Question

我希望能够使用Windows命令行下载Code Collaborator中与更改列表关联的修补程序。如果单击“外部差异”，则这些是您在Web GUI中获得的文件。它们有一个扩展名“.collabdiff”，实际上是包含每个文件“之前”和“之后”文件夹的压缩档案。我打算使用这些来使用Subversion Merge进行三向合并。

我的第一种方法是使用Code Collaborator命令行实用程序，例如

ccollab admin wget externaldiff?reviewid=%2^&changelistid=%3 > %OutputFile%

不幸的是，它似乎只需要ASCII数据，因为屏幕上会出现很多文字，并且会发出很多哔哔声。

我的下一个方法是直接使用外部链接。为此，我重新使用了我在网络上找到的一段PowerShell脚本：

::
:: GetCodeCollaboratorChangeList.cmd
::
:: Downloads a review change list from Code Collaborator.
::
:: %1   Code Collaborator Server
:: %2   Review Id
:: %3   Change List Id
::
@ECHO ON

    SETLOCAL

    SET OutputFile=%~dp0ChangeList_%2_%3.collabdiff

    ECHO Creating %OutputFile%.

    :: Sadly, the following line expects that ASCII text should be returned, but the URL returns binary text.
    :: It beeps a little, and not much text gets redirected.
    ::ccollab admin wget externaldiff?reviewid=%2^&changelistid=%3 > %OutputFile%

    :: So instead, we have to use our own download code.
    SET URL="%1/externaldiff?reviewid=%2&changelistid=%3"

    SET S=""
    SET S="%S:~1,-1% $webclient = New-Object System.Net.WebClient;"
    SET S="%S:~1,-1% $webclient.DownloadFile('%URL:~1,-1%','%OutputFile%');"

    PowerShell.exe -ExecutionPolicy unrestricted -noprofile -command "& {%S:~1,-1%}"

EXIT /B

可悲的是，我收到以下错误：

Exception calling "DownloadFile" with "2" argument(s): "The remote server returned an error: (500) Internal Server Error."
At line:1 char:74
+ & { $webclient = New-Object System.Net.WebClient; $webclient.DownloadFile <<<< ('http://server1/externaldiff?reviewid=8077&changelistid=52915','C:\Documents and Settings\Administrator\Desktop\ChangeList_8077_52915.collabdiff');}
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

在获取URL并将其粘贴到浏览器中（而不是单击链接）时，您将看到以下页面：

我尝试修改代码以分别修改QueryString和BaseAddress属性，并调用.DownloadFile('/externaldiff, ...)，但错误没有变化。

有关于如何下载这些文件的建议吗？

Answer 1

尝试：
ccollab admin wget'diff？context = 10＆amp; reviewid = REVIEWID'
例如：
ccollab admin wget'diff？context = 10＆amp; reviewid = 12345'

从Code Collaborator下载.collabdiff文件
