使用PowerShell和OData API将文件上载到SharePoint 2010

2023年12月9日 309次阅读

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

我收到的错误是：

Invoke-WebRequest :
An error occurred while
processing this request. At

**编辑**

该文件的原始内容：

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

est.

该脚本确实在服务器上创建了一个文件,但是具有以下内容：

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.

我错过了什么？我需要包含内容长度吗？设置MIME类型？

最佳答案 要创建附件资源,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,我在提供的示例中指出了指定的body参数($payload)无效.

以下示例演示如何通过SharePoint 2010 REST Interface上载附件文件：

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

在通过Fiddler执行一些分析之后,确定适当的端点URL应该是：

/_vti_bin/listdata.svc/Attachments HTTP/1.1

代替：

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

修改的例子

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 {}

}
