上傳文件到SharePoint 2010中使用PowerShell和OData的API

Question

我試圖將文件上載到SharePoint 2010：

Function Add-Attachments() 
{ 

    [CmdletBinding()] 
    Param(
     [Parameter(Mandatory=$True)] 
     [int]$Id, 
     [Parameter(Mandatory=$True)] 
     [string[]]$Paths 
    ) 

    BEGIN {} 
    PROCESS { 

     $url = "http://server/resource/_vti_bin/listdata.svc/TheList($Id)/Attachments" 

     Foreach ($Path in $Paths) { 

      Write-Verbose "Attaching $Path ..." 
      $headers = @{ 
       'Slug' = "TheList|$Id|$(Split-Path $path -Leaf)" 
      } 

      $Payload = @{filename=(Split-Path $path -Leaf);filecontent=([IO.File]::ReadAllBytes($path))} 

      Invoke-WebRequest -Uri $url -Method Post -UseDefaultCredentials -Body $Payload -Headers $headers 

     } # Foreach 

    } # PROCESS 
    END {} 

} 

Add-Attachments -Id 1234 -Paths 'C:\Users\gandalf\Desktop\test.txt' -verbose 

我收到一條錯誤：

Invoke-WebRequest : An error occurred while processing this request. At C:\Users\gandalf\Documents\WindowsPowerShell\Scripts\SP\SharePoint2010.ps1:382 char:13 + Invoke-WebRequest -Uri $url -Method Post -UseDefaultCredentials -Bod ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-WebRequest], WebException + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeWebRequestCommand

**編輯**

文件的原始內容：

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec a diam lectus. Sed sit amet ipsum mauris. Maecenas congue ligula ac quam viverra nec consectetur ante hendrerit. Donec et mollis dolor. Praesent et diam eget libero egestas mattis sit amet vitae augue. Nam tincidunt congue enim, ut porta lorem lacinia consectetur. Donec ut libero sed arcu vehicula ultricies a non tortor. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean ut gravida lorem. Ut turpis felis, pulvinar a semper sed, adipiscing id dolor. Pellentesque auctor nisi id magna consequat sagittis. Curabitur dapibus enim sit amet elit pharetra tincidunt feugiat nisl imperdiet. Ut convallis libero in urna ultrices accumsan. Donec sed odio eros. Donec viverra mi quis quam pulvinar at malesuada arcu rhoncus. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. In rutrum accumsan ultricies. Mauris vitae nisi at sem facilisis semper ac in est.

該腳本在服務器上創建一個文件，但與此內容：

filename=test.txt&filecontent=Lorem+ipsum+dolor+sit+amet%2c+consectetur+adipiscing+elit.+Donec+a+diam+lectus.+Sed+sit+amet+ipsum+mauris.+Maecenas+congue+ligula+ac+quam+viverra+nec+consectetur+ante+hendrerit.+Donec+et+mollis+dolor.+Praesent+et+diam+eget+libero+egestas+mattis+sit+amet+vitae+augue.+Nam+tincidunt+congue+enim%2c+ut+porta+lorem+lacinia+consectetur.+Donec+ut+libero+sed+arcu+vehicula+ultricies+a+non+tortor.+Lorem+ipsum+dolor+sit+amet%2c+consectetur+adipiscing+elit.+Aenean+ut+gravida+lorem.+Ut+turpis+felis%2c+pulvinar+a+semper+sed%2c+adipiscing+id+dolor.+Pellentesque+auctor+nisi+id+magna+consequat+sagittis.+Curabitur+dapibus+enim+sit+amet+elit+pharetra+tincidunt+feugiat+nisl+imperdiet.+Ut+convallis+libero+in+urna+ultrices+accumsan.+Donec+sed+odio+eros.+Donec+viverra+mi+quis+quam+pulvinar+at+malesuada+arcu+rhoncus.+Cum+sociis+natoque+penatibus+et+magnis+dis+parturient+montes%2c+nascetur+ridiculus+mus.+In+rutrum+accumsan+ultricies.+Mauris+vitae+nisi+at+sem+facilisis+semper+ac+in+est.

我缺少什麼？我是否需要包含內容長度？設置MIME類型？

Answer 1

爲了創建一個附件資源以下屬性必須被指定：

Endpoint Uri: http://server/site/_vti_bin/listdata.svc/entityset(itemid)/Attachments 
Method: POST 
Headers: 
    Slug: "entityset|itemid|name" 
    ContentType: */* 
Body: content 

話雖如此，我的conslution指定的body參數（$payload）是在所提供的示例無效。

下面的例子演示瞭如何上傳通過SharePoint 2010 REST接口附件文件：

Function Add-Attachments() 
{ 

    [CmdletBinding()] 
    Param(
     [Parameter(Mandatory=$True)] 
     [string]$WebUrl, 
     [Parameter(Mandatory=$True)] 
     [string]$ListName, 
     [Parameter(Mandatory=$True)] 
     [int]$ItemId, 
     [Parameter(Mandatory=$True)] 
     [string]$SourcePath 
    ) 

    BEGIN {} 
    PROCESS { 
     $endpointUri = New-Object System.Uri("$WebUrl/_vti_bin/listdata.svc/$ListName($ItemId)/Attachments") 
     $fileName = (Split-Path $SourcePath -Leaf) 
     $fileContent = ([IO.File]::ReadAllBytes($SourcePath)) 
     $headers = @{ 
       'Slug' = "$ListName|$ItemId|$fileName"; 
     } 

     Invoke-WebRequest -Uri $endpointUri -Method Post -UseDefaultCredentials -Body $fileContent -Headers $headers -ContentType "*/*" 

    } # PROCESS 
    END {} 

} 

用法：

Add-Attachments -WebUrl "http://contoso.intranet.com/" -ListName "Tasks" -ItemId 1 -SourcePath "C:\Users\user\Documents\SharePointUserGuide.docx" -verbose 

更新

通過提琴手，它進行一些分析後確定正確的端點url應該是：

/_vti_bin/listdata.svc/Attachments HTTP/1.1 

代替：

/_vti_bin/listdata.svc/Tasks(<id>)/Attachments HTTP/1.1 

修改例

Function Add-Attachments() 
{ 

    [CmdletBinding()] 
    Param(
     [Parameter(Mandatory=$True)] 
     [string]$WebUrl, 
     [Parameter(Mandatory=$True)] 
     [string]$ListName, 
     [Parameter(Mandatory=$True)] 
     [int]$ItemId, 
     [Parameter(Mandatory=$True)] 
     [string]$SourcePath 
    ) 

    BEGIN {} 
    PROCESS { 
     $endpointUri = New-Object System.Uri("$WebUrl/_vti_bin/listdata.svc/Attachments") 
     $fileName = (Split-Path $SourcePath -Leaf) 
     $fileContent = ([IO.File]::ReadAllBytes($SourcePath)) 
     $headers = @{ 
       'Slug' = "$ListName|$ItemId|$fileName"; 
     } 

     Invoke-WebRequest -Uri $endpointUri -Method Post -UseDefaultCredentials -Body $fileContent -Headers $headers -ContentType "*/*" 

    } # PROCESS 
    END {} 

}
