如何将此 bash 转换为 powershell 变量

Question

我需要将以下 bash 变量转换为 powershell 变量

event='[ {"id": "'"$RANDOM"'", "eventType": "recordInserted", "subject": "myapp/vehicles/motorcycles", "eventTime": "'`date +%Y-%m-%dT%H:%M:%S%z`'", "data":{ "make": "Contoso", "model": "Monster"},"dataVersion": "1.0"} ]'

我发现如何更换

date +%Y-%m-%dT%H:%M:%S%z

经过

$eventtimesend = Get-Date -UFormat "%Y%m%d%H%M"

但不确定如何替换或需要修改哪些内容才能注入 2 个变量 $eventtimesend 和 $RANDOM 以与 powershell 语法兼容。

感谢您的帮助

使用可扩展的此处字符串，然后将变量表达式嵌套在字符串中：

$eventtimesend = Get-Date -UFormat "%Y%m%d%H%M"

$eventJson = @"
[ {"id": "'"$RANDOM"'", "eventType": "recordInserted", "subject": "myapp/vehicles/motorcycles", "eventTime": "${eventtimesend}", "data":{ "make": "Contoso", "model": "Monster"},"dataVersion": "1.0"} ]
"@

... 或者，直接在字符串文字中的子表达式 $(...) 中进行 Get-Date 调用：

$eventJson = @"
[ {"id": "'"$RANDOM"'", "eventType": "recordInserted", "subject": "myapp/vehicles/motorcycles", "eventTime": "$(Get-Date -UFormat "%Y%m%d%H%M")", "data":{ "make": "Contoso", "model": "Monster"},"dataVersion": "1.0"} ]
"@

$RANDOM 呢？

PowerShell 没有任何自动变量，如 $RANDOM，因此您需要将其替换为对 Get-Random 的调用：

$eventJson = @"
[ {"id": "$(Get-Random -Maximum ([int16]::MaxValue + 1))", "eventType": "recordInserted", "subject": "myapp/vehicles/motorcycles", "eventTime": "$(Get-Date -UFormat "%Y%m%d%H%M")", "data":{ "make": "Contoso", "model": "Monster"},"dataVersion": "1.0"} ]
