Question

我正在尝试使用下面的代码将文件从本地上传到SharePoint。但不知何故，这个错误信息被抛出，让我想知道原因：

Exception calling "UploadFile" with "3" argument(s): 
"An exception occurred during a WebClient request."
    + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId :              Microsoft.PowerShell.Commands.WriteErrorException,CopyFileToSharePoint.ps1

有人有什么想法吗？

运行脚本的用户具有上传文件的权限，例如以交互方式使用IE。
不，这是一个远程服务器，因此我无法使用Microsoft.SharePoint类。

代码

#Copy the file to the destination on SharePoint using WebClient
$SourceFile = $SourcePath + "\" + $FileName
$DestinationFile = $DestinationPath + "/" + $FileName

$client = new-object System.Net.WebClient
$client.UseDefaultCredentials=$true

if ( -not (Test-Path $DestinationPath) ) {
New-Item $DestinationPath -Type Directory  | Out-Null
}

$result |% {
Write-Host "Uploading $SourceFile to $DestinationFile"

try{
    $client.UploadFile($SourceFile, $DestinationFile)
}
catch{
    #one simple retry...
    try{
        $client.UploadFile($SourceFile, $DestinationFile)
    }
    catch{
        write-error "Failed to upload $SourceFile, $_"
    }
}
}

Answer 1

解决！最终似乎有用的是设置contenttype：

$client.ContentType = "application/octet-stream";

以某种方式解决了这个问题。有想法尝试从这个线程： Error using HttpWebRequest to upload files with PUT

Answer 2

Also, the file you uploading should be 'Checked Out' in the SharePoint Library before run the UploadFile command. If not, UploadFile throws the above MethodException error of 3 arguments. I recreated this error manually toggling the SharePoint Library settings 'Allow Documents to be checked out before editing?'. But I don't know if we can do the check out/in using System.Net.WebClient programatically. (Din't find anything in the Documentation though)

Powershell：使用System.Net.WebClient.UploadFile将文件上载到SharePoint时出现WriteErrorException
