Question

所以，从这里继续我的可爱旅程通过powershell： Loop for two variables

我有一个ps1，它为一堆事务和一堆节点运行循环，并将它们发送到csv文件。

$url = "https://someserver/trans="
$transactions = '1','2','3','4' #There are 4 transactions
$nodes = 'node1','node2','node3','node4','node5','node6' #There are 10 nodes

Remove-Item ATM.csv -Force

# So far so good
# Below is what I'd use as a function in bash. No sure what/how to do in PS:
#OUTPUT:
foreach($transaction in $transactions)
{
    foreach($node in $nodes)
    {

    "$transaction;$node" |out-file -Append ATM.csv
    curl -k -u user@pass $url$transaction$node | findstr "<value>" | out-file -Append ATM.csv
  }
}

在excel中打开文件，我最终得到A列下的输出：

   transaction1;node1 (in the first row, left-most cell)
   value1 (from the curl. It's actually a number and it sits in the row right under the first entry)

等等2,3等等，其余的。只填充最左侧的列（A列）。

我想要的是将值放在三列中的方法，这样csv将如下所示：

Column A    | Column B | Column C
transaction1| node1    | valueX
transaction2| node2    | valueY

等等。该脚本或其他脚本必须执行此操作，运行脚本的此作业的最终用户不会每天打开Excel并开始运行宏，他需要从脚本中准备好最终的csv。

我该怎么做？

Answer 1

这样的事情会解决你的问题，唯一没有包含的就是从Invoke-WebRequest（curl）中选择值本身，因为这会根据返回的内容而改变。

foreach($transaction in $transactions)
{
    foreach($node in $nodes)
    {
    $value = Invoke-WebRequest -Uri $url$transaction$node -UseBasicParsing | Select-Object -Expand Content

    Add-Content -Path ATM.csv -Value "$transaction,$node,$value"
    }
}

您目前正在用两个不同的行编写输出。一种解决方案可能是在Out-File中使用NoNewLine参数：

我个人会创建一个Powershell对象并在最后创建csv：

"$transaction;$node" |out-file -Append ATM.csv -nonewline
curl -k -u user@pass $url$transaction$node | findstr "<value>" | out-file -Append ATM.csv

}

powershell脚本，csv文件中单元格中的文本放置
