Office 365 Sharepoint Upload Files to Documents Li

问题:

I am trying to use the following code to add files to my document library on Sharepoint Office365 using web services.

public void SaveFileToSharePoint(string fileName)
        {
            try
            {
                var copyService = new Copy { Url = "https://mydomain.com/_vti_bin/copy.asmx", Credentials = new NetworkCredential("username", "password", "domain") };

                var destURL = "https://mydomain.com/Shared%20Documents/" + Path.GetFileName(fileName);

                string[] destinationUrl = { destURL };

                CopyResult[] cResultArray;

                var fFiledInfo = new FieldInformation { DisplayName = "Description", Type = FieldType.Text, Value = Path.GetFileName(fileName) };

                FieldInformation[] fFiledInfoArray = {fFiledInfo};

                var copyresult = copyService.CopyIntoItems(destURL, destinationUrl, fFiledInfoArray, File.ReadAllBytes(fileName), out cResultArray);
                var b = copyresult;
            }
            catch (Exception ex)
            {
            }
        }

I receive the error "Object Moved". The URL loads the WSDL in the browser though. If there is a better way to upload and get files from SharePoint on Office365 online I would entertain that as well. Thanks.

回答1:

as the ASMX webservices are deprecated you should check out the "new" rest services of sharepoint. ON MSDN you find information about it

Or you can use the Client object model which would be my favorite way. The following example shows basic usage, to connect to SharePoint online check out the following link

using(ClientContext context = new ClientContext("http://yourURL"))
{
Web web = context.Web;
FileCreationInformation newFile = new FileCreationInformation();
newFile.Content = System.IO.File.ReadAllBytes(@"C:\myfile.txt");
newFile.Url = "file uploaded via client OM.txt";
List docs = web.Lists.GetByTitle("Documents");
Microsoft.SharePoint.Client.File uploadFile = docs.RootFolder.Files.Add(newFile);   
context.ExecuteQuery();
}

Using roqz suggestions above, here is the ultimate solution I came up with to place files in the SharePoint 2013 Office 365 document library and to retrieve them by name:

public void SaveFileToSharePoint(string fileName)
{
    using (var context = new ClientContext("https://mydomain.com/"))
    {
        var passWord = new SecureString();
        foreach (var c in "MyPassword") passWord.AppendChar(c);
        context.Credentials = new SharePointOnlineCredentials("[e-mail]", passWord);
        var web = context.Web;
        var newFile = new FileCreationInformation {Content = File.ReadAllBytes(fileName), Url = Path.GetFileName(fileName)};
        var docs = web.Lists.GetByTitle("Documents");
        docs.RootFolder.Folders.GetByUrl("Test").Files.Add(newFile);
        context.ExecuteQuery();
    }
}

public void GetFileFromSharePoint(string fileName, string savePath)
{
    using (var context = new ClientContext("https://mydomain.com/"))
    {
        var passWord = new SecureString();
        foreach (var c in "MyPassword") passWord.AppendChar(c);
        context.Credentials = new SharePointOnlineCredentials("[e-mail]", passWord);
        var web = context.Web;
        var myFile = web.Lists.GetByTitle("Documents").RootFolder.Folders.GetByUrl("Test").Files.GetByUrl(fileName);
        context.Load(myFile);
        context.ExecuteQuery();

        using (var ffl = Microsoft.SharePoint.Client.File.OpenBinaryDirect(context, myFile.ServerRelativeUrl))
        {
            using (var destFile = File.OpenWrite(savePath + fileName))
            {
                var buffer = new byte[8*1024];
                int len;
                while ((len = ffl.Stream.Read(buffer, 0, buffer.Length)) > 0)
                {
                    destFile.Write(buffer, 0, len);
                }
            }
        }
    }
}
