Sharepoint 2013 客户端对象模型文件大于 2 Mb 异常

Question

我是 Sharepoint 和客户端对象模型的新手。我遇到了一个问题，无法解决这个问题。我想在 Sharepoint 2013 中使用客户端对象模型上传超过 10 MB 的文件。我得到以下异常

The request message is too large. The server does not allow messages that are larger than 2097152 bytes.

我什么都试过了。这是我做过的事情的 list

1- 更改了我本地 Web 应用程序的 web.config 文件中的设置

<system.web>
<httpRuntime useFullyQualifiedRedirectUrl="true" maxRequestLength="2147483647" requestLengthDiskThreshold="2147483647" executionTimeout="18000"/> </system.web>

<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="2147483647" />
</requestFiltering>
</security>
</system.webServer>

2- 在我服务器的 powershell 中运行以下命令并重新启动 IIS 中的应用程序。甚至重新启动了整个 IIS。

$ws = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$ws.ClientRequestServiceSettings.MaxReceivedMessageSize = 2147483647
$ws.Update()

这是我的代码:

private void UploadDataToSharepointTest(List<UploadData> pDataObjList)
    {
        string lServerUrl = @"http://xxxxxxx:2000/";
        string lFolderName = DateTime.Now.ToString(@"yyyyMMddHHmmss");


        ClientContext context = new ClientContext(lServerUrl);
        context.AuthenticationMode = ClientAuthenticationMode.Default;
        context.Credentials = new System.Net.NetworkCredential("user", "password", "domain");        

        Web web = context.Web;
        List docs = web.Lists.GetByTitle("ABC");
        Folder lNewFolder = web.Folders.Add(lServerUrl + "ABC/" + lFolderName + "/");
        docs.Update();

        int fileIndex = 1;
        foreach (var item in pDataObjList)
        {
            FileCreationInformation newFile = new FileCreationInformation();
            newFile.Content = System.IO.File.ReadAllBytes(item.CompleteFilePath);
            newFile.Url = fileIndex.ToString() + "-" + item.fileName;
            fileIndex++;

            Microsoft.SharePoint.Client.File uploadFile = lNewFolder.Files.Add(newFile);

            context.Load(uploadFile);
            context.ExecuteQuery();

            Dictionary<string, string> metadata = new Dictionary<string, string>();
            metadata.Add("Comments", item.comments);
            metadata.Add("Plan_x0020_Size", item.planSize);
            metadata.Add("Density", item.density);
            metadata.Add("First_x0020_Name", txtFirstName.Text.Trim());
            metadata.Add("Last_x0020_Name", txtLastName.Text.Trim());
            metadata.Add("Company", txtCompany.Text.Trim());
            metadata.Add("Contact", txtContact.Text.Trim());
            metadata.Add("Additional_x0020_Comments", txtAdditionalComments.Text.Trim());

            Microsoft.SharePoint.Client.ListItem items = uploadFile.ListItemAllFields;
            context.Load(items);
            context.ExecuteQuery();

            foreach (KeyValuePair<string, string> metadataitem in metadata)
            {
                items[metadataitem.Key.ToString()] = metadataitem.Value.ToString();
            }

            items.Update();
            context.ExecuteQuery();
        }

    }

注意:我可以上传小文件。

Answer 1

如果使用内置上传功能，文件大小有限制。

要上传大文件，请使用文件流上传。
