Question

我正在使用RESTAPI从设备中收集原始文本中的数据，我想替换其中的特定文本块。

我对类型不太满意，而且从几个小时开始就一直坚持下去。

让我们说这是我的原文：

{
"type":  "V9",
"firmware":  {
                 "manageFirmware":  false,
                 "reapplyState":  "NotApplying"
             },
"inProgress":  false,
"connectionSettings":  {
                           "reapplyState":  "NotApplying",
                           "connections":  [
                                               "@{id=1; name=PR_1; state=Deployed; status=OK}",
                                               "@{id=2; name=PR_2; state=Deployed; status=OK}",
                                               "@{id=3; name=SN_1; state=Reserved; status=Unknown;}",
                                               "@{id=4; name=SN_2; state=Reserved; status=Unknown;}"   
                                           ]
                       },
"Tag":  "123456"}

我想替换"connections" :之后的块：

[ "@{id=1; name=PR_1; state=Deployed; status=OK}",
  "@{id=2; name=PR_2; state=Deployed; status=OK}",
  "@{id=3; name=SN_1; state=Reserved; status=Unknown;}",
  "@{id=4; name=SN_2; state=Reserved; status=Unknown;}"
]

在我当前可以收集的另一个文本块中，让我们说这个：

[
{
    "id":  1,
    "name":  "PR_1",
    "state":  "Deployed",
    "status":  "OK",
},
{
    "id":  2,
    "name":  "PR_2",
    "state":  "Deployed",
    "status":  "OK",
},
{
    "id":  3,
    "name":  "SN_1",
    "state":  "Reserved",
    "status":  "Unknown",
},
{
    "id":  4,
    "name":  "SN_2",
    "state":  "Reserved",
    "status":  "Unknown",
}
]

我的目标是删除"@，将=替换为:，并在行尾删除}。

我已经使用-Replace选项尝试了一些操作，但这并不是很确定。

也尝试过使用一些正则表达式，但是我为此感到非常挣扎。

看起来提供的json已从psobject转换为深度为2的json。此代码会将其放回对象中，并将hashtables解析为connections属性的对象，然后将其深度转换回json之三，应该会得到您想要的

$json = @'
{
"type":  "V9",
"firmware":  {
                 "manageFirmware":  false,
                 "reapplyState":  "NotApplying"
             },
"inProgress":  false,
"connectionSettings":  {
                           "reapplyState":  "NotApplying",
                           "connections":  [
                                               "@{id=1; name=PR_1; state=Deployed; status=OK}",
                                               "@{id=2; name=PR_2; state=Deployed; status=OK}",
                                               "@{id=3; name=SN_1; state=Reserved; status=Unknown;}",
                                               "@{id=4; name=SN_2; state=Reserved; status=Unknown;}"   
                                           ]
                       },
"Tag":  "123456"}
'@

$obj = $json | ConvertFrom-Json

$obj.connectionSettings.connections = $obj.connectionSettings.connections | % {
    [pscustomobject](iex ($_ -replace '(?<=[=])([^;}]*)(?=[;}])', "'`$1'"))
}

$newjson = $obj | ConvertTo-Json -Depth 3

$newjson

用另一段替换文本
