使用 PowerShell 和 OData 将文件上传到 SharePoint 2010 API

Question

我正在尝试将文件上传到 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

我收到一条错误消息：

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

** 编辑 **

文件原内容：

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.

该脚本确实在服务器上创建了一个文件，但内容如下：

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.

我错过了什么？我需要包括内容长度吗？设置 MIME 类型？

为了创建附件资源，必须指定以下属性：

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

话虽如此，我的结论是指定的 body 参数 ($payload) 在提供的示例中无效。

以下示例演示如何通过 SharePoint 2010 REST 接口上传附件文件：

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

通过 Fiddler 进行一些分析后，确定正确的端点 url 应该是：

/_vti_bin/listdata.svc/Attachments HTTP/1.1

而不是：

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

修改示例

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 {}

}
