Question

我试图使用Powershell和Newtonsoft dll来验证Json对Schema的影响。如果我在Powershell.exe或Powershell ISE上运行它，我的脚本运行正常，但如果我使用VS Code（在同一台PC上）运行它，它就不起作用。

$Json_file = "D:\Json\file_sample.json"
$Json_file_wrong = "D:\Json\file_sample_wrong.json"
$Json_Schema_file = "D:\Json\schema_sample.json"

$Json = Get-Content $Json_file
$Json_wrong = Get-Content $Json_file_wrong
$SchemaJson = Get-Content $Json_Schema_file

$Json_dll = "D:\Json\Json110r1\Bin\net45\Newtonsoft.Json.dll"
$Json_Schema_dll = "D:\Json\JsonSchema30r9\Bin\net45\Newtonsoft.Json.Schema.dll"

Add-Type -Path $Json_dll
Add-Type -Path $Json_Schema_dll

$source = @'
    public class Validator
    {
        public static System.Collections.Generic.IList<string> Validate(Newtonsoft.Json.Linq.JToken token, Newtonsoft.Json.Schema.JSchema schema)
        {
            System.Collections.Generic.IList<string> messages;
            Newtonsoft.Json.Schema.SchemaExtensions.IsValid(token, schema, out messages);

            return messages;
        }
    }
'@
Add-Type -TypeDefinition $source -ReferencedAssemblies $Json_dll, $Json_Schema_dll

function Validate_Json_Against_Schema {
    param (
    [Parameter(Mandatory=$True)] $Json_param,
    [Parameter(Mandatory=$True)] $Schema_param
    )
$valid = $false

$Token = [Newtonsoft.Json.Linq.JToken]::Parse($Json_param)
$Schema = [Newtonsoft.Json.Schema.JSchema]::Parse($Schema_param)

$result = [Validator]::Validate($Token,$Schema)

if ($result.Count -eq 0)
    {
    $valid = $true
    }
return $valid
}

Validate_Json_Against_Schema $Json $SchemaJson
Validate_Json_Against_Schema $Json_wrong $SchemaJson

如果我使用VS Code（版本1.12.1，Powershell扩展版本1.6.0）运行它，我有这样的错误：

Cannot convert argument "token", with value: "{
  "shipping_address": {
    "street_address": "1600 Pennsylvania Avenue NW",

我试图在Windows 7 x86上运行它 - 结果相同。我做错了什么？

我记得有一个错误在VS Code和PowerShell扩展中听到了类，但无法回想起它是什么。您的脚本正在通过集成终端在VS Code中执行，该终端是后端的PowerShell编辑器服务。

您的代码在该集成终端中执行的主机与通过PowerShell.exe或ISE获得的主机不同。我建议将VS Code日志的问题提交到PS Extension repo：https://github.com/powershell/vscode-powershell/issues

Powershell Code在Powershell.exe和Powershell ISE上运行良好，但不能在VS Code上运行
