概要

接下来我们介绍Lists.UpdateListItems 在更新 item做法和UserGroup.GetUserCollectionFromSite()的用法,请先学习步步为营 SharePoint 开发学习笔记系列 八、SharePoint web service 开发(上),你将更容易学习web service的开发

Lists.UpdateListItems的用法

更新普通list的item的xml格式

<Batch OnError="Continue" ListVersion="1"
ViewName="270C0508-A54F-4387-8AD0-49686D685EB2">
<Method ID="1" Cmd="Update">
<Field Name="ID">4<Field>
<Field Name="Field_Name">Value</Field>
</Method>
<Method ID="2" Cmd="Update">
<Field Name="ID" >6</Field>
<Field Name="Field_Name">Value</Field>
</Method>
</Batch>

更新folder的item的xml格式

<Batch OnError="Continue" PreCalc="TRUE"
ListVersion="0"
ViewName="{EF2F5A21-0FD0-4654-84ED-112B4F5A48F8}">
<Method ID="1" Cmd="Update">
<Field Name="ID">3</Field>
<Field Name="owshiddenversion">1</Field>
<Field Name="FileRef"> http://Server/[sites/][Site/]Shared Documents/Folder</Field>
<Field Name="FSObjType">1</Field>
<Field Name="BaseName">Name</Field>
</Method>
</Batch>

更新documents的item的xml格式

<Batch OnError="Continue" PreCalc="TRUE"
ListVersion="0"
ViewName="{EF2F5A21-0FD0-4654-84ED-112B4F5A48F8}">
<Method ID="1" Cmd="Update">
<Field Name="ID">2</Field>
<Field Name="owshiddenversion">1</Field>
<Field Name="FileRef"> http://Server/[sites/][Site/]Shared Documents/File</Field>
<Field Name="BaseName">Name</Field>
</Method>
</Batch>

我们更新item时xml格式的处理

/// <summary>
/// Get the approved XML Node that will be used for the insert method of the webservice
/// </summary>
/// <param name="batch"></param>
/// <returns></returns>
private XmlNode GetUpdateXmlNode(List<ListItemBE> batch)
{
StringBuilder xml = new StringBuilder();

xml.Append(@"<Batch OnError=""Continue"">");
foreach (ListItemBE listItem in batch)
{
xml.AppendFormat(@"<Method ID=""{0}"" Cmd=""Update"">", listItem.Id);
xml.Append(GetFieldInnerXml(listItem));
xml.Append("</Method>");
}
xml.Append("</Batch>");

//Get the Batch node
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml.ToString());

XmlNode batchNode = doc.SelectSingleNode("//Batch");
return batchNode;
}

更新item时调用sharepoint的web service的处理

/// <summary>
/// Insert the items
/// </summary>
/// <param name="batch"></param>
/// <returns></returns>
private UpdateResultBE UpdateItems(List<ListItemBE> batch)
{
//Get the Insert XML Node
XmlNode batchNode = GetUpdateXmlNode(batch);
XmlNode result = null;

_logger.Log("Started batch updating list Items");
try
{
//Call the webservice
result = _ws.UpdateListItems(_listProperty.ListName, batchNode);
}
catch (Exception ex)
{
_logger.Log(String.Format("Error updating Items. Exception: {0}. Stack Trace: {1}", ex.Message, ex.StackTrace));
}

_logger.Log("Finished batch updating list items");

//Transform the result into an object

UpdateResultBE insertResult = new UpdateResultBE(result, _listProperty);
LogInsertResult(insertResult);

return insertResult;
}

UserGroup.GetUserCollectionFromSite用法

首先建立web service的连接,代码如下

public static SPUserGroupWS.UserGroup GetUserGroupWebService(ListBE listProperty)
{
string wsUrl = GetWSUrl(listProperty) + "_vti_bin/usergroup.asmx";
SPUserGroupWS.UserGroup ws = new SPUserGroupWS.UserGroup();
ws.Url = wsUrl;
ws.UseDefaultCredentials = true;
ws.Credentials = WSHelper.GetCredentials(listProperty.Type);
return ws;
}

我们只取两个简单的字段做个示范

public class UserInfoBE
{
public string ID { get; set; }
public string NTLoginName { get; set; }
}

获取本站点用户列表的方法

public List<UserInfoBE> GetUserInfoList()
{
List<UserInfoBE> userInfoList = new List<UserInfoBE>();
UserInfoBE listItem;

XmlNode nodes = ws.GetUserCollectionFromSite();
foreach (XmlNode node in nodes)
{
if (node.Name == "Users")
{
for (int i = 0; i < node.ChildNodes.Count; i++)
{
if (node.ChildNodes[i].Name == "User")
{
listItem = new UserInfoBE();
listItem.ID = node.ChildNodes[i].Attributes["ID"].Value;
listItem.NTLoginName = node.ChildNodes[i].Attributes["LoginName"].Value;
userInfoList.Add(listItem);
}
}
}
}
return userInfoList;
}

这样就可以通过web service获取站点用户列表信息，但要注意的是，web service的用户名和密码必须是sharepoint站点的管理员.

总结

学会sharepoint的web service用户对在做sharepoint站点的数据迁移时很有帮助。
