如何在 .asmx Web 服务中创建 ClientContext

Question

I 成功在线连接

list.Credentials = new System.Net.NetworkCredential("domain\username", "password");

但无法加入ClientContext web service：我收到错误 401。如何使用此代码将新项目添加到远程 SPSite 上的 SPList？我需要修复什么？谢谢。

public void UpdateSPList(string Title)
{
    using (AuthenticationSvc.Authentication authSvc = new AuthenticationSvc.Authentication())
    {
        try
        {
            using (ListsSvc.Lists list = new ListsSvc.Lists())
            {
                list.Url = @"http://example-site.com/_vti_bin/Lists.asmx";
                list.CookieContainer = new System.Net.CookieContainer();
                list.AllowAutoRedirect = true;
                list.PreAuthenticate = true;
                list.Credentials = new System.Net.NetworkCredential("domain\username", "password"); 
                string siteUrl = "http://example-site.com";
                ClientContext context = new ClientContext(siteUrl);
                List announcementsList = context.Web.Lists.GetByTitle("ListName");
                ListItemCreationInformation itemCreateInfo = new ListItemCreationInformation();
                ListItem newItem = announcementsList.AddItem(itemCreateInfo);
                newItem["Title"] = "New Item";
                newItem.Update();
                context.ExecuteQuery();
            }
        }
        catch (Exception ex)
        {
            string errorEntry = ex.Message;
        }
    }
}

可以使用 UpdateListItems 方法将新项插入到 SharePoint 列表中。您必须将cmd属性设置为"新建"。

public static XmlNode UpdateListItemInsert()
{
            listservice.Lists listProxy = new listservice.Lists();
            string xml = "<Batch OnError='Continue'><Method ID='1' Cmd='New'><Field Name='ID'/><Field Name='usercol'>-1;#BASESMCDEV2\testmoss</Field></Method><Method ID='2' Cmd='New'><Field Name='ID'/><Field Name='usercol'>-1;#BASESMCDEV2\testmoss</Field></Method></Batch>";

            XmlDocument doc = new XmlDocument();
            doc.LoadXml(xml);
            XmlNode batchNode = doc.SelectSingleNode("//Batch");

            listProxy.Url = "http://basesmcdev2/sites/tester1/_vti_bin/lists.asmx";
            listProxy.UseDefaultCredentials = true;
            XmlNode resultNode = listProxy.UpdateListItems("custom1", batchNode);
            XElement e = XElement.Parse(resultNode.OuterXml);
            var id = from t in e.Descendants().Attributes("ows_ID") select t.Value;

            return resultNode;
}
