问题描述

我尝试在sharepoint上下载文件的历史版本但总是得到"远程服务器返回错误：（403 ）禁止。"运行到"client.OpenRead（curFileVerUrl）;"时出错如下。有人可以提供建议吗？谢谢。

I tried to download history versions of a file on sharepoint but always get "The remote server returned an error: (403) Forbidden." error when run to "client.OpenRead(curFileVerUrl);" as following. Can anybody advise on it? Thank you.

使用（var context = new ClientContext（" https://test.sharepoint.com/CorpSrv/TestSite/"））

            {

                context.Credentials = new Microsoft.SharePoint.Client.SharePointOnlineCredentials（strUser，password）;



                string fileUrl =" https://test.sharepoint.com/CorpSrv/TestSite/TestDocLib/123.xlsx" ;;

                Uri fileuri = new Uri（fileUrl）;

                Microsoft.SharePoint.Client.File file = context.Web.GetFileByServerRelativeUrl（fileuri.AbsolutePath）;

                context.Load（file）;

                context.ExecuteQuery（）;
$


                FileVersionCollection版本= file.Versions;

                context.Load（版本）;

                context.ExecuteQuery（）;
$


                foreach（file.Versions中的Microsoft.SharePoint.Client.FileVersion _version）

                {

$
                    Uri filename = new Uri（con​​text.Url + _version.Url）;

                   使用（var client = new WebClient（））

                    {

                        client.Credentials = new NetworkCredential（strUser，password）;

                        string curFileVerUrl = context.Url + _version.Url;



                        System.IO.Stream data = client.OpenRead（curFileVerUrl）;

                    }¥b $ b                }¥b $ b            }

using (var context = new ClientContext("https://test.sharepoint.com/CorpSrv/TestSite/"))
            {
                context.Credentials = new Microsoft.SharePoint.Client.SharePointOnlineCredentials(strUser, password);

                string fileUrl = "https://test.sharepoint.com/CorpSrv/TestSite/TestDocLib/123.xlsx";
                Uri fileuri = new Uri(fileUrl);
                Microsoft.SharePoint.Client.File file = context.Web.GetFileByServerRelativeUrl(fileuri.AbsolutePath);
                context.Load(file);
                context.ExecuteQuery();

                FileVersionCollection versions = file.Versions;
                context.Load(versions);
                context.ExecuteQuery();

                foreach (Microsoft.SharePoint.Client.FileVersion _version in file.Versions)
                {

                    Uri filename = new Uri(context.Url + _version.Url);
                    using (var client = new WebClient())
                    {
                        client.Credentials = new NetworkCredential(strUser, password);
                        string curFileVerUrl = context.Url + _version.Url;

                        System.IO.Stream data = client.OpenRead(curFileVerUrl);
                    }
                }
            }

尝试检查您的密码是否已设置正确，下面的代码适用于我：

using (var context = new ClientContext("https://xxx.sharepoint.com/sites/dev"))
            {
                Console.ForegroundColor = ConsoleColor.Green;                                
                string password = "pw";
                SecureString sec_pass = new SecureString();
                Array.ForEach(password.ToArray(), sec_pass.AppendChar);
                sec_pass.MakeReadOnly();
                context.Credentials = new SharePointOnlineCredentials("[e-mail]", sec_pass);

                string fileUrl = "https://o365e3w15.sharepoint.com/sites/dev/Shared%20Documents/Document.docx";
                Uri fileuri = new Uri(fileUrl);
                Microsoft.SharePoint.Client.File file = context.Web.GetFileByServerRelativeUrl(fileuri.AbsolutePath);
                context.Load(file);
                context.ExecuteQuery();

                FileVersionCollection versions = file.Versions;
                context.Load(versions);
                context.ExecuteQuery();

                foreach (Microsoft.SharePoint.Client.FileVersion _version in file.Versions)
                {
                    Console.WriteLine(_version.VersionLabel + _version.Url);
                 
                }
                Console.ReadKey();
            }
