以编程方式对上传的共享点文档应用权限
我正在开发一个接口来从共享点检索文件。我有以下方法来上传文档:
public bool UploadDocument(string document)
{
if (String.IsNullOrEmpty(Path.GetFullPath(document)))
{
return false;
}
var site = GetNewDataContext(SiteUrl);
try
{
using (var clientContext = GetNewContext())
{
var uploadLocation = string.Format("{0}{1}/{2}", SiteUrl, Helpers.ListNames.RequestedDocuments, Path.GetFileName(document));
//Get Document List
var documentslist = clientContext.Web.Lists.GetByTitle(Helpers.ListNames.RequestedDocuments);
var fileCreationInformation = new FileCreationInformation
{
Content = System.IO.File.ReadAllBytes(document), //Assign to content byte[] i.e. documentStream
Overwrite = true, //Allow owerwrite of document
Url = uploadLocation //Upload URL
};
var uploadFile = documentslist.RootFolder.Files.Add(fileCreationInformation);
uploadFile.ListItemAllFields.Update();
clientContext.ExecuteQuery();
}
site.SubmitChanges(ConflictMode.FailOnFirstConflict, true);
}
catch (Exception exception)
{
throw new ApplicationException(exception.Message);
}
return true;
}
但是,我的下一步是应用自定义权限..我在网上找到了一些博客,演示了如何执行此操作: http://howtosharepoint.blogspot.com/2010/10 /programmatically-add-delete-modify-item.html
- 是否可以在上传过程中设置权限?
- 我的理解是,当文件上传时,它会继承上传到的列表的权限。
- 我当前的下载方法返回一个 ListItem。是否可以将 ListItem 转换为 SPListItem?返回 SpListItem 的原因是由于我上面发布的博客.. 看来 SPListItem 包含我需要的权限信息 [打破并应用新权限]。
我的下载方法返回一个 ListItem..我怎样才能将其作为 SPListItem 执行此操作,
private static ListItemCollection GetListItemCollectionFromSp(string documentListName, string name, string value, string type, int rowLimit)
{
ListItemCollection listItems = null;
using (var ctx = GetNewContext())
{
var documentsList = ctx.Web.Lists.GetByTitle(documentListName);
var camlQuery = new CamlQuery
{
ViewXml =
@"<View>
<Query>
<Where>
<Eq>
<FieldRef Name='" + name + @"'/>
<Value Type='" + type + "'>" + value + @"</Value>
</Eq>
</Where>
<RowLimit>" + rowLimit + @"</RowLimit>
</Query>
</View>"
};
listItems = documentsList.GetItems(camlQuery);
ctx.Load(documentsList);
ctx.Load(listItems,
items => items.IncludeWithDefaultProperties(
item => item.DisplayName));
ctx.ExecuteQuery();
}
return listItems;
}
提前致谢
i'm developing an interface to retrieve a file from sharepoint. i have the following method to upload a document:
public bool UploadDocument(string document)
{
if (String.IsNullOrEmpty(Path.GetFullPath(document)))
{
return false;
}
var site = GetNewDataContext(SiteUrl);
try
{
using (var clientContext = GetNewContext())
{
var uploadLocation = string.Format("{0}{1}/{2}", SiteUrl, Helpers.ListNames.RequestedDocuments, Path.GetFileName(document));
//Get Document List
var documentslist = clientContext.Web.Lists.GetByTitle(Helpers.ListNames.RequestedDocuments);
var fileCreationInformation = new FileCreationInformation
{
Content = System.IO.File.ReadAllBytes(document), //Assign to content byte[] i.e. documentStream
Overwrite = true, //Allow owerwrite of document
Url = uploadLocation //Upload URL
};
var uploadFile = documentslist.RootFolder.Files.Add(fileCreationInformation);
uploadFile.ListItemAllFields.Update();
clientContext.ExecuteQuery();
}
site.SubmitChanges(ConflictMode.FailOnFirstConflict, true);
}
catch (Exception exception)
{
throw new ApplicationException(exception.Message);
}
return true;
}
However, my next step is to apply a custom permission.. i've found some blogs online which demonstrate how to do this:
http://howtosharepoint.blogspot.com/2010/10/programmatically-add-delete-modify-item.html
- Is it possible to set the permission in the uploading process?
- my understanding is, when the file is uploaded it inherits permissions from the list its uploaded to.
- my current download method returns a ListItem.. Is it possible to cast a ListItem to SPListItem? The reason for returning a SpListItem is due to the blog i posted above.. it appears SPListItem contains the permission info i need [to break and apply the new permission to].
my download method returns a ListItem.. how can i do this as an SPListItem
private static ListItemCollection GetListItemCollectionFromSp(string documentListName, string name, string value, string type, int rowLimit)
{
ListItemCollection listItems = null;
using (var ctx = GetNewContext())
{
var documentsList = ctx.Web.Lists.GetByTitle(documentListName);
var camlQuery = new CamlQuery
{
ViewXml =
@"<View>
<Query>
<Where>
<Eq>
<FieldRef Name='" + name + @"'/>
<Value Type='" + type + "'>" + value + @"</Value>
</Eq>
</Where>
<RowLimit>" + rowLimit + @"</RowLimit>
</Query>
</View>"
};
listItems = documentsList.GetItems(camlQuery);
ctx.Load(documentsList);
ctx.Load(listItems,
items => items.IncludeWithDefaultProperties(
item => item.DisplayName));
ctx.ExecuteQuery();
}
return listItems;
}
thanks in advance

看起来您正在尝试在文档库中配置项目级别权限。如果我错了请纠正我。
首先,您必须停止从父站点继承权限。然后,您可以创建一个工作流程并让它在上传文档时触发。设计一个工作流程来配置项目级别的权限比在代码中进行要容易。维护也会很容易。
Looks like you are trying to configure item level permissions in document library. Correct me if I am wrong.
Firstly, You have to stop inheriting permissions from parent site. You can then create a workflow and let it trigger when a document is uploaded. It is easy to design a workflow to configure permissions on item level than doing it in code. Maintenance would be easy too.
