PowerShell, вызывающий Sharepoint 2013 REST API, список обновленных элементов

Question

После попытки нескольких разных примеров я не могу обновить элементы списка с помощью API-интерфейса Sharepoint. Я получаю обратно 400 запросов от запроса.

К слову, это связано с тем, что Sharepoint отправляет оба ID и Id по какой-либо причине и разбивает ConvertFrom-Json в моем методе Get-SPListItems.

function Update-SPListItems 
{ 
    param 
    (
     $listUpdate 
    ) 
    $requestDigest = Get-RequestDigest 

    foreach($item in $listUpdate.Results) 
    { 
     $restUrl = $item.__metadata.uri 
     $item.tsFeedbackStatus = "Open" 
     $item.Modified = Get-Date -Format s 

     $updatedItem = $item | ConvertTo-Json 
     #convert back the duplicate field 
     $updatedItem = $updatedItem -creplace '"ignoreId":','"Id":' 

     $itemJsonBytes = [System.Text.Encoding]::ASCII.GetBytes($updatedItem) 
     try 
     { 
      #examples have shown POST/MERGE, POST/PATCH, MERGE/MERGE, 
      #PATCH/PATCH, none of them in those combinations have worked 
      $request = [System.Net.WebRequest]::Create($restUrl) 
      $request.Credentials = $Credential.GetNetworkCredential() 
      $request.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f") 
      $request.Headers.Add("If-Match", "*") 
      $request.Headers.Add("X-RequestDigest", $requestDigest) 
      $request.Headers.Add("X-HTTP-Method", "MERGE") 
      $request.Accept = "application/json;odata=verbose" 
      $request.Method = "POST" 
      $request.ContentType = "application/json;odata=verbose" 
      $request.ContentLength = $itemJsonBytes.Length 
      $stream = $request.GetRequestStream() 
      $stream.Write($itemJsonBytes, 0, $itemJsonBytes.Length) 
      $stream.Close() 

      $response = $request.GetResponse() 
     } 
     catch [System.Exception] 
     { 
      Write-Error $_.Exception.ToString()   
     } 

    } 
} 

Вот точная ошибка:

Update-SPListItems : System.Net.WebException: The remote server returned an error: (400) Bad Request.

Попробуйте ниже многоразовые функции для этого. Он работал для меня каждый раз. Убедитесь, что параметры переданы правильно. У этого есть встроенная в него аутентификация и даже работает для более старых версий PowerShell.

function Request-Rest{  
    [CmdletBinding()] 
    PARAM (
     [Parameter(Mandatory=$False)] 
     [String]$Metadata, 

     [Parameter(Mandatory=$true)] 
     [String] $URL, 

     [Parameter(Mandatory=$False)] 
     [Switch]$listUpdate, 

     [Parameter(Mandatory=$False)] 
     [String]$RequestDigest, 

     [Parameter(Mandatory=$false)] 
     [Microsoft.SharePoint.Client.SharePointOnlineCredentials] $credentials, 

     [Parameter(Mandatory=$false)] 
     [String] $UserAgent = "PowerShell API Client", 

     [Parameter(Mandatory=$false)] 
     [Switch] $JSON, 

     [Parameter(Mandatory=$false)] 
     [Switch] $Raw 
    ) 
    #Create a URI instance since the HttpWebRequest.Create Method will escape the URL by default. 
    #$URL = Fix-Url $Url 
    $URI = New-Object System.Uri($URL,$true) 

    #Create a request object using the URI 
    $request = [System.Net.HttpWebRequest]::Create($URI) 

    #Build up a User Agent 
    $request.UserAgent = $( 
     "{0} (PowerShell {1}; .NET CLR {2}; {3})" -f $UserAgent, $(if($Host.Version){$Host.Version}else{"1.0"}), 
     [Environment]::Version, 
     [Environment]::OSVersion.ToString().Replace("Microsoft Windows ", "Win") 
     ) 

    if ($credentials -eq $null) 
    { 
     $request.UseDefaultCredentials = $true 
    } 
    else 
    { 
     $request.Credentials = $credentials 
    } 

    $request.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f") 

    #Request Method 
    $request.Method = "POST" 

    #Headers 
    if($listUpdate) 
    { 
     $request.Headers.Add("X-RequestDigest", $RequestDigest) 
     $request.Headers.Add("If-Match", "*") 
     $request.Headers.Add("X-HTTP-Method", "MERGE") 

     $request.ContentType = "application/json;odata=verbose" 
     $request.Accept = "application/json;odata=verbose" 
    } 

    #Request Body 
    if($Metadata) { 
     $Body = [byte[]][char[]]$Metadata 
     $request.ContentLength = $Body.Length 

     $stream = $request.GetRequestStream() 
     $stream.Write($Body, 0, $Body.Length) 
    } 
    else { 
     $request.ContentLength = 0 
    } 


    try 
    { 
     [System.Net.HttpWebResponse] $response = [System.Net.HttpWebResponse] $request.GetResponse() 
    } 
    catch 
    { 
      Throw "Exception occurred in $($MyInvocation.MyCommand): `n$($_.Exception.Message)" 
    } 

    $reader = [IO.StreamReader] $response.GetResponseStream() 

    if (($PSBoundParameters.ContainsKey('JSON')) -or ($PSBoundParameters.ContainsKey('Raw'))) 
    { 
     $output = $reader.ReadToEnd() 
    } 
    else 
    { 
     $output = $reader.ReadToEnd() 
    } 

    $reader.Close() 

    if($output.StartsWith("<?xml")) 
    { 
     [xml]$outputXML = [xml]$output 
    } 
    else 
    { 
     [xml]$outputXML = [xml] ("<xml>" + $output + "</xml>") 
    } 

    Write-Output $outputXML 

    $response.Close() 
}
