在 powershell 中比较 JSON 文件

Question

################File-1.json####################

{
      "aaa-prod-release-branch": {
        "value": "release/S1.1-000000T01"
      },
      "bbb-prod-release-branch": {
        "value": "release/S2.2-000000T02"
      },
      "ccc-prod-release-branch": {
        "value": "release/S3.3-000000T03"
      }
    }

################File-2.json####################

{
  "aaa-current-release-branch": {
    "value": "release/S1.1-000000T01"
  },
  "bbb-current-release-branch": {
    "value": "release/S2.2-000000T02"
  },
  "ccc-current-release-branch": {
    "value": "release/S3.3-000000T044"
  },
  "ddd-current-release-branch": {
    "value": "releases/R4.4-000000T04"
  }
}

我有两个包含上述内容的 JSON 文件。我需要比较这两个文件并在powershell中获得差异。

1. 仅比较两个文件中存在的存储库的分支名称，并获取相应存储库的分支名称。

例如：只比较 aaa、bbb 和 ccc 分支，而不是 ddd，因为它在两个文件中都不存在。

对于 file-1.json 中的每个 repo (aaa, bbb, ccc) 值（存在于两个文件中），我需要比较 File-2.json 中的各个 repo 值。

示例： ccc-prod-release-branch（cc 是 repo 名称）值在 File-2.json 中不同。在这种情况下，在这种情况下获取分支值和 repo 名称 ccc。

发布/S3.3-000000T03

发布/S3.3-000000T044

然后使用上面的值来克隆 ccc repo 并比较这两个分支。我需要一种在 powershell 中执行此操作的方法。

对于 ddd-current-release-branch 分支，因为它是新分支，我只想运行一个克隆并获取该分支中的所有提交。

如何在 powershell 脚本中执行此操作。 ?

这是一个不错的起点。我正在对您的真实命名约定等做出一些假设：

# Get your json text as an object
$json1 = Get-Content '.\file1.json' | ConvertFrom-Json
$json2 = Get-Content '.\file2.json' | ConvertFrom-Json

# Your json example comes in as a single object with each repo as a property, which isn't what you want:

aaa-prod-release-branch         bbb-prod-release-branch         ccc-prod-release-branch        
-----------------------         -----------------------         -----------------------        
@{value=release/S1.1-000000T01} @{value=release/S2.2-000000T02} @{value=release/S3.3-000000T03}

所以将笨拙的 json 转换为 powershell 对象列表：

$prod = Foreach ($repo in $json1.psObject.Properties) {
  [pscustomobject][ordered]@{
    repoName    = $repo.Name -replace '-prod-release-branch'
    branchName  = $repo.Name
    releaseName = $repo.Value.Value
}}
$current = Foreach ($repo in $json2.psObject.Properties) {
  [pscustomobject][ordered]@{
    repoName    = $repo.Name -replace '-current-release-branch'
    branchName  = $repo.Name
    releaseName = $repo.Value.Value
}}

# Outputs:

repoName branchName              releaseName           
-------- ----------              -----------           
aaa      aaa-prod-release-branch release/S1.1-000000T01
bbb      bbb-prod-release-branch release/S2.2-000000T02
ccc      ccc-prod-release-branch release/S3.3-000000T03

然后根据需要比较它们会容易得多：

# Example: list all differences
Compare-Object $prod $current -Property 'ReleaseName' -IncludeEqual -PassThru

repoName branchName                 releaseName             SideIndicator
-------- ----------                 -----------             -------------
aaa      aaa-prod-release-branch    release/S1.1-000000T01  ==           
bbb      bbb-prod-release-branch    release/S2.2-000000T02  ==           
ccc      ccc-current-release-branch release/S3.3-000000T044 =>           
ccc      ccc-prod-release-branch    release/S3.3-000000T03  <=           
ddd      ddd-current-release-branch releases/R4.4-000000T04 =>           

# Example: repos that need full clone
$ToClone = $current | Where { $_.repoName -NotIn $prod.repoName }
