使用REST API将文件上传到SharePoint 2013

Question

我已经写了这段代码

  $spSiteUrl = "http://mysharepoint/sites/site/web/"
  $cmd = "_api/web/lists/getbytitle('$docLib')/rootfolder/files/add(url='" + $file.Name + "', overwrite=true)"
  $digest = "got valid digest through code";
  $mediaType = new-object("System.Net.Http.Headers.MediaTypeWithQualityHeaderValue") "application/json"
  $handler = new-object("System.Net.Http.HttpClientHandler")
  $handler.UseDefaultCredentials= $true
  $client = New-Object("System.Net.Http.HttpClient") $handler        
  $client.BaseAddress = $spSiteUrl
  $client.DefaultRequestHeaders.Accept.Clear()    
  $client.DefaultRequestHeaders.Accept.Add($mediaType);
  $client.DefaultRequestHeaders.Add("Accept", "application/json;odata=verbose")
  $content = $null
  $client.DefaultRequestHeaders.Add("X-HTTP-Method", "PUT")
  $client.DefaultRequestHeaders.Add("X-RequestDigest", $digest)
  $fileStream = [System.IO.File]::OpenRead($file.FullName)
  $streamContent = new-object ("System.Net.Http.StreamContent") $fileStream
  $task = $client.PostAsync($cmd, $streamContent)
  $response = $task.Result
  $content = $response.Content.ReadAsStringAsync().Result
  Write-Host $content
  $fileStream.Close()
  $fileStream.Dispose()
  $response = $response.EnsureSuccessStatusCode()
  $client.Dispose()

在这里，我已经有一个有效的摘要值，该值是通过对_api / contextinfo进行POST获得的

但是当我执行此代码时，我得到一个错误

{“ error”：{“ code”：“-2147024891，System.UnauthorizedAccessException”，“ message”：{“ lang”：“ en-US”，“ value”：“访问被拒绝。您无权执行此操作操作或访问此资源。“}}} _api / web / lists / getbytitle（'test'）/ rootfolder / files / add（url ='BaselineFinishTag_2014_06.log'，overwrite = true）

在这里您可以看到我正在使用UseDefaultCredentials为true。 此代码使用作为场管理员和网站集管理员的帐户运行，并且对正在运行此代码的网站具有完全所有权。

您能告诉我我在这段代码中遗漏了什么，导致我得到UnAuthorizedException吗？

从PowerShell中使用SharePoint 2013 REST API的文章介绍了如何在PowerShell中使用REST API执行CRUD操作。

以下函数演示了如何使用指定文章中的Invoke-RestSPO.ps1函数通过SharePoint 2013 REST上传文件：

如何在PowerShell中使用REST API上传文件

[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client")
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.Runtime")
. ".\Invoke-RestSPO.ps1" #Load Invoke-RestSPO function

Function Upload-SPOFile(){

Param(
  [Parameter(Mandatory=$True)]
  [String]$WebUrl,

  [Parameter(Mandatory=$True)]
  [String]$UserName,

  [Parameter(Mandatory=$True)]
  [String]$Password, 

  [Parameter(Mandatory=$True)]
  [String]$FolderUrl,

  [Parameter(Mandatory=$True)]
  [System.IO.FileInfo]$FileInfo

)


   $Url = $WebUrl + "/_api/web/GetFolderByServerRelativeUrl('" + $FolderUrl + "')/Files/add(url='" + $FileInfo.Name + "',overwrite=true)"
   $FileContent = [System.IO.File]::ReadAllBytes($FileInfo.FullName)

   $contextInfo = Get-SPOContextInfo  $WebUrl $UserName $Password
   Invoke-RestSPO -Url $Url -Method Post -UserName $UserName -Password $Password -Body $FileContent  -RequestDigest $contextInfo.GetContextWebInformation.FormDigestValue
}



#Usage: upload file into SharePoint Online  
$UserName = "username@contoso.onmicrosoft.com"
$Password = Read-Host -Prompt "Enter the password"    
$WebUrl = "https://contoso.sharepoint.com/"
$FolderUrl = "/Shared Documents"
$UploadFileInfo = New-Object System.IO.FileInfo("C:\Users\user\Documents\SharePoint User Guide.docx")


Upload-SPOFile -WebUrl $WebUrl -UserName $UserName -Password $Password -FolderUrl $FolderUrl -FileInfo $UploadFileInfo
