java - 使用powershell下载jdk

Question

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

.正如作者指定的那样，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

内容未加载，仅下载了大约 6KB。我有疑问，powershell脚本的下载限制是不是只有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)

Answer 1

在 oracle 站点上检查 session 时，以下 cookie 引起了注意: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)
