我创建了一个powershell脚本，它创建了一个JSON文件，列出了目录中的所有文件及其大小和哈希码（我知道有更有效的方法可以做到这一点，但需要它）。出于某种原因，在保存文件信息的对象中，第一行返回错误： 错误：第8行的解析错误：
... { "fileName": ".\app.config", "
---------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'
似乎很清楚该属性是string类型，但由于某种原因，解析器无法解析它。 在未确定类型的情况下可能导致错误的原因是什么？ 下面的JSON文件供参考：
JSON文件似乎在大多数情况下正确生成，但出于某种原因，name和version属性被添加到文件的末尾而不是开头。这是powershell函数供参考：
function GenerateManifest([string] $manifestPath, [string] $packageName, [string] $version, [string] $hashCode, [string] $fwVersion, [string] $outputPath)
{
"{" > $manifestPath
$obj = @{
name = $packageName
version = $version
frameworkVersion = $fwVersion
files = @()
}
if($outputPath)
{
cd $outputPath
$files = Get-ChildItem -recurse | Where {($_.FullName -notlike $manifestPath) -And (-not ($_ -is [System.IO.DirectoryInfo]))}
if($files)
{
"""files"": [ " >> $manifestPath
foreach($file in $files)
{
if($file.name -eq $manifestPath)
{
continue;
}
$fileHash = GetFileHash($file.FullName)
$filePath = $file | resolve-path -relative
$fileObj = @{
fileName = $filePath
fileSize = $file.Length
hashCode = $fileHash
}
$obj.files += $fileObj
}
}
else
{
"no files found" >> $manifestPath
}
}
$json = $Obj | ConvertTo-Json
$json >> $manifestPath
}

你的JSON有几个问题。
基于JSONLint的错误，第一个问题不是很明显，但是因为fileName键的值包含未转义的反斜杠\所以它将其解释为无法识别的转义序列。这些需要更改为\\。
一旦你解决了这个问题，你就会发现没有逗号,分隔fileSize和hashCode密钥，并且哈希代码本身也需要引用，因为它们是是字符串。
如果您使用字符串连接生成此JSON，则应该停止并在PowerShell中创建一个对象，然后将其发送到ConvertTo-Json。这样的事可能（未经测试）：
$obj = @{
name = "Project name"
version = "2.0.8"
frameworkVersion = "4.0.73"
files = @()
}
Get-ChildItem -Path C:\my\Path -Recurse | ForEach-Object {
$fileObj = @{
fileName = $_.Name
fileSize = $_.Size
hashCode = Get-MyHashCode $_
}
$obj.files += $fileObj
}
$json = $myObj | ConvertTo-Json
