Question

我们需要一个批处理脚本来查看已经激活的映射，删除映射并重新映射一次但使用新密码。

我有以下代码示例：

@echo off
set server=srv1

for /f "tokens=1,2*" %%a in ('wmic logicaldisk get Caption^, providername^| find /I "%server%"')  do ( 
    for /f "tokens=1,2*" %%d in ("%%a") do ( 
        echo net use %%a /del 
        for /f "tokens=1,2*" %%e in ("%%a", "%%b") do (
            echo net use %%a %%b /user:dom/uid1 pwd
        )
    )
)

问题是我需要先删除所有映射，然后再进行所有重映射。

我目前的代码有：删除，重新映射，删除，重新映射。

有人能用我的代码示例帮助我吗？

Answer 1

要做你想做的事，你需要存储当前的映射somwhow。我会在类似数组的环境变量中执行此操作，例如$MAP[1]，$MAP[2]。由于Caption属性似乎始终是驱动器号加上冒号，并且ProviderName属性似乎总是UNC路径，因此变量$MAP[1]可能包含<Caption>|<ProviderName>之类的内容}。

因此，让我们建立两个独立的循环，第一个循环执行删除和数据存储，第二个循环执行重新映射活动 - 例如：

@echo off
set "SERVER=srv1"

rem // Initialise index counter:
set /A "COUNT=0"
rem /* Capture output of the `wmic` command line that is filtered by a `where` clause;
rem    this returns only the drives, filtered for network drives (`DriveType=4`);
rem    two nested loops avoid text conversion artefacts like orphaned CR marks: */
for /F "delims=" %%K in ('
    wmic LogicalDisk where "DriveType=4 and ProviderName like '\\\\%SERVER%\\%%'" get DeviceID /VALUE
') do for /F "tokens=1* delims==" %%I in ("%%K") do (
    rem /* Capture output of the `wmic` command line that returns the mapping target
    rem    that corresponds with the current drive: */
    for /F "delims=" %%G in ('
        wmic LogicalDisk where "DeviceID='%%J'" get ProviderName /VALUE
    ') do for /F "tokens=1* delims==" %%E in ("%%G") do (
        rem // Increment index counter:
        set /A "COUNT+=1"
        rem // Revert handling of `&` by `wmic`, hence replace `&amp;` by `&`:
        set "NAME=%%F" & call set "NAME=%%NAME:&amp;=&%%"
        rem /* Store current mapping into array-like variable;
        rem    `call` and double-`%` in `%%COUNT%%` are necessary as `COUNT` is modified
        rem    and read within the same block of code (`%COUNT%` would return `0`): */
        call set "$MAP[%%COUNT%%]=%%J|%%NAME%%"
        rem // Delete the current mapping:
        ECHO net use %%J /DELETE
    )
)

rem // Loop over all array elements:
for /F "tokens=1-2* delims=|=" %%H in ('2^> nul set $MAP[') do (
    rem // Establish remapping with new user data:
    ECHO net use %%I "%%J" pwd /USER:dom/uid1
    rem // Delete handled array element:
    set "%%H="
)

当然，您需要先设置和调整过滤器变量SERVER（用于替换where命令的find子句。我将搜索字符串更改为\\%SERVER%\，因此只匹配完整的服务器名称。

此方法正确处理包含 SPACE 和＆符号（&）的网络路径。

要实际删除并重新映射远程路径，请删除大写ECHO命令。

非常感谢aschipfl！ Scipt工作得非常好！如果连接到多个域，我还要添加一个关于cmdkey的部分来处理用户/ PWD。最后这里是我的compl scipt：

for /F "delims=" %%K in ('
    wmic LogicalDisk where "DriveType=4 and ProviderName like '\\\\%SERVER%\\%%'" get DeviceID /VALUE

        call set "$MAP[%%COUNT%%]=%%J|%%NAME%%"
        rem // Delete the current mapping:
        net use %%J /DELETE
        cmdkey /delete:%SERVER%

    net use %%I "%%J" /PERSISTENT:YES

当然，cmdkey运行了几次，但没关系。非常感谢您的帮助！ Beste regrads AxelF
