily
   exception generated by oracle from the absance of
   AuthParam in the original URL, piping the exception's
   AbsoluteUri to a new request with AuthParam returned
   from Oracle's servers.  (NEW!) #>

try 
    echo "In the try" >> out.txt
    Invoke-WebRequest -Uri $JdkUri -WebSession $Session -OutFile "$JdkFileName"
 catch 
    echo "In the catch" >> out.txt
    $authparam_uri = $_.Exception.Response.Headers.Location.AbsoluteUri;
    Invoke-WebRequest -Uri $authparam_uri -WebSession $Session -OutFile "$JdkFileName"

不得不换行 -拆分“n" | ForEach-Object 到 -split '\r?\n' | ForEach-Object `

还有那行 if ($_ -imatch '"filepath":"(https://[^"]+)"' to If ($_ -imatch '"filepath":"(https://[^"]+)"')

我不确定是谁投了反对票。但它工作正常。检查 DownloadPageUri、javaversion 和 JavaVersion-windows-x64.tar.gz 是否仍然有效。如果 oracle 更改任何内容，这将停止工作。 尝试设置 $JavaVersion = '8u191'，每次更新版本信息时都会中断。
